Q

What is the inferior colliculi?

A

An auditory reflex, helps to process sound

24
Q

Where is the pons located?

A

Between the medulla oblongata and the midbrain
- In front of the fourth ventricle and the cerebellum
- Connected to the cerebellum through horizontal fibers

25
Q

What do the pyramids in the medulla do?

A

Axons within the pyramids control voluntary movement

26
Q

Where is the medulla?

A

The bottom of the brainstrem
- Continuous with spinal cord

27
Q

What does the medulla regulate?

A
  • Rate and depth of breathing
  • Blood pressure
  • Vomitting, hiccupping, swallowing, coughing, sneezing
28
Q

What is the cerebellum made up from?

A
  • Two hemispheres
  • A vermis that separates them
  • The cerebellar peduncles
29
Q

What is the function of the cerebellum

A
  • Helps in coordinating physical movements
30
Q

What makes up the meninges?

A

1) The dura mater
2) The arachoid mater
3) The pia mater
4) The dural sinuses (venous sinuses)

31
Q

What is the role of the meninges?

A

To protect the brain and spinal cord

32
Q

Describe the structure of the Dura mater

A
  • Outermost layer of meninges
  • Thickest and toughest layer within skull
  • Consists of two sublayers glued together
33
Q

What is the outermost (closest to skull) layer of the dura mater called?

A

The periosteal layer

34
Q

What is the innermost (closest to brain) layer of the dura mater called?

A

The meningeal layer

35
Q

What does the falx cerebri do?

A

Separates the two hemispheres of the cerebrum

36
Q

What does the falx cerebelli do?

A

Separates the two hemispheres of the cerebellum

37
Q

What does the tentorium cerebelli do?

A

Separates the cerebrum from the cerebellum

38
Q

The falx cerebri, falx cerebelli, and tentorium cerebelli are all structures of what connective tissue membrane?

A

The dura mater

39
Q

What are the dural sinuses?

A

Spaces formed by separation of the dural layers
- Some collect blood from brain

40
Q

What is the arachnoid mater?

A
  • Loose covering of the brain and spinal cord
41
Q

What is the subarachnoid space?

A

A space filled with cerebral spinal fluid that contains blood vessels
- Space between brain and maters
- Collagen fibers connect brain to pia mater in this space in a meshwork-type structure

42
Q

What is the pia mater?

A

Innermost layer of the meninges
- Clings tightly to brain

43
Q

What is the ventricular system?

A

4 cavities (ventricles) and their connecting channels
All connected to each other through central canal

44
Q

Describle the lateral ventricals

A
  • Large, backwards c-shaped chambers
  • Located deep within cerebral hemishphere
  • Named components are related to where those components are found in the brain
  • Each lateral ventricle opens up and drains into the third ventricle via two passageways called the interventricular foramen
45
Q

The anterior horn of the lateral ventricle has parts in which lobe?

A

The frontal lobe

46
Q

The posterior horn of the lateral ventricle has parts in which lobe?

A

The occipital lobe

47
Q

The Interior horn of the lateral ventricle has components in which lobe?

A

The temporal lobe

48
Q

The body of the lateral ventricle has components in which lobe(s)?

A

The frontal lobe and the parietal lobe

49
Q

Describe the third ventricle

A
  • Narrow slit-like cavity between the two halves of the thalamus
  • Opens into and connects to the fourth ventricle by the cerebral aquiduct, which passes through the midbrain
50
Q

Describe the fourth ventricle

A
  • Located behind the pons, but in front of the cerebellum
  • continous with central canal of spinal cord
  • Opens up into subarachnoid space
51
Q

What is the choroid plexus?

A

Found in 3rd and 4th ventricle and makes cerebral spinal fluid

52
Q

The internal carotid arteries enter through….

A

the skull through the carotid canal

53
Q

The vertebral arteries enter the skull through the…

A

froamen magnum

54
Q

What is the basilar artery

A

The joining of the vertebral artieries
.- The basilar artery ends by dividing into the posterior cerebral arteries

55
Q

How do the internal carotid artieres end?

A

They divide and give rise to the anterior and middle cerebral arteries

56
Q

What is the circle of willis?

A
  • A circle of blood vessels creates by the anterior cerebral arteries
  • Involves the posterior cerebral arteries, the posterior communicating artery, the internal carotid arteries, the anterior cerebral arteries, and the anterior communicating artery
