Why doesn't acetylcholine remain on the post-synaptic process?
Acetylcholine (ACh) does not remain on the post-synaptic membrane because it is rapidly broken down by the enzyme acetylcholinesterase. This enzymatic degradation occurs in the synaptic cleft, preventing prolonged stimulation of the post-synaptic receptors. Additionally, the reuptake of choline into the pre-synaptic neuron helps recycle components for future neurotransmitter synthesis. This process ensures that synaptic transmission is brief and precisely regulated.
What are different types of cells that are post-synaptic?
Post-synaptic cells can vary widely depending on their location and function in the nervous system. Common types include neurons, which can receive signals from other neurons, and glial cells, such as astrocytes, which can modulate synaptic activity and support neuronal function. Additionally, muscle cells (myocytes) can serve as post-synaptic targets in neuromuscular junctions, responding to signals from motor neurons. Each type plays a distinct role in processing and responding to neurotransmitter signals.
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 causes the synaptic delay?
The cause of synaptic delay is attributed mainly to the time needed for the synaptic vesicles to release neurotransmitter into the synaptic cleft. While it can be considered a combination of binding to the presynaptic membrane (which is relatively a transient process) and subsequent exocytosis of the neurotransmitter, the main factor is release. Additionally, it does take a very short period of time for the neurotransmitter to diffuse across the synaptic cleft and bind to to its receptors on the post-synaptic membrane.
What is synaptic terminal?
Cells that help create and assist the function of synapse's. In layman's terms brain cells.
What is accomplished by synaptic transmission?
Synaptic transmission, also called neurotransmission, refers to the process wherein neurotransmitters are released by a neuron to activate the receptors of another neuron. Communication between two nerve cells is accomplished by synaptic transmission.
Synaptic vesicles are found in what?
Synaptic vesicles are found in the axon terminals of nerve cells.
A synaptic knob would be located on a?
A synaptic knob is a tiny bulge at the end of a terminal branch of a presynaptic neuron's axon!
How does synaptic pruning in adolescence impact brain development and cognitive function?
Synaptic pruning in adolescence is a process where unnecessary connections between neurons are eliminated, allowing the brain to become more efficient. This process helps strengthen important connections and improve cognitive function by enhancing the brain's ability to process information and adapt to new experiences.

Does synaptic transmission involve electrical information to pass from terminal button to dendrites of another neuron?
No, synaptic transmission is chemical, not electrical.
What function does synaptic vesicles containing neurotransmitter?
Synaptic vesicles containing neurotransmitters play a crucial role in communication between neurons. They release neurotransmitters into the synaptic cleft, where they bind to receptors on the receiving neuron, leading to signal transmission. This process allows for the relay of information within the nervous system.

Where is the synaptic bulb found?
The synaptic bulb is found at the end of axon terminals in neurons. It is the structure responsible for releasing neurotransmitters to communicate with other neurons or target cells at a synapse.
