Nociception
|
Sensing stimuli that are warmer or colder than the body surface.
|
|
Cutaneous System
|
Our touch system, focused on the skin, our sense receptor for touch.
|
|
What are the two parts of the skin?
|
The epidermis and the dermis.
|
|
Epidermis
|
The outer layer of skin, the dead skin cells.
|
|
Dermis
|
The layer below the dermis, this is the layer that contains the mechanoreceptors.
|
|
Mechanoreceptors
|
Touch receptors.
|
|
What are the two types of mechanoreceptors?
|
Encapsulated receptors, receptors that have a capsule or covering over the nerve ending, are responsible for touch. Ereceptors, bare nerve endings, are responsible for pain and temperature perception.
|
|
What are the four types of encapsulated mechanoreceptors?
|
There are four types of encapsulated receptors: merkel receptor, meissner corpuscle, ruffini cylinder, and the pacinian corpuscle.
|
|
What are the two types of non-encapsulated receptors?
|
The two types of non-encapsulated receptors are the free nerve endings and the termoreceptors.
|
|
Which of the encapsulated receptors are closer to the surface?
|
The merkel receptors and the meissner corpuscle are closer to the surface.
|
|
Which of the encapsulated receptors are closer to the subcutaneous fat layers?
|
The ruffini cylinders and the pacinian corpuscle are closest to the subcutaneous fat.
|
|
Which mechanoreceptor is responsible for pain and nociception perception?
|
The free nerve endings are responsible for pain and nociception perception.
|
|
Which mechanoreceptor is responsible for temperature perception?
|
The thermoreceptors are responsible for temperature perception.
