Neurotransmission mechanism and functions

Neurotransmission is the process of message transfer between neurons, occurring chemically across synapses and electrically within neurons. Key components include dendrites, axons, terminals, and the cell body, each playing a role in receiving and transmitting neurotransmitters. Various substances like dopamine, ephedrine, and benzadrine can influence neurotransmitter levels and subsequently affect behavior and health.
Neurotransmission mechanism and functions
- 1. Neurotransmission: The process of passing messages between neurons.
- 2. Three Rules of Neurotransmission • Messages pass CHEMICALLY between neurons, ELECTRICALLY within each neuron. • Neurons cannot touch each other. • Each neuron has thousands of neurotransmitters waiting to cross the synapse.
- 3. Dendrites: the narrow, branchlike parts that receive incoming neurotransmitters. Terminals: the places where neurotransmitters wait to cross the synapse. Axon: the long, narrow part connecting the cell body to the terminals. Cell body: the part of the neuron that contains the nucleus. Synapse: the gap or empty space surrounding the neuron.
