The primary effector creates a signal that can diffuse within the cell. This signal is called the "secondary messenger." (The neurotransmitter is the first messenger.) The secondary messenger may then activate a "secondary effector" whose effects depend on the particular secondary messenger system.
Hormones are signaling molecules secreted by glands into the bloodstream to target distant cells, while secondary messengers are molecules produced inside cells in response to hormone signaling, amplifying and transmitting the signal to the cell's interior. Hormones act at a distance, while secondary messengers act within the cell to relay and amplify signaling.

Define the difference between primary and secondary endocrine pathology?
Primary endocrine pathology refers to dysfunction within an endocrine gland itself, causing abnormal hormone production. Secondary endocrine pathology results from dysfunction in the pituitary gland or hypothalamus, leading to inadequate stimulation or suppression of hormone production in the target endocrine gland.
What is the combination of endocrine gland and hormone?
The combination of an endocrine gland and a hormone is a working endocrine gland that has a chemical messenger called a hormone. The hormone can be either manufactured by that gland itself, a stored hormone that another gland made, or it can be a positive or negative feedback hormone as part of the hormonal control system.
What Messenger molecule carries instructions from its host organ to other cells in the body is known as a?
Hormone.
What is the link between a first messenger and a second messenger in a cell that responds to peptide hormones?
Peptide hormones bind to cell surface receptors, activating signaling pathways that involve the generation of second messengers within the cell. The first messenger (peptide hormone) triggers the activation of specific proteins or enzymes that then generate the second messenger molecules, such as cyclic adenosine monophosphate (cAMP) or inositol trisphosphate (IP3), initiating a cascade of cellular responses.
What is the hormone produced by the testes?
The primary hormone produced by the testes is testosterone, which plays a crucial role in male reproductive tissues and secondary sexual characteristics.
Why is cyclic AMP a secondary messenger?
because original message is carried by hormone, which cant act directly, so in turn it activates cyclic AMP.
What is the difference between a gland and hormone?
AYYO
Define the difference between primary and secondary endocrine pathology?

Secondary endocrine pathology results from dysfunction in the pituitary gland or hypothalamus, leading to inadequate stimulation or suppression of hormone production in the target endocrine gland.
What is the hormone that causes secondary characteristics in males?
Testosterone, the male hormone.
A word that means chemical messenger?
hormone or neurotransmitter
What is an example of a chemical messenger?
An example of a chemical messenger is a hormone, such as insulin or adrenaline, which is produced by glands in the body and travels through the bloodstream to target cells to regulate various physiological processes.
A chemical messenger involved in the regulations of body functions is a what?
blood
Which hormone assumes a role in the development and discharge of a secondary oocyte?
The hormone that plays a crucial role in the development and release of a secondary oocyte is luteinizing hormone (LH). It is released by the pituitary gland and triggers ovulation, the process by which the mature ovarian follicle releases the secondary oocyte.
What is the male development secondary characteristics stimulated by?
The most prominent hormone involved in secondary sex characteristics for a male is testosterone.
What type of hormone does NOT require a messenger to move it across the cell membrane?
adh
What chemical is produced in one part of an organism and transported to another part where it causes a physiological change?
i think it mostly effect on reptiles.
A hormone involved in secondary sex characteristics in males?
Testosterone
