Sympathetic axons reach organs through all of the following except
a. abdominopelvic nerve plexuses.
b. head and neck nerve plexuses.
c. thoracic nerve plexuses.
d. pelvic splanchnic nerves.
e. spinal nerves.
The nervous system plays a major role in controlling different body parts and acts as a communicating system for the body. It is of two different types, such as the central nervous system and the peripheral nervous system.
The central nervous system includes the brain and the spinal cord, while the peripheral nervous system includes the nerves that arise from the spinal cord. Neurons are the structural and functional unit of the brain and the central nervous system.
The autonomic nervous system is a part of the peripheral nervous system, and it controls different involuntary functions, such as blood pressure, heart rate, respiration, digestion, etc. It is divided into three divisions, such as sympathetic, parasympathetic, and enteric nervous systems.
The sympathetic nervous system helps our body with energy situations (fight or flight response) while the parasympathetic nervous system helps our body maintain a calm and composed state. The enteric nervous system, on the other hand, aids in the movement of water and electrolytes between the tissue fluid and gut lumen.
The sympathetic neurons(axons) reach different organs through various nerves, such as follows;
- spinal nerves
- head, neck, thoracic, and abdominopelvic nerve plexuses
Thus, option d is the correct answer, since pelvic splanchnic nerves allow parasympathetic sacral nerve fibers from the spinal cord to pass through to reach the inferior hypogastric plexus.
