Lab 5 (Part 3: Reflexes)

Question 1

What causes a REFLEX to occur?

Answer 1

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

Question 2

Where does an INTEROCEPTOR gather info from?

Answer 2

From inside the body e.g. monitors internal systems

Question 3

Where does an EXTEROCEPTOR gather info from?

Answer 3

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