The function of the axon is to transmit information to different neurons, muscles, and glands. (wikipedia.org)
In certain sensory neurons (pseudounipolar neurons), such as those for touch and warmth, the axons are called afferent nerve fibers and the electrical impulse travels along these from the periphery to the cell body and from the cell body to the spinal cord along another branch of the same axon.

The results show that PCA administration produces a loss of fine 5-HT axon terminals in neocortex and a concomitant reduction in the number of retrogradely labeled neurons in the DR (77% decrease), when compared to controls. (erowid.org)
In contrast, beaded 5-HT axon terminals are spared and the number of labeled neurons in the MR remains unchanged after PCA. (erowid.org)

Myelination serves to insulate the axon to take as much advantage of electrotonic spread, before offering a node which can 'regenerate' the signal via an action potential. (khanacademy.org)

Center for Regenerative Biotherapeutics protocols have been developed to generate adult stem cell-derived bonelike, nerve-like and heart-like tissues. (mayo.edu)
Myosin II interacts with F-actin to generate contractile forces that result in axon retraction. (biologists.com)

We have conducted experiments in the adult rat visual system to assess the relative importance of an absence of trophic factors versus the presence of putative growth inhibitory molecules for the failure of regeneration of CNS axons after injury. (nih.gov)
Growth of nerve axons. (mayo.edu)
SNAT7 is the primary lysosomal glutamine exporter required for extracellular protein-dependent growth of cancer cells. (nih.gov)
Axon guidance is mediated by the effects of attractant and repellent guidance cues on the cytoskeleton of growth cones and axons. (biologists.com)
I investigated the roles of RhoA-kinase and myosin II in semaphorin-3A-induced growth cone collapse and axon retraction. (biologists.com)
I report that semaphorin 3A activates myosin II in growth cones and axons. (biologists.com)
Myosin II activity is required for axon retraction but not growth cone collapse. (biologists.com)
Growth cone collapse is often followed by axon retraction. (biologists.com)
F-actin is concentrated at the growth cone and sparse in the axon ( Letourneau, 1983 ). (biologists.com)
Importantly, repellent guidance cues cause growth cone collapse and depolymerize growth cone F-actin while promoting axon retraction ( Gallo and Letourneau, 2004 ). (biologists.com)
how can myosin II drive axon retraction if the major source of the required substratum for force generation, growth cone F-actin, has been depleted? (biologists.com)

The downside is that in a cell these electronic potentials attenuate quite rapidly and are therefore unsuitable for long-distance signaling. (khanacademy.org)
Future challenges are to determine how the brain controls larval movement via its long-range projections to the body. (elifesciences.org)
A requirement for actin filaments (F-actin) in mediating axon retraction has long been established ( Solomon and Magendantz, 1981 ). (biologists.com)

In placental mammals the largest white matter tract in the brain is the corpus callosum, formed of some 200 million axons in the human brain. (wikipedia.org)
The process by which an undifferentiated stem cell becomes a specialized cell type, such as a heart cell or brain cell. (mayo.edu)
They regulate each and every one of our brain and body functions. (cognifit.com)
As a fundamental part of the CNS, the brain could be defined as the "manager" that controls and regulates the majority of brain and body functions . (cognifit.com)
The average adult brain contains around 100 billion brain cells. (ageuk.org.uk)
The brain accounts for about 2% of total body weight, yet receives 20% of our blood supply and uses 20% of our total calorie intake. (ageuk.org.uk)
But the worm study suggests the true cause is nerve-cell breakage caused by defective beta spectrin, says study co-author and biology Professor Erik Jorgensen, scientific director of the Brain Institute at the University of Utah and an investigator with the Howard Hughes Medical Institute (HHMI). (scienceblog.com)
Another feature of ALSP is swellings called spheroids in the axons of the brain, which are a sign of axon damage. (medlineplus.gov)
The development of hyperosmolality from the water loss can lead to neuronal cell shrinkage and resultant brain injury. (medscape.com)
For example, if a single nerve cell is responsible for monitoring a patch of skin a quarter of an inch square, multiple simultaneous points of pressure within that patch will only be perceived by the brain as a single signal. (hopkinsmedicine.org)
Brain development and psychological development involve continuous interactions between a child and the external environment-or, more accurately, a hierarchy of environments, extending from the level of the individual body cells to the most obvious boundary of the skin. (nationalacademies.org)
Directly inhibiting the cell body plays a key role in synchronizing signal processing and transmission between areas of the brain in, for example, in triggering resting periods. (jku.at)

It is postulated that the deformation of the neuron size activates these cells (thus acting like mechanoreceptors). (medscape.com)

Looking more closely at the mitochondria in treated cells, the researchers found that in some cases mitochondria seemed to be moving back toward the cell body, against the flow of other molecules and organelles, which suggested they were being trafficked back for repair. (genengnews.com)

the mesal, longitudinal, skeletal axis of the body, represented in Branchiostoma and embryos by a membranogelatinous notochord, and in most adult vertebrates by the cartilaginous or osseous centra of the vertebræ and the base of the skull. (wordnik.com)
The central thread in the axon is the axis cylinder. (wordnik.com)
For example, during axial locomotion such as lamprey swimming and Drosophila larval crawling, muscles present in each segment are sequentially activated along the body axis in a stereotypic temporal and spatial pattern ( Grillner, 2003 ). (elifesciences.org)
