21
Q

What is the function of vasopressin?

A

regulate kidney function (fluid intake and excretion) and controls blood pressure

22
Q

What kind of hormone is vasopressin?

A

anti diuretic hormone

23
Q

which gland helps us sleep by producing melatonin?

A

pineal gland

24
Q

what happens when melatonin production not happening at the right times of day?

A

Jet lag

25
Q

which gland plays a role in circadian rhythm (sleep-wake cycle and the body’s internal clock)

A

pineal gland

26
Q

____ are hormones and neurotransmitters that are involved in the body’s “fight or flight” response.

A

catecholamine

27
Q

what secretes catecholamine

A

the hypothalamus
When the hypothalamus perceives a threat or stressor, it activates the autonomic/sympathetic nervous system, which in turn stimulates the adrenal glands to release catecholamines into the bloodstream.

28
Q

what part of the brain is important in balancing, planning, and executing voluntary movement?

A

cerebellum

29
Q

what are the three diff parts of the cerebellum

A

vestibulo cerebellum
spino cerebellum
cerebro cerebellum

30
Q

which part of the cerebellum is important in maintaining balance and controlling eye movement

A

vestibulo cerebellum

31
Q

which part of the cerebellum is involved with the inner ear to maintain equilibrium

A

vestibulo cerebellum

32
Q

which part of the cerebellum covers precise fine voluntary movements

A

spino cerebellum

33
Q

how does the spino cerebellum cover precise fine voluntary movement?

A

*looks at the intention of the higher cortex

*looks at the performance of the peripheral muscles
corrects any deviation

34
Q

which part of the cerebellum enhances muscle tone and coordinates skilled voluntary movements?

A

spino cerebellum

35
Q

which part of the cerebellum deals with skilled motor movement

A

spino cerebellum

36
Q

what is the site of procedural memories (the site of what we do repetitively like a dancer )?

A

cerebro cerebellum

37
Q

which part of the cerebellum plays a role in planning and initiating voluntary activity by providing input to cortical motor areas?

A

cerebro cerebellum

38
Q

the cerebro cerebellum plays a role in planning and initiating voluntary activity by

A

providing input to cortical motor areas

39
Q

what is the most primitive region of the CNS and its the site of the origin for the 12 cranial nerves?

A

brain stem

40
Q

what controls life sustaining processing such as respiration, circulation and digestion

A

brain stem

41
Q

Most of the cranial nerves innervate the head and neck except which

A

I. Olfactory - sensory fiber
II. Optic - sensory fiber
III. Oculomotor - motor fiber
IV. Trochlear - motor fiber
V. Trigeminal - both fibers
VI. Abducens - motor fiber
VII. Facial - both
VIII. Vestibulocochlear - sensory fiber
IX. Glossopharyngeal - both fibers
X. Vagus - both fibers
XI. Accessory - motor fiber
XII. Hypoglossal - motor fiber.
