Division of the ANS most active when the body is at rest describes the

Focusing the eye on a nearby object in the field of vision is a function of which division of the ANS?

Which division of the autonomic nervous system innervates the sweat glands in skin?

The overall integrating center for the ANS.

Congenital megacolon, or Hirschsprungʹs disease, is a birth defect in which the innervation of the distal region of the large intestine fails to develop normally.

Parasympathetic impulses to the stomach pass through the

The main integration center of the ANS is the amygdala.

In which autonomic division do nerve cell bodies lie closest to the organs being innervated?

Over 90% of all preganglionic parasympathetic fibers are in cranial nerve

The primary integrating center of the ANS is the of the diencephalon.

The adrenal medulla is stimulated by preganglionic neurons localized to gray matter of the spinal cord

The sympathetic and parasympathetic divisions can be distinguished by the amount of branching of the post-ganglionic fibers.

Which autonomic division increases heart rate?

Figure 15.1 Use the diagram above to answer the following questions. -Which letter indicates the left vagus nerve?

All parasympathetic postganglionic fibers of the head travel through the trigeminal nerve (V) to their final destinations.

The cell bodies of postganglionic parasympathetic fibers to the pupil and lens of the eye are located in the ganglion.
