Synaptic events refer to the processes involved in communication between neurons at synapses. These events include neurotransmitter release from the presynaptic neuron, binding of neurotransmitters to receptors on the postsynaptic neuron, and subsequent changes in the postsynaptic neuron's membrane potential. This can lead to excitation or inhibition of the postsynaptic neuron based on the type of neurotransmitter and receptors involved.

What causes the synaptic delay?
The synaptic delay is caused by the process of neurotransmitter release, diffusion across the synaptic cleft, binding to receptors on the post-synaptic neuron, and the propagation of the electrical signal through the post-synaptic cell. This series of events takes time to occur, leading to the delay in signal transmission across the synapse.
The narrow space between the synaptic terminal and the muscle fiber is the?
synaptic cleft, where neurotransmitters are released by the synaptic terminal and bind to receptors on the muscle fiber to trigger a muscle contraction.
What are The chemicals that bridge the synaptic gap?
Chemicals that bridge the synaptic gap are called neurotransmitters.
What is Synaptic capacity?
Synaptic capacity refers to the maximum number of synaptic connections that can be formed between neurons in the brain. It is a measure of the brain's ability to adapt, learn, and store information. Increases in synaptic capacity are associated with learning and memory formation.
What is the difference between action potentials and synaptic potentials?
Action potentials are brief electrical events that occur in neurons, allowing for communication over long distances. In contrast, synaptic potentials are changes in voltage that occur at the synapse between two neurons, facilitating communication between them. While action potentials are all-or-nothing responses, synaptic potentials can be excitatory or inhibitory.

What is the normal sequence of events that occur during synaptic transmission at a motor end plate?
1. Nerve impulse reaches synaptic terminal. 2. Synaptic vesicles move to and merge with the presynaptic cell membrane of the motor neuron. 3. Acetylcholine is released into and diffuses across the synaptic cleft. 4. Acetylcholine binds to receptors on the postsynaptic cell membrane of the muscle fiber.
The are sack-like structures found inside the synaptic knob containing chemicals?
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.
What is the small space separating pre and post-synaptic neurons?
The small space separating pre and post-synaptic neurons is called the synaptic cleft. This cleft allows for the transmission of chemical signals, known as neurotransmitters, from the pre-synaptic neuron to the post-synaptic neuron to occur. The neurotransmitters are released by the pre-synaptic neuron and bind to receptors on the post-synaptic neuron to transmit the signal.
Is synaptic transmission always from pre to post synaptic?
Yes
What are synaptic gaps?
Synaptic gaps are the spaces between neurons.
The narrow space between the synaptic terminal and the muscle fiber is the?
synaptic cleft, where neurotransmitters are released by the synaptic terminal and bind to receptors on the muscle fiber to trigger a muscle contraction.
What are the principles of synaptic transmission?
Calcium ions enter the presynaptic neuron resulting in the release of neurotransmitter from the per-synaptic membrane. The neurotransmitter diffuses across the synaptic cleft, fusing with the receptors of the post-synaptic membrane. This changes the sodium channels to open and sodium ions will to flow into the post-synaptic neuron, depolarizing the post-synaptic membrane. This initiates an action potential. After the post-synaptic neuron has been affected, the neurotransmitter is removed by a type of enzyme called cholinesterase. The inactivated neurotransmitter then returns to the pre-synaptic neuron.
When was Synaptic - software - created?
Synaptic - software - was created on 2001-11-13.
What does the word synaptic mean?
The word synaptic is an adjective which means, pertaining to the synapses. So, I could describe dopamine as a chemical that has a synaptic function, as a neurotransmitter.
What are the tiny sacs found within the terminal button which release chemicals into the synapse?
The tiny sacs are called synaptic vesicles. They contain neurotransmitters that are released into the synapse in response to an action potential arriving at the terminal button.
The tiny space between the axon terminal and the dendrite of another neuron is called the?
Synaptic Cleft.
