Pain and Temperature

Question 1

What is haptic perception?

Answer 1

The exploration of objects through touch, most often by the hand or fingers

Question 2

Are temperature and nociception fast or slow?

Answer 2

Slow

Question 3

What receptor do we use to sense temperature, that is also sensitive to pain, and how does it work?

Answer 3

TrypV1 located in the membrane of cells. When the cell is poked, thousands of cells are broken up and releases different molecules that bind to the TrypV1 receptor, causing a conformational change, which activates the cell and sends the signal to the brain

Question 4

What are the fast, medium, and slow types of nerve fibers?

Answer 4

A-beta fibers: fast and thick, covered in myelin (less resistance, high conductance)
A-delta: smaller in diameter, less myelin
C fibers: small diameter, unmyelinated (lingering sense of pain)

Question 5

How can spice change conformation as well?

Answer 5

Capsacin binds the TrypV1 receptor in your tongue and triggers the same response
