Peripheral Nerve: Low Power

In the low power of a peripheral nerve notice the numerous axons surrounded by a dense connective tissue sheath
This sheath is known as the epineurium

Peripheral Nerve: High Power

In the high power of a peripheral nerve notice that the axons are not all the same diameter
Other cells present include the support cells for axons, Schwann cells and endothelial cells of blood vessels
Note the absence of neuronal cell bodies

Peripheral Nerve:

Peripheral nerves contain only axons, and their support cells which are known as Schwann cells
They may contain (and are likely to contain) axons of both motor and sensory nerves
