Q

Internal Capsule

A

large white matter structure that contains both ascending and descending axons, to/from cerebral cortex and through the thalamus

23
Q

Optic Tracts

A

part of the visual system

the posterior continuation of the optic nerves after the medial (temporal lobe) fibers decussate at the optic chiasm

24
Q

Thalamus

A

deep brain structure, part of the diencephalon

sensory and motor signal relay to/from cortex

regulationso of consciousness and sleep

25
Q

Hypothalamus

A

together with the pituitary gland, they control other glands that produce hormonse in the body

regulates body temp, thirst, sleep/wake cycle, hunger, sexual behaviors, heart rate, blood pressure

26
Q

Hippocampus

A

spatial memory and navigation

27
Q

Third Ventricle

A

carries CSF

located directly in the midline diencephalon directly between the left and right thalamus

36
Q

Posterior Inferior Cerebellar artery (PICA)

A

supplies the posterior inferior portion of the cerebellum

37
Q

Anterior Inferior cerebellar artery (AICA)

A

arises from the middle of the basilar artery and supplies the anterior inferior portion of the cerebellum

38
Q

Basilar Artery

A

becomes 2 paired vessels:

superior cerebellar artery

posterior cerebral artery

39
Q

Superior Cerebellar artery

A

supplies superior portion of the cerebellum

40

42
Q

Blood Brain Barrier

(components)

A

endothelial cells - capillary wall

astrocyte end-feet - sheaths the capillary

pericytes - embedded in capillary basement membrane

tight junctions - allows passage of water, gas, lipid-soluble molecules

43
