Neurotransmitter are means by which neurons communicate with one another. There are more than 30 compounds known to be neurotransmitters, and dozens of others are thought to be so.

The are sack-like structures found inside the synaptic knob containing chemicals?
synaptic vesicles
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.
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!
What does not belong axon terminal synaptic knob bouton axon collateral?
axon collateral
What is the function of synaptic knob of axon terminal?
"When a nerve impulse reaches the synaptic knob at the end of an axon, synaptic vesicles release a neurotransmitter that diffuses across the synaptic cleft and binds to specific receptors on the postsyanptic membrane" Above From:Hole's essentials of Human Anatomy & Physiology (tenth edition) page=220, figure9.9 Quick definition of the "Synaptic knob- Tiny enlargement at the end of an axon that secretes a neurotransmitter." Above From: Same book as before (Hole's essentials of Human...) page= 584 (Glossary)

What is the terminal buttom?
the sack like structures found inside the synaptic knob containing chemicals are called what?
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.
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!
Chemicals found in the synaptic vesicles which when released has an effect on the next cell?
a neurotransmitter
What are The chemicals that bridge the synaptic gap?
Chemicals that bridge the synaptic gap are called neurotransmitters.
What is released from an axonal nerve ending?
Chemicals called neurotransmitters are employed in the relay, amplification, and modulation of electrical impulses between neuronal cells. Vesicles found at the pre-synaptic knob of axon terminals discharge them.
When an action potential passes over the surface of synaptic knob the contents of vesicles is released in the presence of?
exocitocisThey dir
What happens after nerve signal reaches a synaptic knob?
In general, action potentials that reach the synaptic knobs cause a neurotransmitter to be released into the synaptic cleft. The arrival of the action potential opens voltage-sensitive calcium channels in the presynaptic membrane.
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 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 .
