ii. Learned or acquired reflexes – result of practice or repetition
1. Example – driving a car – series of complex movements, but we’re not consciously aware of many of them
-Classification of Sensory Receptors-

_________ – stimulated by touch, vibration, pressure, stretch, and itch

Mechanoreceptors

2

-Classification of Sensory Receptors-

_________ – sensitive to change in temperature

Thermoreceptors

3

-Classification of Sensory Receptors-

_________ – sensitive to light

Photoreceptors

4

-Classification of Sensory Receptors-

_________ – chemicals (smelling and tasting)

Chemoreceptors

5

-Classification of Sensory Receptors-

_________ – pain

Nociceptors

6

- Receptors by Location -

_________ – sensitive to changes outside the body
-Touch, temperature, sight, etc

Exteroceptors

7

- Receptors by Location -

_________ – respond to changes within the body
-Chemical changes, temperature, hunger, pain, etc.

Interoreceptors

8

- Receptors by Location -

_________ – respond to changes within the body but
are restricted to muscles, tendons, joints, and inner ear

Proprioceptors

9

- Receptors by Location -

_________ -Tell us where we are in space by monitoring body position, muscle length and tension, and movement of joints

Proprioceptors

10

- Receptors by Structure -

_________ – bare dendrites
-Detect pain, temperature, itch, tickle and some touch sensations

Free nerve endings

11

- Receptors by Structure -

_________ - Detect pain, temperature, itch, tickle and some touch sensations

Free nerve endings

12

- Receptors by Structure -

_________ – dendrites are enclosed in a capsule
-Detect touch, pressure, and vibration

Encapsulated dendritic endings

13

- Receptors by Structure -

_________ - Detect touch, pressure, and vibration

-Include meissner’s corpuscles, Pacinian corpuscles, and Ruffini’s corpuscles

Encapsulated dendritic endings

14

- Receptors by Structure -

_________ – proprioceptors found in skeletal muscle

-Measure how much a muscle is being stretched
-Impulses are sent to the cerebrum

Muscle spindles

15

- Receptors by Structure -

_________ - Measure how much a muscle is being stretched

-Impulses are sent to the cerebrum (conscious
proprioception) and cerebellum (coordination)

Muscle spindles

16

- Receptors by Structure -

_________ – located at junction of muscle and tendon

-Initiate reflexes that relaxes muscle before it contracts too forcefully

Tendon organs

17

- Receptors by Structure -

_________ - Initiate reflexes that relaxes muscle before it contracts too forcefully

Tendon organs

18

- Receptors by Structure -

_________ – several types of receptors that monitor joint position and movement

Joint kinesthetic receptors

19

- Stimulation of sensory receptor -

1. stimulus must be specific to _________ (i.e. touch receptor doesn’t respond to light)
2. Stimulus must be in receptor’s “_________” – area of the body it is monitoring
**- Converting a stimulus to an action potential **
3. Stimulus must be converted to energy – called transduction
--Causes depolarization or hyperpolarization
4. Generation of impulses – threshold must be reached so an action potential is triggered and impulse is carried towards the CNS
--1st order neurons – conduct sensory impulses from the PNS to the CNS

-receptor
-range

- Stimulation of sensory receptor -

3. Stimulus must be converted to energy – called transduction
