includes the brain and spinal cord
central nervous system
includes the 12 pairs of cranial nerves and 31 pairs of peripheral spinal nerves
peripheral nervous system
one or more bundles of neurons that connect the brain and the spinal cord with other parts of the body
nerve
a bundle or group of nerve fibers located within the brain or spinal cord
tract
a nerve center made up of a cluster of nerve cell bodies outside the central nervous system
ganglion
supply of nerves to a specific body part
innervation
network of intersecting spinal nerves
plexus
sites in the sensory organs that receive external stimulation
receptors
anything that excites a nerve and causes an impulse
stimulus
an automatic, involuntary response to some change
reflex
aka sensory neurons
afferent neurons
aka associative neurons
connecting neurons
aka motor neuronsq
efferent neurons
basic cells of the nervous system
neurons
the root-like processes that receive impulses and conduct them to the cell body
dendrites
process that conducts impulses away from the nerve cell
axon
branching fibers at the end of the axon that lead the nervous impulse from the axon to the synapse
terminal end fibers
the space between two neurons or between a neuron and a receptor organ
synapse
chemical substances that make it possible for messages to cross from the synapse of a neuron to the target receptor
neurotransmitters
provide support and protection for neurons
glial cells
the protective covering made of glial cells
myelin sheath
the system of membranes that enclose the brain and spinal cord
meinges
the thick, though, outermost membrane of the meninges
dura mater
resembles a spiderweb, the second layer of the meninges
arachnoid membrane
third layer of the meninges, located nearest the brain
pia mater
produced by special capillarries within the four ventricles. clear, colourless watery fluid that flows throughout the brain and around the spinal cord
cerebrospinal fluid
largest and uppermost portion of the brain
cerebrum
means pertaining to the cerebrum or brain
cerebral
made of gray matter, outer layer of the cerebrum
cerebral cortex
located below the cerebrum, relays sensory stimuli from the spinal cord and midbrain to the cerebral cortex
thalamus
located below the thalamus, controls vital body functions
hypothalamus
located in the lower back of the cranium below the cerebrum, controls balance, etc
cerebellum
located in the base of the brain and forms the connection between the brain and spinal cord
brainstem
cerebral hemispheres subdivided to create pairs of
cerebral lobes
provide conduction pathways to and from the higher and lower centers in the brain, also control reflexes for movements the eyes and head (2 structures)
midbrain and pos
located at the lowest part of the brainstem, is connected to the spinal cord. controls basic survival functions
medulla oblongata
long, tube-like structure that begins at the end of the brainstem and continues down to the bottom of the spinal column
spinal cord
12 pairs of nerve that originate from the undersurface of the brain
cranial nerves
31 pairs of peripheral nerves
peripheral spinal nerves
organized into two divisions, sympathetic and parasympathetic
autonomic nervous system
prepare the body for emergencies and stress
sympathetic nerves
return the body to normal after a response to stress
parasympathetic nerves
a physician who specializes in administering anesthetic agents
anesthesiologist
medical professional who specializes in administering anesthesia but is not a physician
anesthetist
physician who specializes in diagnosing and treating diseases of the nervous system
neurologist
physician who specializes in surgery of the nervous system
neurologist
physician who specializes in diagnosing and treating chemical dependencies, emotional problems, and mental illness
psychiatrist
not an MD, evaluates and treats emotional problems and mental illness
psychologist
aka headache
cephalalgia
characterized by throbbing pain on one side of the head, sometimes accompanied by nausea, vomiting, and sensitivity to light
migraine headache
intensely painful headaches that affect one side of the head and may be associated with tearing of the eyes and nasal congestion
cluster headaches
aka craniocele, congenital herniation of brain tissue through a gap in the skull
encephalocele
congenital herniation of the meninges through a defect in the skull or spinal column
meningocele
condition in which excess cerebrospinal fluid accumulates in the ventricles
hydrocephalus
common, slow-growing usually benign tumor of the meninges
meningioma
inflammation of the menenges brain and spinal cord
meningitis
describes the mental activities associated with thinking, learning, and memory
cognition
slowly progressive decline in mental abilities
dementia
form of dementia caused by a stroke or other restrictions of the flow of blood to the brain
vascular dementia
an inflammation of the brain
encephalitis
potentially serious disorder in children that is characterized by vomiting and confusion
Reye’s syndrome
aka lockjaw, infection of the central nervous system caused by a toxin produced by the tetanus bacteria
tetanus
complex neurological disorder characterized by involuntary tics
Tourette syndrome
umbrella term or disorders in which there is a progressive loss of the structure or function of the neurons
neurodegenerative disease
group of disorders involving the parts of the brain that control thought, memory, and language
Alzheimer’s disease
chronic, degenerative central nervous disorder characterized by fine muscle tremors, rigidity and slow gait
Parkinson’s disease
memory disturbance characterized by total or partial inability to recall past experiences
amnesia
violent shaking up or jarring of the brain
concussion
bruising of brain tissue as the result of a head injury that causes the brain to bounce against the rigid bone of the skull
cerebral contussion
collection of blood trapped in the tissues of the brain
cranial hematoma
blow to the head or a penetrating head injury that damages the brain
traumatic brain injury
describes the results of child being violently shaken by someone
shaken baby syndrome
describes the measurement of response to arousal and stimulus
levels of consciousness
