Q

what is the choroid plexus of 4th ventricle

A

contains lateral aperture for CSF release into subarachnoid

23
Q

lateral olfactory tract travels to

A

piriform lobe

24
Q

optic chiasma is right at transition of

A

PNS into CNS

25
Q

If PLR works, the lesion is where?

A

caudal to the chiasm

26
Q

review PLR

A

X

27
Q

Mamillary bodies function in

A

autonomic involluntary control

28
Q

where are crus cerebri located

A

in mesencephalon

29
Q

what is the only nerve to arise from the dorsal brain stem

A

cn IV

30
Q

Transverse pontine fibers ascend into

A

middle cerebellar peduncle

31
Q

transverse pontine fiber function

A

transmits UMN info from cell bodies of frontal lobe into the cerebellum (most fibers are for skilled motor control)

32
Q

unconcsious proprioception tracts go to

A

cerebellum

33
Q

what are the pyramids

A

umn tract form cell bodies of frontal lobe

34
Q

approximate junction of MO and spinal cord

A

can only be determined histologically

35
Q

what cranial nerves live on ventral aspect; in more midline than other nerves

A

III, VI, XII

36
Q

Ventricular system consists of

A

lateral ventricles, 3rd ventricle, mesencephalic aqueduct, 4th ventricle

37
Q

where is the 3rd ventricle located

A

diencephalon

38
Q

where is the 4th ventricle

A

metencephalon and myelencephalon

39
Q

what are the common obstruction sites of the ventricular system

A

inteventricular foramina
mesencephalon
lateral aperture

40
Q

what is the function of the choroid plexus

A

produces CSF (production is not pressure dependent, so will not stop productione ven if there is an obstruction)

41
Q

what is teh corpus callosum

A

white mattter axons transversely oriented that communicate with right an left brain

42
Q

what is the fornix function

A

talk to mamillary bodies; part of the lymbi system; major behavior area

43
Q

what is the septum pellucidum

A

paper thin membane that separates right ventricle from left ventricle

44
Q

cingulate gyrus functions in

A

behavior (the target of furious rabies)

45
Q

callosal sulcus functions in

A

separating the corpus callosum from the angulate gyrus

46
Q

subcallosal area

A

neurons sweep to mamillary bodies

47
Q

rostral lobe of cerebeluum

A

motor control of the trunk muscle

48
Q

caudal lobe of cerebellum

A

controlling muscle activity of distal appendages

49
Q

medulla of cerebellum

A

white matter (axons); aslo called arbor vita

50
Q

pineal gland

A

produces melatonin in darkness; sleep/wake pattern; photoperiod function (can be different shapes in different brains); just know it is a normal structure

51
Q

interthalamic adhesion

A

sensory relay for all conscious sensory modality; all conscious modalities synapse in thalamus

52
Q

caudal commissure

A

cross over of pretectal neurons for PLR
