cytology and histology

When medical students study all of the structures in a particular area of the body as a unit (for example, all the muscles, blood vessels, and nerves of the leg), that approach is called

regional anatomy

Both anatomists and physiologists are aware that form and function are interrelated.

True

The fact that the structures of cells vary widely reflects the specializations needed for their different functions.

True

For better retention of material, it is better to break up study sessions into multiple smaller chunks (e.g. 30 minutes each) rather than fewer, longer sessions (e.g. several hours each).

True

Which of the following choices places the components of a homeostatic control system in proper order?

Stimulus, receptor, control center, effector

When you are exposed to bright light, a reflex is initiated and the muscles of your iris contract to decrease your pupil size.  The iris muscles are acting as a(n)

effector.

If your body temperature starts to decline, your body responds by exciting skeletal muscles so that you shiver and your temperature returns to normal.  This is an example of negative feedback.

True

Diagnosing a disease involves determining the

cause of the homeostatic imbalance.
