    Study Notes

    Autonomic Nervous System

    • Cell bodies in the sympathetic nervous system are located in the thoracic and lumbar regions of the spinal cord (T1-L2/L3).

    Vagus Nerve

    • The Vagus nerve (cranial nerve X) plays a crucial role in the parasympathetic nervous system, regulating various involuntary functions, such as heart rate, digestion, and respiration.

    Splanchnic Nerves

    • The splanchnic nerves belong to the sympathetic nervous system.
    • They originate in the thoracic region of the spinal cord (T5-L2).

    Parasympathetic Nervous System

    • Cell bodies in the parasympathetic nervous system are located in the brainstem (cranial nerves III, VII, IX, X) and the sacral region of the spinal cord (S2-S4).

    Sympathetic Nervous System Pathway

    • Pre-ganglionic axons originate in the thoracic and lumbar regions of the spinal cord (T1-L2/L3) and travel to the sympathetic ganglia.
    • Post-ganglionic axons originating from the sympathetic ganglia innervate blood vessels.

    Enteric Nervous System

    • The enteric nervous system, often referred to as the "little brain," is a subdivision of the autonomic nervous system that regulates gastrointestinal functions, such as motility, secretion, and blood flow.

    Somatic Nervous System

    • The somatic (voluntary) nervous system involves alpha motor neurons and their axons, responsible for transmitting signals from the central nervous system to muscles and glands.
