what is the function of ach receptors? The acetylcholine receptor is an essential link between the brain and the muscles, so it is a sensitive location for attack. Many organisms make poisons that block the acetylcholine receptor, causing paralysis.
What receptors are activated by ACh? The acetylcholine receptor (AChR) is a membrane protein that binds to the neurotransmitter acetylcholine (Ach). These receptors can be divided into two main types of distinct receptors, nicotinic and muscarinic.
Where are the receptors for ACh? As indicated in Table I, nicotinic receptors are located at the NMJ, autonomic ganglia and sparsely in the CNS. The NMJ nicotinic ACh receptor consists of five polypeptide subunits: two α subunits and one each of β, δ, and γ (see Figure 11.8). A funnel-shaped internal ion channel is surrounded by the five subunits.
Do neurons have receptors for all neurotransmitters? Neurotransmitter receptors are present on both postsynaptic neurons and presynaptic neurons with the former being used to receive neurotransmitters and the latter for the purpose of preventing further release of a given neurotransmitter.

Do baby bunnies have good eyesight?
The answer is yes and no. Rabbits tend to be farsighted, which means they can see long distances really well. However, their vision for items nearby isn’t always so great. Part of the reason for this is the placement of the eyes on a rabbit’s head.

Why can steroid hormones cross the membrane and bind to intracellular receptors?
Because a lipid-derived hormone such as a steroid hormone can diffuse across the membrane of the target cell, they bind to intracellular receptors residing in the cytoplasm or in the nucleus. The cell signaling pathways induced by steroid hormones regulate specific genes by acting as transcription regulators.
How a steroid hormone interacts with an intracellular receptor?
Steroid hormones regulate cellular processes by binding to intracellular receptors that, in turn, interact with discrete nucleotide sequences to alter gene expression. Because most steroid receptors in target cells are located in the cytoplasm, they need to get into the nucleus to alter gene expression.
