What occurs when the sympathetic nervous system is stimulated?
Uterine activity
Cardiac output
Pancreatic activity
Gastrointestinal activity
The Correct Answer is B
When the sympathetic nervous system is stimulated, it activates the "fight or flight" response, which prepares the body for physical activity or stressful situations. This response includes several physiological changes, such as:
Increased heart rate and cardiac output: The sympathetic nervous system releases adrenaline and noradrenaline, which increase heart rate and cardiac output to provide more oxygen and nutrients to the muscles.
Decreased uterine activity: The sympathetic nervous system inhibits uterine contractions to prevent
premature labor.
Decreased pancreatic activity: The sympathetic nervous system inhibits insulin secretion and promotes glucagon secretion to increase blood glucose levels.
Decreased gastrointestinal activity: The sympathetic nervous system inhibits digestive functions to divert blood flow to the muscles.

Dermal papillae are small, raised structures in the dermis of the skin. They contain nerve endings, capillaries, and other specialized cells. Dermal papillae are responsible for creating fingerprints, as they push up into the epidermis and create ridges on the surface of the skin. These ridges are what give each person their unique pattern of fingerprints. Sudoriferous glands are responsible for producing sweat, Merkel cells are involved in touch sensation, and arrector pili are responsible for the contraction of hair follicles
Correct Answer is A
Explanation
Ceruminous glands are specialized sweat glands located in the skin of the ear canal. These glands secrete a waxy substance called cerumen or ear wax. Ear wax helps to lubricate and protect the skin of the ear canal and prevent the entry of foreign particles, such as dust and insects, into the ear. It also has antibacterial properties that help to protect the ear from infection. The amount and composition of ear wax vary from person to person and can be affected by factors such as age, genetics, and environmental conditions.
