How Does An Impulse Travel From One Neuron To Another
Start studying Neuron and Neuron Communication. Learn vocabulary, terms, and more with flashcards, games, and other study tools.
Almost every neurotransmitter can bind to more than one type of receptor, and each neurotransmitter can initiate different signals at the postsynaptic neuron.
A neuron, also known as a neurone (British spelling) and nerve cell, is an electrically excitable cell that communicates with other cells via specialized connections called synapses.All multicellular organisms except sponges and Trichoplax have neurons. A neuron is the main component of nervous tissue. Neurons fall into types. Sensory neurons respond to stimulus such as touch, sound, or light.

a neural impulse(electrical impulse. Then neurotransmitters travel across the synaptic gap and stimulate the dendrites of another neuron and the whole process starts again. n. A synaptic.
Nearly all cell membranes in animals, plants and fungi maintain a voltage difference between the exterior and interior of the cell, called the membrane potential.A typical voltage across an animal cell membrane is −70 mV. This means that the interior of the cell has a negative voltage of approximately one-fifteenth of a volt relative to the exterior.
The Synapse. Neurons have specialized projections called dendrites and axons.Dendrites bring information to the cell body and axons take information away from the cell body.
The movement of positively charged sodium ions across the membrane of a neuron can produce a(n)
In this article, we discuss the most fascinating cell type in the human body. We explain what a neuron looks like, what it does, and how it works.

Biological Causes of Depression. Biological causes of clinical depression continue to be studied extensively. Great progress has been made in the understanding of brain function, the influence of neurotransmitters and hormones, and other biological processes, as well as how they may relate to the development of depression.

7. The strength of an impulse is constant; it is always the same. How, then, do we differentiate between strong or weak stimuli? Strong stimuli activate more sensory neurons and are perceived as “stronger” even though each neuron is stimulated at the same level.Weak stimuli do not activate as many sensory neurons, and are therefore, perceived as weak.
