What Is A Synapse? What Is A Neurotransmitter? How Do They Work?
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 Anatomy and Physiology I
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.
Pitt Medical Neuroscience Synaptic Transmission
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.
Introduction to Neurophysiology Physiopedia
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]
Microglia Maintenance of Neuron Synapses
Mechanism of Synaptic Transmission 3. Properties. Definition of Synapse: Synapse can be defined as functional junction between parts of two different neurons. There is no anatomical continuity between two neurons involved in the formation of synapse.
Neuronal Synapses Synaptic Transmission in the Nervous System The Nervous System Medical
synapse, the site of transmission of electric nerve impulses between two nerve cells (neurons) or between a neuron and a gland or muscle cell (effector). A synaptic connection between a neuron and a muscle cell is called a neuromuscular junction.
Chemical and Electrical Synapses Biology for Majors II
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.
Communication Between Neurons Anatomy and Physiology I
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.

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 )._

Types Synapses are fundamentally classified into two different types based on how the neurons function to communicate: 1) chemical synapse and 2) electrical synapse. 1) Chemical Synapse Found in vertebrates, it works using neurotransmitters that establish the virtual connection between the presynaptic and postsynaptic neurons.

Neurotransmission
Synapse diagram Each neuron forms about 2,000 synapses. There are about 10 11 neurons in the CNS. The synapses are of different types and can be classified on the following bases. Parts of neurons involved in the synapse Axodendritic synapse- The axon of the presynaptic neuron connects to the dendrite of the postsynaptic neuron.
Neurotransmitters and receptors
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.
