The connective tissue that covers unmyelinated and myelinated axons is called endoneurium.
nervous tissue
Because this is tissue from the brain (CNS), it is an oligodendrocyte which wraps around axons of neurons in the CNS to form a fatty myelin sheath. If it were PNS axons in say spinal or cranial nerves, the answer would be be Schwann cells.
Myelinated axons in the central and peripheral nervous systems.
The axons of nerve cells are surrounded by myelin sheeths - a protective covering that allows for saltatory conduction down the axons, increasing speed and decreasing loss of signal. Axons make up the tissue known as "white matter."

That substance is called the myelin cell or myelin sheath.

The axons and dendrites.
The fat coating around the dendrites and axons is to insulate them.
The Myelin sheath is fat and white and wraps around the fastest axons.
White matter
Myelinated axons in the central and peripheral nervous systems.
