Endocrine vs Exocrine Glands Quiz

Endocrine System and Hormones

• Synthetic hormones like RU486 can block natural hormone receptors, affecting normal functions
• Hormones need receptors to perform their functions; excessive hormones can deactivate receptors
• Target cells with receptors for specific hormones are activated when the hormone is present
• The hypothalamus serves as a link between the nervous and endocrine systems
• The hypothalamus regulates various bodily functions and is also classified as an endocrine gland
• The pituitary gland consists of the anterior and posterior lobes, each with distinct functions
• The anterior pituitary gland controls a wide range of bodily activities and is regulated by the hypothalamus
• Hormones secreted by the anterior pituitary gland include hGH, TSH, FSH, PRL, and ACTH
• Different types of cells in the anterior pituitary gland react to chemical staining in different ways
• The anterior pituitary gland secretes tropic hormones, which regulate the function of other endocrine glands
• The pituitary gland secretes tropic hormones like TSH, ACTH, FSH, and LH, which regulate the ovaries and testes
• The pituitary gland plays a crucial role in regulating growth, reproduction, metabolism, and homeostasis

The Endocrine System: Key Concepts and Functions

• Synthetic hormones like RU486 (mifepristone) can block the receptors for naturally occurring hormones, such as progesterone, and prevent their normal effects, as seen in abortion induction.
• Hormones exert their effects by interacting with specific receptors on target cells, with each cell typically having 2000 to 100,000 receptors for a specific hormone.
• The hypothalamus, classified as an endocrine gland, serves as a vital link between the nervous and endocrine systems, controlling various bodily functions and receiving signals from internal organs and the retina.
• The pituitary gland, comprising the anterior and posterior lobes, plays a crucial role in regulating numerous bodily activities, from growth to reproduction.
• The anterior pituitary, representing 75% of the gland, releases hormones that control various bodily functions, and its secretion is regulated by the hypothalamus through the hypothalamic-hypophyseal portal system.
• Hormones released by the anterior pituitary include human growth hormone (hGH), thyroid-stimulating hormone (TSH), follicle-stimulating hormone (FSH), and prolactin, each with specific functions in the body.
• The anterior pituitary consists of five types of cells: somatotrophs, thyrotrophs, gonadotrophs, lactotrophs, and corticotrophs, which can be grouped based on their reaction to chemical staining.
• The anterior pituitary releases tropic hormones, including TSH, ACTH, FSH, and LH, which regulate the function of other endocrine glands such as the thyroid, adrenal cortex, and gonads.
• The thymus, pancreas, pituitary, testes, and ovaries are exclusively endocrine glands, while the placenta, kidney, sudoriferous glands, and mucous glands have other primary functions.
• Hormones have a significant impact even in small doses, acting only on cells with specific receptors for the hormone, and the number of receptors on a cell can adjust based on the hormone's concentration.
• The hypothalamus, functioning as the "boss" of the pituitary gland, controls the release of hormones from the pituitary and is crucial in coordinating various bodily functions.
• The pituitary gland, located in the sella turcica of the sphenoid bone, is connected to the hypothalamus and consists of distinct functional and anatomical divisions, the anterior and posterior lobes.
