Synapses are asymmetric both in structure and in how they operate. Only the so-called presynaptic neuron secretes the neurotransmitter, which binds to receptors facing into the synapse from the postsynaptic cell.

synapse The junction between an axon and an adjacent neuron. PICTURE
synapsis The alignment of chromosomes during meiosis I so that each chromosome is beside its homologue.
synapse - a highly specialized junction between two neurons, or between a neuron and an effector cell (e.g., muscle or gland cell), at which electrical and/or chemical signals are passed from one cell to another.
synapse
the locus where one neuron communicates with another neuron in a neural pathway; a narrow gap between a synaptic terminal of an axon and a signal-receiving portion (dendrite or cell body) of another neuron or effector cell.
Synapses can be either chemical or electrical. An electrical synapse is what is often called a "gap junction," in which the membranes of two neurons are continuous at tiny spots, making the cells electrically contiguous.

Are your Synapses Firing?
Remember that the cells making up your nervous system are called neurons. Neurons are connected to other neurons, as well as to other tissues within the body via synapses.
Recombination synapse The initial stage in the recombination process in which four molecules of recombinase and their associated DNA molecules come together.

Ab42 (the 42-amino-acid form of Ab) induces membrane lipid peroxidation in synapses and dendrites resulting in impairment of membrane ion-motive ATPases and glucose and glutamate transporters.
During the prophase of meiosis I, homologous chromosomes pair and form synapses. The paired chromosomes are called bivalents. The bivalent has two chromosomes and four chromatids, with one chromosome coming from each parent.

During prophase I, homologous chromosomes pair and form synapses, a step unique to meiosis. The paired chromosomes are called bivalents, and the formation of chiasmata caused by genetic recombination becomes apparent.
The junction between a nerve cell and another cell is called a synapse. Messages travel within the neuron as an electrical action potential. The space between two cells is known as the synaptic cleft.
Acetylcholine is the chemical transmitter at the parasympathetic synapses. Its function is to stimulate digestion, slow the heart and lower the blood supply to skeletal muscles. The parasympathetic signals a "vegetative" state.
