In vertebrates, skeletal muscle contractions are neurogenic as they require synaptic input from motor neurons to produce muscle contractions. A single motor neuron is able to innervate multiple muscle fibers, thereby causing the fibers to contract at the same time.
periostitis. n. 1. (Anatomy) inflammation of the periosteum.
Etymology: Gk, peri + osteon, bone. a thick, fibrous vascular membrane covering the bones, except at their extremities. It consists of an outer layer of collagenous tissue containing a few fat cells and an inner layer of fine elastic fibers.Periosteum is permeated with the nerves and blood vessels that innervate and nourish underlying bone. specialized connective tissue covering all bones of the body, and possessing bone-forming potentialities. It is made up of an outer tough fibrous layer and a deeper more succulent osteogenic layer. Periosteum also serves as a point of attachment for certain muscles, tendons and ligaments.
