What else can I help you with?
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.
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.
What are highly branched cellular processes of a neuron that carry signals towards the cell body of a neuron?
These are called dendrites as they look like the branches of trees.It sounds like you're describing a synaptic transmission.
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 space between the sending and the receiving neuron called?
The space between the sending neuron's axon terminal and the receiving neuron's dendrite is called the synaptic cleft. Neurotransmitters are released into this space to transmit signals between neurons.
Why there is gap between two nerve junctions?
The gap between two nerve junctions is called a synaptic cleft. It exists to allow for the transfer of chemical signals, called neurotransmitters, from one neuron to the next. This synaptic cleft ensures that the signals are transmitted in a controlled and precise manner, contributing to the proper functioning of the nervous system.
What are the tiny branches at the end of a motor neurone called?
The tiny branches at the end of a motor neuron are called axon terminals or synaptic terminals. They are responsible for transmitting signals to target cells, such as muscle cells or other neurons, through the release of neurotransmitters at synaptic connections.
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.
Which is the space that separates two neurons?
Synapses
Space between synaptic end bulbs of axon terminal and sarcolemma?
The space between the synaptic end bulbs of an axon terminal and the sarcolemma is called the synaptic cleft. It is a small gap that neurotransmitters traverse to transmit signals between neurons and muscle cells. The neurotransmitters released from the axon terminal bind to receptors on the sarcolemma, triggering muscle contraction.
What is the spce between two neurons where the axon of a sending neuron communicates with the dendrites of a receiving neuron by using chemical messages called?
The space between two neurons where communication occurs using chemical messages is called the synaptic cleft. Neurotransmitters are released from the axon terminal of the sending neuron and bind to receptors on the dendrites of the receiving neuron, facilitating the transmission of signals between the two.
Gamma-aminoburyric acid appears to decrease synaptic transmission and seems related to what drugs?
Gamma-aminobutyric acid is also known as GABA. It appears to decrease synaptic transmission and is actually used in drugs called GABAergic drugs or GABA analogues. These drugs are used as hypnotics, anticonvulsants, tranquillizers and sedatives.
