Muscles and the Skeletal System - Essay Example Muscles connect to the bones through tendons and these connect with other bones through ligaments at the joint. Slight muscle contraction can produce a wide movement (Gregory & Stewart, 2004). Skeletal muscles also maintain and produce body heat by squeezing the veins to help blood flow to heart. Signaling involves the nerve impulses travelling between the brains. Neurons consist of a cell body and appendages that transmit impulses. They act as conduits for signals throughout the nervous system. Nerve impulses are brief changes in the membrane, growing from the movement of ions across the plasma membrane. These potentials are achieved when the sodium-potassium pump in nerve tissues and the calcium pump in muscle tissues (n.d, 2012).

Particularly, prosimians are small tree inhabitants and tarsioids are small primates with features those of the prosimians and the anthropoids.
