Study Notes
Functions of Hormones
- Hormones are chemical messengers that help regulate various bodily functions, such as growth and development, metabolism, and reproductive processes.
Sources of Hormones
- Hormones are secreted by endocrine glands, which are ductless glands that release hormones directly into the bloodstream.
Target Organs for Hormones
- Hormones travel through the bloodstream to reach their target organs or tissues, where they exert their effects.
Changes in Tissue Metabolism
- Changes in tissue metabolism are caused by hormonal imbalance or fluctuations, which can affect growth, development, and overall health.
Follicle-Stimulating Hormone (FSH)
- The anterior pituitary gland releases follicle-stimulating hormone (FSH), which plays a crucial role in reproductive processes.
Types of Glands
- Endocrine glands, also known as ductless glands, discharge their secretions directly into the bloodstream.
- Examples of endocrine glands include the pituitary gland, thyroid gland, and adrenal glands.
Pituitary Gland
- The pituitary gland is located at the base of the brain and consists of an anterior lobe and a posterior lobe.
- The anterior pituitary gland regulates the function of other endocrine glands and produces several hormones that stimulate other glands.
Main Endocrine Glands
- The main endocrine glands in the body include the pituitary gland, thyroid gland, adrenal glands, pancreas, and gonads (ovaries and testes).
Master Hormone
- The hormone that controls other glands or acts on other tissues and is secreted by the anterior pituitary gland is often referred to as the "master hormone".
Regulation of the Endocrine System
- The negative feedback system regulates the endocrine system, similar to how a thermostat regulates temperature in a room, to maintain hormonal balance and prevent excessive hormone production.
