What are axon terminal clusters at the ends of neuromuscular junctions called?
Synaptic end bulbs
The synaptic terminal of a sensory nueron is located where?
the bulb on the end of an axon
Neurotransmitters are released from what end of an axon?
synaptic vesicles
Where is acetycholine found?
It is a neurotransmitter at cholinergic synapses in the central, sympathetic and parasympathetic nervous systems. Abbreviated ACh.acetylcholine receptorsstructures located at the endorgans, e.g. at the skeletal muscle fibers. The myofibers are stimulated to contract by the interaction of acetylcholine with acetylcholine receptors which are located on the motor end plate or postsynaptic sarcolemma.Acetylcholine receptors are gated ion channels that open in response to acetylcholine, leading to an increase in membrane conductance.
What type of ion channel opens on the synaptic end bulb in response to depolarisation?
Calcium (Ca2+) channels open on the synaptic end bulb in response to depolarization (from the action potential), inducing exocytosis of synaptosomes containing neurotransmitter, resulting in neurotransmitter being released into the synaptic cleft...further propagating the signal to the next neuron or set of neurons.
Who do dendrites talk to?
Synaptic End Bulbs
Space between synaptic end bulbs of axon terminal and sarcolemma?
synaptic cleft i think
What is the extensions on the distal end of a neuron called?
The distal end of a neuron is the axon, an extension that arises from the soma (cell body), and at the distal end of an axon there are extensions called telodendria. At the distal ends of telodendria are knoblike structures called synaptic end bulbs (sometimes called synaptic knobs). Synaptic end bulbs have synaptic vesicles inside them that contain neurotransmitters. Synaptic vesicles are released by exocytosis into the synaptic cleft for diffusion. I can't tell from the way your question is worded if you're asking about axons, telodenria or synaptic end bulbs because all of these structures are at the distal end of a neuron. Determine what the function of the "extensions" is and use whichever part of my answer applies.
Which part of the nerve cell ivides into synaptic end-bulbs at neuromuscular junction?
The axon.
What are axon terminal clusters at the ends of neuromuscular junctions called?
Synaptic end bulbs
A synaptic knob would be located on a?
A synaptic knob is a tiny bulge at the end of a terminal branch of a presynaptic neuron's axon!
The synaptic terminal of a sensory nueron is located where?
the bulb on the end of an axon
Neurotransmitters are released from what end of an axon?
synaptic vesicles

Is it the synaptic cleft that contains vesicles filled with acetylcholine?
The synaptic knob contains vesicles filled with neurotransmitters. Therefore, Acetylcholine is the neurotransmitter that stimulates skeletal muscle to contract. It is released into the synaptic clefts between motor neuron axons and motor end plates.
What type of ion channel opens on the synaptic end bulb in response to depolarisation?
Calcium (Ca2+) channels open on the synaptic end bulb in response to depolarization (from the action potential), inducing exocytosis of synaptosomes containing neurotransmitter, resulting in neurotransmitter being released into the synaptic cleft...further propagating the signal to the next neuron or set of neurons.
What is synaptic potential?
synaptic potential
