Flashcards in Lab 5 (Part 3: Reflexes) Deck (15):
1

What causes a REFLEX to occur?

RELFEXS are initiatedwhen a SENSORY RECEPTOR is stimulated, and an EFFECTOR (e.g. MUSCLE or GLAND) responds

2

Where does an INTEROCEPTOR gather info from?

From inside the body e.g. monitors internal systems

3

Where does an EXTEROCEPTOR gather info from?

From outside the body e.g. touch, pressure, smell, other senses

4

What kind of stimulus does a NOCICEPTOR respond to?

Pain

5

What kind of stimulus does a THERMORECEPTOR respond to?

Change in temp.

6

What kind of stimulus does a CHEMORECEPTOR respond to?

Food, O2, CO2, glucose, amino acids

7

What kind of stimulus does a PHOTORECEPTOR respond to?

Light

8

What kind of stimulus does a MECHANORECEPTOR respond to?

Touch, pressure, muscle, tendon, sound waves, motion

9

What kind of stimulus does a PROPRIOCEPTOR respond to?

Muscle or tendon tension

10

What kind of stimulus does a BARORECEPTOR respond to?

Pressure changes (BP)

11

What kind of stimulus does a TACTILE RECEPTOR respond to?

Touch
