Exempel på hur man kan använda AXONAL i en mening

• T2 hyperintensity, an area of high intensity on types of MRI scans of the brain that reflect lesions produced largely by demyelination and axonal loss.
• It enters the nervous system at the neuromuscular junctions and migrates through nerve trunks and into the central nervous system (CNS) by retrograde axonal transport by using dyneins.
• He discovered the axonal growth cone, and demonstrated experimentally that the relationship between nerve cells was not continuous, or a single system as per then extant reticular theory, but rather contiguous; there were gaps between neurons.
• Instead, it is largely a collection of axonal projections from the hypothalamus that terminate behind the anterior pituitary, and serve as a site for the secretion of neurohypophysial hormones (oxytocin and vasopressin) directly into the blood.
• The active movement of kinesins supports several cellular functions including mitosis, meiosis and transport of cellular cargo, such as in axonal transport, and intraflagellar transport.
• When the toxin keeps the channels in their open state, the nerves cannot repolarize, leaving the axonal membrane permanently depolarized, thereby paralyzing the organism.
• In another development, Damasio proposed that the cortical architecture on which learning and recall depend involves multiple, hierarchically organized loops of axonal projections that converge on certain nodes out of which projections diverge to the points of origin of convergence (the convergence-divergence zones).
• It is now thought that the earliest site of action potential initiation is at the axonal initial segment: just between the peak of the axon hillock and the initial (unmyelinated) segment of the axon.
• They may be divided according to the type of axon affected (large-fiber, small-fiber, or both), the most distal portions of axons are usually the first to degenerate, and axonal atrophy advances slowly toward the nerve's cell body.
• In axonal transport (also known as axoplasmic transport) materials are carried through the axoplasm to or from the soma.
• Wallerian degeneration occurs after axonal injury in both the peripheral nervous system (PNS) and central nervous system (CNS).
• Besides mechanical breakage of the axonal cytoskeleton, DAI pathology also includes secondary physiological changes, such as interrupted axonal transport, progressive swellings known as axonal varicosities, and degeneration.
• It appears that after the initial axonal contact, the newly formed myotube proceeds to grow symmetrically from that point of innervation.
• The mildest grade is referred to as neurapraxia and is characterized by a reduction or complete blockage of conduction across a segment of nerve while axonal continuity is maintained and nerve conduction is preserved.
• Neuron-specific enolase and axonal heavy chain neurofilament blood markers may predict conversion to affected status.
• Animal studies have demonstrated that pentoxifylline can inhibit TNF and, in turn, prevent retinal ganglion cell death and axonal degeneration associated with optic neuropathy in a dose-dependent manner.
• Semaphorins: The many types of semaphorins are primarily axonal repellents, and activate complexes of cell-surface receptors called plexins and neuropilins.
• Studies in multiple organisms including, mice, rats, chicks, the nematode Caenorhabditis elegans, the fruit fly Drosophila melanogaster and the zebrafish Danio rerio have indicated that secreted netrins are bifunctional, meaning that they can act as either attractants or repellants in directing axonal extension.
• Giant axonal neuropathy is a rare, autosomal recessive neurological disorder that causes disorganization of neurofilaments.
• A variant of diffusion weighted imaging, diffusion spectrum imaging (DSI), was used in deriving the Connectome data sets; DSI is a variant of diffusion-weighted imaging that is sensitive to intra-voxel heterogeneities in diffusion directions caused by crossing fiber tracts and thus allows more accurate mapping of axonal trajectories than other diffusion imaging approaches.
