Explanation Muscular System
Muscles are divided into three types
First: voluntary muscles:
Has been so named because they are subject to movements of the human will, it is also called striated muscle because they look under the microscope to form fibrous lines, and some scientists called Name skeletal muscle due to primarily on the skeleton of the body.
Second of: muscle Allrdaeh:
Any that are moving away from the human will, dubbed the smooth muscle because it does not show any fiber lines under a microscope. There are members follicle shrinking machine such as the stomach, intestines, blood vessels, a woman's uterus, and urinary tract.
Third: the heart muscle:
They have characteristics intermediate between the first two types, as is not Ardaeh but planned.
Muscles and their evolution:
Muscles arise stem structure of muscle coupon positioned along the spine. While arise muscles sides of the middle class, which originate from the bone.
The smooth muscle arises from the primary cells of the central leaflet emerging coupon muscle. As well as heart muscle cells arise from the central leaflet initial intervention in the installation of pipes that will form the heart.
