Babble or Speech
Autonomic nervous system
Controls involuntary responses; consists of Sympathetic division and Parasympathetic division
Basal Ganglia
Linked to the thalamus at the base of the brain, involved in the coordination of movement.
Cauda Equina
Consists of the second through fifth lumbar nerves, five sacral nerves, and the coccygeal nerve.
Central Nervous System
Consists of brain and spinal cord
Craniotomy
Surgical opening into the skull
Definition: Transsphenoidal Hypophysectomy
Removal of pituitary tumors
Discectomy
Surgical excision of an intervertebral disc
Epidural
Pertaining to above or outside the dura mater
Gray matter
Axons that are not covered in myelin
Hemiparesis
Paralysis on one side of the body
Hemiparesis
Weakness on one side of the body
Intrathecal administration
Injection into the spinal canal or subarachnoid space
Laminae
Small ridged areas midway between the spinous process, the transverse process and the vertebral arch.
Laminectomy
Removal of the laminae and the entire posterior portion of the vertebra
Laminotomy
Partial excision of one or lamina for nerve decompression
Medulla Oblongata
Bundle of nerves that extend from the base of the brain downward to the conus medullaris
Most common disability following stroke
Hemiplegia - complete paralysis on one side of the body
Most prevalent type of stroke
Ischemic
Myelin
Substance that covers some axons to insulate protect and assist in electrical conduction
Nerve Cell Anatomy
Nucleus surrounded by soma with dentrites emerging. Axion consists of Scwann cells in myelin ending in axon terminal
