Ex. 24 Intro to sensory receptors

Question 1

Define modality:

Answer 1

Modality is the “type” of stimuli (light, heat, sound, pressure, and specific chemicals).

Question 2

Define general senses:

Answer 2

General senses are senses that are found in many locations of the body and are found in placees such as the skin, muscle, joints, and viscera. Senses of touch, pressure, changes in temperature, pain, blood pressure, and stretching are general senses.

Question 3

Define special senses:

Answer 3

Special senses occur in spacific locations, such as the eye, ear, tongue, and nose and include taste, smell, sight, hearing, and balance.

Question 4

Define exteroceptors:

Answer 4

.

Question 5

Define interoceptors:

Answer 5

.

Question 6

Define proprioceptors:

Answer 6

detect changes in the position of the body and in tension, such as those in tendons when a muscle contracts

Question 7

What’s the difference btw exteroceptors & interoceptors & proprioceptors?

Answer 7

.

Question 8

Define referred pain & give an example:

Answer 8

The perception of pain in one area of the body when the pain is somewhere else. This is because neural impulses have convergent pathways here nerves receiving stimuli from the skin or muscle in one area follow the same general ascending tract that sensory information from an organ do. Ex: pain felt in the left shoulder & arm when a person is suffering from a heart attack or chest pain.

Question 9

Whats the difference between general and special senses?

Answer 9

.

Question 10

Photoreceptors respond to what modality?

Answer 10

light (retina of the eye)

Question 11

thermoreceptors respond to what modality?

Answer 11

detect changes in temperature. (located in the skin and other areas)

Question 12

mechanoreceptors respond to what modality?

Answer 12

receptive to mechanical stimuli (ie. touch receptors or receptors in the ear that respond to sound or motion)

Question 13

baroreceptors respond to what modality?

Answer 13

respond to changes in blood pressure

Question 14

chemoreceptors respond to what modality?

Answer 14

respond to changes in the chemical environment (ie. taste & smell)

Question 15

nociceptors respond to what modality?

Answer 15
