Question

label the figure with the following events that occur in response to a fear stimulus. the rate of contraction and relaxation increases. glycogen stores are broken down and glucose is released. epinephrine and norepinephrine are released. frightening stimulus, adrenal gland, kidney, liver, liver cell, heart, heart cell

Explanation:

The fear response starts with a frightening stimulus triggering the adrenal glands to release epinephrine/norepinephrine. These hormones act on the heart (increasing contraction rate) and liver (breaking down glycogen to glucose).

Answer:

• Adrenal gland: Epinephrine and norepinephrine are released.
• Heart cell: The rate of contraction and relaxation increases.
• Liver cell: Glycogen stores are broken down and glucose is released.
