6) CGRP-IR axons did not colocalize with tyrosine hydroxylase or vesicular acetylcholine transporter axons in the stomach, indicating CGRP-IR axons were not visceral efferent axons. (bvsalud.org)

Along that distance, the axon branches out to make hundreds of connections with other cells, sending out signals that allow us to sense and respond to the world around us. (sciencedaily.com)
Axons with both branches cut after a branch point regenerated in 67 percent of cases. (sciencedaily.com)
In contrast, regeneration occurred only 12 percent of cases following cuts to just one of two axon branches after a major branch point. (sciencedaily.com)
The total length of one of these axons, with all its branches, was several times longer than the body of a mouse. (hopkinsmedicine.org)
That is why we can't read Braille using the skin on our backs: the multiple bumps that make up a Braille symbol are within such a small area that the axon branches can't distinguish them. (hopkinsmedicine.org)
At the spinal ganglion, the meninges continue on the main trunk of the spinal nerve and its branches as the epineurium. (veteriankey.com)

The spinal cord is made up of two tissues - white and grey matter. (vetphysionancy.com)
Specialized tissues called meninges cover the brain and spinal cord, and cerebrospinal fluid surrounds and protects the brain and spinal cord. (msdvetmanual.com)

The impulse is sent up the spinal cord and through the brain stem to the thalamus, which is a processing center for sensory information, located deep in the brain. (msdmanuals.com)

They then send on second-order neurons of the dorsal column-medial lemniscal pathway. (wikipedia.org)

This is analogous to the dorsal root ganglion, except that it is associated with a cranial nerve instead of a spinal nerve . (lumenlearning.com)
the spinal ganglion, formerly the dorsal root ganglion, is located in the dorsal root at the junction of the dorsal and ventral roots, near the intervertebral foramen. (veteriankey.com)

The cell bodies of nociceptors are located in the spinal cord. (medlineplus.gov)
Grey matter is found within the medial portion of the spinal cord and has two dorsal or posterior horns that contain cell bodies of sensory neurons and two ventral or anterior horns that contain cell bodies of motor neurons. (osmosis.org)
The DRG contain the sensory cell bodies which send their devel- oping axons into the evolving spinal cord and skin. (pediagenosis.com)

Each dorsal and ventral root is surrounded near the spinal cord by pia and arachnoid trabeculae and then by cerebrospinal fluid in the subarachnoid space. (veteriankey.com)

The gracile nucleus and gracile fasciculus carry epicritic, kinesthetic, and conscious proprioceptive information from the lower part of the body (below the level of T6 in the spinal cord). (wikipedia.org)
the dendritic arbor, the cell body, and the axon. (nih.gov)
Because these connections between neurons are made initially as the body is developing, researchers have sought to restore those developmental conditions to potentially help the damaged cord heal. (technologynetworks.com)
The team in today's study, published in the journal Nature Biomedical Engineering, say detecting signals from spinal motor neurons in parts of the body undamaged by amputation, instead of remnant muscle fibre, means that more signals can be detected by the sensors connected to the prosthetic. (scienceblog.com)
It receives messages, processes information, and then sends signals to the rest of your body telling it what to do. (merckmanuals.com)
Then the brain sends messages to your body. (merckmanuals.com)
The spinal cord also carries messages from the body to your brain. (merckmanuals.com)
The spinal cord's role is to carry signals back and forth between the body and brain. (braininjurysupport.org)
The spinal cord is the pathway that messages use to travel between the brain and the other parts of the body. (braininjurysupport.org)
On the other side of the cell's "body" was another axon that led to the skin. (hopkinsmedicine.org)
Axons transmit the electrical charges away from the cell body. (msdvetmanual.com)
Sensory neurons carry information from the body to the spinal cord or brain stem, and then on to the cerebellum and cerebrum for interpretation. (msdvetmanual.com)
Motor neurons carry responses to the sensory information from the spinal cord and brain to the rest of the body. (msdvetmanual.com)

Spinal cord injuries can bring lifelong paralysis, but new research shows that electrical stimulation of the spine may help some patients regain movement. (livescience.com)
A team of scientists recently reported success in using stem cells to treat paralysis caused by spinal cord damage. (houston-disability-attorneys.com)

Nerve axon regeneration is a relatively slow process compared to reepithelialization or neoangiogenesis. (nikiv.dev)

That's because the spinal cord's neural tissue is notorious for its inability to bridge large gaps and reconnect in ways that restore vital functions. (nih.gov)

The impulse crosses from the nerve cell in the spinal cord to the opposite side of the spinal cord. (msdmanuals.com)

Motor neurons in the ventral region of the spinal cord send axons out toward the periphery ( Fig. 1) . (intechopen.com)

The bodies of the cochlear sensory cells resting on the basilar membrane are surrounded by nerve terminals, and their approximately 30,000 axons form the cochlear nerve. (cloudaccess.net)

Also, the fibrous region is composed of the axons of these neurons that are passing through the ganglion to be part of the dorsal nerve root (tissue source: canine). (lumenlearning.com)
Spinal Cord and Root Ganglion. (lumenlearning.com)

Axons course through the midbrain and pons, and collect to form a tract in the medulla, where is decussates. (ualberta.ca)

In mammals and many higher vertebrates, each muscle fiber typically has a single synaptic site innervated by a single motor axon branch. (intechopen.com)
Once the signal reaches the spinal cord, it's picked up by a motor neuron. (doctorshealthpress.com)
The impulse travels out of the spinal cord along the length of the motor nerve. (msdmanuals.com)
If the sensation occurs suddenly and is severe (as when stepping on a sharp rock or picking up a cup of very hot coffee), the impulse may travel to the spinal cord and directly back to the motor nerve, bypassing the brain. (msdmanuals.com)
The leading cause of spinal cord injuries is motor vehicle accidents. (ehlinelaw.com)
The sensor technology interprets the electrical signals sent from spinal motor neurons and uses them as commands. (scienceblog.com)
A motor neuron is a nerve cell that is located in the spinal cord. (scienceblog.com)
This enabled the team to clearly detect the electrical signals sent from the spinal motor neurons - a process the team liken to amplification of the signals. (scienceblog.com)
Ultimately, the scientists want to decode the meaning behind all signals sent from these motor neurons, so that they can program a full range of arm and hand functions in the prosthetic. (scienceblog.com)
These should be distinguished from diseases in which primarily the axons of motor neurons are affected. (medscape.com)
Within the spinal cord are also contained circuits that give rise to rhythmic motor activity - central pattern generators . (ualberta.ca)
