Neuronal Cells Top Open Access Journals

A neuron, neurone  or neuron , is an electrically excitable cell that communicates with other cells via specialized connections called synapses. It is the most component of nerve tissue altogether animals except sponges and placozoa. Plants and fungi do not have nerve cells.Neurons are typically classified into three types supported their function. Sensory neurons answer stimuli like touch, sound, or light that affect the cells of the sensory organs, and that they send signals to the medulla spinalis or brain.Motor neurons receive signals from the brain and medulla spinalis to regulate everything from muscle contractions to glandular output. Interneurons connect neurons to other neurons within an equivalent region of the brain or medulla spinalis . A group of connected neurons is named a neural circuit. The signaling process is partly electrical and partly chemical. Neurons are electrically excitable, thanks to maintenance of voltage gradients across their membranes. If the voltage changes by an outsized enough amount over a brief interval, the neuron generates an all-or-nothing electrochemical pulse called an nerve impulse . This potential travels rapidly along the axon, and activates synaptic connections because it reaches them. Synaptic signals could also be excitatory or inhibitory, increasing or reducing internet voltage that reaches the soma.
