Autonomic Plexuses

Front

What is the celiac ganglion and plexus responsible for?

Back

The celiac ganglion and plexus are responsible for innervating the abdominal organs, including the stomach, liver, pancreas, and intestines, and play a key role in the autonomic nervous system.

Front

What structures are included in the pulmonary plexus?

Back

The pulmonary plexus includes autonomic nerve fibers that innervate the lungs and bronchi, regulating bronchoconstriction and bronchodilation.

Front

What is the function of the cardiac plexus?

Back

The cardiac plexus is responsible for regulating heart rate and cardiac output through autonomic innervation, influencing both sympathetic and parasympathetic responses.

Front

What is the esophageal plexus and its role?

Back

The esophageal plexus is a network of nerves that innervates the esophagus, facilitating peristalsis and regulating the function of the esophageal sphincters.

Front

What does the lesser splanchnic nerve innervate?

Back

The lesser splanchnic nerve innervates the kidneys and adrenal glands, providing sympathetic innervation to these organs.

Front

What is the autonomic nervous system?

Back

The autonomic nervous system is a part of the peripheral nervous system that controls involuntary bodily functions, including heart rate, digestion, and respiratory rate.

Front

What are the two main divisions of the autonomic nervous system?

Back

The two main divisions of the autonomic nervous system are the sympathetic nervous system and the parasympathetic nervous system.

Front

How does the sympathetic nervous system affect the body?

Back

The sympathetic nervous system prepares the body for 'fight or flight' responses, increasing heart rate, dilating airways, and inhibiting digestion.

Front

What is the role of the parasympathetic nervous system?

Back

The parasympathetic nervous system promotes 'rest and digest' activities, slowing the heart rate, increasing intestinal activity, and relaxing sphincter muscles.

Front

What is the significance of autonomic plexuses in the body?

Back

Autonomic plexuses are significant as they integrate and distribute autonomic nerve fibers to various organs, ensuring coordinated physiological responses.
