Neuroanatomy Exam Questions And 100% CorrectAnswers A+ Graded

Pons - ANSWER A hindbrain structure that relays information from the cerebellum to the
rest of the brain
Midbrain - ANSWER The small part of the brain above the pons that integrates sensory
information and relays it upward.
Cerebellum - ANSWER the "little brain" at the rear of the brainstem; processes sensory
input and coordinates movement output and balance
vermis - ANSWER Connects the two hemispheres of the cerebellum
Meninges - ANSWER three protective membranes that surround the brain and spinal
cord
frontal lobe - ANSWER The lobe at the front of the brain associated with movement,
speech, and impulsive behavior.
parietal lobe - ANSWER portion of the cerebral cortex lying at the top of the head and
toward the rear; receives sensory input for touch and body position
temporal lobe - ANSWER An area on each hemisphere of the cerebral cortex near the
temples that is the primary receiving area for auditory information
, occipital lobe - ANSWER A region of the cerebral cortex that processes visual
information
lateral ventricles - ANSWER A pair of ventricles within the cerebral hemispheres.
Thalamus - ANSWER the sensory relay station of the brain, sits atop the brainstem; it

hemispheres and carrying messages between them
spinal nerves - ANSWER carry impulses to and from the spinal cord
central sulcus - ANSWER separates frontal and parietal lobes
precentral gyrus - ANSWER the strip of frontal cortex, just in front of the central sulcus,
that is crucial for motor control
postcentral gyrus - ANSWER the strip of parietal cortex, just behind the central sulcus,
that receives somatosensory information from the entire body
lateral fissure - ANSWER separates temporal lobe from frontal and parietal lobes
medial longitudinal fissure - ANSWER Deep groove separating the left and right halves
of the cerebrum
Parahyppocampal gyrus - ANSWER Grey matter cortical region of the brain that
surrounds the hippocampus and is part of the limbic system
cingulate gyrus-ANSWER a strip of limbic cortex lying along the lateral walls of the
groove separating the cerebral hemispheres, just above the corpus callosum
optic chiasm-ANSWER the point in the brain where the visual field information from each
eye "crosses over" to the appropriate side of the brain for processing
