1. Arthropod- They are the most successful of all animals; there are well over 1,000,000 species, and they compose abour 2/3 of ALL species on the earth. They are segmented animals with jointed appendages. The majority of arthropod species consist of small animals, about 1mm in length. There are adult arthropods of the phylum group that range in size from 80um to 3.6 meters across. Arthropods are insects and are of enormous economic importance and affect all aspects of human life.

2. Arth-joint, jointed- The jointed appendages of insects are all connected to the central body region, the thorax. At the thorax, there are 3 pairs of attached legs and, most oftern, two pairs of wings (some insects, like flies, have only retained one pair of wings). The actual name "arthropod" comes from 2 Greek words: 'arthros,' "jointed" and 'podes,' "feet". All arthropods have jointed apppendages and the number of these appendages decresases in the more advances members of the phylum. Arthropods use jointed appendages such as legs for walkingm antennae to sensetheir environment, and mouthparts for feeding.

3. Pod-Foot- These are the feet of the Arthropods, which they obviously use for the purpose of walking. Insect arthropods generally have three pairs of legs attached to their thorax. Arthropods that are swimmers have uropods that form a sort of paddle at the end of their abdomen, allowing them to swim easily in water.

4. Arthritis- There are 2 forms of arthritis: gonococcal and rheumatoid. Gonococcal arthritis is caused by the Gonorrhea virus, an acute, infectious, sexually transmitted disease of the mucous membranes of the genitourinary tracct, eye, rectum, and throat. The bacteria that cause this infection are the gonococci bacteria. In both males and females, disseminated gonococcal infection with bcateremia may occur. This can lead to involvement of the joints, causing gonorrheal arthritis.
The second, more known, form of arthritis is rheumatoid arthritis which is an auto-immune diease. Rheumatoid arthritis is the result of large antobody-antigen complexes that result in granuloma formations and chronic inflammation. A granuloma forms when macrophages are unable to protect the host from tissue damage and the body attempts to wall off and isolate that site with a granuloma. Rhuematoid arthritis is extremely painful.

5. Pathology- Ther science which treats of diseases, their nature, causes, progress, symptoms, etc. Note: Pathology is general or special according as it treats of disease or morbid processes in general, or of particular diseases; it is also subdivided into internal or external, medical or surgical pathology, departments: {nosology}, {[ae]tiology}, {morbid anatomy}, {symptomology}, {therapeutics}-treat respectively of the classification, causation, organic changes, symptoms, and cure for disease. Definition #2. The condition of an organ, tissue, or fluid produced by a disease
---cellular pathology- theory givning prominance to the vital action of cells in the healthy and deceased functions of the body

6. Antibiotic- A microbial product or it's derivative that kills susceptible microorganisms or inhibits their growth; a protein (immunoglobin), consisting of two identical heavy chains and two identical light chains, that recognize a particualr epitope on an antigen and facilitates clearance of that antigen. Membrane-bound antibody is ecpressed by B-cells that have not encountered an antigen; secreted antibody is produced by plasma cells. Some antibodies are multiples of the basic four-chain structure.

7. Herbicide- Widespread agriculture, carried out increasingly by modern methods, introduces many kinds of new chemicals into the global ecosystem, such as pestricides, herbicides, and fertilizers. Industrialized countries , like the Unites States, are attempting to monitor the side effects of these chemicals. While these toxic molecules may not be used in the US, they are produced in the US and sent to toher countries: chlorinated hydrocarbons, a class of compounds including DDT, chlordane, lindane, and dieldrin. Chlorinates hydrocarbons break down slowly and accumulate in animal fat, and as they pass down the food chain they become more concentrated in a process called chemical magnification. DDT causes problems b/c it encourages the formations of thin, fragile eggs in many predatory bird species in US and esewhere. Chlorinated have other undesirable effects as well: exhibit hormone-like activities in the bodies of animals, disrupt normal hormonal cycles with sometimes very serious consequences.

8. Chloroplast- A cell-like organelle present in algae and plants that containd chlorophyll, and usually some other pigemts. They are responsible for carrying out photosynthesis. It is hypothesized that chlorophylls, similar to what has been hypothesized about eukaryotic mitochondria, were dervided from a photosynthetic prokarytic bacteria that was engulfed by a non-photosynthetic eukaryotic bacteria, and the result was a symbiotic relationship.

9. Erythrocyte- this is a red blood cell (RBC). The red blood cells are produced about every 28 days, and they contain stem cells located in the long bones. Upon maturation, RBC's lose their nucleus and form a bi-concave disc shaped cell. The purpose for this is to allow for the RBCs to pass single file through the 20um diameter capillaries. RBC's also contain hemoglobin, the oxygen containing protein in the blood, and they are responsible for supplying the entire bosy with adequate oxygen.

10. Herpetology - A creeping thing, a reptile; the natual history of reptiles; that branch of Zoology that realtes to reptiles, including their structure, classification, and habits

11. Gametogenesis- the production of gametes (germ cells), the cells of reproduction produced in meiosis that conatin half a persons genetic material (ex: sperm cells in males and ova in females), from a pool of germ cells. In gametogenesis the diploid germ cell undergo a seres of cell divisions that ultimately reduces the number of chromosomes in each cell by half, from 2n to n.

12. External Solution- the ion concentration of external solutions as a characteristic of micro- or nsnogel ionic resevoirs. Ionic resevoirs are ion-sensitive hydrogels. This is a system capable of changing the pH or ionic strength by accumulating or releasing ions. Varying effects of ion concentrations in external solutions can be used to test the effecst of osciallations, or waves, of membrane potentials produced by acetylcholine, a neurotransmitter, or carbachol.
-----the membrane potential of longitudinal cells recorded intracellularly with glass microelectrodes. When the isotonic physiologic salt solution is changed to hypertonic sucrose solution, spontaneous electric activity of the cell membrane will vanish. Use sodium-deficient external solution, result is the loss of the slow waves; use calcium-free external solution and result with getting slow waves after a time period of 20 minutes; use chlorine-deficient external solution and small, but significant small waves occur; use potassium free or potassium rich external solution and result with a high number of small waves in both reaction conditions, with or without the K+. So, slow waves, produced by acetylcholamine or carbachol actually represent an inward sodium current through a slow regenerative ion channel, and this is proven using external solutions.

13.Head-footed - this name refers to the cephalopod family of invertebrate marine species, such as octopus, squid, slugs, snailsm chitons, shellfidh, all collectively knwon as mollusks. The reason the octopus and the squid are called heat-footed is b/c their arms and tenticles are derived from their head. These two organisms represent the pinnacle of invertebrate evolution; they are the most intelligent, and contain some of the heaviest and most aggressive species if all invertebrates. All species of octppus and squid have a mantle, head, and 8 arms, although sometimes the squid will have 2 additional arms. The mantle is a tapered part of the organsism that is a cylindrical organ sac. The heads of these two organisms contain the brain, 2 eyes, a mouth with a beak shaped like a parrot's, and attached to the underneath surface, a muscular funnel for water filtration.

14. Seed Plant- in seed plants, the gametophytes, or the haploid generation, the "gamete plant," are nutritionally dependant on the sporophyte, the diploid generation of the plant cells, also called the "spore plant." Seed plants are enclosed within the tissues of the sporophytes. when one looks at a gymnosperm or angiosperm, what one will see, with rare exception, is a sporophyte.

A


arthritis
1543, from L. arthritis, from Gk. nosos arthritis "disease of the joints," from nosos "disease" + arthritis, fem. of arthrites (adj.) "pertaining to joints" (Gk. nosos is a fem. noun), from arthron "a joint" (see arthropod). Arthritic was used in Eng. as an adj. and a noun from 1366.


pathology
"science of diseases," 1611, from Fr. pathologie, from Mod.L. pathologia, from Gk. pathologikos "treating of disease," from pathos "suffering" (see pathos) + -logia "study," from logos "word." Pathologist first recorded 1650. Pathological "pertaining to disease" formed in Eng. 1688; sense of "worthy to be a subject of pathology, morbid, excessive" (e.g. pathological liar) is attested from 1845.


antibiotic
1894 (adj.), from Fr. antibiotique (c.1889), from anti- + Gk. biotikos "fit for life." As a noun, first recorded 1941, in works of physician Selman Waksman, discoverer of streptomycin

chlo·ro·plast (klôr-plst, klr-) also chlo·ro·plas·tid (klôr-plstd, klr-)
n.
A chlorophyll-containing plastid found in algal and green plant cells.
[chloro- + plast(id).]


erythrocyte, A cell in the blood of vertebrates that transports oxygen and carbon dioxide to and from the tissues. In mammals, the red blood cell is disk-shaped and biconcave, contains hemoglobin, and lacks a nucleus. Also called erythrocyte, red cell, red corpuscle.

B
EXTERNAL SOLUTION

external
1537 (as extern), from L. externus "outside, outward," from exterus (see exterior). This version won out over exterial.
solution
1375, "a solving or being solved," from O.Fr. solucion, from L. solutionem (nom. solutio) "a loosening or unfastening," also "a solving," from pp. stem of solvere "to loosen, untie, solve, dissolve" (see solve). Meaning "liquid containing a dissolved substance" is first recorded 1594.

SEED PLANT

seed (v.)
"to produce seed," c.1374; "to sow with seed," c.1440; from seed (n.). Sporting (originally tennis) sense (1898) is from notion of spreading certain players' names so as to insure they will not meet early in a tournament. The noun in this sense is attested from 1933.
plant (n.)
O.E. plante "young tree or shrub, herb newly planted," from L. planta "sprout, shoot, cutting," perhaps from *plantare "to drive in with the feet, push into the ground with the feet," from planta "sole of the foot," from nasalized form of PIE *plat- "flat" (see place (n.)). Ger. Pflanze, Ir. cland, Welsh plant are from Latin. Broader sense of "any vegetable life" is first recorded 1551. The verb, "put in the ground to grow," is O.E. plantian, from L. plantare, from planta. Most extended usages are from the verbal sense. Sense of a building "planted" or begun for an industrial process is first attested 1789. Slang meaning "a spy" is first recorded 1812. Planter "proprietor of a cultivated estate in W.Indies or southern colonies of N.America" is attested from 1647; hence planter's punch (1924).

HEAD FOOTED

head
O.E. heafod "top of the body," also "upper end of a slope," also "chief person, leader, ruler," from P.Gmc. *khaubuthan (cf. O.S. hobid, O.N. hofuð, O.Fris. haved, Ger. Haupt, Goth. haubiþ "head"), from PIE *kauput- "head" (cf. Skt. kaput-, L. caput "head"), also "bowl" (as in skull). Modern spelling is c.1420, representing what was then a long vowel (as in heat). Meaning "obverse of a coin" is from 1684; meaning "foam on a mug of beer" is first attested 1545; meaning "toilet" is from 1748, based on location of crew toilet in the bow (or head) of a ship. Synechdochic use for "person" (as in head count) is first attested 1535; of cattle, etc., in this sense from 1513. To give head "perform fellatio" is from 1950s. Meaning "drug addict" (usually in a compound with the preferred drug as the first element) is from 1911. The verb head "to shape one's course toward" (1835) was originally nautical. Header "head-first dive or plunge" first attested 1849. Headlight is from 1861, originally of ships and locomotives. Headquarters is from 1647. Headstrong "determined to have one's way" is from 1398. Headroom "space above the head" first recorded 1851. Headphone is 1914, with second element extracted from telephone.
