What else can I help you with?
What wraps themselves around some axons forming what is known as white matter?
Schwann Cells wrap themselves around some axons forming white matter.
What is another name for Myelinated axons?
In preserved brains, the myelinated axons look white. Therefore, what we call "white matter" is typically made of axons.
The cerebral cortex is the:a.gray matter, the axons and dendrites of neuronsb.gray matter, the cell bodies of neurons?
A.) The grey matter, the axons and dendrites of neurons.
Is white matter dense in myelinated axons?
Yes, white matter is dense in myelinated axons. White matter in the brain and spinal cord is primarily composed of nerve fibers that are encased in myelin sheaths, which give it its white color. Myelination helps to speed up the transmission of nerve impulses along these axons.
What is the white matter of the spinal cord contain?
axons
What is a schwann cell?
A schwann cell are supporting cells of the peripheral nervous system, they wrap themselves around nerve axons.
Gray matter in the spinal cord is mostly?
unmyelinated axons.
Does myelinated axons of the cns make up the white matter of the brain and spinal cord?
Yes, myelinated axons in the central nervous system (CNS) constitute the white matter of the brain and spinal cord. The myelin sheath, which is a fatty substance, surrounds these axons and increases the speed of nerve signal transmission. In contrast, the gray matter primarily consists of neuronal cell bodies, dendrites, and unmyelinated axons. Thus, the distinction between white and gray matter is largely based on the presence of myelinated versus unmyelinated axons.
White matter consists of areas that are dominated by what axons?
Terminals
What is the different between white matter and grey matter?
grey matter- the centre area of the spinal cord that contains cell bodies, their axons and their dendrites. white matter- the outer layer of the spinal cord that contains only myelin coated axons.
The portion of the spinal cord made up of myelinated axons?
White Matter
Are unmyelinated axons in the cerebral cortex?
Yes, unmyelinated axons are present in the cerebral cortex. While many neurons in the cerebral cortex have myelinated axons, some interneurons and shorter local circuit neurons have unmyelinated axons. These unmyelinated axons play a role in the local processing and communication within the cortex.
