The sympathetic nervous system releases the neurotransmitter?
Norepinephrine (otherwise known as Noradrenaline). Acetylcholine IS NOT the right answer.
Is adrenaline and noradrenaline the same?
No, adrenaline and noradrenaline are not the same. They are both hormones produced by the adrenal glands in response to stress, but they have slightly different effects in the body. Adrenaline is responsible for the "fight or flight" response, while noradrenaline plays a role in regulating blood pressure and heart rate.
Is noradrenaline excitatory?
Yes, noradrenaline is generally considered excitatory in the brain and central nervous system. It promotes arousal, alertness, and the "fight or flight" response by enhancing neuronal activity and transmission.
How does noradrenaline bind to the beta receptors?
Noradrenaline has an amine group with a positive charge as well as two OH groups attached to its benzene ring. The amine group can form an ionic bond with the COOH group with aspartic acid residues in the receptor. Meanwhile, the OH groups can form hydrogen bonds with the OH groups of the serine residues in the receptor. These bonds will lead to noradrenaline binding with the beta receptor.
What is medullary hormones?
Medullary hormones are hormones secreted by the adrenal medulla, including epinephrine (adrenaline) and norepinephrine (noradrenaline). These hormones are released in response to stress and help regulate the "fight or flight" response in the body.
What are some important neurotransmitters?
Acetylcholine, adrenaline, noradrenaline, serine GABA. dopamine etc.
How can adrenergic drugs stimulate the adrenergic nerves?
This is done through several mechanisms: - Stimulating noradrenaline to be released - Mimicking noradrenaline's action on the receptors -Preventing noradrenaline to be broken down and reuptaken

How does noradrenaline affect the heart rate?
It doesnt
What is SNRI?
SNRI is a class of antidepressants known better as Serotonin and Noradrenaline Reuptake Inhibitors. They increases (to some degree) the amount of serotonin and noradrenaline (norepinephrine) in the brain.
What does noradrenaline do?
It can cause vascular smooth muscle contraction
What is the Short term stress hormone?
adrenaline and noradrenaline
What has the author Charlotte Sachs written?

What has the author Ulf S von Euler written?
Ulf S. von Euler has written: 'Prostaglandins' -- subject(s): Prostaglandins, Prostaglandine 'Noradrenaline' -- subject(s): Noradrenaline
How is noradrenaline and acetylcholine involved in the regulation of the heart?
Noradrenaline is released when the medulla oblongata sends impulses along the nervous system and when the chemical reaches the S.A node (pacemaker), the noradrenaline makes the node fire more rapidly. Acetylcholine reaches the S.A node, and slows down the firing of the S.A node.
Is noradrenaline excitatory?
Yes, noradrenaline is generally considered excitatory in the brain and central nervous system. It promotes arousal, alertness, and the "fight or flight" response by enhancing neuronal activity and transmission.
