Chemicals that cross the synaptic gap and bind to receptors on another neuron are called?
nuerotransmitter
What are the types of alpha receptors?
There are two main types of alpha receptors: alpha-1 and alpha-2. Alpha-1 receptors are located in smooth muscle cells of blood vessels, causing vasoconstriction when activated. Alpha-2 receptors are located both presynaptically and postsynaptically in the central and peripheral nervous systems, regulating the release of neurotransmitters.
What are internal receptors?
Internal receptors are proteins located inside a cell that can bind to specific signaling molecules, such as hormones or neurotransmitters, and initiate a cellular response. They transmit the signal from the outside of the cell to the inside, leading to changes in gene expression, metabolism, or cell function. Examples include nuclear receptors and enzyme-linked receptors.
Do receptors catalyze reactions?
No, receptors do not catalyze reactions. Receptors on cell membranes or within cells bind to specific ligands, such as hormones or neurotransmitters, to initiate cellular responses but they do not themselves catalyze chemical reactions.
What is in the dendrites of the postsynaptic nerve?
Dendrites of a postsynaptic nerve contain receptors for neurotransmitters released by the presynaptic neuron. These receptors detect and respond to the neurotransmitters by initiating an electrical signal that travels towards the cell body. This signal determines whether the neuron will fire an action potential.
Neurotransmitters attach to what molecules in the cell membrane?
Neurotransmitters attach to specific proteins called receptors on the cell membrane. These receptors are typically ligand-gated ion channels or G protein-coupled receptors that initiate cellular responses when neurotransmitters bind to them.
What does an axon release when an impulse reaches the end of it?
Neurotransmitters to the synapse and the neurotransmitters bind with the receptors releasing the second messengers.
Why can't all receptors be located inside the cell?
Not all receptors can be located inside the cell because some receptors need to be on the cell surface to interact with molecules outside the cell, such as hormones or neurotransmitters. These external molecules cannot pass through the cell membrane to reach receptors inside the cell.
What neurotransmitters bind to?
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

How do drugs affect the process of synaptic transmission?
They can act in a number of ways, both presynaptically and postsynaptically. They can affect how vescicles release neurotransmitters, how neurotransmitters are cleaved/reuptake, they can block receptors, destroy receptors, agonistically bind to receptors which mimics the neurotransmitter. These are a few.
