WebFenfluramine is an amphetamine derivative drug that was once widely prescribed as an appetite suppressant to treat obesity. Fenfluramine is devoid of the psychomotor stimulant and abuse potential of D-amphetamine and interacts with certain 5 -hydroxy tryptamine (serotonin, 5-HT) receptors and the serotonin transporter to release 5-HT from neurons. Web6 sep. 2024 · The axon is a long, thin structure that transmits information to other cells. The structure of a neuron allows it to transmit nerve impulses quickly and effectively. When a stimulus, such as a touch or a sound, enters one of the dendrites, it triggers an electrical signal in the cell body.

WebTowards the end of Axon’s are synaptic end bulbs these consist of vesicles which store neurotransmitters, special chemicals that are released during communication between neurones, so during a muscle contraction Synaptic end bulb would release the Acetylcholine which assists within the transmitting of the signal, and the Bulb would also produce the …
