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.
Peritonitis is an inflammation (irritation) of the peritoneum. This is the thin tissue that lines the inner wall of the abdomen and covers most of the abdominal organs. Peritonitis is caused by a collection of blood, body fluids, or pus in the belly (abdomen). One type is called spontaneous bacterial peritonitis (SPP). It occurs in people with ascites. Ascites is the buildup of fluid in the space between the lining of the abdomen and the organs.
