What passes from the neuron to the muscle cells and what effect does it produce?
Neurotransmitters pass from the neuron to the muscle cells, leading to muscle contraction. This process is known as synaptic transmission, where the release of neurotransmitters triggers a response in the muscle cells by activating receptors on the muscle cell membrane, leading to muscle contraction.
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 happens to ACh once it has bound to its receptor?
Once acetylcholine (ACh) binds to its receptor, it can either stimulate or inhibit the activity of the cell. This activation triggers a cellular response, such as muscle contraction or nerve cell communication. After its action, ACh is rapidly broken down by the enzyme acetylcholinesterase to terminate the signal.
After ACh attaches to its receptors at the neuromuscular junction the next step is?
If enough ACh is released, the sarcolemma at that point becomes temorarily more permeable to sodium ions, which rush into the muscle cell and to potassium ions which diffuse out of the cell. Although more sodium ions enter than posassium ions leave.
What change does ACh cause in an ACh receptor?
Acetylcholine (ACh) binding to an acetylcholine receptor triggers a conformational change in the receptor protein, leading to the opening of an ion channel within the receptor. This allows specific ions, such as sodium or potassium, to flow across the cell membrane, resulting in changes in membrane potential and ultimately leading to cellular responses.

What chemical into the muscle cell membrane causes a temporary rush?
Acetylcholine (ACh)
What neurotransmitter control the somatic nervous system and how does it work?
Acetylcholine (ACh) is the only neurotransmitter used in the motor division of the somatic nervous system. It works by binding to acetylcholine receptors on skeletal muscle fibers and opening ligand-gated sodium channels in the cell membrane.

What part of the muscle cell membrane contain acetylcholine receptors?
Acetylcholine receptors are located on the motor end plate of the muscle cell membrane. This specialized region is where the nerve cell communicates with the muscle cell, allowing for the initiation of muscle contraction in response to acetylcholine binding to its receptors.
Acetylcholine a quaternary ammonium compound can not penetrate membranes why?
Ach has a positive charge on the Nitrogen. This makes it harder for Ach to pass through lipophillic membranes which are nonpolar. Remember likes attract likes. Ach would prefer a polar environment like water.
What has the author Friedrich Ach written?
Friedrich Ach has written: 'Hoch ach tungsvoll'

This allows specific ions, such as sodium or potassium, to flow across the cell membrane, resulting in changes in membrane potential and ultimately leading to cellular responses.
What could ACh causes in the dendrites of the postsynaptic neuron?
It would initiate an "action potential," or in other words an electrical impulse carried from nerve to nerve. Neurotransmitters such as ACh (Acetylcholine) are like a medium of exchange between nerve cells, at the end of the neural fiber ACh is released, then picked up (smelled?) by the receptors at the end of another fiber, which can trigger such an impulse. And so these "action potentials" are passed rapidly from cell to cell.
