autonomic nervous system ANS
Consist of nerves that regulate involuntary functions. Divided into sympathetic and parasympathetic nervous system
Slender, elongated projection that carries the nervous impulse from the cell body to the next neuron is the ______
axon
What connects the cerebral hemispheres to the spinal cord. Composed of the midbrain, pons, medulla oblongata?
Brainstem
What is composed of the brain and the spinal cord. Only site which contains interneurons?
Central Nervous System (CNS)
The _______ coordinates voluntary movement but is an involuntary in function
cerebellum
Present in cavities of the brain (ventricles) is ______
Cerebrospinal fluid CSF
Largest portion of the brain. Divided into hemispheres (lobes). Responsible for thinking, reasoning, and memory is _______
Cerebrum

cranial nerves
Covering unique to the CNS is ______
meninges
What covers the axon?
myelin sheath
31 pairs of spinal nerves emerge from the spinal cord at the ______
nerve root
Parenchymal cells; that carry out the work of the nervous system are _____
neuron
Located at the synapse of the axon terminal and neuron dendrites is the ________
neruotransmiter
Does the opposite of the sympathetic nervous system. What slows heart rate, lowers blood pressure, increases digestive functions, decreases adrenal and sweat gland activity?
Parasympathetic nervous system
rest and digest system is the ______
parasympathetic nervous syystem
Composed of grey and white matter. Spinal nerves emerge from it at the nerve root is the _____
spinal cord
31 pairs, part of the PNS. Mimic the organization of the vertebrae and provide innervation of the rest of the body is the ______
spinal nerves
What Helps a person respond to perceived stress. Heart rate increases, blood pressure increases, slows digestion, increases sweat and adrenal gland secretions?
sympathetic nervous system
fight or flight is the _______
sympathetic nervous system
the Space where the neurotransmitter is released from the cell to travel across to the next cell is the ______
synapse
Lack of sense of smell, without smell
anosmia
Motor function disorder as a result of permanent, nonprogressive brain defect or lesion caused perinatally is ______
cerebral palsy (CP)
Ischemia of cerebral tissue due to an occlusion/blockage from a thrombus or embolus or a result of a cerebral hemmorage. AKA: stroke, brain attack, and cerebral infarction is______
cerebrovascular accident (CVA)
What is an Incision of the spinal cord to relieve pain
cordotomy
Removal of part of the skull
craniotomy
Record of electrical activity of the brain
electroencephalography
What is inflammation of the brain, most often cause by a mosquito bite?
enecephalitis
Paralysis of the left or right side of the body is _____
hemiplegia
Pertaining to the lower back.
Lumbar puncture
Any infection or inflammation of the membranes covering the brain and spinal cord, most commonly due to viral infection is ______
meningitis
Condition in which the spinal column has an abnormal opening that allows protrusion of the meninges and or the spinal cord is ______
meningomyelocete
Neurodegenerative disease characterized by destruction of the myelin sheaths on the CNS neurons, demyelation, and their abnormal replacement by the gradual accumulation of hardening plaques.

polysomnography PSG
Paralysis of arm legs and trunk is _____
quadriplegia
What is the resection of the dorsal root of a spinal nerve to relieve pain?
rhizotomy
Pain control method effected by the application of electrical impulses to the skin is ____
Transcutaneous electrical nerve stimulation TENS
TIA has the same mechanisms as a CVA but the sequelae resolve and disappear within 24 hrs. ______ is known as a ministroke.
