Q

parietal lobe function

A

sensation

19
Q

two cortexes found in the parietal lobe

A
  • motor
  • somatosensory
20
Q

motor cortex function

A

controls movements

21
Q

somatosensory cortex function

A

sensations (hot and cold)

22
Q

occipital lobe function

A

vision

23
Q

Where is amyloid located?

A

in the cell membrane

24
Q

When does amyloid become beta-amyloid?

A

when it detaches from the cell membrane

25
Q

How is beta-amyloid cleared?

A
  • diffusion into blood vessels
  • microglia absorb B-amy and destroy it
26
Q

The sympathetic nervous system is responsible for

A

Fight or flight (gets you moving)

27
Q

The parasympathetic nervous system is responsible for

A

relax and digest

28
Q

Components of PNS

A

nerves that connect the brain or spinal cord to glands, muscle and sense organs

29
Q

ganglion definition

A

Bumps that contain cell bodies

30
Q

what is lateral inhibition?

A

excited neuron reduces the activity of its neighbors (this disables the spreading of action potentials)

31
Q

Phasic receptors

A

only activate when exposed to stimuli

32
Q

Tonic receptors

A

Stimuli increase frequency, receptors are always on

33
Q

Sensory pathway steps

A
  1. Stimuli Sensing
  2. Action potential
  3. Propagation
34
Q

Receptor type depends on

A

the type of stimuli

35
Q

During propagation, the spinal cord brings the signal to the

A

opposite side of the touch was received

36
Q

analgesia definition

A

same neurons secrete inhibitory morphine-like endogenous opioids to regulate pain

37
Q

Types of receptors (somatic sensation)

A
  1. free receptors (free nerve endings)
  2. encapsulated receptors
38
Q

Merkel cells

A

capture touch, shape, and texture

39
Q

Meissner cells

A

touch, pressure, and vibration

40
Q

Raffini Corpuscle senses

A

Deep pressure and vibration

41
Q

Pacinni cells sense

A

Deep pressure and vibrations

42
Q

Phasic-type cells within somatic sensation

A

Pacini and Meissner cells

43
Q

Tonic cells within somatic sensation

A

Ruffini and Merkel cells
