what is the relation between muscle structure and its function ?

Question

doing human bio assignment need a simplified answer that can be easily understood

Answer 1

Do your own homework!!!

Answer 2

if you look at the action of the muscle during peristalsis it would become obvious when you see the muscles that are at angles to each other relaxing and contracting to make the bollus move down the ailamentry canal.

Answer 3

Muscle is a contractile tissue of the body and is derived from the mesodermal layer of embryonic germ cells. Its function is to produce force and cause motion, either locomotion or movement within internal organs. Much of muscle contraction occurs without conscious thought and is necessary for survival, like the contraction of the heart or peristalsis, which pushes food through the digestive system. Voluntary muscle contraction is used to move the body and can be finely controlled, such as movements of the finger or gross movements like the quadriceps muscle of the thigh.



There are three types of muscle:

Skeletal muscle or "voluntary muscle" is anchored by tendons to bone and is used to affect skeletal movement such as locomotion and in maintaining posture. Though this postural control is generally maintained as a subconscious reflex, the muscles responsible react to conscious control like non-postural muscles. An average adult male is made up of 40-50% of skeletal muscle and an average adult female is made up of 30-40%.
Smooth muscle or "involuntary muscle" is found within the walls of organs and structures such as the esophagus, stomach, intestines, bronchi, uterus, ureters, bladder, and blood vessels, and unlike skeletal muscle, smooth muscle is not under conscious control.
Cardiac muscle is also an "involuntary muscle" but it's a specialized kind of muscle found only within the heart.
Cardiac and skeletal muscle are "striated" in that they contain sarcomere and are packed into highly-regular arrangements of bundles; smooth muscle has neither. While skeletal muscles are arranged in regular, parallel bundles, cardiac muscle connects at branching, irregular angles. Striated muscle contracts and relaxes in short, intense bursts, whereas smooth muscle sustains longer or even near-permanent contractions.

Skeletal muscle is further divided into several subtypes:

Type I, slow oxidative, slow twitch, or "red" muscle is dense with capillaries and is rich in mitochondria and myoglobin, giving the muscle tissue its characteristic red color. It can carry more oxygen and sustain aerobic activity.
Type II, fast twitch, muscle has three major kinds that are, in order of increasing contractile speed
a) Type IIa, which, like slow muscle, is aerobic, rich in mitochondria and capillaries and appears red.
b) Type IIx (also known as type IId), which is less dense in mitochondria and myoglobin. This is the fastest muscle type in humans. It can contract more quickly and with a greater amount of force than oxidative muscle, but can sustain only short, anaerobic bursts of activity before muscle contraction becomes painful (often incorrectly attributed to a build-up of lactic acid). N.B. in some books and articles this muscle in humans was, confusingly, called type IIB.
c) Type IIb, which is anaerobic, glycolytic, "white" muscle that is even less dense in mitochondria and myoglobin. In small animals like rodents or rabbits this is the major fast muscle type, explaining the pale color of their meat.

Answer 4

bones are made up of lots harder factors and can't be bent surely they're lots extra brittle according to risk the biggest distinction is the molecular shape of cartilage is that of graphite mutually as the form of bones is like diamond additionally cartilage is used as cushioning between bones to maintain them from scraping together cartilage wears away surely think of of it as comparing a diamond tipped cutter head to a chew of solid graphite one is lots extra solid yet damages each little thing the different is lots extra slippery and is stable at cushioning each little thing

Answer 5

the muscle functions according to its structure?
