last a and p exam

CNS white and gray matter (brain)

gray matter is outer cortex, as well as inner neclei

white matter is deep

gray and white matter which is myelinated and which isnt

gray is unmyelinated

white is myelinated

is the spinal cord different for w and g matter

yes in the spinal cord white matter is on the outer layer gray is deeper

what is the frontal lobe function

JEMM motor speech

what is the parietal lobe function

sensory

somatic sensations

visual process

taste

whats occipital lobe

visual awareness and processing

whats temporal lobe function

hearing

smell

learning

precentral gyrus

primary motor cortex

postcentral gyrus

sensory

what is the basal nuclei for

motor function control

caudate nucleus

putamen

globus pallidus

masses of gray matter in nucleus

what are projection tracts

vertically through the brain to spinal cord

what is commissural tracts

cross from one hemisphere to the other

association tracts

connects lobes and gyri of each hemisphere to eachother

what is the amygdala important for

emotions and hippocampus in memory

what is the limbic system for

influences emotions, innate responses to emotions, motivation, mood, sensations of pain and pleasure

basic survival

what does the diencephalon do

receives almost all sensory info on its way to cerebral cortex, DIRECTS INFO TO APPROPRIATE AREA

role in motor control, relaying signals from cerebellum to cerebrum

what does the cerebellum do

control in balance, posture, fine motor control

(comparing textures of objects)

what does the medulla oblongata do

all in and out fibers connecting brain and spinal cord through

REGULATES HR, blood vessel diameter, respiration, breathing, swallowing

what does pons do

sleep, respiration, hearing balance, taste, CN 5, 6, 7, 8

what does mid brain do

central aqueduct

CN 3 and 4

what does substantia nigra do

sends inhibitory signals to basal ganglia and thalmas

what does hypothalamas control

homeostasis

autonomic ns

bod temp and feeding

sleep

what is wernicke’s area

sensory understanding spoken and written language

what does brocas area do

motor speech production forming words

where and what are meninges

layers on the brain

Dura matter

arachnoid mater

pia mater
