Nerve impulses are collected from neighbouring neurons through branched extensions or 'dendrites'. They enter the neuronal cell body for processing and are then propagated along... travel at definite rates along axons which split or 'bifurcate' into thousands of branches which terminate as 'axon terminals' also known as 'synaptic knobs' and 'synaptic buttons'. Axon terminals connect with dendrites of neigbouring neurons at specialized points of contact known as 'neural junctions', 'synaptic junctions' or 'synapses'.

What accomplishes the transmission of the nerve signal across the synapse?

The release of 'neurotransmitter substances' from an axon's perifery which traverse the synaptic cleft - the space between axon and adjoining dendrite - to both affect and effect the adjoining dendritic "perifery" which then re-initiates signal propagation to the next bunch of exonic nerve "endings".


The signal to excite a muscle cell must cross the neuromuscular junction by the diffusion of acetylcholine across the?

The signal to excite a muscle cell involves the release of acetylcholine from the motor neuron into the synaptic cleft at the neuromuscular junction. Acetylcholine diffuses across the synaptic cleft and binds to receptors on the muscle cell membrane, leading to depolarization and muscle contraction. This process is crucial for transmitting signals from the nervous system to the muscle for movement.


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.


The transport mechanism for a neurotransmitter across the synaptic cleft is called?

The transport mechanism for a neurotransmitter across the synaptic cleft is called exocytosis. During exocytosis, neurotransmitter-filled vesicles fuse with the presynaptic membrane, releasing the neurotransmitter into the synaptic cleft where it can then bind to receptors on the postsynaptic membrane.


What is the gap between a neuron and its effector?

The gap between a neuron and its effector is called a synaptic cleft. Neurotransmitters are released from the neuron into this gap and then bind to receptors on the effector cell to transmit the signal.

Can neurotransmitters cross the synaptic cleft?

Yes, neurotransmitters diffuse across the synaptic cleft to transmit a neural signal; the actual neural impulse(spike) occurs when the neuron fires in response to a sufficiency of signals received.

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 the substance released into the synaptic cleft?

Neurotransmitters are the substances released into the synaptic cleft. They are chemical messengers that transmit signals across the synapse from one neuron to another.


What is the gap between a neuron and its effector?

The gap between a neuron and its effector is called a synaptic cleft. Neurotransmitters are released from the neuron into this gap and then bind to receptors on the effector cell to transmit the signal.


What is a presynaptic neuron?

a neuron from the axon terminal of which an electrical impulse is transmitted across a synaptic cleft to the cell body or one or more dendrites of a postsynaptic neuron by the release of a chemical neurotransmitter.


What reactions leap across synapses?

Reactions don't leap across synapses but neurotransmitters will diffuse across the synaptic cleft.


What is Diffusion of transmitters across synaptic cleft?

Diffusion of transmitters across synaptic cleft is the process by which neurotransmitters are released from the presynaptic neuron into the synaptic cleft and then bind to receptors on the postsynaptic neuron. This allows for the transmission of signals from one neuron to another in the nervous system.
