There are two parts to this question. Describe the basics of the sympathetic and parasympathetic divisions of the autonomic nervous system. Compare what happens to the heart rate, digestion, respiration, and pupillary response when under control of each division.

Expert Solution

1. Bodily Functions Of Sympathetic:

Sympathetic is known for Flight-Fight-Fear response. Sympathetic system prepares the body for increased activity of all the systems of the body. It is resonsible for providing quick responses such as when a dog comes after us our heart rate is increased, micturition is inhibited, respiration is increased and our body prepares itself for this stressful condition.

Bodily action of Parasympathetic system:

Parasympathetic system acts just opposite to the sympathetic system. It relaxes the body and normalises all the bodily function. It slows down all the high energy functions. It brings back the body to its normal state.

2. Comparison:

A. Heart rate in sympathetic is increased, in Parasympathetic heart rate is slowed down.

B. Digestion: sympathetic - it decreases the activity of digestive system

Parasympathetic- stimulates activity of digestive system.

C. Respiratory - in sympathetic it dilates the bronchioles , in Parasympathetic constricts the bronchioles.

D. Pupillary response- in sympathetic it dilates, in Parasympathetic pupils constricts.

The sympathetic and parasympathetic divisions usually act antagonistically. However, there are some effectors that are innervated only by the sympathetic nerves. Describe three such unique functions of the sympathetic nervous system and their role in maintaining homeostasis.

A. Describe parasympathetic and sympathetic neurons, taking into account the relative lengths of the fibers, neurotransmitters involved, and receptors that are present at the pre-post ganglionic junctions and postganglionic-target organ junctions (this does NOT include discussion of how the nerves exit the spinal cord). B. Name 5 effects of the flight-or-flight response and 5 effects that target DIFFERENT components than those named for the sympathetic effects of the rest-and-digest response.
