mammary glands
Prolactin
The hormone involved in milk production is prolactin, which is produced by the anterior pituitary gland. Oxytocin is the hormone responsible for the ejection or release of milk from the mammary glands in response to suckling or stimulation of the nipples.
Hormones involved in lactation include prolactin and oxytocin. Prolactin stimulates milk production in the mammary glands, while oxytocin triggers the release of milk from the glands into the ducts for breastfeeding. These hormones work together to regulate the production and ejection of breast milk during lactation.
The pituitary gland is often referred to as the "master gland" because it regulates the production of hormones in other glands. It releases hormones that control activities in other endocrine glands, such as the thyroid, adrenal glands, and reproductive organs. The pituitary gland is located at the base of the brain and plays a crucial role in maintaining hormonal balance in the body.
Yes, endocrine glands secrete hormones directly into the bloodstream.
Endocrine glands typically do not have cilia. These glands are primarily involved in the secretion of hormones directly into the bloodstream and lack duct systems, differentiating them from exocrine glands that may have cilia for moving substances. Instead, endocrine cells are specialized for hormone production and release, relying on other mechanisms for cellular signaling and transport.
The mammary glands are the organs of milk production
The ejection of secretions from glands is primarily driven by a process called exocytosis, where vesicles containing the secretion fuse with the cell membrane, releasing their contents. This process is often triggered by specific stimuli, such as hormonal signals, neural inputs, or changes in the environment, which activate intracellular signaling pathways. Additionally, muscle contractions surrounding certain glands, like salivary or sweat glands, can aid in the expulsion of secretions. Overall, the coordinated action of biochemical signals and mechanical forces facilitates this ejection process.
salivary glands
An oily secretion from glands. Example: he has higher sebum production.

Ductless glands are glands that secrete there product directly onto a surface rather than through a duct.
