Endocrine glands release hormones (chemical messengers) into the bloodstream to be transported to various organs and tissues throughout the body. For instance, the pancreas secretes insulin, which allows the body to regulate levels of sugar in the blood.
What chemical does the endocrine release into the bloodstream?
The cells in these glands secrete specific chemicals called hormones . Hormones circulate around the body via the blood stream and modulate cellular or organ functions by binding with receptors in the target cells. Hormones that stimulate and control the activity of other endocrine glands are called trophic hormones.
What chemical messenger is released from endocrine glands into the bloodstream quizlet?
Hormones , the chemical messengers of the endocrine system, contact virtually all cells within the body. However, hormones affect only target cells, those cells with receptors that recognize and bind specific hormones.
Are chemicals released by endocrine glands into the bloodstream?
Endocrine glands make chemicals called hormones and pass them straight into the bloodstream. Hormones can be thought of as chemical messages. From the blood stream, the hormones communicate with the body by heading towards their target cell to bring about a particular change or effect to that cell.
What are the chemical messengers released?
Chemical messengers produced by nerve cells and released from the axonal endings usually act in endocrine or paracrine fashion. When the neural signalling molecules are released into the synaptic gap to activate receptors on the adjacent cell membranes, they are called neurotransmitters .
Which of the following is an example of a target gland in the endocrine system?
The Anterior Pituitary . The anterior pituitary produces several important hormones that either stimulate target glands (e.g., the adrenal glands, gonads, or thyroid gland) to produce target gland hormones or directly affect target organs.
Which endocrine gland is considered the master gland?
The pituitary gland is sometimes called the “master” gland of the endocrine system because it controls the functions of many of the other endocrine glands. The pituitary gland is no larger than a pea, and is located at the base of the brain.

What are the common endocrine glands of male and female?
The gonads are additional types of endocrine glands. They are the sex organs and include the male testes and female ovaries . Their main role is the production of steroid hormones.
What is the most common chemical messenger?
The most common neurotransmitter is acetylcholine , which often is the messenger between axons and muscles as well. Other common neurotransmitters are octopamine, serotonin, and dopamine; they usually function in the central nervous system.
