Task: Class Definition Understanding (ontology: Sciences/Biology)

Which of the following definitions best describes 'non-myelinating Schwann cell'?

A. A glial cell that develops from a the concept precursor. The the concept is embedded among neurons (axons) with minimal extracellular spaces separating them from nerve cell membranes and has a basal lamina. Cells can survive without an axon present. the concept can be found communally ensheathing large groups of axons.
B. A glial cell that ensheaths multiple small diameter axons in the peripheral nervous system. The the concept is embedded among neurons (axons) with minimal extracellular spaces separating them from nerve cell membranes and has a basal lamina. Cells can survive without an axon present. These cells can de-differentiate into immature Schwann cells.
C. A neuroglial cell of the peripheral nervous system inside the basal lamina of the neuromuscular junction providing chemical and physical support to the synapse.
D. A neuroglial cell of the peripheral nervous system which forms the insulating myelin sheaths of peripheral axons.

Answer: A glial cell that ensheaths multiple small diameter axons in the peripheral nervous system. The the concept is embedded among neurons (axons) with minimal extracellular spaces separating them from nerve cell membranes and has a basal lamina. Cells can survive without an axon present. These cells can de-differentiate into immature Schwann cells.
