diencephalon
brainstem - ANSWER-mid brain, pons, medulla oblongata
the spinal cord is part of the ___________ nervous system - ANSWER-central
the brain is part of the ___________ nervous system - ANSWER-central
the cranial nerves are part of the _____________ nervous system - ANSWER-
peripheral
the central sulcus separates the __________ and _________ lobes - ANSWER-frontal,
parietal
the lateral sulcus arks the boundary between the ________ and ________ lobes -
ANSWER-frontal, temporal
the convulsions on the surface of the brain are called - ANSWER-gyri
a neuron may or may not contain myelin sheath (T or F) - ANSWER-true
fibers connecting two regions within the same cerebral hemisphere are called -
ANSWER-association
microglial cells - ANSWER-devour damaged nuerons
the pre central gyrus is located in the - ANSWER-frontal lobe
language abilities are dominant in the _______ hemisphere for most individuals -
ANSWER-left
label the lobes of the brain - ANSWER-
sulcus of the brain - ANSWER-
, central sulcus - ANSWER-separates pre central gyrus and post central gyrus
white matter - ANSWER-axonal bundles in the nervous system. myelin sheath
bundles give it the white color

association fibers - ANSWER-interconnect various cortical regions in the same
hemisphere (frontal lobe has to talk to the temporal lobe)
gray matter - ANSWER-group of nerve cell bodies
cerebral cortex - ANSWER-dark regions or gray matter at the surface of the brain
subcortical nuclei - ANSWER-basal ganglia, claustrum, amygdaloid nucleus
gray matter is the term - ANSWER-is the term used for the collection of cell bodies in
the central nervous system
meninges - ANSWER-duramater, arachnoid, piamater. membranes covering the brain
and spinal cord
duramater - ANSWER-toughest and strongest membrane. created under abnormal
conditions
arachnoid - ANSWER-mesh/web like appearance.
subarachnoid - ANSWER-cerebrospinal fluid envelopes brain and spinal cord
piamater - ANSWER-closely attached to the brain, thin, and delicate
epidural - ANSWER-typically around the spinal cord unless an abnormality is present
such as bleeding then it is found on the brain
ventricular system - ANSWER-
4th ventricle - ANSWER-communicates with subarachnoid space
CSF - ANSWER-cerebralspinal fluid which circulates around subarachnoid
