What is the Process by which ACh gets across cleft?
Acetylcholine (ACh) is released from the presynaptic neuron into the synaptic cleft. It then binds to ACh receptors on the postsynaptic neuron, causing ion channels to open and allowing for the transmission of the nerve impulse. Any remaining ACh is broken down by the enzyme acetylcholinesterase, ensuring that the signal is quickly terminated.
What destroys ACh?
Acetylcholinesterase (AChE) is an enzyme that breaks down acetylcholine (ACh) into choline and acetate, thus destroying ACh. This process helps in regulating the levels of ACh at the synaptic cleft and terminating its action.
What is the name of the cell that releases the neurotransmitters?
Exocytosis. As a result of the influx of Calcium ions, the synaptic vesicles transport the neurotransmitter Ach (Acetylcholine) to the presynaptic membrane, the vesicles fuse to the membrane, and the neurotransmiffer, Ach, diffuses. Once the neurotransmitters cross the synaptic cleft, they bind to the receptors on the post synaptic membrane. Hope it helps a bit.
Why doesn't acetylcholine remain on the post-synaptic process?
Acetylcholine (ACh) does not remain on the post-synaptic membrane because it is rapidly broken down by the enzyme acetylcholinesterase. This enzymatic degradation occurs in the synaptic cleft, preventing prolonged stimulation of the post-synaptic receptors. Additionally, the reuptake of choline into the pre-synaptic neuron helps recycle components for future neurotransmitter synthesis. This process ensures that synaptic transmission is brief and precisely regulated.
What is the chemical transmitter released at the neuromuscular junction?
Acetylcholine is the primary chemical transmitter released at the neuromuscular junction. It binds to acetylcholine receptors on the muscle cell membrane, leading to muscle contraction.
How is acetylcholine (ACh) removed from the synaptic cleft?
Acetylcholine (ACh) is removed from the synaptic cleft through a process called enzymatic degradation. The enzyme acetylcholinesterase breaks down ACh into its components, acetate and choline, which are then taken back up into the presynaptic neuron for recycling or further processing.
Which structure contains vesicles with acetylcholine?
Synaptic vesicles in the axon terminals of neurons contain acetylcholine. Acetylcholine is a neurotransmitter that is released from these vesicles into the synaptic cleft to transmit signals to target cells or other neurons.

Synaptic vesicles in the axon terminal of a motor neuron contain what neurotransmitter?
Synaptic vesicles store neurotransmitters to be released into the synapses. In the case of most motoneurons, this neurotransmitter is acetylcholine (ACh). The neurons that interface with the sympathetic nervous system, also technically motoneurons, release norepinephrine.
What are the names of some common neurotransmitters?
Acetylcholine or aka ACH is the neurotransmitter that is released from the axon terminal to through the neuromuscular junction across the synaptic cleft which binds to the ACH receptors on the end motor plate of the Sarcolema.
After nervous stimulation stops ACh in the synaptic cleft is prevented from continuing stimulation of contraction by what?
acetylcholinesterase destroying the ACh
After nervous stimulation stops what prevents ACh in the synaptic cleft from continuing to stimulate contraction?
Acetylcholinesterase destroying the ACH

Why physostigmine is the antidote for atropine?
Physostigmine inhibit AchE (the enzyme that hadrolyse Ach), so Ach accumulate at synaptic cleft and banish the effect of atropine
