Question

question 10
in comparison with the nervous system, the regulatory effects of the endocrine system are:
rapid to appear but short - lived.
slow to appear but long - lasting.
rapid to appear and long - lasting.
slow to appear and short - lived.
question 11
the two - point discrimination test can be used to measure:
visual acuity.
the ability to determine the location of a sound.
the sensitivity of the skin in various parts of the body.
the ability to measure the relative temperature of two different objects.
question 12
movement of hair cells in the organ of corti against the ______ membrane can stimulate nerve impulse condition.
tectorial
basilar
vestibular
cochlear

Explanation:

• Question 10: The endocrine system releases hormones into the bloodstream. Hormone transport and action take time (slow - to - appear), but their effects can persist for a relatively long time compared to the nervous system's rapid, short - lived electrical impulses.
• Question 11: In the two - point discrimination test, two points (e.g., from calipers) are applied to the skin. The minimum distance at which a person can distinguish two points from one point varies across body parts (more sensitive areas like fingertips have a smaller two - point threshold).
• Question 12: In the organ of Corti, hair cells are embedded in the basilar membrane. When the basilar membrane vibrates (due to sound waves), the hair cells move against the tectorial membrane, which leads to the generation of nerve impulses.

Answer:

• Question 10: slow to appear but long - lasting.
• Question 11: the sensitivity of the skin in various parts of the body.
• Question 12: tectorial.
