The function of a neuron is to transmit information within the nervous system.Neural transmissionoccurs when a neuron is activated, or fired (sends out an electrical impulse). Activation (firing) of the neuron takes place when the neuron is stimulated by pressure, heat, light, or chemical infor...
Define Synaptic transmission. Synaptic transmission synonyms, Synaptic transmission pronunciation, Synaptic transmission translation, English dictionary definition of Synaptic transmission. n. the transmission of a nerve impulse across a synapse. Random
a specialized, impulse-conducting cell that is the functional unit of the nervous system, consisting of the cell body and its processes, the axon and dendrites. Also callednerve cell.Also,esp. Brit.,neu•rone(-oʊn) [1880–85; < Greekneûronsinew, cord, nerve] ...
The post-fibre is, in each case, the largest of the motor axons which leave the ganglion in the third root. Fig. 1 shows an example of nerve-impulse transmission across such a synapse. The pre-junctional axon was stimulated with external electrodes; and its action potential, recorded intra...
(or nerve cell), the basic structural and functional unit of the nervous system. A neuron receives signals that enter from receptors and other neurons and processes and transmits the signals in the form of nerve impulses to the effector nerve endings, which control the activities of the corresp...
Eugenol depresses the neuromuscular transmission (Ozeki, 1975) and the central nervous system function (Dallmeier and Carlini, 1981). Eugenol depresses synaptic transmission but does not prevent the induction of long-term potentiation in the CA1 region of rat hippocampal slices High doses of [Mg....
2. The conveyance of disease from one person to another. 3. The passage of a nerve impulse across an anatomic cleft, as in autonomic or central nervous system synapses and at neuromuscular junctions, by activation of a specific chemical mediator that stimulates or inhibits the structure across...
Fast Synaptic Transmission and Neuromodulation in the Central Nervous System The majority of connections that make up aneural networkin the mammaliancentral nervous systemare synaptic connections in which aneurotransmitterreleased from the presynaptic neuron activatespostsynaptic receptorsthat are neurotransmitter...
Neuromodulatory transmission broadly controls neural circuits and behavior. It is exceptionally diverse and includes many different types of transmitters [1,2,3,4,5]. For example, several monoaminergic systems and many neuropeptides regulate nervous system function. Disruption or dysfunction of modulatory...
On the other hand, a neurobiological model established in the recent decades, has supported the notion that an important mechanism of acupuncture in curing diseases is mediated by the nervous system. Stimulation by needles at acupoints is considered to initiate acupuncture signals through the nerve ...
