Question

A single schwann cell can myelinate how many axons

Answer 1

Answer:

Explanation:

In myelinated axons, Schwann cells form the myelin sheath. The sheath is not continuous. Individual myelinating Schwann cells cover about 100 μm of an axon—equating to about 10,000 Schwann cells along a 1-m length of the axon.

Answer 2

A Schwann cell can form only one internode of myelin around an axon.

Neuron:

• Neurons are the basic units of the brain and nervous system, the cells that receive sensory input from the outside world, send motor commands to our muscles, and transform and relay electrical signals at every step in between.
• The neuron is the brain's fundamental working unit, a specialized cell designed to transmit information to other nerve cells, muscle cells, or gland cells.
• Neurons are nervous system cells that transmit information to other nerve cells, muscle cells, or gland cells.

Axon:

• Each neuron in your brain has one long cable that runs away from the cell's main body.
• This cable is called an axon, and it is where electrical impulses from the neuron travel to be received by other neurons. It is several times thinner than human hair.
• An axon is a thin fiber that extends from a neuron or nerve cell and transmits electrical signals to aid in sensory perception and movement.
• Each axon is encased in a myelin sheath, a fatty layer that insulates the axon and aids in signal transmission over long distances.

Schwann cell:

• A myelin sheath is formed by a Schwann cell wrapping its plasma membrane concentrically around the inner axon.
• The inner turn of the glial cell membrane spirals around the axon to add membrane layers, or lamellae, to the myelin sheath while the nucleus remains fixed.
