The hormones of the adrenal gland can act on the physiology of fear by intensifying it. Epinephrine is release when the body has a flight or fight response. This hormone increase heart rate, respiratory rate, and muscle contractions. Epinephrine also heightens the fear response in humans.

What is the name of the endocrine gland that secretes ACTH?
Adrenal Medulla is not the correct answer. The actual target of ACTH is the Adrenal Cortex, hence the name Adrenocorticotropic Hormone. Please feel free to test my answer, but I believe that is more specific than suggesting the Medulla itself.
What is Adrenocorticotropin?
A hormone that acts on cells of the adrenal cortex, causing them to produce male sex hormones and hormones that control water and mineral balance in the body.
What are 3 important glands in your body?
steroid hormones are the steroids which acts as a hormones.steroid hormones are nothing but the androgen,estrogen,progesterone and mineralocorticoids and glucocorticoids.ADRENAL GLAND;it is anatomically divided into 2 parts.adrenal medulla and adrenal cortex.again adrenal cortex contains following layers.zonaglomerulosa,zonafasiculata,and zona reticularis.zonaglomerulosa secretes mineralocorticoids.zonafasiculata secretes glucocorticoids.zonareticularis secretes androgen and estrogen .the principle mineralocorticoids is aldosteron while principle glucocorticoid is cortisol.while androgen are nothing but the testosterone and estrogen nothing the estrogen and progesterone.TESTIS;it secretes mainly testosterone which is a kind of androgen,.OVARY;it secretes mainly estrogen and progesterone also a kind of steroid hormones.these are in turn under control by anterior pituitary by F SH,LH,ACTH hormones.again these F SH,LH and ACTH are under control of hypothalamus by corticotrophin releasing hormone ,gonadotrophin releasing hormone.
What is adenalin?
Adrenaline is one of the body's hormone chemicals, in this case, secreted by the Adrenal Gland. Hormones are substances which (generally) cause other organs to increase their activity. In the case of Adrenaline, it acts to increase muscular strength, and is mainly responsible for the group of 'fight or flight' responses.
What is the growth hormones function in the pituitary gland?
It is made by the anterior pituitary gland and it doesn't have any function there. It acts on tissue away from the gland. Growth Hormone affects bones & muscles to produce growth.
ACTH stimulates the adrenal cortex to release corticosteroid hormones?
Yes. ACTH = AdrenoCorticoTropic Hormone. It acts on the Fasciculata and Reticulata areas of the adrenal cortex, stimulating the release of Glucocorticoids (Cortisol) and to a lesser degree, of weak Androgens.
Does ACTH act on the adrenal medulla?
No, it acts on the adrenal cortex
Which organs and tissues comprise endocrine system?
Nearly twenty organs and tissues have been discovered in Mammals and Human which secrete hormones and comprise endocrine system . Most of organs included in list are exclusively endocrine in nature while some organs perform other functions but also produce some hormones .Organs :1 : Adenohypophysis ( Anterior Pituitary Gland ) is considered master gland , produces 7 hormones2 : Neurohypophysis ( Posterior Pituitary Gland ) produces two hormones .3 : Pars inter-media ( Median lobe ) produces one hormone .4 : Hypothalamus is part of nervous system and also produces releasing and inhibiting hormones .5 :Thyroid , produces two hormones .6 : Parathyroid produces two hormones .7 : Islets of Langerhans ( Pancreatic islets ) , three hormones .8 : Adrenal cortex , many hormones .9 : Adrenal Medulla , two hormones .10 : Testes in males produce male sex hormones .!1 : Ovaries in females produce female sex hormones .12 : Pineal , one hormone .Tissues of Organs13 : Corpus Lute-um , one hormone .14 : Stomach produces gastrin15 : Duodenum produces secretin , motilin and C.C.K.16 : Heart produces a.n.p.17 : adipose tissue produces leptin .18 : Placenta produces many hormones .19 : Liver produces insulin like growth factor .20 : Thymus produces thymopoietin .
What are the functions of pituitary thyroid parathyroidpancreas and adrenal glands?
The adrenal glands (or suprarenal glands) are endocrine organs. As such, they produce and secrete various hormones. The adrenal glands are divided into a cortex and medulla. Within these separate areas, you will find varying hormones. Stress activated hormones are found in the medulla. These hormones are Epiniphrine and Norepiniphrine, or adrenaline and noradrenaline, respectively. These hormones are responsible for adapting the body to a flight or fight response. Various responsibilities of these hormones are increasing heart rate, causing bronchodilation, and redirecting blood flow by vasodilating and vasoconstricting in various areas of the body. These chemicals are present in the body as hormones and faster acting neurotransmitters in the nervous system. The cortex contains three groupings of hormones: minerocorticoids, glucocorticoids and androgens. The most abundant minerocorticoid is aldosterone. This hormone indirectly acts in water reabsorption by primarily reabsorbing Sodium (which water will follow). The main glucocorticoid is cortisol which acts as an anti-inflammatory (a form of cortisol is hydrocortizone which is the active ingredient of many anti-itch creams), and also acts as a glucose-saving hormone by promoting lipolysis (the breakdown of adipose tissue to be used as energy). Finally, androgens are more commonly thought of as steroid hormones such as Testosterone, DHT, DHEA, and the precursor to estrogens.
Why is the hypothalamus considered the control center of the endocrine system?
The hypothalamus is considered the control center of the endocrine system because it acts as the endocrine system's thermostat - it signals glands to turn on or off hormones as the body needs them.
How does zinc affect the immune system?
Zinc acts as an immune booster, in part due to stimulation of the thymus gland. This gland tends to shrink with age, and consequently produces less of the hormones that boost the production of infection-fighting white blood cells.
Does the skin act as a gland by synthesizing vitamin a?
Acts as a gland by synthesizing vitamin A.
