Vagal stimulation of the heart decreases heart rate, resulting in a drop in blood pressure.

Adrenergic hormones are secreted into the bloodstream in this region of the adrenal gland.

The defecation and urination reflexes are integrated in the

What is the effect of parasympathetic stimulation of respiratory bronchioles in the lungs?

The micturition (urination) reflex is controlled by a parasympathetic reflex pathway in which

The general visceral motor division of the peripheral nervous system describes the

The secretions of the adrenal medulla act to supplement the effects of

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

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

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

Sympathetic trunk ganglia contain the cell bodies of sensory neurons and are located in the dorsal root of the spinal cord.

Control of temperature, of autonomic nervous reflexes, of hunger, and of sleep are functions associated with the

The ________ nervous system consists of complete three-neuron reflex arcs that exist entirely within the wall of the digestive tube.

Which division of the nervous system is characterized by highly branched postganglionic fibers that innervate multiple organs?

Parasympathetic stimulation of blood vessels causes vasoconstriction and increased blood pressure.
