The synaptic terminal of a sensory nueron is located where?
the bulb on the end of an axon
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 the difference between the axon and axonal terminal and synaptic knob?
Axon is branch of neuron that conducts impulse , axonal terminal and synaptic knob are same , it is bulb like and makes a synapse .
What susbstance is found in synaptic vesicles of axon terminal?
Neurotransmiter, which may be Acetylcholine etc
What substance is found in synaptic vesicles of the axon terminal what role does it play in neurotransmissions?
Acethylcholine
Synaptic vesicles are found in what?
Synaptic vesicles are found in the axon terminals of nerve cells.
The are sack-like structures found inside the synaptic knob containing chemicals?
synaptic vesicles
The synaptic terminal of a sensory nueron is located where?
the bulb on the end of an axon
What causes calcium ions to enter the synaptic bulb?
The nerve signal arrives at a synaptic knob and causes calcium channels to open. This allows the calcium ions to enter the synaptic knob. Calcium ions entry into the synaptic knob triggers exocytosis of synaptic vesicles, which release acetylcholine into the synaptic cleft.

What are the tiny sacs found within the terminal button which release chemicals into the synapse?
The tiny sacs in the synaptic knob are known as synaptic vessels. The synaptic vessels release chemicals into the bloodstream with each synapse.

What susbstance is found in synaptic vesicles of axon terminal?
Neurotransmiter, which may be Acetylcholine etc
Chemicals found in the synaptic vesicles which when released has an effect on the next cell?
a neurotransmitter
What substance is found in synaptic vesicles of the axon terminal what role does it play in neurotransmissions?
Acethylcholine
What is synaptic potential?
synaptic potential
What is the terminal buttom?
the sack like structures found inside the synaptic knob containing chemicals are called what?
