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'.

∙ 13y agoThe neurotransmitter is released in vessicles from the axon of one neuron to the dendrite of another neuron, or directly onto the target organ.

The signal to excite a muscle cell must cross the neuromuscular junction by the diffusion of acetylcholine across the?
synaptic cleft
What is the Process by which ACh gets across cleft?
The transport process by which ACh is released into the synaptic cleft is called Exocytosis.
How do electrical impulses go across synapses?
An electrial nerve impulse travels across a synapse by diffusion. The neurotransmitter substance from the pre-synaptic cleft travels across the synapse via diffusion. This is then received by receptors in the post synaptic cleft
The transport mechanism for a neurotransmitter across the synaptic cleft is called?
simple diffusion
What is the opening across which one neuron communicates with another neuron known as?
Synaptic cleft
The signal to excite a muscle cell must cross the neuromuscular junction by the diffusion of acetylcholine across the?
synaptic cleft
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 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 is a true statement about synapses?
The synaptic cleft prevents an impulse from being transmitted directly from one neuron to another.
What reactions leap across synapses?
Reactions don't leap across synapses but neurotransmitters will diffuse across the synaptic cleft.
What is the opening across which one neuron communicates with another neuron known as?
Synaptic cleft
The tiny space between the axon terminal and the dendrite of another neuron is called the?
Synaptic Cleft.
Where do nerve impulses leave the neuron?
Nerve impulses are transmitted down the axon and leave the neuron via the terminal bouton at the synaptic interface, releasing neurotransmitters into the synaptic cleft to affect the post-synaptic cell..
What is the space between neurons across which chemical messages pass?
The space between neurons is called the synaptic cleft. It is where neurotransmitters are released by the presynaptic neuron, travel across the cleft, and bind to receptors on the postsynaptic neuron to transmit chemical messages.
