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.
Pericoronitis is inflammation of the gum tissue surrounding the crown portion of a tooth. Pericoronitis usually affects the lower third molar (wisdom) tooth where gum tissue overlaps the chewing surface of the tooth. Pericoronitis can be either chronic or acute.Chronic pericoronitis is a mild persistent inflammation of the area. Acute pericoronitis is when the symptoms intensify to fever, swelling, and pain, which indicate a spreading infection.Pericoronitis is differentiated from gum disease (or periodontitis) in that it occurs specifically around a partially erupting tooth.The cause of this condition is similar to the formation of a gum abscess in periodontitis by the entrapment of debris under the gum tissue.cute pericoronitis is when the symptoms intensify to fever, swelling, and pain, which indicate a spreading infection.
