This figure compares the organization of the somatic motor system and the autonomic nervous system. Identify structure "C" on the above diagram.

A) Autonomic ganglion
B) Somatic motor neuron
C) Effector organ (smooth muscle of GI tract)
D) Postganglionic neuron
E) Preganglionic neuron

Effector Organ

An organ or tissue that responds to neural or hormonal signals, carrying out the final response or action.

Autonomic Ganglion

A collection of nerve cell bodies in the autonomic nervous system that act as relay points for transmitting neurological signals to organs.

Smooth Muscle

A type of muscle found in the walls of hollow organs like the intestines and blood vessels, characterized by its involuntary control and lack of striations.
