Q

What are Otolith? (2)

A

a main organ in the vestibular system

Provides messages about our 3D space sensitive to speed and direction

17
Q

What is the semicircular canals?

A

A main organ in the vestibular system

3 canals filled with endolymph and hair cells

18
Q

What is nocieption?

A

Receptors sensitive to pain and temperature

19
Q

What does encapsulated mean?

A

Surrounded by capsules

20
Q

What does unencapsulated mean?

A

surrounded by nerve endings

21
Q

What are free nerve endings?

A

Dendrites that aren’t attached to anything become attached to sensory neurons

22
Q

What is two-point discrimination?

A

The ability to know that 2 points touching the skin are 2 distinct objects touching the skin rather than just 1

23
Q

What is homunuculus?

A

the sensory map

24
Q

What is the spinothalamic surgery?

A

Nociceptive and crude touch information ascends contralaterally

25
Q

What is the dorsal column pathway?

A

Where touch information ascends the spinal cord this way

26
Q

What is the epidermis?

A

Top layer of the skin that produces cells that pigment the skin and protect the immune system

27
Q

what is the dermis?

A

Layer of the skin that contains much of the nerve endings, oil, sweat glands and hair follicles

28
Q

What is glabrous skin?

A

Hairless skin
