Study Notes
Mammary Glands and Lactation
- The mammary glands are the primary structures involved in lactation.
Breast Surface Anatomy
- The breast is located on the anterior thoracic wall.
- The axillary tail, a smaller part of the breast, runs along the inferior lateral edge of the pectoralis major towards the axillary fossa.
- Mammary glands are present in both males and females, but are more prominent in females after puberty.
Nerve Fibers
- The nerves contain both sensory and autonomic nerve fibers.
- Autonomic fibers regulate smooth muscle and blood vessel tone.
Hormonal Regulation
- Lactation is regulated by the hormones prolactin and oxytocin.
- Prolactin and oxytocin are secreted from the pituitary gland.
Breast Biopsy
- There are different types of breast biopsy.
Explore the development of secondary sexual characteristics that are more prominent in females following puberty. Understand the physiological changes that occur in both males and females during this stage of development.
