The endocrine system releases adrenaline when the nervous system experiences stress
shot
Acetylcholine.
You do not have single neurotransmitter, which is released from axon terminals. There are many. Some facilitate the conduction of the impulse and others inhibit the same. You have acetylcholine, norepinephrine, dopamine and many others acting as neurotransmitter.
acetylecholine
acetylcholine
Adrenocorticotropic hormone (ACTH)
The neurotransmitter that helps the body return to normal after a stress response is the noradrenaline. It is also used to raise blood pressure.
Apenisylcholine
These are typically known as neuromodulators; they can either change the rate at which a neurotransmitter is released, or alter the response to a certain neurotransmitters.
Endorphins
neuromodulator
a hormone known as KAP is released by hypothalamus when insane
blood pressure increases hormones are released
blood pressure increases hormones are released
The neurotransmitter epinephrine can cause the blood pressure to become low. This neurotransmitter also regulated the heart rate. It is often controlled by stress.
The substance that is released at an axonal ending to propagate the nerve impulse to the next nerve or muscle is called
Norepinephrine and epinephrine (adrenaline).
Calcium (Ca2+) channels open on the synaptic end bulb in response to depolarization (from the action potential), inducing exocytosis of synaptosomes containing neurotransmitter, resulting in neurotransmitter being released into the synaptic cleft...further propagating the signal to the next neuron or set of neurons.
