what are the different parts of a synapse?
480538
There are essentially 3 parts to a synapse: the presynaptic neuron, the synaptic cleft, and the postsynaptic neuron. There are two kinds of synapses in the nervous system: electrical and chemical.

Most synapses are chemical; these synapses communicate using chemical messengers. Other synapses are electrical; in these synapses, ions flow directly between cells. At a chemical synapse, an action potential triggers the presynaptic neuron to release neurotransmitters.

The three main parts of an eukaryotic cell include: an outer boundary (plasma membrane), an interior substance (cytoplasm), and a control region (nucleus).

Synaptic knobs are located on a neuron's axon. The axon can be very long and have many synaptic knobs.

In a neuron, synaptic vesicles (or neurotransmitter vesicles) store various neurotransmitters that are released at the synapse. The release is regulated by a voltage-dependent calcium channel. Vesicles are essential for propagating nerve impulses between neurons and are constantly recreated by the cell.

The synapse is the junction between two neurons and the synaptic cleft is the distance between the pre-synaptic neuron's axon tip and post-synaptic neuron's dendrite tip. They both don't actually touch and the distance between them is that.

The axon terminal is half of a synapse. A synapse is the connecting structure between two neurons. It includes the axon terminal (the “presynaptic bouton”), the synaptic cleft (a tiny gap), and the dendritic terminal or dendritic spine (the “postsynaptic bouton”).

Neurons send signals to other neurons via specialized contacts known as synapses. The most common type of synapse in the nervous system is known as a chemical synapse. Typically a chemical synapse occurs between the axon terminal of the neuron sending the message, and the dendrite of the neuron receiving the message.

Synapsis (also called syndesis) is the pairing of two homologous chromosomes that occurs during meiosis. It allows matching-up of homologous pairs prior to their segregation, and possible chromosomal crossover between them. ... Mitosis also has prophase, but does not ordinarily do pairing of two homologous chromosomes.

Synapses can be thought of as converting an electrical signal (the action potential) into a chemical signal in the form of neurotransmitter release, and then, upon binding of the transmitter to the postsynaptic receptor, switching the signal back again into an electrical form, as charged ions flow into or out of the ...
