birth defect: portion of n.s. protrudes through opening in vertebral column
chronic brain condition
speech and gait disturbances
loss of memory
Amyotrophic lateral sclerosis (ASL)
disease with muscular weakness due to motor neurons of spinal cord, commonly called
Lou Gehrig disease
What is the 2nd largest part of the brain and also coordinate movement and balance?
WHat is the largest part of the brain?
: receive sensory info and sends motor commands
responsible for memory, problem solving, and language

What is the largest organ in the body?
coordinate most body activities
4 sections: cerebrum, cerebellum, thalamus, and brain stem
right side of brain control the left side of the body, left side controls ride side.
____ is part of the brain stem?
Medulla oblongata :
connect rest of brain to spinal cord
has control centers for respiration, HR, Temp, and BP
medication reducing excitability of neurons and prevent activity associated with seizures.
Intracranial mass; either benign or malignant
benign can still be fatal, it can grow and cause pressure on normal brain tissue
bruising of brain, symptoms last longer than 24 hours
include unconsciousness, dizziness, vomiting, unequal pupil size, and shock
Non-progressive brain damage

cerebrospinal fluid analysis
lab exam of clear, watery, colorless fluid from brain and spinal cord
detects infections or bleeding of brain

treated by creating shunt from brain to abdomen to drain excess fluid.
punture usually between 4th and 5th lumbar vertebrae inorder to draw fluid for examination or for injection of medication.
spinal puncture or spinal tap
Inflammatory autoimmune disease of C.N.S
immune system damages myelin around neurons and results in extreme weakness and numbness.

can result in meningocele or myelomeningocele
Mass of blood forming under dura mater when meninges are torn by trauma
can exert fatal pressure on brain if hematoma is not drained by surgery.
Trasient ischemic attack (TIA)
Temporary reduction of blood supply to brain
causes syncope, numbness, and hemiplegia
can eventually lead to cerebrovascular accident.
