exam 1 part 2

Question 1

What are the two layers of the skin?

Answer 1

Epidermis and dermis

The epidermis is the protective layer, while the dermis contains mechanoreceptors.

Question 2

What is the function of the epidermis?

Answer 2

Protective layer of the skin

The epidermis acts as a barrier against environmental damage.

Question 3

What is the function of the dermis?

Answer 3

Contains mechanoreceptors

The dermis is responsible for sensation and support.

Question 4

What do SAI mechanoreceptors detect?

Answer 4

Patterns/shapes of objects

SAI stands for slowly adapting type I mechanoreceptors.

Question 5

What is the role of SAII mechanoreceptors?

Answer 5

Detect stretching of the skin

SAII mechanoreceptors help to perceive how fingers are shaped.

Question 6

What do FAI mechanoreceptors respond to?

Answer 6

Low frequency vibrations

FAI mechanoreceptors are activated when holding objects that are slipping.

Question 7

What do FAII mechanoreceptors detect?

Answer 7

When objects contact our skin

FAII mechanoreceptors are involved in the sensation of touch.

Question 8

How do slow adapting receptors respond?

Answer 8

They respond when there is contact

Slow adapting receptors maintain their response during prolonged stimulation.

Question 9

How do fast adapting receptors respond?

Answer 9

They respond to stimulus onsets and offsets

Fast adapting receptors are sensitive to changes rather than sustained contact.
