Document Summary
Innervates cardiac muscle, smooth muscle, most exocrine glands, some endocrine glands, and adipose tissue. Make adjustments to ensure optical support for body activities. Body prepares itself for a flight or fight. Unnecessary functions are reduced and energy is diverted to other functions vital to survival. Preganglionic fiber (synapses with cell body of second neuron) Doral root ganglion contains the cell bodies which support the primary sensory neuron axon. Axons of the ans are a two-neuron chain. The preganglionic (first neuron) has a lightly myelinated axon and extends to a ganglion. The postganglionic (second) neuron (unmyelinated) extends to an effector organ. A ganglion is a collection of neuronal cell bodies in the periphery (except for the. Dorsal root ganglia we are already family with (sensory). Now you are introduced to autonomic ganglia (motor) The post ganglionic fiber innervates the effector organ, the spidery ends of the fiber release neurotransmitters .
