neurotransmitters
Synapse is a narrow gap containing communicating junction between two neurons where an axon terminal comes near contact with dendrite terminal of next neuron. A narrow fluid filled space, called synaptic cleft, occurs between the two.As the impulse reaches the presynaptic knob, it stimulates release of neurotransmitter into the cleft.
After the action potential reaches the presynaptic terminal, voltage-gated calcium channels open, leading to an influx of calcium ions. This triggers the release of neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the postsynaptic membrane, leading to depolarization and the generation of a new action potential in the postsynaptic neuron.
Stress is caused by chemicals (e.g. cortisol) and therefore, anything that affects the production of these chemicals, affects stress. However, psychological factors affect the production of these chemicals as well.
Yes, when you are in love, your pupils can dilate or get bigger as a result of the release of certain chemicals in the brain, like dopamine and oxytocin. This physiological response is often associated with feelings of attraction and excitement.
Phenylethylamine is a naturally occurring compound that acts as a neurotransmitter in the brain. It can elevate mood by increasing the release of dopamine and serotonin, which are chemicals associated with feelings of pleasure and well-being. This increase in neurotransmitter activity can result in improved mood and feelings of happiness.
Terminal buttons release neurotransmitters, which are chemical messengers that relay signals to nearby neurons across the synaptic gap. The neurotransmitters are stored in vesicles within the terminal buttons and are released in response to an action potential.
A neuron (nerve cell) receives dendritic input in order to generate action potentials to transmit signals of the same. After the action potential triggers release of neurotransmitters in the axonal terminal of that neuron, those neurotransmitters propagate the signal forward to the next neuron, and so forth.
The presynaptic cell that must have action potentials to produce one or more action potentials in the postsynaptic cell is the neuron releasing neurotransmitters at the synapse. When an action potential reaches the presynaptic terminal, it triggers the release of neurotransmitters into the synaptic cleft, which then bind to receptors on the postsynaptic cell membrane, leading to the generation of an action potential in the postsynaptic cell.
The tiny sacs in the synaptic knob are known as synaptic vessels. The synaptic vessels release chemicals into the bloodstream with each synapse.
The part of the neuron where neurotransmitters are released from is the axon terminal, and they are released into a small space between neurons called the Synapse.
This is a structure found in skeletal muscle cells known as a triad. It consists of two terminal cisternae (enlarged regions of the sarcoplasmic reticulum that store and release calcium ions) and a T-tubule (invagination of the sarcolemma that helps transmit action potentials deep into the muscle cell). The triad plays a crucial role in excitation-contraction coupling, where the action potential triggers the release of calcium ions for muscle contraction.
