REM sleep - Answers Beta waves, rapid movement, diminished activity, increased and variable vital signs
and increased brain activity
sleep disorders and cerebrovascular accidents. - Answers hindbrain is affected by what disorders
brain and spinal cord - Answers CNS is compromised of
hindbrain, midbrain, and forebrain - Answers Brain is divided into 3 regions
cerebellum, pons, and medulla oblongata - Answers Hindbrain consists of the:
movement, posture, and regulation of major body functions like respiration and blood circulation -
Answers hindbrain is responsible for
cerebral pednucles (bundles of nerve fibers that make up corticospinal tracts) - Answers Midbrain home
to
eye movement and visual and auditory processes - Answers midbrain regulates
Diencephalon and cerebral hemispheres - Answers Forebrain consists of
thalamus and subthalamus located in the dorsal horn and hypothalamus in the ventral horn - Answers
Diencephalon consists of
Frontal lobe - Answers primary motor cortex, which is responsible for the precise movements of the
hands and feet and is involved in the planning of learned motor activity
Parietal lobe - Answers primary somatosensory cortex and the somesthetic association cortex which act
to receive sensory information
temporal lobe - Answers primary auditory cortex, which receives auditory input and discriminates
sounds coming in both ears
occipital lobe - Answers primary visual cortex and the visual association cortex. It is here that visual
input is received, processed, and interpreted.
Basal ganglia - Answers masses of white matter located deep to cerebal cortex. Carry out unlearned
postural movements for overall mobility. Affected in parkinsons disease
limbic system - Answers control of emotion related behavior
spinal cord - Answers Divided into white and grey matter. Receives sensory information from periphery
by way of afferent neurons to be transmitted and interpreted
ventral horns - Answers contain efferent neurons which carry motor information from the CNS back to
the periphery
, bony structure of the vertebral column - Answers The spinal cord and nerves are protected by:
The meninges - Answers connective tissue membranes that cover the brain and spinal cord
pia mater - Answers Innermost layer of the meninges that contains surface blood vessels that perfuse
the brain and spinal cord
arachnoid layer - Answers THe second layer of the meninges that encases the entire CNS, nonvascular
and waterproof
Subarachnoid space - Answers where the cerebrospinal fluid circulates
dura mater - Answers strong, continuous connective sheath that provides the brain and spinal cord with
most of its protection
cerebrospinal fluid - Answers serves as a cushion for the brain and spinal cord, protecting them from
outside physical force.
ependyma - Answers a thin layer of neuroglial cells that lines the ventricles of the brain and the central
canal of the spinal cord.
choroid plexus - Answers specialized cells the project into the ventricles ad produce CSF
foramina - Answers small openings that allow the CSF to pass into the subarachnoid space where it will
bathe the brain and spinal cord
PNS - Answers Made up of nerves and ganglia located outside the CNS and includes the 12 pairs of
cranial nerves
Cranial nerve 1 - Answers olfactory (sense of smell)
CN 2 - Answers optic nerve (sense of sight)
CN3 - Answers oculomotor nerve- pupillary constriction, eye movement and eyelid movement
CN4 - Answers trochlear- movement of eye down and inward
CN 5 - Answers trigeminal nerve (mastication)
CN 6 - Answers Abducens (lateral eye movement)
CN 7 - Answers Facial (expressions)
CN 8 - Answers Vestibulocochlear (sense of hearing)
CN 9 - Answers Glossopharyngeal (swallowing)
CN 10 - Answers Vagus (digestion, regulation of heart rate)
