Yes, the Adrenal glands secrete epinephrine (adrenaline) into the blood stream when the brain detects a threat. This gives the muscles an added boost to their strength. The brain determines if it will run away or fight whatever the threat is, thus the saying, 'fight or flight'.
No, hormones from the adrenal medulla are released in response to sympathetic stimulation, not vagal stimulation. The adrenal medulla is innervated by sympathetic preganglionic neurons which release acetylcholine, activating the release of epinephrine and norepinephrine from the adrenal medulla.

What gland produces epinephrine and norepinephrine?
The adrenal gland (more specifically the Adrenal Medulla).
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.
What gland is a modified sympathetic ganglion that produces amine hormones?
The adrenal medulla is a modified sympathetic ganglion that produces amine hormones, such as adrenaline and noradrenaline. These hormones are released in response to stress and help prepare the body for fight-or-flight responses.
What is the inner region of the adrenal gland?
The inner region of the adrenal gland is called the adrenal medulla. It secretes hormones such as adrenaline (epinephrine) and noradrenaline (norepinephrine) in response to stress or stimulation of the sympathetic nervous system. These hormones help the body respond to "fight or flight" situations by increasing heart rate, blood flow, and energy availability.
What is adrenal cortex?
The adrenal cortex is the outer layer of the adrenal glands located on top of the kidneys. It secretes hormones such as cortisol, aldosterone, and small amounts of sex hormones. These hormones play a crucial role in regulating metabolism, blood pressure, electrolyte balance, and the body's response to stress.
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 hormones are released in response to excessive blood loss?
Epinephrine by adrenal glands to stimulate vasoconstriction
What gland produces epinephrine and norepinephrine?
The adrenal gland (more specifically the Adrenal Medulla).
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.
What gland is a modified sympathetic ganglion that produces amine hormones?
The adrenal medulla is a modified sympathetic ganglion that produces amine hormones, such as adrenaline and noradrenaline. These hormones are released in response to stress and help prepare the body for fight-or-flight responses.
What is the function of adrenal medulla?
The adrenal medulla secretes hormones called adrenaline and noradrenaline in response to stress or danger. These hormones help to increase heart rate, blood pressure, and energy levels, preparing the body for a "fight or flight" response.
What releases hormones from the adrenal cortex?
The adrenal cortex releases hormones such as cortisol, aldosterone, and sex hormones like testosterone and estrogen. These hormones play key roles in regulating metabolism, blood pressure, and stress response in the body.
Which hormones are released by the adrenal glands?
epinephrine and norepinephrine are released by the adrenal glands
What is the inner region of the adrenal gland?
The inner region of the adrenal gland is called the adrenal medulla. It secretes hormones such as adrenaline (epinephrine) and noradrenaline (norepinephrine) in response to stress or stimulation of the sympathetic nervous system. These hormones help the body respond to "fight or flight" situations by increasing heart rate, blood flow, and energy availability.
What are the hormones in the adrenal medulla?
Adrenal medulla is a portion of the adrenal gland. The adrenal medulla is located within the inner portion of the gland and is associated with stress.
What cells produce glucocorticoids?
Glucocorticoids are produced by the adrenal cortex, specifically by the zona fasciculata layer of the adrenal glands. These hormones are released in response to stress and play a key role in regulating metabolism, immune response, and inflammation in the body.
What are adrenal glands responsible for?
They release hormones (three different kinds) in response to stress.
