What is the term used to describe the rounded areas on the ends of the axon terminals?
The term used to describe the rounded areas on the ends of the axon terminals is "synaptic end bulbs" or "synaptic boutons". These structures contain neurotransmitters that are released into the synapse to communicate with the next neuron.
Axons terminate in a series of fine extensions known as?
Axon terminals, also known as synaptic boutons or end bulbs, are the fine extensions at the end of an axon that transmit signals to other neurons or effector cells. These terminals contain neurotransmitters that are released into the synaptic cleft to communicate with the target cell.
What is at the end of an axon terminal branch?
At the end of an axon terminal branch, you will find structures called synaptic boutons or synaptic terminals. These structures contain neurotransmitter vesicles that store and release neurotransmitters into the synaptic cleft to communicate with the next neuron or target cell.
Neurotransmitters are released from what end of an axon?
synaptic vesicles
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
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.
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.

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 a synaptic knob b motor end plate c neuromuscular junction d synaptic cleft e transverse tubule contains vesicles filled with acetylcholine?
c) neuromuscular junction, d) synaptic cleft.
What are axon terminal clusters at the ends of neuromuscular junctions called?
Axon terminal clusters at the ends of neuromuscular junctions are called motor endplates. They are specialized structures where motor neurons communicate with muscle fibers to initiate muscle contractions.
