Living anatomy

Skin and living anatomy

Skin is lax and it has Langer's lines which run transversely.

Superficial fascia.

This is expanded to accommodate the mammary gland in the female. In other areas of the pectoral region it may not be fully developed, especially in the male.

Deep fascia

This is called pectoral fascia and it accommodates the pectoralis major which is the main muscle in the pectoral region. It also gives attachment to the ligaments which help to support the female breast especially in the nulliparous (no child) woman. This fascia is continuous above with the deep investing fascia of neck and below it is continuous with the membranous superficial fascia of the anterior abdominal wall. It is pierced by numerous cutaneous vessels and nerves.
