- Somatic efferent neurons are motor neurons that conduct impulses from the spinal cord to skeletal muscles. These neurons are multipolar neurons, with cell bodies located in the gray matter of the spinal cord.Somatic efferent neurons leave the spinal cord through the ventral root of spinal nerves.Visceral afferent neurons are sensory neurons that conduct impulses initiated in receptors in smooth muscle & cardiac muscle.he dorsal root is sensory (all neurons conduct impulses into the spinal cord) while the ventral root is motor (all neurons conduct impulses out of the spinal cord). The dorsal root has a ganglion that contains the cell bodies of the sensory neurons that pass through the dorsal root.

Neurons Link to CNS. The cell bodies of the sensory neurons leading to the spinal cord are located in clusters, the dorsal root ganglia (DRG), next to the spinal cord. Their axon extends in both directions: a peripheral axon to receptors at the periphery and a central axon passing into the spinal cord.

Neurons Motor neurons are neurons located in the central nervous system, and they project their axons outside of the CNS to directly or indirectly control muscles. The interface between a motor neuron and muscle fiber is a specialized synapse called the neuromuscular junction.

- BASIC MOTOR PATHWAY. A. An overview: The motor pathways are pathways which originate in the brain or brainstem and descend down the spinal cord to control the a-motor neurons. These large neurons in the ventral horns of the spinal cord send their axons out via the spinal roots and directly control the muscles.

Anatomy Efferent fiber to skeletal muscle. -The cell body of this nerve fiber is located w/in the CNS, either in a nucleus w/in brainstem or in the ventral gray column of the spinal cord (a nucleus equivalent. -This fiber terminates on skeletal muscle and causes it to contract.

- The nerve fibers that innervate skin receptors have their cell bodies in the dorsal root ganglion, a group of neuron cell bodies near the spinal cord. The axons of dorsal root ganglion cells project in to the spinal cord, where they synapse with neurons in the dorsal horn of the grey matter.he nerve ending is the end of a myelinated process (the primary afferent fiber) that extends between the receptor and the cell body in the dorsal root ganglion. Another myelinated process (the central branch) extends from the cell body in the ganglion to terminate in the spinal cord.

- Neuronal types Motor neurons These lower motor neurons are located on the ventral aspect of the cord. They are either alpha or gamma cells. Alpha cells are the principle lower motor neurons of the spinal cord and form the main portion of the final common pathway. They conduct rapid motor impulses, with each alpha cell innervating approximately 200 muscle fibers.

Armpit Pain It causes swelling, pain and fever. This is common during an arm injury causing the axillary lymph nodes under the armpits enlarge. Since a painful lump in the armpit is associated with breast cancer; an infection in the breast tissue of the armpit could also be painful and its inflammation associated with cancer.

Chapter 13 The Peripheral Nervous System and Reflex Activity (TB) Select the statement that is most correct. Ganglia are collections of neuron cell bodies in the spinal cord that are associated with efferent fibers. The dorsal root ganglion is a motor-only structure. The cell bodies of afferent ganglia are located in the spinal cord. Ganglia associated with afferent nerve fibers contain cell bodies of sensory neurons.
