Verified step by step guidance

Understand the concept of an autonomic plexus: An autonomic plexus is a network of nerves that contains axons from both the sympathetic and parasympathetic divisions of the autonomic nervous system. These plexuses are involved in regulating involuntary functions such as heart rate, digestion, and glandular activity.

Review the role of sympathetic axons: Sympathetic axons are part of the autonomic nervous system and are responsible for the 'fight or flight' response. They increase heart rate, dilate airways, and inhibit digestion during stressful situations.

Review the role of parasympathetic axons: Parasympathetic axons are also part of the autonomic nervous system and are responsible for the 'rest and digest' response. They decrease heart rate, stimulate digestion, and promote relaxation.

Clarify why somatic motor axons and sensory axons are not part of the autonomic plexus: Somatic motor axons control voluntary movements of skeletal muscles, while sensory axons transmit information from sensory receptors to the central nervous system. These axons are not involved in autonomic functions and are therefore not part of the autonomic plexus.

Conclude that autonomic plexuses contain both sympathetic and parasympathetic axons, as these are the two divisions of the autonomic nervous system responsible for regulating involuntary physiological processes.
