Anatomy and Phisiology of the Breast
Course Objectives:
- Participants will be able to describe the general development of the female breast from the embryonic stage to the post lactation stage (involution).
- Participants will be able to describe how problems during embryonic and / or pubertal development may impact on a woman’s future lactation.
- Participants will be able to describe the structure of the normal lactating breast
- Participants will be able to discuss the physiology of lactation at the cellular and hormonal levels
- Participants will be able to describe the stages of lactogenesis.
- Participants will be able to list at least 3 techniques to maintain milk production
- Participants will be able to define and compare the endocrine vs autocrine control of milk synthesis.
- Participants will be able to identify common abnormalities of the breast which can affect lactation management
- Participants will be able to discuss with other members of the class, techniques to convey information learned in this course, in preparation for the IBLCE exam.
