Senses

Question 1

Sensation

Answer 1

Sensory organs and the nervous system respond to stimuli.

Question 2

Perception

Answer 2

Refers to the more complex organizing of sensory information within the brain

Question 3

Sensory receptors

Answer 3

Specialized structures that respond to physical stimuli by producing electrical changes that cause AP

Question 4

Sensory Neurons

Answer 4

Specialized neurons that carry information from sensory receptors

Question 5

Where are sensory areas?

Answer 5

Cerebral cortex

Question 6

What is transduction?

Answer 6

The process by which a receptor cell produces an electrical charger in response to physical stimuli

Question 7

Receptor potential

Answer 7

The electrical change needed for a stimulus response

Question 8

Sensory Coding

Answer 8

The preservation of relevant information from physical stimuli

Question 9

Sensory Adaptation

Answer 9

Changes in sensitivity to stimuli. You put on a watch and you feel it at first, then you don’t.

Question 10

Glomeruli

Answer 10

Receive signals from olfactory nerves and organizes them.

Question 11

Activation of receptors on olfactory epithelium causes?

Answer 11

Depolarization

Question 12

What connects the mouth to the nasal cavity?

Answer 12

Nasal Pharynx

Question 13

How do we taste?

Answer 13

The chemical is dissolved in saliva and ender the taste buds, where there are receptors that will send the signal to the brain.

Question 14

What kind of receptor sites for taste has the most binding sites?

Answer 14

Bitter. Protects us for toxic things.

Question 15

Where do you feel pain?

Answer 15

In the brain

Question 16

A fibers

Answer 16

They are myelinated and send their signals very quickly

Question 17

C fibers

Answer 17

They are slow, cause for long lasting pain

Question 18

Where do pain neurons terminate?

Answer 18

In the spinal cord and brain stem

Question 19

What is the cortex responsible for locating pain

Answer 19

The somatosensory Cortex

Question 20

What cortex is responsible for motivation for escaping pain?

Answer 20

The Insular Cortex

Question 21

What cortex makes you worry about pain (emotion)

Answer 21

The pre frontal cortex

Question 22

Gate Control Theory

Answer 22

Theory that explains how we can make it through pain during stressful situations. Via regulation of endorphins and blocking signals

Question 23

What is the pain inhibition of the brain?

Answer 23

Periaqueductal Gray (PAG). Morphines act on this to lower pain.

Question 24

Stress Induced Analgesia

Answer 24

Decreased pain sensitivity that accompanies highly stressful situations.

Question 25

Belief induced analgesia

Answer 25

Dramatic reduction of pain through power of faith.

Question 26

What does high amplitude in sound cause?

Answer 26

Loudness (more energy)

Question 27

What does frequency in sound do?

Answer 27

Pitch

Question 28

Where does transduction occur in the ear?

Answer 28

In the cochlea.

Question 29

What is inside the cochlea?

Answer 29

The basilar membrane has receptor cells that are hair cells.

Question 30

What are the ossicles of the ear and what do the push sound to?

Answer 30

Hammer, anvil, stirrup. They vibrate the oval window

Question 31

How do we know where sounds come from?

Answer 31

Inter-arrival interval & Intensity differences

Question 32

What is Phonemic Restoration

Answer 32

Fill in missing parts of sound with static and we can fill it out.

Question 33

What is psychophysics?

Answer 33

The study of relationships of thresholds.

Question 34

What is absolute threshold?

Answer 34

The faintest detectable stimulus of any given type

Question 35

Just notable difference

Answer 35

The minimal difference in magnitude between two stimuli that is required for the person to notice there is a difference. This is defined by webers law ( a proportional law)

Question 36

What is the hole in your vision called?

Answer 36

Scotoma
