Gray matter consists of... cell bodies, dendrites, and unmyelinated axons myelinated axons unmyelinated axons myelinated cell bodies, dendrites, and axons

. Describe the basic pathway of information flow throughneurons that causes you to turn your head when someone calls your name.

Identify and describe the following on the diagrams below:   1. Dendrites   2. Axon   3. Cell body     4. Myelinated nerve fiber

Name: The Neuron 1. Processes that carry the action potential (impulse) away from the cell body are called 2. The short, numerous, receptive processes of a neuron are called 3. Gaps in the myelin sheath are called the 4. The CNS consists of the and 5. The PNS consists of the nerves and nerves. 6. Neurons that carry an impulse from a sensory receptor to the CNS are called neurons. 7. Neurons that carry an impulse from the CNS to a muscle or gland are called neurons. 8. Regions of the brain and spinal cord that contain myelinated fibers are referred to as matter. Areas with unmyelinated cell bodies are referred to as matter. 9. Label each of the indicated structures on the neuron below: This neuron is representative of the type of known as a neuron.

Distinguish between insulation by oligodendrocyte or Schwann cells. Relate myelination to signal speed.  Describe the myelin-related terms: neurilemma, nodes of Ranvier, internodes, nonmyelinated

Myelin sheaths function to electrically insulate neurons. Compare and contrast the myelination in the CNS and PNS (hint: include the cell types and their specific properties).

Name the neuroglia and describe their roles

n multiple sclerosis, which type of cell is attacked by the immune system, causing a deficiency of myelin on CNS axons?A: neuronB: microglial cellC: ependymal cellD: oligodendrocyte

please answer the question underlined

List and describe structures and functions of neuroglia of the peripheral nervous system.
