nerves
ganglia
Small clusters of nerve cell bodies
Alzheimer disease
Brain disorder marked by gradual progressive mental deterioration, personality changes and impairment of daily functioning
Tourette syndrome
Involuntary, spasmodic, twitching movements; uncontrollable vocal sounds
Parkinson disease
Degeneration of neurons in the basal ganglia occurring later in life and leading to tremors, muscle weakness and slowness of movement
amyotrophic lateral sclerosis (ALS)
Degenerative disorder of motor neurons in spinal cord and brainstem
multiple sclerosis
Destruction of myelin sheath on neurons in the CNS (replacement by plaques of sclerotic tissue)
myasthenia gravis
Autoimmune neuromuscular disorder characterized by weakness of voluntary muscles
spina bifida
Congenital defect in the lumbar spinal column caused by imperfect union of vertebrae may involve myelomeningocele
Huntington disease
Hereditary disorder marked by degenerative changes in the cerebrum leading to abrupt involuntary movements and mental deterioration
epilepsy
Chronic brain disorder characterized by recurrent seizure activity
meningitis
Inflammation of the membranes around the brain and spinal cord
glioblastoma
Abnormal growth of brain tissue (glial cells) and meninges, highly malignant
dementia
Mental decline and deterioration
herpes zoster
Viral infection affecting peripheral nerves marked by eruption of painful blisters also known as shingles
hemiplegia
Paralysis on one side of the body
migraine
Severe recurrent unilateral vascular headache
cerebrovascular accident
Disruption in the normal blood supply to the brain; stroke
cerebral contusion
Bruising of brain tissue as a result of direct trauma to the head
neuropathy
Condition affecting the nerves
paresthesia
Tingling or prickling caused by pressure on or damage to a nerve
cerebral concussion
Traumatic brain injury caused by a blow to the head, no visible evidence of structural damage to brain tissue
HIV encephalopathy
Brain disease occurring with AIDS
syncope
Fainting
aphasia
Difficulty speaking
hydrocephalus
Abnormal accumulation of CSF in the ventricles of the brain
palsy
Paralysis (partial or complete loss of motor function)
aneurysm
Enlarged, weakened area in an artery
embolus
Clot of material that travels through the bloodstream and suddenly blocks a vessel
occlusion
Blockage of a vessel
Explain a synapse and its function
Junction between nerve cells that passes an impulse from axon of one cell to a dendrites of another cell
Differentiate between afferent and efferent neurons
Efferent to CNS and Afferent away from CNS
Explain the layers of the meninges
Dura is tough outer. Arachnoid is middle. Pia is delicate inner
Differentiate between the gyri and sulci of the brain
Rounded folds are gyri. Grooves are sulci
