2

interoceptors

receive stimuli from inside the body (eg change in blood pressure)

3

chemoreceptors

respond to nearby chemicals (eg pain receptors)

4

photoreceptors

respond to light energy

5

mechanoreceptors

respond to mechanical

6

thermoreceptors

stimulated by temperature changes (in hypothalamus)

7

sensation step 1/4

receptors respond to stimuli

8

sensation step 2/4

nerve impulses travel to cerebral cortex

9

sensation step 3/4

brain interprets info

10

sensation step 4/4

sensation/conscious perception occurs

11

umami

meaty/savory taste

12

smell receptors

olfactory cell (modified neurons, specific)
- olfactory bulb connects w/limbic system (emotion + memory)

13

anterior chamber of the eye

between cornea and lens; aqueous humor fluid

14

posterior chamber

most of eye; vitreous humor behind lens

15

sclera

white/fibrous part of the eye except cornea; maintains eye shape
- includes cornea and pupil

16

choroid

darkly pigmented vascular layer
- absorbs light rays not absorbed by retina
- includes iris and ciliary body (muscle that control shape of lens)

17

retina

inner layer containing photoreceptors
