22
Q

What does the lateral sulci separate?

A

Frontal from temporal

23
Q

What does the parieto-occipital separate?

A

Parietal and occipital

24
Q

What does the longitudinal cerebral separate?

A

two hemispheres

25
Q

What are the 6 major hormones produced by the anterior lobe pituitary functions?

A

Growth hormone, thyroid stimulating hormone, adrenocorticotrophic hormone, follicular stimulating hormone, luteninizing hormone, prolactin

26
Q

What are the hormones produced by the 2 posterior lobes?

A

-vasopressin and oxytocin

27
Q

What are the brainstem?

A

Midbrain, pons, medulla

28
Q

What is the function of the midbrian?

A

body and eye movement, vision and hearing integration

29
Q

What is the function of the pons?

A

Motor control, sensory interpretation (sleep and consciousness)

30
Q

What is the function of the medulla?

A

-Autonomic body functions including breathing, heart rate

31
Q

What is the function of the cerebellar functions?

A

-Coordination of movement, posture and balance

32
Q

What is the arbor vitae?

A

Is the cerebellar white matter, so called for its branched, tree-like appearance. I

33
Q

What is the cingulate gyri?

A

Limbic-emotion and pain

34
Q

Where is the corpus callosum?

A

relay station/connect two hemispheres

35
Q

Where is the septum pellucidum?

A

Separates lateral ventricles

36
Q

What is the conus medularis?

A

End of spinal cord

37
Q

What is the caudal equine?

A

2nd-5th lumbar out of conus medularis

38
Q

What is the white/grey mater layout of the spinal cord?

A

Grey is inside and white is outside

39
Q

What are the ventral roots?

A

motor

40
Q

What are the dorsal roots?

A

sensory

41
Q

What makes up the dorsal root ganglion?

A

somas

42
Q

What is the Denticulate ligament?

A

pia mater of the spinal cord extensions, 21 per side, helps prevent side to side movement

43
Q

What is the Filum terminale?

A

is a delicate strand of fibrous tissue, about 20 cm in length, proceeding downward from the apex of the conus medullaris.It is one of the modifications of pia mater. It gives longitudinal support to the spinal cord

44
Q

What is the Falx cerebri?

A

So named from its sickle-like form, is a strong, arched fold of dura mater that descends vertically in the longitudinal fissure between the cerebral hemispheres.

45
Q

What is the Falx cerebelli?

A

is a small sickle shaped fold of dura mater, projecting forwards into the posterior cerebellar notch as well as projecting into the vallecula of the cerebellum between the two cerebellar hemispheres

46
Q

What is the tentorium cerebelli?

A

An extension of the dura mater that separates the cerebellum from the inferior portion of the occipital lobes.

47
Q

What is the diaphragma sellae?

A

or sellar diaphragm is a flat piece of dura mater (with a circular hole allowing the vertical passage of the pituitary stalk). It retains the pituitary gland beneath it in the fossa hypophyseos as it almost completely roofs the fossa hypophyseos of the sella turcica, a part of the sphenoid bone.`

48
Q

What is the arachnoid granulations?

A

Are small protrusions of the arachnoid (the thin second layer covering the brain) through the dura mater (the thick outer layer).

49
Q

What is Subarachnoid space?

A

The space between the arachnoid and the pia mater through which the cerebrospinal fluid circulates and across which extend delicate trabeculae of connective tissue.

50
Q

What is the flow of CSF?

A

produced from within the two lateral ventricles. From here, the CSF passes through the Interventricular foramina (of Monro) to the third ventricle, then the cerebral aqueduct (of Sylvius) to the fourth ventricle. The fourth ventricle is an outpouching on the posterior part of the brainstem. From the fourth ventricle, the fluid passes through three foramen to enter the subarachnoid space. It passes through the Foramen of Magendie on the midline, and two Foramen of Luschka laterally. The subarachnoid space covers the brain and spinal cord.[1]

51
Q

Where is CSF produced?

A

choroid plexus

52
Q

Where is CSF reabsorbed?

A

Returns to the vascular system by entering the dural venous sinuses via the arachnoid granulations (or villi).
