A benign peripheral nerve sheath tumor is a schwannoma or neurofibroma.
Theca- is the medical terminology combining form meaning sheath. For instance, the spinal cord has a theca, and intrathecal injections can be made within it.
Athecal
Schwann cells form a myelin sheath around peripheral nerve fibers in the peripheral nervous system.
Neurilemmomas are benign, encapsulated tumors of the nerve sheath.
Ganglion cyst
axons of neurons in the peripheral nervous system. The myelin sheath helps to insulate the axon and improve the speed of electrical signal conduction along the neuron. Schwann cells are also involved in nerve regeneration and support neuron function within the peripheral nervous system.
Myelin is a fatty sheath around axons found in the peripheral nervous system.
The medical term is "myelin sheath." This is a fatty substance that surrounds and insulates nerve fibers, allowing for faster nerve impulse transmission. Damage to the myelin sheath can result in conditions such as multiple sclerosis.
A benign spindle cell neoplasm is a tumor that develops in connective tissue other than bone such as skeletal muscle, fat, tendon, fibrous tissue and nerve and blood vessel tissue. The most common benign soft tissue tumor is called a lipoma.
Axons are surrounded by myelin sheath, a fatty material that insulates and protects the axon. Additionally, axons are also surrounded by Schwann cells in the peripheral nervous system and oligodendrocytes in the central nervous system, which help form the myelin sheath.
The glial cells: oligodendrocytes for central nervous system and schwann cells for peripheral nervous system.
