What else can I help you with?
When the parasympathetic division is stimulated what neurotransmitter is released at the effector organ?
Acetylcholine is the main neurotransmitter released at the effector organ when the parasympathetic division is stimulated.
What stimulates norepinphrine?
Norepinephrine as a hormone is stimulated by epinephrine and angiotensin II. Norepinephrine as a neurotransmitter is stimulated by electrical impulses from the sympathetic nervous system.
What is the difference between presynaptic and postsynaptic neurons?
Presynaptic neurons release the neurotransmitter in response to an action potential. Postsynaptic neurons receive the neurotransmitter (and can however become presynaptic to the next nerve cell, if the neurotransmitter has stimulated the cell enough).
What neurotransmitter is in the locus coeruleus?
The locus coeruleus predominantly releases the neurotransmitter norepinephrine (noradrenaline). This neurotransmitter plays a key role in the regulation of arousal, attention, and the stress response.
What neurotransmitter causes low blood pressure?
The neurotransmitter epinephrine can cause the blood pressure to become low. This neurotransmitter also regulated the heart rate. It is often controlled by stress.
Which neurotransmitter helps your body return to normal after the stress response?
The neurotransmitter that helps the body return to normal after the stress response is called serotonin. It plays a role in regulating mood, sleep, and appetite, which are often affected by stress. Serotonin helps to counterbalance the effects of stress hormones like cortisol, promoting relaxation and a sense of well-being.
What is the release of ACTH stimulated by?
Release of ACTH is stimulated by corticotropin releasing hormone (CRH) from the hypothalamus in response to stress or low levels of cortisol in the body.
Neurotransmitter released in response to stress?
The primary neurotransmitter released in response to stress is norepinephrine. It activates the body's "fight or flight" response, increasing heart rate, blood pressure, and alertness to help cope with the stressful situation.
Which neurotransmitter is involved in sweating?
Acetylcholine is the primary neurotransmitter involved in stimulating the sweat glands to produce sweat. Its release activates sweat production in response to heat, exercise, stress, or emotional stimuli.
The secretion of sweat is stimulated by what?
That is a good question! Sweat glands get the nerve supply from the sympathetic trunk. So anatomically they get sympathetic nerve supply. But the neurotransmitter at the target cells is acetylcholine. So functionally or physiologically, the sweat glands get the parasympathetic nerve supply.
Epinephrines are known as when functioning as a hormone instead of a neurotransmitter?
Epinephrine is known as adrenaline when functioning as a hormone instead of a neurotransmitter. Adrenaline is released by the adrenal glands in response to stress and prepares the body for the "fight or flight" response.
What usually stimulates release of hormones from the adrenal medulla?
The release of hormones from the adrenal medulla is stimulated by the sympathetic nervous system in response to stress or perceived danger. This triggers the release of adrenaline and noradrenaline, which help the body respond to the "fight or flight" response.
