Receptors and Effectors

Question 1

What can receptors and effectors form?

Answer 1

part of complex organs

Question 2

Give example of this

Answer 2

Muscle cells in a muscle
Light receptor in the retina of the eye
Hormone secreting cells in a gland

Question 3

How do muscle cells in a muscle work?

Answer 3

Impulses travel along motor neurons and stop at the muscle cells (effectors), causing the muscle cells to contract

Question 4

How do light receptor cells in the retina of the eye work?

Answer 4

The lends focuses light onto receptor cells in the retina. The receptor cells are then stimulated and send impulses along sensory neurons to the brain.

Question 5

How does hormone secreting cells in a gland work?

Answer 5

An impulse travels along a motor neuron and stops at the hormone secreting cells in glands (effectors). This triggers the release of the hormone into the bloodstream.
