What are first messenger molecules?
A first messenger hormone is essentially the first hormone in a line that will eventually produce an effect.
Do asteroid and steroid have the same etymology?
Yes and no. They both derive from an Indo-European root ster-, but there seem to be three entirely different such roots. The first ster- means stiff or hard, and is the root of steroid. Ster- 2 means spread, and is the root of strew and straw. Ster-3 means star and is the root of star and asteroid.
Which planet is called messenger of Roman gods?

How many types of hormones secreted through testis?

What is Mercurys history?
Mercury, named for the Roman gods' messenger, is the closest planet to the and the smallest in the solar system. Mercury is too much in line with the Sun to be observed against a dark sky; therefore it is always seen during morning or evening twilight.

What is the link between a first messenger and a second messenger in a cell that responds to peptide hormones?

Steroid hormones exert their action by?
steroid hormones can pass easily through the plasma membrane, the hormones then bind to intracellular receptors which induce a metabolic pathway which later promotes transcription of a specific gene.
When were Androgens first discovered?
Also known as androgenic hormone or testoid, androgen was first discovered in 1936. Androgen is a generic term for steroid hormones such as testosterone.
How do peptide hormones exert action?
The peptide hormone is used to include hormones that are peptides,proteins,glycoprotein,and modified amino acids. peptide hormones binds to a receptor protein in the target cell's plasma membrane; a realy system leads to conversion of ATP to cAMP(cyclic adenosine mono phosphate).peptide hormones are the first messenger and cAMP and calcium are the second messengers. peptide hormones does not enter the cell; second messenger sets an enzyme cascade in motion.
Is FSH steroid or hormone?
First off, steroids and hormones are not mutually exclusive groups. The term "steroid" reflect a molecule's chemical structure -- all steroids share the same chemical backbone of cholesterol, which is why they are placed in the same group. The term "hormone" refers specifically to the molecule's function. A hormone is any chemical signal that travels via the bloodstream. Its chemical structure can be that of a steroid (hence we often talk about steroid hormones), it can be a protein or small peptide (hence protein and peptide hormones), or it can be in another class altogether (such as the catecholaminergic hormones like adrenaline and noradrenaline). Follicle-stimulating hormone (FSH) is secreted in the bloodstream by the pituitary gland and signals events to occur in distant target organs; thus FSH is a hormone. However, it is made of many amino acids strung together; thus FSH is a protein. So FSH is a protein hormone. Hope that helps.
