This chemical is called as neurotransmitter. There are many neurotransmitters, used by nature in synaptic junctions. Some like noradrenaline is taken up by the proximal neuron. Some like acetylcholine are destroyed by the enzyme. Dopamine and serotonin are other common neurotransmitters.
neurotransmitters
The tiny sacs in the synaptic knob are known as synaptic vessels. The synaptic vessels release chemicals into the bloodstream with each synapse.
a neurotransmitter
The sack-like structures inside the synaptic knob containing chemicals are called synaptic vesicles. These vesicles store and release neurotransmitters, which are chemical messengers that transmit signals between neurons. When an action potential reaches the synaptic knob, it triggers the release of neurotransmitters from the synaptic vesicles into the synaptic cleft.
Neurotransmitters are stored in synaptic vesicles located at the terminals of presynaptic neurons. When an action potential reaches the terminal, these vesicles release neurotransmitters into the synaptic cleft to facilitate communication between neurons.
Synaptic vesicles are found in the axon terminals of nerve cells.
acetylcholinesterase
The synaptic bulb is found at the end of axon terminals in neurons. It is the structure responsible for releasing neurotransmitters to communicate with other neurons or target cells at a synapse.
The substance found in synaptic vesicles is usually neurotransmitters such as dopamine, serotonin, or glutamate. These substances are released into the synapse when an action potential reaches the axon terminal, helping transmit signals from one neuron to another across the synaptic cleft.
Neurotransmitters are the substances found in synaptic vesicles of axon terminals. These neurotransmitters are released into the synapse, where they transmit signals from one neuron to another. Some common neurotransmitters include dopamine, serotonin, and acetylcholine.
Synapses occur between two neurons. Electrical activitiy in the pre-synaptic neuron influences the post-synaptic neuron. There are two types of synapses in the body: Electrical and chemical. Electrical synapses occur in pre and post synaptic neurons that are joined via gap junctions. Currents from action potentials flow across the junction through channels called connexons. This current will depolarize the membrane of the post synaptic neuron to threshold, which will continue the action potential in the cell. Electrical synapses are fast and bidirectional. However, they are mainly found in cardiac and smooth muscles, and not in the mammalian nervous system.Chemical synapses use neurotransmitters. Depolarization occurs in the pre-synaptic neuron and calcium ions rush in. The calcium ions activate neurotransmitter release into the synaptic cleft. The neurotransmitters reach the post-synaptic neuron and cause action potentials to develop.Note: this can go into much more detail
