Neuron Synapse Anatomy Poster Print by Monica Schroeder/Science Source (24 x 36)
(A) Electron micrograph of a human synapse with two synaptic junctions to illustrate the canonical features of all synapses: An intercellular junction in which a presynaptic varicosity that is filled with synaptic vesicles contacts a postsynaptic dendrite that contains multiple trafficking organelles as well as ribosomes (image courtesy of Dr. C.
Introduction to Neurophysiology Physiopedia
At the synapse, the firing of an action potential in one neuron—the presynaptic, or sending, neuron—causes the transmission of a signal to another neuron—the postsynaptic, or receiving, neuron—making the postsynaptic neuron either more or less likely to fire its own action potential.

Neurotransmitters and receptors
Diagram of a synapse, showing neurotransmitters stored in synaptic vesicles inside the axon terminal. In response to an action potential, the vesicles fuse with the presynaptic membrane and release neurotransmitter into the synaptic cleft.

Communication Between Neurons Anatomy and Physiology I
A synapse is a small gap at the end of a neuron that allows a signal to pass from one neuron to the next. Neurons are cells that transmit information between your brain and other parts of the central nervous system. Synapses are found where neurons connect with other neurons.
Synapses Definition, Types and Structure , Anatomy QA
Diagram of a chemical synaptic connection Synapses are functional connections between neurons, or between neurons and other types of cells. [5] [6] A typical neuron gives rise to several thousand synapses, although there are some types that make far fewer. [7]
Pitt Medical Neuroscience Synaptic Transmission
The general structure of a chemical synapse is shown schematically in Figure 5.1B. The space between the pre- and postsynaptic neurons is substantially greater at chemical synapses than at electrical synapses and is called the synaptic cleft. However, the key feature of all chemical synapses is the presence of small, membrane-bounded organelles called synaptic vesicles within the presynaptic.
What Is A Synapse? What Is A Neurotransmitter? How Do They Work?
Resources. For the nervous system to function, neurons must be able to communicate with each other, and they do this through structures called synapses. At the synapse, the terminal of a presynaptic cell comes into close contact with the cell membrane of a postsynaptic neuron. Figure 8.1. The terminal of a presynaptic neuron comes into close.
Neurotransmission
At its simplest, the neuromuscular junction is a type of synapse where neuronal signals from the brain or spinal cord interact with skeletal muscle fibers, causing them to contract. The activation of many muscle fibers together causes muscles to contract, which in turn can produce movement.
What Happens at The Synapse?
The peripheral nervous system ( PNS ), which consists of the neurons and parts of neurons found outside of the CNS, includes sensory neurons and motor neurons. Sensory neurons bring signals into the CNS, and motor neurons carry signals out of the CNS. _Image modified from " Nervous system diagram ," by Medium69 ( CC BY-SA 4.0 )._

Diagram of a chemical synaptic connection. In the nervous system, a synapse [1] is a structure that permits a neuron (or nerve cell) to pass an electrical or chemical signal to another neuron or to the target effector cell.
The Neuron Is the Building Block of the Nervous System
Where two neurons meet there is a small gap called a synapse close synapse A tiny gap at the junction between two nerve cells, which nerve signals must cross..The plasma membranes of each neuron.
Synapses Anatomy and Physiology I
In psychology, a synapse is the junction between two neurons where information is transmitted from one neuron to another. It consists of the axon terminal of the sending neuron, the synaptic cleft (a small gap), and the dendrite or cell body of the receiving neuron.
