The skeletal system serves many important functions; it provides the shape and form for the body, support and protection, allows bodily movement, produces blood for the body, and stores minerals. [4] The number of bones in the human skeletal system is a controversial topic.
Movement is powered by skeletal muscles, which are attached to the skeleton at various sites on bones. Muscles, bones, and joints provide the principal mechanics for movement, all coordinated by the nervous system. It is believed that the reduction of human bone density in prehistoric times reduced the agility and dexterity of human movement.
The muscular system is an organ system consisting of skeletal, smooth, and cardiac muscle. It permits movement of the body, maintains posture, and circulates blood throughout the body. [ 1 ] The muscular systems in vertebrates are controlled through the nervous system although some muscles (such as the cardiac muscle ) can be completely autonomous.
A skeleton is the structural frame that supports the body of most animals.There are several types of skeletons, including the exoskeleton, which is a rigid outer shell that holds up an organism's shape; the endoskeleton, a rigid internal frame to which the organs and soft tissues attach; and the hydroskeleton, a flexible internal structure supported by the hydrostatic pressure of body fluids.
Various bones of the human skeletal system. The axial skeleton, comprising the spine, chest and head, contains 80 bones. The appendicular skeleton, comprising the arms and legs, including the shoulder and pelvic girdles, contains 126 bones, bringing the total for the entire skeleton to 206 bones.
This system can be split up into the muscular system and the skeletal system. [34] Nervous system ... The functions include the production of germ cells and ...
An organ system is a biological system consisting of a group of organs that work together to perform one or more functions. [1] Each organ has a specialized role in an organism body, and is made up of distinct tissues .
The functions of skeletal muscle include producing movement, maintaining body posture, controlling body temperature, and stabilizing joints. [8] Skeletal muscle is also an endocrine organ . [ 9 ] [ 10 ] [ 11 ] Under different physiological conditions, subsets of 654 different proteins as well as lipids, amino acids, metabolites and small RNAs ...
