Neuroanatomy Flashcards
(89 cards)
Ramon y Cajal
investigated that neurons are not physically connected, won the Nobel Prize
Meninges
protective sheaths around the brain
Sulci
grooves/spaces
Gyri
neural folds of tissue
Coronal plane
divides dorsal/ventral (belly/back)
Horizontal plane
Dividing rostral/caudal (top and bottom)
Rostral
toward the beak (front)
Caudal
toward the tail (back)
sagittal
dividing left-right
ventral
front
dorsal
back
dura mater
outer layer of meninges, hard,
arachnoid mater
middle layer of meninges, soft, spongy, web-like
pia mater
smaller surface blood vessels of brain and spinal cord
subarachnoid space
between pia and arachnoid, full of CSF
cerebrospinal fluid (CSF)
bathes and floats brain in skull
frontal lobe
(in the front) executive function, motor function, problem solving, memory, language, initiation, judgment, impulse control
parietal lobe
caudal to frontal lobe, dorsal to temporal lobe
- processing sensory information, interpreting visual information, processing language, mathematics, orientation of body to space
temporal lobe
ventral to frontal and parietal lobes
- auditory processing and perception, structural memory, visual processing
- comprehension of speech, integration of patterns of stimuli
occipital lobe
back of the brain, caudal to parietal and temporal lobes
-visual processing
lateral (Sylvian fissure)
separates temporal from parietal lobe)
central (Rolandic fissure)
separates parietal lobe from frontal lobe
falx cerebri
made of dura mater, divides cerebral hemisphere, provides cushion and cradles cerebrum
cerebellum
“little brain” covered by cerebellar cortex
important to motor system, coordination, balance, speech, posture
