4.8.2 Describe myelination by Schwann cells and oligodendrocytes, the nodes of Ranvier and the connective tissue sheaths of a peripheral nerve.

Why this video

It explains the differences between peripheral and central myelination by Schwann cells and oligodendrocytes, including the role of myelin and nodes of Ranvier in nerve conduction.

Part of this line

Covers part of this objective. It leaves out: It does not cover the three connective tissue sheaths of a peripheral nerve (endoneurium, perineurium, and epineurium).

Heads up

Keep in mind the course convention that a single oligodendrocyte in the CNS can myelinate segments of up to 40 to 50 axons.
