32
Q

what is the function of the medulla oblongata

A

respiratory and cardiovascular control

reflexes involving coughing vomiting and sneezing

33
Q

what is the function of the pons

A

relays info to the diencephalon and cerebellum

respiratory centers to aid the medulla oblongata

34
Q

what are the 3 major parts of the brain stem

A
  • medulla oblongata
  • pons
  • midbrain
35
Q

what does the midbrain do

A

contains sensory and motor tracts

A
  • superior colliculi

- inferior colliculu

37
Q

where is the corpora quadrigemina located

A

the midbrain

38
Q

what does the superior colliculi do

A

reflex centers involved in visual stimuli resulting in eye, head, and neck movements

39
Q

what does the inferior colliculi do

A

reflex centers involved in auditory stimuli resulting in head and trunk movements

40
Q

what does the cerebellum do

A

smooths and coordinates contractions of sleet muscles. regulates posture and balance

41
Q

what are the 2 cerebral hemispheres joined by

A

vermis

42
Q

what are the gray matter “folds” in the cerebellar cortex called

A

folia

43
Q

what are arbor vitae

A

tracts of white matter

44
Q

what are the 3 specific regions of the diencephalon

A
  • thalamus
  • hypothalamus
  • epithalamus
45
Q

what does the intermediate mass do

A

connects the 2 halves of the thalamus together

46
Q

what does the thalamus do

A

relays almost all sensory input to the cerebral cortex, contributes to motor functions
plays a role in maintenance of consciousness, emotions,learning, and memory

47
Q

what does the hypothalamus do

A

controls and integrates activities of ANS
-produces hormones, emotional and behavioral patterns, regulates eating, drinking and circadian rhythms, controls body temp

Q

what does the infundibulum do

A

connects hypothalamus to pituitary gland

Q

what does the epithalamus do

A

contains the pineal gland which secretes melatonin

gray matter=

A

cell bodies and dendrites

61
Q

nucleus=

A

CNS cluster of neuron cell bodies

62
Q

what does the cerebral cortex do

A
  • integrates sensory information
  • initiates motor output
  • involved in emotions and intellectual processes
63
Q

where is basal nuclei located and what is it

A

cerebral gray matter composed of paired nuclei deep within each cerebral hemisphere

64
Q

what do basal nuclei do

A
  • help initiate and terminate movements, suppress unwanted movements, and regulate muscle tone
  • limbic system promotes range of emotions, including pleasure, pain, docility, affection, fear and anger
65
Q

what are the 2 types of functional areas of the cerebrum

A

primary and association

66
Q

what does the primary functional area of the cerebrum do

A

-directly receives or sends signals

67
Q

what does the association functional area of the cerebrum do

A

-perform complex integrative functions

68
Q

what does CSF do

A

filtered blood plasma that bathes brain and spinal cord providing nutrients

69
Q

what does the choroid plexus do

A

networks of blood capillaries in the walls of the ventricles that filter the blood plasma into ependymal cells

70
