○ it has highly sensitive pain receptors

the part of your ear that you can touch on the side of your head is called the:
○ ossicle
○ tympanic membrane
○ auricle
○ external auditory meatus

Explanation:

Question 49 (Parasympathetic Division)

The parasympathetic division (rest - and - digest) has effects opposite to the sympathetic. Increased heart rate (sympathetic), pupil dilation (sympathetic), and decreased digestive juices (sympathetic) are incorrect. Bronchoconstriction occurs as parasympathetic slows breathing, constricting bronchi.

The cornea is avascular (no good blood supply), it actively pumps Na⁺, regenerates quickly, and has sensitive pain receptors. So the statement "it has a good blood supply" is false.

The auricle (pinna) is the outer, touchable part of the ear. Ossicles are middle ear bones, tympanic membrane is the eardrum, and external auditory meatus is the ear canal opening.

Answer:

B. bronchoconstriction
