Stimulation in Biological Definition

Dendrite

... or " neuron ," which conducts the electrical stimulation received from other cells to the body or soma of the cell from which it projects. This stimulation arrives through synapses , which typically are ... Dendrites were once believed to merely convey stimulation passively, without action potentials and ...

Hormone

... is determined by the pattern of secretion and the signal transduction of the receiving tissue. Hormone actions vary widely, but can include stimulation or inhibition of growth, induction or suppression of apoptosis (programmed cell death), activation or inhibition of the immune system , regulating ...

Insulin

... molecules in the cell membrane which transport glucose into the cell. Two types of tissues are most strongly influenced by insulin as far as the stimulation of glucose uptake is concerned: muscle cells ( myocytes ) and fat cells ( adipocytes ). The former are important because of their central role in ...

Long-term potentiation

... Brain Res. 1978 Nov 24;157(2):277-93. PMID 719524 Murphy GG, Glanzman DL. "Enhancement of sensorimotor connections by conditioning-related stimulation in Aplysia depends upon postsynaptic Ca2+." Proc Natl Acad Sci U S A . 1996 Sep 3;93(18):9931-6. PMID 8790434 ( full text PDF ) Morris RG, ...

Nervous system

... relaxed, and is responsible for such things as the constriction of the pupil, the slowing of the heart, the dilation of the blood vessels, and the stimulation of the digestive and geniturinary systems. Nervous system diversity The nervous system varies greatly among living animals. Cnidarians , such ...

Neuron

... which release the neurotransmitter) may produce in the post-synaptic neurons (i.e. the neurons being affected by the neurotransmitter) an electrical stimulation (an electrical excitation ) which will spread to the axon hillock generating an action potential which then travels as a wave of electrical ...

Proprioception

... despite popular belief, the phantom limb phenomena is actually the result of neural signal bleed through the brain's sensory maps, rather than from stimulation of nerves.) There is one known case of a person losing her entire proprioceptive sense, which is one of the cases discussed in Oliver Sacks ' book ...

Proteome

... is the collection of proteins found in a particular cell type under a particular set of environmental conditions such as exposure to hormone stimulation . It can also be useful to consider an organism's complete proteome . The complete proteome for an organism can be conceptualized as the complete ...

Selective serotonin reuptake inhibitor

... from the receptors and taken up again by monoamine transporters in the sending cell (thus reuptake ). Depression has been linked to a lack of stimulation of the recipient neuron at a synapse. To stimulate the recipient cell, SSRIs inhibit the reuptake of serotonin. As a result, the serotonin stays in ...
