Adrenal Gland
There are three kinds of chemical messengers in the nervous system: Neurotransmitters, endorphins and hormones. 1) Neurotransmitters are released by transmitting neurons. They alter the activity of the receiving neurons. Note that neurotransmitters exist outside of the nervous system as well. Some neurotransmitters are: Serotonin, dopamine, acetylcholine, gamma-aminobutyric acid (GABA), norepinephrine (also a hormone) and glutamate. 2) Endorphins help in pain reduction, pleasure and even memory. 2) Hormones are affects the functioning of organs and are released by glands. Some hormones include: Melatonin, oxytocin, adrenal hormones (cortisol, epinephrine, norepinephrine) and sex hormones (androgens, estrogens and progesterone).
Some pituitary hormones have a negative
hydrophilic "water loving" Hormones 2 groups- -Peptides (short protein)- such as insulin - Catecholamines: hormones epinephrine and noreepinephrine Low lipid solubility, High water solubility Lipophilic "Fat Loving" Hormones 2 Groups - Thyroid hormones - Steroid Hormones --> sex hormones such as testosterone High lipid solubitilty, poorly soluble in water Cholesterol precusor (molecule is not a hormone)
Cholesterol is associated with fatty depostitions in the arteries which are associated with heart attacks and stroke. The basic idea is that reducing cholesterol intake with reduce the formation of these deposits. However, cholesterol is also important as building block for hormones in the body so complete elimination is problematic.
pheromones are special female hormones
Epinephrine & Norepinephrine (NE)
Adrenal glands
cat.e.cho.la.mine (kt-kl-mn, -kô-) n. Any of a group of amines derived from catechol that have important physiological effects as neurotransmitters and hormones and include epinephrine, norepinephrine, and dopamine.
epinephrine and norepinephrine
Adrenal medulla
The adrenal hormones epinephrine (also known as adrenaline) and norepinephrine.
The Adrenal Gland. This gland is divided into two categories, the Adrenal Cortex and the Adrenal Medulla. The Adrenal Medulla produced epinephrine and norepinephrine. Epinephrine is also known as adrenaline, and the beginning of the word, "adrenal", is the same name as the gland, The Adrenal Gland.
peptide hormones and catecholamines (epinephrine and norepinephrine)
norepinephrine, epinephrine and angiotensin II
epinephrine and norepinephrine are released by the adrenal glands
what are the medullary hormones You can't answer a question with a question...the medullary hormones (adrenal) they are referring to are epinephrine and norepinephrine.
Epinephrine and Norepinephrine. They're part of the "fight or flight" responses in one's body ultimately slowing down the body's urine production.
