Do all neurotransmitters act the same way?
No, not all neurotransmitters act the same way. They have different functions, mechanisms of action, and effects on target cells. Some neurotransmitters, like glutamate, primarily act as excitatory signals, while others, like gamma-aminobutyric acid (GABA), serve as inhibitory signals. Additionally, they may interact with various receptors, leading to diverse physiological responses in the nervous system.
Neuron receives a series of stimuli whose effect is excitatory but subthreshold?
Then it does nothing unless the stimuli arrive at the same time to be above the threshold. Or the stimuli may undergo temporal summation (with buildup of neurotransmitters in the synapse), where their effects add up over time to be above the threshold.
The tutor asks the students what determines whether a neurotransmitter will have an inhibitory or excitatory effect on the synaptic process. One student answers that it depends on the nature of the ne?
The effect of a neurotransmitter is determined by the type of receptors it binds to on the postsynaptic neuron. If the neurotransmitter activates ion channels that allow positive ions to flow into the neuron, it typically has an excitatory effect, leading to depolarization. Conversely, if it opens channels for negative ions or closes channels for positive ions, it results in hyperpolarization and an inhibitory effect. Thus, the same neurotransmitter can have different effects depending on the receptor type and the ions involved.
Do all microbes go to the same organs?
Hehhehehehe love life
What is a channel linked receptor?
A channel linked receptor transduces functions of the same protein molecule. An example of a channel linked receptor are neurotransmitters in the brain.

What is the difference between the way excitatory and inhibitory transmitters work?
As a rule more than one presynaptic action potential is needed to fire the postsynaptic neuron or muscle so that the trigger to initiate an action potential are either many subthreshold local potentials from different sources or from the same neuron received within a short period of time. The first case is called spatial summation and the second case is called temporal summation. Whether a postsynaptic potential (another term for a local potential) is excitatory or inhibitory depends on what ion channels are affected by the transmitter released from the presynaptic vesicles.
What organs does a tiger have?

What are the internal organs of the grizzly bear?

How does the anatomical arrangement of the organs in the cat compare to that of?
Cats have the same respiratory organs as humans and the same arrangement of organs as some other mammals. Online diagrams can be found on a lot of websites to use as comparison to other animals organs.
What do the chemicals agonists mimic the activity of?
Depending on the type of agonist, it can mimic the activity of hormones or medications.
Why are twin organs the same?
because they use and eat the same things

yes
Do all animals have the same kinds of organs?
no
