24
Q

anterior commissure

A

located just anterior to the thalamus.

It connects parts of the frontal and temporal lobes of the two hemispheres.

25
Q

cerebellum

A

this is on the ventral portion of the caudal brain

26
Q

vertebral arteries

A

merge along the brainstem to form the single basilar artery.

27
Q

basilar artery

A

travels along the ventral surface of the pons (part of the brainstem).

It gives off several branches to the cerebellum along its path.

28
Q

posterior cerebral arteries.

A

two arteries that branch off the basilar artery on the pons’ superior ventral surface

29
Q

internal carotid arteries

A
  • feed into the circle of willis

- divide into the anterior cerebral arteries and the middle cerebral arteries

30
Q

middle cerebral artery

A

dives into the lateral fissure

- branches off the internal carotid artery

31
Q

anterior cerebral artery

A

travels anteromedially to the median longitudinal fissure

- branches off the internal carotid artery

32
Q

posterior communicating arteries

A

small-diameter arteries that connect the posterior cerebral and internal carotid arteries

33
Q

anterior communicating artery

A

connects the two anterior cerebral arteries just before entering the median longitudinal fissure

34
Q

septum pellucidum

A

a thin membrane that separates the anterior part of the lateral ventricles from each other

35
Q

internal capsule

A

this is a white fiber that separates the caudate and the putamen

white matter pathway is just lateral to the caudate nucleus, between the caudate and the putamen

36
Q

anterior horn of the lateral ventricle.

A

larger anterior portion

37
Q

body of the lateral ventricle

A

the thinner portion, just posterior to the anterior horn.

38
Q

inferior horn of the lateral ventricle

A

portion in the temporal lobe

39
Q

posterior horn of the lateral ventricle

A

extends posteriorly.

40
Q

third ventricle

A

a thin midline space that separates the left and right thalami

-appears to have a hole in the middle of it. This is created by a midline thalamic structure called the massa intermedia, or interthalamic adhesion

41
Q

interthalamic adhesion

A

this connects the two thalami and passes through the third ventricle

42
Q

interventricular foramen (of Monro)

A

connects the lateral ventricle to the third ventricle

43
Q

cerebral aqueduct

A

connects the third ventricle to the fourth ventricle

44
Q

fourth ventricle

A

this lies between the pons and the medulla

45
Q

Corpus callosum

A

Can be observed as the thick structure connecting the two hemispheres just inferior to the median longitudinal fissure.

46
Q

insula

A

this is observed laterally but deep, buried within the depths of the Sylvian fissure. Its functions are not well understood, but it is thought to play a role in taste.

47
Q

Anterior commissure:

A

only visible for a few slices. It is observed connecting the hemispheres inferiorly.

48
Q

lateral ventricle

A

The anterior horn, body, and posterior horn appear in the center of each hemisphere anteriorly, in slices towards the middle, and posteriorly in the brain, respectively. The inferior horn can be seen next to the hippocampus in the temporal lobe, and it is typically relatively thin and flat in shape.

49
Q

Amygdala

A

Located in the anterior portion of the medial temporal lobe. It is involved in behavior and giving emotional meaning to sensory input and memory. This appears as a center of gray matter in this region.

50
Q

Hippocampus

A

can be observed just posterior to the amygdala in the medial temporal lobe.

the hippocampus appears curled next to the inferior horn of the lateral ventricle.

51
Q

Caudate nucleus

A

Located deep in the brain next to the lateral ventricle. It is larger anteriorly and smaller posteriorly and somewhat C-shaped in the sagittal plane.

52
Q

Globus pallidus and Putamen

A

These are located just lateral to the internal capsule.
The putamen is lateral and slightly superior to the smaller globus pallidus.
The globus pallidus has two parts, which might be visible in some images.

53
Q

thalamus

A

Consists of a collection of nuclei that sit medial and posterior to the basal ganglia structures.

54
Q

Hypothalamus

A

located just inferior to the thalamus

55
Q

cerebellum

A

a structure that is located at the back of the brain, underlying the occipital and temporal lobes of the cerebral cortex

56
Q

midbrain

A

only see the midbrain on the midsagittal view

57
Q

pons

A

found above the medulla and below the midbrain, and is anterior to the cerebellum

Q

medulla oblongata

A

lower half of the brainstem
