1

How we perceive and respond to our environment is determined by

our ability to sense our environment

2

for the body to perceive a sensation

the NS must have specialized structures to receive/transmit the info to the NS

3

Structures that receive/transmit info to NS

receptors

4

a sensory receptor will detect a stimulus and translate the info into a

action potential

5

after producing an action potential, the info is sent to the

CNS

6

Process by which a sensory receptor will detect a stimulus and translate the info into an action potential, and then send that to the CNS

transduction

7

sensory receptors are the interface between

NS and the internal/external environment of the body

8

What are the general senses

pain
temperature
touch
pressure
vibration
proprioception

9

what are the special senses

olfaction
vision
gustation
equilibrium
hearing

10

the receptors for special senses are _______ than those of the general senses

more complex

11

where are the receptors for special senses located

sense organs

12

special sense receptors are _______ to specific sensations

specific/unique

13

when a stimulus is repeated in the NS a ________ in the sensitivity of a constant stimulus will occur

reduction

14

reduction of a stimulus

adaption

15

adaption reduces the _______ that reaches the CNS

amount of info

16

where are general receptors found

all over the body

17

how many types of general receptors are there

4

18

what are the general receptors

nociceptors
thermoreceptors
mechanoreceptors
chemoreceptors

19

nociceptors

pain receptors

20

nociceptors respond to

tissue damange

21

what neurotransmitter is involved with transmission of pain

substance P

22

what tract is pain transmitted on

spinothalamic tract

23

what fibers is pain carried on

myelinated type A and type C

24

thermoreceptors

temperature receptors

25

where are thermoreceptors located

free nerve endings in the skin, skeletal muscles, and hypothalamus

26

there are _____ more cold receptors than hot receptors

4x

27

thermoreceptors travel on

spinothalamic pathway

28

mechanoreceptors

sensitive to stimuli that distort the cell memebrane of the receptor.

29

how many classes of mechanoreceptors

3

30

what are the classes of mechanoreceptors

tactile
baroreceptors
proprioceptros
