1

Where are chemoreceptors?

On your tongue and in your nose

2

Photoreceptors

The receptors that are active if a photon of light reach it in the retina

3

Mechanoreceptors

Responds to movement of the skin

4

Thermoreceptors

Responds to temperature and specific degrees

5

Nociceptors

Pain receptors; stimulated by tissue damage

6

Somatosensation

Touch, proprioception, pain, and thermal sensation

7

Dorsal column medial lemmiscal pathway

Mediates touch and proprioception; enters the dorsal root ganglion

8

Pacinian corpuscles

High-frequency vibrations on the skin

9

Meissner's corpuscles

Adapt rapidly to touch; why you don't detect your clothes after short period of time

10

What allows you to type pain?

Free nerve endings

11

Dermatome

An area of the skin supplied by nerves from a single spinal root

12

Receptive field

Amount of skin that sends info to a single neuron

13

Shingles

Leaves lesions in the dermatome; damages the dorsal root ganglion

14

Is all sensory information perceived?

No
