ANSWERS
primary motor cortex - Answer-plan movements and send motor signals to the spinal
cord
corpus callosum - Answer-where axons cross between hemispheres
frontal lobe - Answer-motor control and executive functions
parietal lobe - Answer-somatosensory/tactile processing
temporal lobe - Answer-auditory processing, language, memory
occipital lobe - Answer-visual processing
cerebellum - Answer-motor planning, motor learning, balance
diencephalon - Answer-thalamus and hypothalamus
thalamus - Answer-relay for information going to and from the cerebrum

feeding, sexual behavior, sleeping, temperature regulation, autonomic nervous
system, etc
tectum - Answer-sensory tectum/tegmentum
superior colliculus - Answer-visual colliculus
inferior colliculus - Answer-auditory colliculus
tegmentum - Answer-motor tectum/tegmentum
ventral tegmental area - Answer-reward area
substantia nigra - Answer-initiating movements area
pons - Answer-includes axons that allow the cerebellum to communicate with the
brainstem and the cerebral cortex
medulla - Answer-coordinates basic life functions and reflexes (breathing, heart rate,
vomiting, salivation, coughing, sneezing)
dura mater - Answer-thick, outermost layer of the meninges
, arachnoid mater - Answer-middle layer of the meninges
pia mater - Answer-thin, delicate inner membrane of the meninges
cranial nerves - Answer-12 pairs of nerves that carry messages to and from the brain
cerebral cortex - Answer-The intricate fabric of interconnected neural cells covering
the cerebral hemispheres; the body's ultimate control and information-processing
center.
gyrus - Answer-ridge/bump
sulcus - Answer-groove/crack
fissure - Answer-infolding of sulci and gyri
central sulcus - Answer-separates parietal and frontal lobes
sylvian fissure - Answer-separates the temporal lobe from those surrounding it
longitudinal fissure - Answer-separates the two hemispheres
postcentral gyrus - Answer-directly behind the central sulcus; contains the primary
somatosensory cortex
primary somatosensory cortex - Answer-processes touch and pain information
precentral gyrus - Answer-directly in front of the central sulcus; contains the primary
motor cortex
rostro-caudal - Answer-front of brain to back of brain
dorso-ventral - Answer-back of brain stem to front of brain stem
anterior-posterior - Answer-front of head to back of head
superior-inferior - Answer-top of head to bottom of head
proximal/medial - Answer-closer to the midline of the body
distal/lateral - Answer-further from the midline of the body
reticular theory - Answer-nerves communicate through a continuous nerve net
neuron doctrine - Answer-nerves are discrete individual cells
dendrites - Answer-receive input from other neurons and carry messages towards
the cell body; usually many per neuron
soma - Answer-contains the nucleus and machinery to maintain life
