Neurotransmitters find their way to and subsequently trigger firing of that neuron?
Excitatory neurotransmitter
When ADH binds to receptor sites on distal tubule cells?
read textbooks
Do Dendrites release neurotransmitters into the extracellular space during nerve impulse transmissions?
Receive, fundamentally, but then subsequently release when its job is done. The axon releases neurotransmitters into the synaptic cleft, where they diffuse across and fit into the receptor sites on ligand-gated ion pores located on the dendrites, where they act to open the ion pores so as to initiate the propagation of the neural signal along the dendrite ; however, those same receptor sites subsequently do release the neurotransmitters, so they can be re-absorbed and re-used by the axon terminals to pass neural signals to the dendrite as subsequent action potentials reach the ends of the axons.
Many hormones are thought to function by acting on receptor sites in the?
cytoplasm
Are hormones transported throughout the whole body?
Yes. Hormones are transported throughout the body, via the bloodstream. They do not, however, effect every cell. Only certain cells in the body have the proper receptor sites to accomodate hormones. Therefore, even though hormones are transported right through the body, they only create a reaction for certain things.
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
Do t cells have receptor sites?
Yes.
Neurotransmitters find their way to and subsequently trigger firing of that neuron?
Excitatory neurotransmitter
What part of the neuron was called the post-synoptic part of the neuron in humans?
postsynapse: containing receptor sites for the neurotransmitters on the dendrites.
What is an adrenergic receptor?
An adrenergic receptor is any of several sites in the surface membranes of cells innervated by adrenergic neurons.
When ADH binds to receptor sites on distal tubule cells?
read textbooks
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.
Why will certain viruses attach to only one type of cells?
4. receptor sites
How do neurotransmitters initiate action potentials?
Neurotransmitters can help bring another neuron to the point where it initiates an action potential by binding to postsynaptic receptor sites. If the receptors are the type that allow positively charged ions to flux through the cell membrane, and if this happens on a large enough scale (i.e., multiple sites are hit at once), then the probability of an action potential occurring becomes very high.
Why are neurotransmitters sometimes referred to as a key?
When an action potential reaches the knoblike terminals at an axon's end, it triggers the release of chemical messengers called neurotransmitters. Within 1/10,000th of a second, the neurotransmitter molecules cross the synaptic gap and bind to receptor sites on the receiving neuron-as precisely as a key fits a lock.
