Accessory Structues

Modify the energy created by something in the environment; ears, eyes, etc.

1

Transduction

Process of converting incoming energy into neural activity.

2

Sensory Receptors

Detect certain forms of energy; primary afferent neurons

3

Adaptation

Responsiveness to an unchanging stimulus decreases over time.

4

Coding

Translation of the physical properties of a stimulus into a pattern of neural activity that specifically identifies those physical properties.

5

Temporal Code

Timing of firing

6

Spatial Code

Location of firing

7

Tympanic Membrane

Ear drum

8

Cochlea

Ear; where transduction occurs

9

Auditory Nerve

Axon going to the brain

10

Eye Parts

-Cornea: transparent protective layer
-Pupil: opening behind cornea
-Iris: color of the eye, controls the size of the pupil
-Lens
-Retina: back of the eye

11

Photoreceptors

Concert light energy into neural activity; contain photopigments, chemicals that respond to light

12

Ganglion Cells

Cells that generate action potentials capable of traveling the distance between the eye(retina) to the brain.

13

Proprioceptive Senses

Allows us to know about where we are and what each part of our body is doing.

14

Vestibular Sense

Head movements

15

Vestibular sacs

Help with balance
