Question

which of the following is true regarding axons in the pns? a schwann cell folds its plasma membrane around several axons. a schwann cells wraps its plasma membrane around each individual axon as it does in the cns. an oligodendrocyte cells wraps its plasma membrane around each axon as it does in the cns. satellite cells cluster around each axon to form a pseudo - myelin sheath. send extensions called perivascular feet to wrap each axon.

Explanation:

In the PNS (peripheral nervous system), Schwann cells are the glial cells. One Schwann cell folds its plasma membrane around several unmyelinated axons. Oligodendrocytes are in the CNS (central nervous system). Satellite cells in the PNS surround neuron cell bodies, not axons for myelination. Astrocytes are also CNS glial cells.

Answer:

A. A Schwann cell folds its plasma membrane around several axons.
