Nervous System Divisions
The brain and spinal cord make up this branch of the nervous system
Central nervous system
The basic structural unit of the nervous system.....
the neuron
The membranes covering the brain and spinal cord are called ______________________
meninges
Abnormal electrical impulses in the brain cause this seizure disorder, also known as...
epilepsy
Largest part of the brain, where reasoning, thought, speech, sight are controlled
cerebrum
The two main divisions/branches of the nervous system :
central and peripheral nervous system
The ______________ is a space between the axon of one neuron and the dendrites of the next neuron.
synapse
Hollow spaces in the brain filled with cerebrospinal fluid are called:
ventricles
Disturbance in movement of voluntary muscles that can be caused by brain damage to the fetus during pregnancy or delivery
cerebral palsy
The part of a neuron that carries the impulse/message away from the cell body
Axon
The subdivision of the nervous system responsible for the 'fight or flight' response.............
sympathetic nervous system
Part of a nerve fiber/neuron that receives the impulse/message and carries it toward the cell body:
dendrites
The part of the brain responsible for balance, posture, muscle coordination
cerebellum
Degenerative muscle disorder which results in eventual loss of all muscles but does not affect the mind
Lou Gehrig's disease/ALS
Chemicals at the end of nerves that carry the message across the synapse to the next nerve
neurotransmitters
The subdivision of the nervous system responsible for the 'rest and digest' response...............
parasympathetic nervous system
Part of the brain the helps control/regulate your heartbeat, respirations and blood pressure; lowest part of the brainstem
medulla oblongata
The innermost membrane covering the brain is spinal cord: dura mater - pia mater - or arachnoid
pia mater
Paralysis of all four extremities
quadriplegia
Excessive amount of CSF in the brain's ventricles
hydrocephalus
The two main division of the peripheral nervous system ...........................
Somatic and autonomic nervous systems/divisions
Cranial and spinal nerves are part of which section/division of the nervous system?
peripheral nervous system
Which of these brain parts is not part of the brainstem?medulla oblongata; pons; hypothalamus; midbrain
hypothalamus
Inflammation of the brain often caused by a virus transmitted by a mosquito bite
encephalitis
Damage to the brain from hemorrhage (excessive blood loss) or a blood clot; commonly called a stroke
