muscle tissue 3D 模型

a 3d model of muscle tissue. complete with color map and bump maps. this model is ready for 3d medical animation/presentation. this model is consist of different model conversions such as 3ds, max, maya, lightwave etc. this conversions can be open in any latest or old 3d software package.

medical description:

muscle is the contractile tissue of animals and is derived from the mesodermal layer of embryonic germ cells. muscle cells contain contractile filaments that move past each other and change the size of the cell. they are classified as skeletal, cardiac, or smooth muscles. their function is to produce force and cause motion. muscles can cause either locomotion of the organism itself or movement of internal organs. cardiac and smooth muscle contraction occurs without conscious thought and is necessary for survival. examples are the contraction of the heart and peristalsis which pushes food through the digestive system. voluntary contraction of the skeletal muscles is used to move the body and can be finely controlled. examples are movements of the eye, or gross movements like the quadriceps muscle of the thigh. there are two broad types of voluntary muscle fibers: slow twitch and fast twitch. slow twitch fibers contract for long periods of time but with little force while fast twitch fibers contract quickly and powerfully but fatigue very rapidly. 打印准备: 否
