Astrocytes and microglia are two types of glial cells that help remove neurotransmitters from receptor sites in the brain. They play a crucial role in maintaining the balance of neurotransmitters in the synapse by clearing excess neurotransmitters and preventing overstimulation of the neurons.

Neurotransmitters find their way to and subsequently trigger firing of that neuron?
Excitatory neurotransmitter
What are receptor proteins made up of?
Receptor proteins are typically composed of amino acids arranged in specific sequences to form a three-dimensional structure. These proteins have binding sites that allow them to interact with specific ligands, such as hormones or neurotransmitters, to initiate a cellular response. The specific structure of a receptor protein determines its ability to recognize and bind to particular ligands.
Do Dendrites release neurotransmitters into the extracellular space during nerve impulse transmissions?
No, dendrites do not release neurotransmitters during nerve impulse transmissions. Dendrites receive signals from other neurons via neurotransmitters but do not release neurotransmitters themselves. It is the axon terminals that release neurotransmitters into the synaptic cleft at the synapse to communicate with the next neuron.
When ADH binds to receptor sites on distal tubule cells?
When ADH binds to receptor sites on distal tubule cells in the kidneys, it increases the water permeability of the tubules, allowing them to reabsorb more water from the urine. As a result, less water is excreted, leading to concentrated urine production and helping to regulate the body's water balance.
Neurotransmitters are released in a synapse and bind to?
a receptor structure in a ligand-gated sodium-ion pore. The receptor is like a cave which is an outer part of a protein structure which also has a tunnel which can be open or closed, and the presence of the neurotransmitter causes the tunnel (pore) to open.
What are holes in the surface of the dendrites or certain cells of the muscles and glands that are shaped to fit only certain neurotransmitters?
Neurotransmitter receptor sites on ligand-gated ion pores.
What holes are in the surface of the dendrites or certain cells of the muscles and glands that are shaped only to fit certain neurotransmitters?
receptor sites
Neurotransmitters find their way to and subsequently trigger firing of that neuron?
Excitatory neurotransmitter
What is an adrenergic receptor?
An adrenergic receptor is any of several sites in the surface membranes of cells innervated by adrenergic neurons.
Do neurotransmitters pass directly from the axon to the dendrite?
No, neurotransmitters are released from the axon terminal into the synaptic cleft between the axon terminal and the dendrite. They then bind to receptor sites on the dendrite to transmit signals from one neuron to another.
What mimic or enhance the effects of a neurotransmitter on the receptor sites of the next cell increasing or decreasing the activity of that cell?
Agonists mimic or enhance the effects of neurotransmitters by binding to the receptor sites of the next cell and increasing the activity of that cell. Antagonists, on the other hand, block or inhibit the effects of neurotransmitters, resulting in decreased activity of the cell.
Do t cells have receptor sites?
Yes, T cells have receptor sites called T cell receptors (TCRs) on their cell surface. These TCRs recognize specific antigens presented by antigen-presenting cells, activating the T cell to mount an immune response.
What are receptor proteins made up of?
Receptor proteins are typically composed of amino acids arranged in specific sequences to form a three-dimensional structure. These proteins have binding sites that allow them to interact with specific ligands, such as hormones or neurotransmitters, to initiate a cellular response. The specific structure of a receptor protein determines its ability to recognize and bind to particular ligands.
What forms receptor sites on the post synaptic cell membrane?
Protein molecules on the post-synaptic cell membrane form receptor sites that bind with neurotransmitters released from the pre-synaptic neuron. This binding triggers downstream signaling pathways within the post-synaptic cell, leading to various cellular responses.
What is an adrenoreceptor?
An adrenoreceptor is an adrenergic receptor, any of several sites in the surface membranes of cells innervated by adrenergic neurons.
How hallucinogens cause hallucinations?
The exact nature of how hallucinogens cause hallucinations is not known, but it is thought that they mimic the actions of neurotransmitters and bind to receptor sites in the brain. This causes a person to experience sensations that are not real.
Do Dendrites release neurotransmitters into the extracellular space during nerve impulse transmissions?
No, dendrites do not release neurotransmitters during nerve impulse transmissions. Dendrites receive signals from other neurons via neurotransmitters but do not release neurotransmitters themselves. It is the axon terminals that release neurotransmitters into the synaptic cleft at the synapse to communicate with the next neuron.
