COMPLETE SOLUTIONS
pia mater - ANSWER-thin, delicate inner membrane of the meninges
Hematoma - ANSWER-a solid swelling of clotted blood within the tissues.
subdural hematoma - ANSWER-Slowly expanding with venous blood
Epidural - ANSWER-Rapidly expanding with arterial blood
ventricular system - ANSWER-The cerebrospinal fluid-filled spaces inside the brain,
consisting of the lateral ventricles, third ventricle, cerebral aqueduct, and fourth
ventricle.
hydrocephalus - ANSWER-accumulation of fluid in the spaces of the brain
circumventricular organs - ANSWER-lacks a blood-brain barrier; can monitor
chemical changes in the blood
blood-brain barrier - ANSWER-Blood vessels (capillaries) that selectively let certain
substances enter the brain tissue and keep other substances out
pineal gland - ANSWER-seed of the soul
sagittal - ANSWER-A plane that divides the body into right and left portions.
axial - ANSWER-a horizontal slice of the brain cut from left to right, giving a view
from the top or bottom of the brain
coronal - ANSWER-front and back
nervous system - ANSWER-central nervous system and peripheral nervous system
central nervous system - ANSWER-brain and spinal cord
peripheral nervous system - ANSWER-everything lying outside the brain and spinal
cord
trigeminal nerve - ANSWER-starts out in the face, but the cell bodies are within the
skull, so it is part of CNS, not PNS
all neurons connects to and interact with other neurons - ANSWER-the connections
are functional, not actual connections
, The function of a neuron within the nervous system depends on - ANSWER-the
connections of that neuron
motor neurons - ANSWER-neurons that carry outgoing information from the brain
and spinal cord to the muscles and glands
sensory neurons - ANSWER-neurons that carry incoming information from the
sensory receptors to the brain and spinal cord
interneuron - ANSWER-a neuron that carries nerve impulses from one neuron to
another
Sensory dermatomes - ANSWER-area of skin supplied by a spinal nerve
shingles rash - ANSWER-affecting a thoracic dermatome.
sciatic nerve - ANSWER-largest nerve in the body
sciatica - ANSWER-Compressing the sciatic nerve produces a condition
sympathetic nervous system - ANSWER-directs activities for fight-or-flight responses
parasympathetic nervous system - ANSWER-directs activities for rest and
regeneration.
Dorsal root ganglion: - ANSWER-sensory cell bodies coming from periphery
Ventral root: - ANSWER-fibers leaving spinal cord to supply muscles
The Brain - ANSWER-Forebrain, Midbrain, & Hindbrain
The midbrain and hindbrain are collectively - ANSWER-Brainstem
The Brainstem - ANSWER-Medulla Oblongata and Pons Midbrain Most Cranial
Nerves Emerge from the Brainstem
vestibular system - ANSWER-balance
central pattern generators - ANSWER-neural mechanisms in the spinal cord that
generate rhythmic patterns of motor output (walking)
Damage to cerebellum interferes - ANSWER-coordinated movement to external
targets.
Cerebellum is also important - ANSWER-language, memory, attention, and emotion.
Midbrain - ANSWER-A small part of the brain above the pons that integrates sensory
information and relays it upward.
