What is a specialized cell that conducts impulses through the nervous system?
Neurons transmit and receive signals in the nervous system
The dorsal root of a spinal nerve contain what?
axons of sensory neurons
The term that refers to groups of myelinated axons from many neurons supported by neuroglia is?
White matter (myelin has a whitish color)
Neurons are composed of a network of fine threads called?
Axons of neurons terminate in a series of fine extensions known as dendrites.
What is the process by which axons of healthy neurons adjacent to damaged neurons grow new branches to make up for the damage?
Collateral Sprouting
What neurons normally have the shortest axons?
somatic motor neurons
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.
Groups of axons and dendrites in the PNS are called?
A group of axons in the CNS is most likely referring to the tracts of neurons that are found in the spinal cord.
What are the long arms of neurons called?
axons
The part of a spinal nerve that contains only sensory neurons is the?
The part of a spinal nerve that contains only sensory neurons is called the ventral root. There's also the axons of motor neurons and axons of sensory neurons.
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
Myelinated neurons are embedded in what?
the axons of myelinated neurons are embeded in a protective covering of gray matter.
Axons and dendrites is another word for?
Axons are the output element of a neuron, and dendrites are the input elements of a neuron.
Neuroscientists have studied its very large neurons?
squid axons
What are the thin chain-like extensions of the neurons called?
Axons
What are neurons made up of?
Cell body, dendrites, and axons
