The Classical Theory of function in the nervous system postulates that the nerve impulse is the result of a sequential reversal of the membrane potential due to an increased permeability of the membrane, first to sodium ions, then to potassium ions. The new theory presents a bio-physical model...

Fill in the blank. Bundles of nerve fibers traveling up or down the white matter of the spinal cord are called ___. Grey and White Matter: Grey matter and white matter are two different types of nervous matter found in the brain and spinal cord...
The heart of each neuron is called the soma - a single thin cable-like fiber known as the axon that sticks out of the soma carries nerve signals away from the neuron, while many shorter branches called dendrites that project from the other end of the soma carry nerve signals to the ...
The small intestine is covered by a network of coupled oscillators, the interstitial cells of Cajal (ICC). These oscillators synchronize to generate rhythmic phase waves of contraction. At points of low coupling, oscillations desynchronise, frequency ste
Placental dysfunction may increase the offspring’s later-life disease risk. The objective of this systematic review was to describe associations between pathological placental changes and neuropsychological outcomes in children after the neonatal period. The inclusion criteria were human studies; original re...
The cells capable of encoding noxious stimuli, nociceptive neurons, originate from neural crest stem cells that migrate dorsally from the neural tube and develop late during neurogenesis. Their cell bodies are in the dorsal root ganglion (DRG) and give rise to an axon characterised by a ...
The spatial organization of glucose metabolism machineries across axon.A. Upper panel: Heat map description of the degree of energy consumption by each axonal activity within three axonal subdomains. Bottom panel: the intensity of each feature/parameter of glucose metabolism machineries within three axon...
Since, the chemicals are absent at the dendritic end of neuron, the nerve impulse can go across only from one side (which contains the chemical substance). In this way, it is ensured that nerve impulses travel in only one direction (through of particular set of neurons). Show More ...
the end of the neuron in a structure called the axon. At the end of the axon is physical gap called a synapse. Nerve impulses cannot jump across the synapse to the next nerve cell without the help of chemical transmitters that are merely messengers that move the impulse across the gap. ...
