What is the name of covering of axon?
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.
What neurons normally have the shortest axons?
somatic motor neurons
What two cells form the insulating sheaths around axons?
Schwann cells and oligodendrocytes
When your hit in the head do you damage the neurons in your brain or the axons?
When you are hit in the head, both neurons and axons can sustain damage. Neurons are the specialized cells responsible for transmitting electrical signals in the brain, while axons are long, slender projections that extend from neurons and transmit those signals to other neurons or tissues. Impact to the head can cause direct damage to neurons and axons, leading to functional impairment or cell death.
What substances carry a nerve impulse?
Neurons and their axons
What are swann cells?
Schwann cells are cells that surround the axons (nerve fibre) of neurons providing the myelin sheath. They are associated with neurons in the peripheral nervous system.
What cells in the peripheral nervous system that form a covering around axons?
Schwann cells wrap around the AXONS of peripheral neurons.
How do you create myelenated neurons?
You don't, but glial cells, (oligodendrocytes in the CNS, and Schwann cells in the PNS), wrapped one after another around the axons of neurons with gaps between them called the nodes of Ravnier do create myelinated neurons.
What is the purpose of myelin sheath?
This is a process that occurs in the CNS and PNS with axons. In the CNS oligodendrocytes surround the axons and in PNS schwann cells surround the axons. the myelin sheath will increase the speed of nervous conduction along the axon.
What supports the cells of nervous system?
glial cells (sometimes called neuroglia).In the peripheral nervous system, Schwann cellsform a myellin sheath around axons, and in the central nervous system, Oligodendrocytes do the same thing for the neurons there; and Astrocytes (Astroglia) surround brain neurons to hold them in place, provide nutrients and oxygen to them, insulate neurons from one another, destroy pathogens and remove dead neurons, and possibly in some ways modulate neurotransmission.

Which best describes the components of a nerve?
axons, blood vessels, connective tissue, Schwann cell.
Which bestdescribes thecomponents ofa nerve?
axons, blood vessels, connective tissue, Schwann cell.
What is the difference between Schwann cells and oligodendrocytes?
1) starting with the obvious; oligodendrocytes myelinate axons in the CNS whereas schwann cells myelinate axons in the PNS 2) a single oligodendrocyte is able to myelinate multiple axons whereas a schwann cell can only myelinate a single axon. 3) schwann cell myelination allows for axonal grown and regeneration where as oligodendrocytes inhibit axonal growth and regeneration. 4).... and probably a bunch more differences
What neurons normally have the shortest axons?
somatic motor neurons
How do Schwann cells and astrocytes differ?
A+ Students - myelin sheath A Schwann cell is a particular type of neuroglial cell, found only in the peripheral nervous system. Schwann cells produce the myelin sheath, which insulates the axons of bodily nerves, increasing the signal velocity.
The neurilemma of axons in the peripheral nervous system is formed by?
schwann cells
