Question

1. Using the tip of a pencil, slowly lift (slow movement) a single hair on your own forearm until it springs away (fast movement). Repeat the experiment with two other hairs. Record your sensations relative to slow movement, fast movement, and stationary bending of the hair.

2. 	Sensation during slow movement of hair	Sensation during stationary bending	Sensation during fast movement of hair
   Hair #1
   Hair #2
   Hair #3

3. 1. Which types of touch receptors were most likely stimulated by he hair movement?
4. 2.When are hair root plexuses active? Are they rapidly or slowly adapting receptors?

what should I fill in the table, how strong I feel the movement? and the second question confused me

Answer 1

1. Touch receptors stimulated by the hair movement are called hair root plexus that are receptors in hair follicles. Indeed, hair receptors in the cochlea of the inner ear are the most sensitive mechanoreceptors in humans.

2. Hair root plexus are rapidly adapting touch receptors of the skin. They are the wrapped free nerve endings around the hair follicles. It detects the movement of hair on the skin surface.

Table should be filled personally by experiencing.
