Which statement best defines sensory receptors?

• They are motor end plates that cause muscle contraction

• They are specialized cells or dendrites of a sensory neuron

• They are supportive glial cells within the CNS

• They are chemical messengers released by endocrine glands

What must a sensory receptor be able to do in response to a stimulus?

• Inhibit synaptic transmission in the CNS

• Trigger a nerve impulse that propagates to the CNS

• Release hormones into the bloodstream

• Convert an impulse into a motor response without CNS involvement
