Diffrent Types Of Receptors

Question 1

What are nerves

Answer 1

Many neuron axons bound together like a thick wire

Question 2

Free nerve endings

Answer 2

Pain (noicepton)

Thermoreceptors

Question 3

Merkel cells

Answer 3

Touch and texture

Slow to adapt and ignore

Question 4

Meissner corpuscule

Answer 4

Touch and movement

Fast to adapt or ignore

Question 5

Ruffini curpsule

Answer 5

Stretch of skin and deep pressure

Question 6

When body temperature rises

Answer 6

Free nerve endings in the skin sense tempature

Send sensory electrical electrical signals up to the hypothalamus

Hypothalamus responds with sympathetic signals back that stimulate sweat glands

Question 7

Sweating allows

Answer 7

Evaporative heat loss from body

Question 8

Increased dermal blood flow

Answer 8

Allows radiation heat loss

Question 9

When body temperature drops

Answer 9

Free nerve endings in the skin sense tempature

Sends sensory electrical signals up to the hypothalamus

Hypothalamus responds with sympathetic signals back that stimulate arrector pili muscles (goose bumps)

Question 10

Hypothalamus increases

Answer 10

Metabolic rate faster metabolism generates heat

Question 11

Hypothalmus decreases

Answer 11

Metabolic rate slower metabolism gives off less heat
