What else can I help you with?
Gray matter in the spinal cord is mostly?
unmyelinated axons.
What can be defined as billions of neuroglial nerve cell bodies and unmyelinated axons?
Gray matter in the brain and spinal cord can be defined as billions of neuroglial nerve cell bodies and unmyelinated axons. It is responsible for processing information, including sensory perception, decision-making, and motor control.
What makes the matter gray?
Grey matter is nerve tissue that primarily consists of nerve cell bodies, dendrites, and unmyelinated axons, thus having a gray appearance.
What is the portion of the spinal cord made up of cell bodies and unmyelinated axons?
Gray matter
Does Gray matter contain collections of unmyelinated fibers and cell bodies in the central nervous system?
True
Are unmyelinated cortical fibers found in the cerebral hemispheres?
Yes, unmyelinated cortical fibers can be found in the cerebral hemispheres. These fibers are a type of nerve cell projection that lack the protective myelin sheath, which is typically found in myelinated fibers. Unmyelinated fibers are involved in transmitting nerve impulses and can be found throughout the brain, including the cerebral hemispheres.
What is a word for nerve cell bodies outside CNS?
ganglia is a group of cell bodies in the PNS.
Which cell process are not myelinated?
According to McGraw Hill (please see related link below): Many nerve fibers in the CNS and PNS are unmyelinated. In the PNS, however, even the unmyelinated fibers are enveloped in Schwann cells. In this case, one Schwann cell harbors from 1 -12 small nerve fibers in grooves in its surface. The Schwann cell's plasma membrane does not spiral repeatedly around the fiber as it does in a myelin sheath, but folds once around each fiber and somewhat overlaps itself along the edges. This wrapping is the neurilemma (also called a mesaxon in unmyelinated nerve fibers). Also, gray matter of the brain and dendrites are unmyelinated, while axons are myelinated.
What is the color of nerve cell?
nerve cell can be of many colours like green,white,brown.
A group of nerve cell bodies in the peripheral nervous system is called a?
A group of nerve cell bodies in the peripheral nervous system is called a ganglion. Ganglia serve as processing centers for incoming sensory information and can also contain nerve cell bodies involved in motor control.
Collection of nerve cell bodies found outside CNS?
In the peripheral nervous system, which is outside the central nervous system (CNS), collections of nerve cell bodies are called ganglia.
Why is brain called gray matter?
The brain is called gray matter because it appears gray in color when seen in a preserved or dissected state. This color comes from the cell bodies, dendrites, and unmyelinated axons of neurons in the brain.
