What does the lateral horn of the spinal cord contain?
The lateral horn of the spinal cord is the small lateral projection of grey matter located between the dorsal horn and ventral horn and contain the neuronal cell bodies of the sympathetic nervous system.
What is found in the lateral horn of the spinal cord quizlet?
Lateral gray horn: located in T1-L2 parts of the spinal cord. Contains the cell bodies of autonomic motor neurons, which innervate cardiac muscle, smooth muscle, and glands.
What type of neuron cell bodies are found in the lateral horns quizlet?
The lateral horns contain the cell bodies of autonomic motor neurons, which innervate cardiac muscle, smooth muscle, and glands.
What is found in the gray matter of the spinal cord quizlet?
the GRAY/WHITE matter in the spinal cord consists mainly of myelinated axons.
What are two functions of spinal cord?
The main functions of the spinal cord are:
- To conduct reflexes below the neck.
- To conduct messages from the skin and muscles to the brain.
- To conduct commands from the brain to muscles of the trunk and limbs.
What type of neuron cell bodies are found in the lateral horns?
The lateral horns are present primarily in the thoracic region, and contain the preganglionic visceral motor neurons that project to the sympathetic ganglia (see Figure 1.10C).
What makes up the white matter of the spinal cord quizlet?
The white matter of the spinal cord is composed of myelinated and nonmyelinated nerve fibers that allow communication between different parts of the spinal cord and between the cord and brain.
Where are motor cell bodies located in the spinal cord?
Skeletal (striated) muscle contraction is initiated by “lower” motor neurons in the spinal cord and brainstem. The cell bodies of the lower neurons are located in the ventral horn of the spinal cord gray matter and in the motor nuclei of the cranial nerves in the brainstem.
