Answer 1

Lymph nodes act as filters, with an internal honeycomb of reticular connective tissue filled with lymphocytes that collect and destroy bacteria and viruses. When the body is fighting an infection, lymphocytes multiply rapidly and produce a characteristic swelling of the lymph nodes.

Lymph nodes are bean-shaped and range in size from a few millimeters to about 1-2 cm in their normal state.

They may become enlarged due to a tumor or infection. White blood cells are located within honeycomb structures of the lymph nodes. White blood cell production increases when the body is infected, and thus the lymph nodes are enlarged. In some cases, which may exist past the throat, they may feel enlarged due to past infections; although one may be healthy, one may still feel residually enlarged.

[edit] Lymph nodes of the head and neck
Cervical lymph nodes
Anterior cervical: These nodes, both superficial and deep, lie above and beneath the sternocleidomastoid muscles. They drain the internal structures of the throat as well as part of the posterior pharynx, tonsils, and thyroid gland.
Posterior cervical: These nodes extend in a line posterior to the sternocleidomastoids but in front of the trapezius, from the level of the Mastoid portion of the temporal bone to the clavicle. They are frequently enlarged during upper respiratory infections.
Tonsillar: These nodes are located just below the angle of the mandible. They drain the tonsillar and posterior pharyngeal regions.
Sub-mandibular: These nodes run along the underside of the jaw on either side. They drain the structures in the floor of the mouth.
Sub-mental: These nodes are just below the chin. They drain the teeth and intra-oral cavity.
Supraclavicular: These nodes are in the hollow above the clavicle, just lateral to where it joins the sternum. They drain a part of the thoracic cavity and abdomen. Virchow's node is a left supraclavicular lymph node which receives the lymph drainage from most of the body (especially the abdomen) via the thoracic duct and is thus an early site of metastasis for various malignancies.

[edit] Lymph nodes of the arm
These drain the whole of the arm, and are divided into two groups, superficial and deep. The superficial nodes are supplied by lymphatics which are present throughout the arm, but are particularly rich on the palm and flexor aspects of the digits.

Superficial lymph glands of the arm:
supratrochlear glands: situated above the medial epicondyle of the humerus, medial to the basilic vein. They drain the C7 and C8 dermatomes.
deltoideopectoral glands: situated between the pectoralis major and deltoid muscles inferior to the clavicle.
Deep lymph glands of the arm: These comprise the axillary glands, which are 20-30 individual glands and can be subdivided into:
lateral glands
anterior or pectoral glands
posterior or subscapular glands
central or intermediate glands
medial or subclavicular glands

Answer 2

First off, the lymphatic system is a lot like your circulatory system, lots of vessels that travel all along your body with little swells that look like beads along the vessels called nodes. In pictures they are usually white. Lymph nodes can get tender when you are fighting an infection because they are a huge part of cleaning up that infection. Ever go to the doctor and he feels your throat under the chin? He's feeling for swolen lymph nodes. They will get bigger when you fight infection. Remember reading about the Bubonic Plague in Medieval times? Peoples lymph nodes grew to huge sizes in the arm pit, the groin and the neck and then turned black. They called the large growths 'bubons', hence the name for the plague. The three areas aforementioned are the areas with the most lymph nodes.

Answer 3

they are white. there are some in the breast/armpit area. They are about the size of mini-marshmallows and they are there to provide lymph, a protective healing agent produced and sent to areas where the skin has been broken. That clear/yellowy stuff on your bandaid when you peel it off? That's lymph.
