Adenosine triphosphate (ATP) is considered by biologists to be the energy currency of life. It is the high-energy molecule that stores the energy we need to do just about everything we do.
The basic function of muscle is to generate force. Secondarily, muscles can provide some shape and form to the organism. Anatomically and functionally, muscle can be divided into two types, smooth and striated. Striated or striped muscle can be further divided into skeletal muscle and cardiac (heart) muscle.
Lesson Summary. In summary, skeletal muscles are organs that are directly or indirectly attached to bone. Skeletal muscles serve a variety of functions including support and movement and homeostasis. Skeletal muscle contraction can result in muscle shortening and thus movement of the bone to which it is attached.Additionally, skeletal muscle contraction can maintain posture and position.keletal muscles serve a variety of functions including support and movement and homeostasis.
