How is the neurotransmitter acetylcholine inactivated at the parasympathetic terminal receptor site?
Acetylcholine is primarily inactivated at the parasympathetic terminal receptor site by the enzyme acetylcholinesterase. Acetylcholinesterase breaks down acetylcholine into choline and acetate, which are then taken back up by the presynaptic terminal for further use in neurotransmitter synthesis. This inactivation process allows for the rapid termination of acetylcholine signaling and helps maintain proper neurotransmitter balance in the synapse.
What is the difference between a stimulus impulse receptor and effector?
A Receptor is referring to a sense organ, like a nerve ending. An Effector is referring to a muscle capable of reflecting to a stimulus. By definition, receptor and effector are antonyms.
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.
Where would you not find cholinergeric nicotinic receptor?
all parasympathetic target organs
Is a control mechanism that intensifies an earlier reaction A sensory receptor An effector Negative feedback Positive feedback?
sensory receptor
What will happen if Acetylcholine receptors are destroyed?
If the acetylcholine receptor was destroyed that the effector cells cannot respond or detect the neurotransmitter, resulting in muscle paralysis.

What are anticholinergics?
Anticholinergics are a class of medications that inhibit parasympathetic nerve impulses by selectively blocking the binding of the neurotransmitter acetylcholine to its receptor in nerve cells.
What is the receptor effector and stimulus?
Stimulus is like the cause of something or the theme. The receptor is what you use fir the stimulus e.g you look at a tv guide ( stimulus) and the receptor is your eyes because you use them to see it. The effector is the muscle used To use the tv guide so this could be your hand

How does atropine work?
Anticholinergic agent/ parasympatholytic that inhibits the action of acetylcholine at the postganglionic parasympathetic receptor sites. Increases the heart rate in life threatening bradyarrhythmias.

A molecule that is released from synaptic vesicles and serves as the means of communication from one neuron to the next or from one neuron to an effector cell?
a neurotransmitter such as acetylcholine, or dopamine. Even a neuropeptide.They will cause a receptor gated channel to open post synaptically
What is effector?
An effector is a molecule or protein that can bind to a specific site on an enzyme, receptor, or other protein to regulate its activity. Effectors can activate or inhibit the function of the protein they bind to, ultimately influencing cellular processes.
In myasthenis gravis what cellular receptors are affected?
Acetylcholine receptors at neuromuscular junctions are affected in MG. MG is an autoimmune disorder in which the body produces antibodies against its own protein, the acetylcholine receptor. These antibodies block the receptor, preventing the binding of acetylcholine and inhibiting the function of the receptor, which is to initiate a depolarization in muscle cells that will lead to contraction. Fewer available acetylcholine receptors means greater stimuli, i.e. more acetylcholine has to be released to cause a contraction. This manifests physically as serious weakness resulting from inability to move muscles at will. The name of the disease describes the symptoms quite well (my-, muscle; -a-, without; -sthenia, strength; gravis, heavy, serious).
What is the receptor in pupillary reflex and the effector do both change simultaneously in pupillary reflex?
The receptor in the pupillary reflex is the optic nerve, which senses changes in light intensity. The effector is the circular and radial muscles of the iris, which control the size of the pupil. In the pupillary reflex, both the receptor and the effector work together to adjust the size of the pupil to regulate the amount of light entering the eye.
Which structure of a feedback system receives output from the control center?
The structure that receives output from the control center in a feedback system is typically the effector. The effector is responsible for carrying out the response dictated by the control center to maintain homeostasis or achieve the desired outcome.
