The neurotransmitter that causes an individual to feel more alert is norepinephrine. It plays a key role in the body's fight-or-flight response, increasing heart rate, blood flow to muscles, and overall alertness.
The combining of the neurotransmitter with the muscle membrane receptors causes the membrane to become permeable to sodium ions and depolarization of the membrane. This depolarization triggers an action potential that leads to muscle contraction.
A neurotransmitter is a chemical messenger that carries signals between neurons in the brain and nervous system. It plays a crucial role in regulating various physiological processes, including mood, cognition, and behavior.
When a neurotransmitter binds to its receptor on the motor endplate, it triggers the opening of ion channels in the postsynaptic membrane. This allows for the influx of ions, typically leading to depolarization of the muscle cell membrane and initiation of a muscle action potential. Subsequently, this leads to contraction of the muscle fiber.
What is neurotransmitter that when excess or in minimal secretion produces behavior maladjustment?
Glutamate is the neurotransmitter that is seen in excess after a stroke. This excess can lead to excitotoxicity, causing damage to brain cells and worsening the outcome of the stroke.

As far as we know, dopamine is the main culprit in psychosis. Autospies have shown excess dopaminergic receptors in the brain's of people who suffered psychosis. Other neurotransmitters are also affected.
Excitatory neurotransmitter
Different antipsychotics do different things, but all of them help to treat the mental disorder called psychosis, which is a loss of touch with reality. Psychosis can include symptoms like hearing voices or seeing things that are not there, having strange or illogical thoughts, or having little or no control over their emotions and thoughts.Antipsychotics affect the neurotransmitters that help the brain communicate. It is believed that psychosis is caused by abnormal communication within the brain, so these drugs will block those and enhance the normal communication. The specific neurotransmitter involved is dopamine, which has been shown to be produced in excess during psychotic episodes. Antipsychotics act to block the excess dopamine and allow more normal brain function.
The neurotransmitter epinephrine can cause the blood pressure to become low. This neurotransmitter also regulated the heart rate. It is often controlled by stress.
Reabsorption of excess neurotransmitter molecules refers to the process where neurotransmitters are taken back up from the synaptic cleft into the presynaptic neuron by transporters known as reuptake pumps. This process helps regulate neurotransmitter levels, preventing overstimulation of the postsynaptic neuron. Dysfunction in this reabsorption process can lead to neurological disorders such as depression and anxiety.
inhibitory transmitters
Beta 1 receptors
These are medications prescribed to decrease the frequency, duration, and extremity of psychotic episodes that some people experience. Psychotic episodes stem from dysfunction in the brain cells or messaging system.
