Question

which glial cell is found wrapped around axons in the pns? oligodendrocytes schwann cells nodes of ranvier ependymal cells satellite cells question 21 (1 point) a neuron receives signals from other neurons at what area? the axon terminals the dendrites the axons the nodes of ranvier

Explanation:

1. In the peripheral nervous system (PNS), Schwann cells wrap around axons to form myelin sheaths. Oligodendrocytes perform a similar function in the central nervous system (CNS). Nodes of Ranvier are gaps in the myelin sheath. Ependymal cells line the ventricles of the brain and central canal of the spinal cord. Satellite cells are associated with neuron - cell bodies in ganglia.
2. Neurons receive signals from other neurons at the dendrites. Axon terminals are where a neuron sends signals to other cells. Axons are for transmitting signals away from the cell body. Nodes of Ranvier are involved in the saltatory conduction of nerve impulses along axons.

Answer:

1. B. Schwann cells
2. B. The dendrites
