Flashcards in Lecture 1 Deck (22):
What are the 4 parts of the CNS?
Assign dorsal/ventral for the brain and spinal cord.
Dorsal = top 1/2; ventral = bottom 1/2 (towards feet)
Dorsal = back; ventral = belly
What is the difference between para and midsagittal?
Midsagittal = sagittal cut down the mid-line
Parasagittal = all other sagittal cuts
What is a nerve cell body in the CNS vs PNS?
CNS = neuron
PNS = ganglion cell
What is a collection of neuron cell bodies in the CNS vs PNS?
CNS = nucleus
PNS = ganglion
What is a bundle of nerve fibers in the CNS vs PNS?
CNS = tract
PNS = nerve
What is a fasciculus? Vs funiculus?
FAS = A bundle
FUN = cord
What is a lemniscus?
What is a commisure? And a decussation?
COM = bundle fibers crossing the mid-line
DEC = point where tract cross the mid-line
What is ipsilateral vs contralateral?
IPS = same side of the midline
CONTRA = opposite side of the midline
What is afferent vs efferent?
Afferet = into a structure
Efferent = away from
What are the 4 structures that make up the lateral ventricle?
What are the 4 lobes of the brain?
Which 3 sulci define the boundaries of the lobes of the brain?
Central sulcus (pre and post central)
What 2 structures lie within the sylvian fissure?
Insula = hidden gyri
Where is white and gray matter in the brain vs spinal cord?
White = inside & gray = outside
Spinal cord is opposite
Where is the primary motor cortex?
Where is the primary somato-sensory cortex?
Where is the primary auditory cortex?
Temporal lobe - Sylvian fissue
Where is the primary visual cortex?
What kind of cortex makes up the bulk of cerebral hemispheres?
Association - coordinates both sides of the brain
