Exam Questions and CORRECT Answers
dura mater - CORRECT ANSWER - outermost layer of the meninges
very thick, tough, leathery
adheres to the skull
arachnoid mater - CORRECT ANSWER - the middle layer
thin and web-like, shiny
pia mater - CORRECT ANSWER - inner most layer
in direct contact with the brain
small; very thin and fragile
adheres directly to the brain
frontal/coronal planes - CORRECT ANSWER - divides into front and back
sagittal plane - CORRECT ANSWER - divides into left and right
horizontal plane - CORRECT ANSWER - parallel to the dorsal/ventral axis
sulci - CORRECT ANSWER - grooves on the surface of the brain
,very large one = fissure
gyri - CORRECT ANSWER - raised bumps on the surface of the brain
frontal lobe - CORRECT ANSWER - most caudal portion contains the primary motor
cortex (necessary to plan and execute coordinated movements of the body)
bound by the ansate sulcus and pseudosylvian sulcus
parietal lobe - CORRECT ANSWER - contains the primary somatosensory cortex
(necessary for sensory feelings of the body)
bound by the ansate sulcus, suprasylvian sulcus, and lateral sulcus
temporal lobe - CORRECT ANSWER - found on the side of the brain, contains the
auditory cortex
bound by the pseudosylvian sulcus and the suprasylvian sulcus
occipital lobe - CORRECT ANSWER - contains the visual cortex
medial to the lateral sulcus
central sulcus - CORRECT ANSWER - divides the frontal lobe from the more caudal
parietal lobe
homunculus - CORRECT ANSWER - contains primary motor cortex and primary
somatosensory cortex
, shows how the body is mapped onto the surface of the cortex
brainstem - CORRECT ANSWER - medulla, pons, and midbrain
midbrain - CORRECT ANSWER - most rostral portion of the brainstem
tectum - "roof"; made up of superior and inferior colliculi
tegmentum - "floor"; contains collections of cell bodies (nuclei) that function in sleep/wake
cycles, arousal, and temperature regulation
pons - CORRECT ANSWER - "bridge"; found caudal to the midbrain
contains both white and gray matter
nuclei are involved with a number of body functions, such as respiration, sleep, swallowing,
vomiting, posture, and others
contains many white matter fiber tracts that communicate information between the cerebral
hemispheres and the cerebellum and medulla
contains tracts that carry the body's sensory signals to the thalamus, and from the thalamus to the
body
medulla oblongata - CORRECT ANSWER - caudal to the pons
connects directly with the spinal cord
