Involuntary nerves that stimulate the body in times of stress and crisis are __________ nerves.

Student Response

Value Correct Answer Feedback

A. motor

B. parasympathetic

C. sensory

D. sympathetic 100%

General Feedback:

Rationale: There are two kinds of autonomic nerves: sympathetic, which stimulate the body in times of stress, and parasympathetic, which restore the body to its normal state. Spinal and cranial nerves contain sensory nerves, which carry messages toward the spinal cord and brain. Motor nerves carry messages from the spinal cord and brain to the muscles.

Student Response


A. The blood-brain barrier

B. A neurotransmitter

100%

C. A receptor

D. A synapse

General Feedback:

Rationale: A neurotransmitter is a chemical messenger that is released from the end of a nerve cell to stimulate or inhibit another cell (nerve, muscle, or gland cell). A receptor is an organ that receives nervous stimulation and passes it on to nerves within the body. A synapse is the space through which a nervous impulse is transmitted. The blood-brain barrier includes blood vessels that keep some substances out of brain tissue to protect it from harmful drugs and disease-causing organisms that might be in the blood.Objective: Recognize and define anatomy and physiology terms.Text page(s): 346, 354MTO: Section I, Lessons 5.3 and 5.5
