What is the absorption of a neurotransmitter after it has transmitted a neural impulse called?
The absorption of a neurotransmitter after it has transmitted a neural impulse is called "reuptake." During reuptake, neurotransmitters are taken back into the presynaptic neuron, where they can be recycled and repackaged for future use. This process helps terminate the signal between neurons and regulates the levels of neurotransmitters in the synaptic cleft.
What houses neurotransmitters before release?
Neurotransmitters are housed in synaptic vesicles within the presynaptic terminal of neurons. These vesicles store the neurotransmitters until an action potential triggers their release into the synaptic cleft. The process involves the fusion of the vesicles with the presynaptic membrane, allowing neurotransmitters to be released and transmit signals to the postsynaptic neuron.
What part of neuron facilitate synaptic tranmissionof signal to anather neuron?
The part of the neuron that facilitates synaptic transmission to another neuron is the axon terminal, also known as the synaptic terminal. When an action potential reaches the axon terminal, it triggers the release of neurotransmitters from synaptic vesicles into the synaptic cleft. These neurotransmitters then bind to receptors on the postsynaptic neuron's membrane, allowing the signal to be transmitted. This process is essential for communication between neurons in the nervous system.
What is the result of sodium ions moving across the axons membrane during an action potential?
a neural impulse(electrical impulse) is released and it travels down the axon of a neuron to the axon terminals. At the axon terminal there are sacs called synaptic vesicles which contain chemicals called neurotransmitters. When the neural impulse reaches the terminal it causes the sacs to move closer to the membrane of the axon terminal and release the neurotransmitters inside. Then neurotransmitters travel across the synaptic gap and stimulate the dendrites of another neuron and the whole process starts again.
What is a process whereby one neuron communicates with another neuron?
When nerve impulses are triggered near the soma/cell body, an electrical current known as the ACTION POTENTIAL sweeps through the axon and into the axon terminal. When the action potential reaches the tips of the axon terminal, it causes the synaptic vesicles to move towards the membrane of the terminal buttons. The buttons then open up and release the neurotransmitters (drugs.) The neurotransmitter molecules cross over the synaptic gap and attach themselves unto the receptor sites of the other neuron. After accomplishing their work on the receptor sites, some of the neurotransmitter molecules are broken down into other chemicals in a process called Degradation. The rest of the neurotransmitter molecules are taken up by the vesicles for reuse in a process called Reuptake.
What is the process by which neurotransmitters reenter terminal buttons and are repackaged for future use in the terminal buttons?

What is a presynaptic terminal?
A presynaptic terminal is the part of a neuron that releases neurotransmitters into the synaptic cleft during neurotransmission. Located at the end of an axon, it contains synaptic vesicles filled with these chemical messengers. When an action potential reaches the presynaptic terminal, it triggers the release of neurotransmitters, which then bind to receptors on the postsynaptic neuron, facilitating communication between neurons. This process is essential for the functioning of the nervous system.
How does the signal at the synapse turn off?
The signal at the synapse is turned off primarily through the reuptake of neurotransmitters by the presynaptic neuron, where they are repackaged into vesicles or broken down by enzymes. Additionally, neurotransmitters can diffuse away from the synaptic cleft, reducing their concentration and effect. Some neurotransmitters are also inactivated by specific enzymes in the synapse, further ensuring that the signal ceases. This coordinated process allows for precise control over synaptic transmission and neural signaling.

What are retrograde neurotransmitters?
Retrograde neurotransmitters are released from dendrites and alter the activity of neighbouring cells. This process is the opposite of typical neurotransmitters, which are released from the axon terminal (of a post synaptic neuron) and act on dendrites. Two examples are the gaseous neurotransmitters Carbon Monoxide and Nitric Oxide.

What is a Unused neurotransmitters are absorbed in a process?
Unused neurotransmitters are absorbed through a process called reuptake, where they are taken back up into the presynaptic neuron that released them. This allows for the efficient recycling of neurotransmitters and helps to regulate the levels of neurotransmitters in the synaptic cleft.
What are the three parts of the synapse and what are their functions?
The three parts of a synapse are the presynaptic terminal, the synaptic cleft, and the postsynaptic membrane. The presynaptic terminal releases neurotransmitters into the synaptic cleft, which is the gap between the two neurons. These neurotransmitters then bind to receptors on the postsynaptic membrane, leading to changes in the postsynaptic neuron's activity. This process enables communication between neurons and is essential for transmitting signals throughout the nervous system.
What is the structure at the end of an axon that produces neurotransmitters?
The axon is a single process extending from the axon hillock, sometimes covered by a fatty layer called a myelin sheath that conducts nerve impulses away from the cell body of the neuron.Distal tips of axons are telodendria, each of which terminates in a synaptic knob.
