20
Q

Valleys

A

Sulci

21
Q

What is the cycle path for cerebrospinal fluid

A

Lateral ventricles>interventricular foramina>third ventricle> cerebral aqueduct> fourth ventricle>central canal>choroid plexuses

22
Q

Three layers of meninges

A

Dura mater (outer), arachnoid mater (middle), pia mater (inner)

23
Q

Where the dura mater becomes a pillowcase and divides to allow passage of deoxygenated blood away from the brain

A

Dural venous sinuses

24
Q

Where is the CSF produced

A

choroid plexus of the lateral ventricles

25
Q

The third ventricle is surrounded by the…

A

thalamus

26
Q

The fourth ventricle is surrounded by the…

A

Pons anteriorly and cerebellum posteriorly

27
Q

These structures take CSF into the blood vessels surrounding the brain

A

arachnoid aranulations

28
Q

Initiaties movement and coordinate antagonistic muscle pairs; found deep within the cerebral hemispheres bear ventricles; grey matter

A

Basal Nuclei

29
Q

Connects the right and left sides of the brain; corpus callosum

A

Commissural tracts

30
Q

Connects higher and lower regions of the central nervous system;

A

Projection tracts

31
Q

Generally found in the cerebrum, connect one part of the cortex to adjacent regions of the same hemisphere

A

Association tracts

32
Q

Relay station

A

Thalamus

33
Q

Provides autonomic control, produces emotions, regulates sleep cycle and regulates body temperature; includes pituitary gland

A

Hypothalamus

34
Q

White matter tracts that travel to and from the cerebral hemispheres in the midbrain

A

Cerebral peduncles

35
Q

nuclei (grey matter) in the midbrain that includes the inferior and superior colliculi

A

Corpora Quadrigemina

36
Q

Visual reflex center in midbrain

A

Superior colliculi

37
Q

Auditory reflex center in the midbrain

A

Inferior colliculi

38
Q

A passageway for neuron that contains mostly white matter (in brainstem)

A

Pons

39
Q

White matter tracts that travel towards the cerebellum

A

Cerebellar peduncle

40
Q

Cardiovascular control, respiratory control, other visceral reflexes (GI Tract)

A

Medulla oblongata

41
Q

Located on the anterior surface of the medulla and contains corticospinal tracts (descending axons going to spinal cord)

A

Medullary pyramids

42
Q

controls balance and proprioception; little brain

A

cerebellum

43
Q

Connects the two hemispheres of the cerebellum

A

vermis

44
Q

white matter on the cerebellum

A

arbor vitae

45
Q

Ridges along the lobe of the cerebellum

A

Folia

46
Q

Includes cerebral cortex, thalamus, hypothalamus. Structures coordinate to recognize social cues and elicits emotions and memory

A

Limbic system

47
Q

Group of nuclei in brainstem that are responsible for filtering/limiting sensory info from reaching your conscious mind and keeps you alert

A

Reticular formation
