Bell's palsy
A weakness or paralysis of the muscles that control expression on one side of the face because of damage to a facial nerve.
brain
The part of the central nervous system inside the skull. Its functions include muscle control and coordination, sensory reception and integration, speech production, memory storage and the elaboration of thought and emotion.
cerebral palsy
A disorder caused by injury to the cerebral area of the brain that occurs before or during birth or in the first few months after birth. Damage to the cerebrum may cause paralysis (palsy) in one or more parts of the body.
hematoma
A collection of blood within the brain or on its surface that can cause increased pressure, which can damage brain cells and interrupt blood flow.
Pfeiffer syndrome
Many of the characteristic facial features of Pfeiffer syndrome result from the premature fusion of the skull bones. The head is unable to grow normally, which leads to bulging and wide-set eyes, an underdeveloped upper jaw, and a beaked nose.
Crouzon syndrome
Many of the signs of Crouzon syndrome result from the early fusion of the skull bones during childhood. Abnormal growth of these bones leads to wide-set, bulging eyes due to shallow eye sockets; eyes that do not point in the same direction (strabismus); a beaked nose; and an underdeveloped upper jaw.
enkephalins
(en-KEF-uh-lins). Naturally occurring molecules in the brain. Enkephalins attach to special receptors in the brain and spinal cord to inhibit pain messages. They also affect other functions within the brain and nervous system.
cerebellum
The portion of the brain mainly responsible for balance and coordination.
amyotrophic lateral sclerosis (ALS)
Also known as Lou Gehrig's disease, ALS causes degeneration of the nerve cells in certain regions of the brain and spinal cord that control the muscles.
