nicotinic and muscarinic
nicotinic acetylcholine receptors (nAChR, also known as "ionotropic" acetylcholine receptors) are particularly responsive to nicotinemuscarinic acetylcholine receptors (mAChR, also known as "metabotropic" acetylcholine receptors) are particularly responsive to muscarine.Nicotinic and muscarinic are two main kinds of "cholinergic" receptors.
The two types of receptors that bind acetylcholine are nicotinic receptors and muscarinic receptors. Nicotinic receptors are ionotropic receptors found at the neuromuscular junction and in the autonomic ganglia, while muscarinic receptors are G-protein coupled receptors found in various organs like the heart, lungs, and digestive system.
There are two main types of receptors for acetylcholine: muscarinic receptors, which are G-protein coupled receptors, and nicotinic receptors, which are ligand-gated ion channels. Each type of receptor is further classified into different subtypes based on their structure and function.
ACH receptors can be defined as an integral membrane protein that responds to the binding of acetylcholine, a neuoyansmitter. Two example are nicotinic acetyl line receptors and muscarinic acetylcholine receptors. .
Acetylcholine receptors function as neurotransmitter receptors that respond to the neurotransmitter acetylcholine (ACh). They are primarily found in the neuromuscular junction and in the central and peripheral nervous systems. These receptors can be categorized into two main types: nicotinic receptors, which are ionotropic and mediate fast synaptic transmission, and muscarinic receptors, which are metabotropic and are involved in slower, modulatory signaling pathways. Their activation plays a crucial role in muscle contraction, autonomic functions, and cognitive processes.
The neurotransmitter is called acetylcholine. Cholinergic receptors are of two kinds: nicotinic receptors, which are situated in striated muscles and muscarinic receptors, which are situated in parasympathetically innervated structures.
it is an alpha-toxin that binds to acetylcholine binding sites on the postsynaptic cell membrane, which prevents the acetylcholine from acting. Curare blocks synaptic transmission by preventing neural impulses to flow from neuron to neuron. It does allow the action potential to travel in the axon, it just doesn't pass it on to the dendrite.
There are two receptors that neurotransmitters interact with: ligand-gated receptors or ionotropic receptors and G protein-coupled receptors or metabotropic receptors depending on the neurotransmitter (the ligand). When the ligand binds with the neurotransmitter receptor it causes a sequence of chemical reactions to relay signals.Brought to you by altogenlabs.com
Two types of receptors involved in the cough reflex include irritant receptors, which are sensitive to noxious stimuli in the airways, and stretch receptors, which respond to mechanical distortion of the airways. Activation of these receptors triggers the cough reflex to protect the respiratory tract.

The two types of temperature senses are warm receptors and cold receptors. Warm receptors detect increases in temperature, while cold receptors detect decreases in temperature. Together, they help our bodies maintain a stable internal temperature.
There are not tow types of sensory receptors in the skin there are many types of sensory receptors in the skin i.e., in the CUTANEOUS RECEPTORS of the MECHANORECEPTORS. They are the: Meissner's corpuscles, Merkel's disc, Paccinian corpuscles, Ruffini's end organs, Free Nerve Endings and Hari Follicel Organs.
