Forebrain and receptors Flashcards
Epithalamus
pineal gland
secrets melatonin which appears to regulate the bodies inner clock
Epithalamus
choroid plexus
a network of capillaries. One of the primary functions is to produce cerebrospinal fluid (CSF) via the ependymal cells that line the ventricles of the brain.
Thalamus
Thalamus
2 oval masses centrally located in the center of the brain
Thalamus
what is the major function of the thalamus?
relay point and processing center for all sensory impulses going to the cerebral cortex
expect for smell
telencephalon (cerebrum)
describe the telecephalon
gray matter?
consists of an outer gray matter, cerbral cortex; and inner white matter (contains myleainted axons)
telencephalon (cerebrum)
raised/elevation
gyrus
telencephalon (cerebrum)
shallow groove
sulcus
telecephalon (cerebrum)
deep groove
fissure
Lobes (frontal)
what is the frontal lobe seperated from?
seprerated from parietal lobe by central sulcus
Lobes (frontal)
What does the frontal lobe contain?
(MSA, PMC)
1) motor speech area
2) primary motor cortex
Lobes (frontal)
motor speech area
controls the skelatal muscle movements necessary for vocalization (speech)
Lobes (frontal)
primary motor cortex
located in the precentral gyrus and controls the direction of movement
lobes (parietal)
where does the parital lobe end?
ends anteriorly at the central sulcus; lateral limit at the lateral sulcus; posterior limit at the parietaoccipitus
lobes (parietal)
what does the parietal lobe contain?
(PSSC, WA)
1) primary somatosensory cortex
2) wernicke’s area
lobes (parietal)
primary somatosensory cortex
recieves info from the skin, pain, pressure, temp, and touch + texture and shape. It is located in the past central gyrus of each parital lobe
