What are the chemicals that are released at an axon terminal and can either excite or inhibit other neurons called?
These are called neurotransmitters.
What is the most important function of endorphins?
Enable neurons to excite or inhibit each other
What does the process of transmitting a nerve impulse from one neuron to another involve?
When a neurotransmitter lands on their receptor site, they can either excite of inhibit the receiving cell. To excite a cell, positive sodium ions flow to it, which depolarizes the membrane in a similar way to a nerve impulse. The depolarizing effect spreads through the membrane and only last for 1/3 of a millisecond.
What can excite a neuron or stop it from transmitting?
neurotansmitter
Which 'neurotransmitters' excite energy and inhibit lethargy?
I am not an expert in this field, but we did study psychiatric disorders recently in my nursing classes. The neurotransmitter serotonin controls mood and sleep (among other things), and when you decrease its levels (or if uptake is blocked), people end up with clinical depression. Antidepressants work to increase serotonin (or increase its uptake). Also, GABA (gamma-Aminobutyric acid) is an inhibitory neurotransmitter that regulates excitability in the nervous system. So if there is too little GABA present, the hormones that cause excitability run wild and you end up with anxiety (overstimulation). Anxiolytics (anti-anxiety meds) work to increase GABA, which inhibits that excitabililty and slows those anxious feelings.

What makes the cell body fire?
The cell body fires when it receives enough input signals, usually in the form of neurotransmitters from other neurons. These signals can excite or inhibit the cell body, changing its membrane potential until it reaches a threshold that triggers an action potential.
What type of excitatory neurotransmitter is secreted by motor neurons innervating skeletal muscle?
Acetylcholine is the excitatory neurotransmitter released by neurons innervating skeletal muscles. Acetylcholine release stimulates muscle contraction by acting at the nicotinic-acetylcholine receptor on the surface of the muscle cell.
What does psychostimulant mean?
Psycho = brain stimulate = to excite so it would mean to stimulate or excite the brain. Good examples would be methamphetamine, amphetamine, cocaine and the like. I suppose you could also qualify anti-depressants as psychostimulants because they enhance neurotransmitters, thus increasing brain activity.
What is excite in tagalog?
"Excite" in Tagalog can be translated as "magpasigla" or "magpa-excite."
