Where is neurotransmitter stored?
Neurotransmitters are stored in synaptic vesicles in the terminal bouton of pre-synaptic axons. They are released from the terminal bouton into the synaptic cleft and the neurotransmitters exert their action on the post-synaptic neurons.
Which area would contain an abundance of vesicles containing neurotransmitter?
Neurotransmitters are stored in synaptic vesicles within axonal terminals for release into the synaptic cleft.
What functions as a neurotransmitter?
When impulses reach a synapse they trigger the release of chemicals called neurotransmitters. Molecules of the neurotransmitter cross the synapse and stimulate the receiving neuron to fire an impulse of its own as wave like movements of ions. They may also actively inhibit a receiving neuron from firing.
What is the neurotransmitter that is released into the synaptic cleft?
Vesicles containing the neurotransmitters are caused to fuse with the neuron's cell membrane, which thereby presents the neurotransmitters to the outside of the neuron, into the synapse.As I'm sure you know a neurotransmitter is how two neurons communicate at a synapse. It can be one of many molecules, often nor-epinephrine/nor-adrenaline. Neurotransmitters are stored in structures called vesicles in a bulb at the end of the axon the presynaptic neuron. These vesicles are like balloons containing the neurotransmitters, what would be the rubber of the balloon is actually made of the same plasma membrane that surrounds the rest of the cell. When the Action Potential (AP) coming down the axon gets to the bulb it causes Ca ion channels to open. These channels are membrane bound proteins ant act as voltage gated channels in the same way the Sodium ion channels in the axon do. The opening of these channels allows calcium entry into the cells. There are another class of membrane bound proteins that are important here, the Docking proteins. Ca ions activate the docking proteins by binding to them. What these proteins do is effectively grab the vesicles, containing the neurotransmitter, and make the membrane merge with the cells membrane. This is exactly like the opposite of phagocytosis, the cell then secretes the neurotransmitter into the synaptic cleft.The neurotransmitter must then & isreleased from the receptor site, in order to prevent continuing and constant over-stimulation of the post-synaptic neuron. It can be carried back to the presynaptic neuron for either repackaging into vesicles or broken down there by enzymes, or some neuropeptide neurotransmitters simply diffuse away into the surrounding medium, and one (acetylcholine) is broken down right in the synaptic cleft.
In which part are sperm cells produced and stored?
In seminal vesicles of testes

Where are neurotransmitters synthesized and stored?
vesicles.
What substance is found in synaptic vesicles of the axon terminal?
Neurotransmitters are special chemicals that are produced and stored in synaptic vesicles. There are many different kinds and each vesicle can hold hundreds of them. When they are released, they cross the synaptic cleft and attach to a receptor site which may be on another nerve cell, a muscle cell, or a gland.
What is the functions of neurotransmitter?
The neurotransmitters are stored in tiny sac-like structures called vesicles at the end of axons. When an impulse, or nerve signal, reaches the end of the axon, the vesicles release a neurotransmitter into the small space between the adjoining cells (synaptic gap). Neurotransmitters diffuse across the synapse and bind to receptors in the receiving cell that are specific for the neurotransmitter.
Where the neurotransmitter released?
Neurotransmitter are means by which neurons communicate with one another.There are more than 30 compounds known to be neurotransmitters, and dozens of others are thought to be so.Synapses contain synaptic vesicles and other organelles such as mitochondria.Chemical neurotransmitters are manufactured by neurons in the soma, then stored in little bundlescalled synaptic vesicles and transferred to the synapses.
Are neurotransmitters stored within motor neuron endings?
False. Nodes of Ranvier are sections along a mylenated axon that are not mylenated. Instead they contain numerous voltage gated Na and K channels. These channels help transmit the chemical depolarization along the axon until it reaches the synaptic node. Neurotransmitters are stored in synaptic vessicles in the synpatic node.
What event occurs during synapsis?
A synapse is a gap between one neuron and another. To communicate, a neurotransmitter has to be made and then used as a tool to stimulate the second neuron.Synapses contain synaptic vesicles and other organelles such as the mitochondria.Chemical neurotransmitters are manufactured by neurons in the main part of the cell, then stored in little bundles called synaptic vesicles and transferred to the synapses. They are then released into the space between the two neurons.One type of neurotransmitter may stimulate and another type may be the opposite.
What functions as a neurotransmitter?
When impulses reach a synapse they trigger the release of chemicals called neurotransmitters. Molecules of the neurotransmitter cross the synapse and stimulate the receiving neuron to fire an impulse of its own as wave like movements of ions. They may also actively inhibit a receiving neuron from firing.
What is the secretory zone of neuron?
The secretory zone of a neuron refers to the region where neurotransmitters are synthesized, stored, and released. It includes the synaptic vesicles that contain the neurotransmitters and the presynaptic terminal where they are released into the synaptic cleft. This zone plays a crucial role in transmitting signals between neurons and facilitating communication in the nervous system.
Which ion causes neurotransmitters vesicles to fuse with the axons membrane during the conduction of a nerve impulse from one to the next?
Calcium ions cause the neurotransmitter vesicles to fuse with the axon terminal. When an action potential reaches the axon terminal, voltage-gated calcium ion pores are opened, allowing calcium ions into the axon terminal. These ions initiate the release of neurotransmitter vesicles stored on elements of the cytoskeleton located near the presynaptic membrane; they then travel to the presynaptic membrane, where they first dock, and then fuse with the presynaptic membrane, forming an opening or pore through which the neurotransmitters are released into the synaptic cleft.
Why is it that the electrical impulse cannot pass from neuron the muscle cell?
There is a space (synapsis) between the neuron and the muscle cell. The electrical impulse can not pass over that. Chemical neurotransmitters are manufactured by neurons in the soma, then stored in little bundles called synaptic vesicles and transferred to the synapses. The release of the neurotransmitter is required for a nerve to simulate the muscle. This is what crosses the space.
