The average nipple–to–sternal notch measurement in a youthful, well-developed breast is 21-22 cm; an equilateral triangle formed between the nipples and sternal notch measures an average of 21 cm per side. View chapter Purchase book. Sensory innervation of the breast is dermatomal in nature. The nipple should lie above the inframammary crease and is usually level with the fourth rib and just lateral to the midclavicular line. This rich blood supply allows for various reduction techniques, ensuring the viability of the skin flaps after surgery. Its vascular supply is derived equally from the lateral thoracic artery and from branches of the thoracodorsal artery. Found between the two muscles are the lateral pectoral nerve and the pectoral branches of the thoracoacromial artery.. The medial pectoral nerve supplies motor innervation to the pectoralis major muscle, and 40% of the time it wraps around the lateral border of the pectoralis minor muscle. In addition, with the onset of menopause (ie, decrease in estrogen levels), the relative amount of fatty tissue increases as the glandular tissue diminishes. Diagnosis is generally made clinically and is confirmed with MRI studies. [2]. It contains four muscles that exert a force on the upper limb: the pectoralis major, pectoralis minor, serratus anterior and subclavius. Supraclavicular nerves from the lower fibers of the cervical plexus also provide innervation to the upper and lateral portions of the breast.

It consists of a clavicular part and a sternal part, both converging to a flat tendon that inserts on the humerus. Anatomy, 2002 Pectoralis major and pectoralis minor muscles: Penetrates the clavipectoral fascia to supply the pectoralis major directly and, through communication with the medial pectoral nerve, the pectoralis minor. This handy volume has the aim of filling this gap by providing the information required by medical practitioners in rehabilitation, sports, and occupational health as well as by rehabilitation therapists, ergonomists, and sport coaches. Sternum. Treatment is usually surgical repair when presenting acutely. The external oblique muscle abuts the breast on the inferior lateral aspect.

This book has been considered by academicians and scholars of great significance and value to literature. Diagnosis is generally made clinically and is confirmed with MRI studies. This is an AAOS Self Assessment Exam (SAE) question. Pectoralis Major Muscle. The medial and lateral anterior thoracic nerves provide innervation for the muscle, entering posteriorly and laterally. Coverage of hot topics includes new implant types, gel implants, fat injections to the breast for aesthetic enhancement, and fat injections for reconstruction.The book is organized into seven sections including reduction, mastopexy, ... The tail of Spence extends obliquely up into the medial wall of the axilla. Once the fascia is elevated and released, proper positioning and expansion of the implant can proceed. The rectus abdominis muscle demarcates the inferior border of the breast. A sublabral foramen or hole is simply separation of the labrum from the underlying glenoid.It is a labral variant of no clinical significance and can be confused with a SLAP lesion.. Sublabral foramen are located anterosuperiorly and can extend down to but not below the 3 o'clock position, which divides the anterior labrum into superior and inferior halves. External Intercostals. When the breasts are carefully examined, significant asymmetries are revealed in most patients. Share cases and questions with Physicians on Medscape consult. [2], The breast overlies the pectoralis major muscle as well as the uppermost portion of the rectus abdominis muscle inferomedially. Pectoralis major. He has weakness in internal rotation but has good strength in external rotation and abduction; his apprehension test is negative. Because the serratus anterior underlies the lateral aspect of the breast, in aesthetic surgery, blunt elevation of the pectoralis major laterally inadvertently elevates a small portion of the serratus muscle. Innervation. 2002 Clear definitions, concise explanations, and plenty of full-color illustrations make Clinical Anatomy For Dummies the most accessible book available to supplement your classroom texts. It is mainly derived from the anterolateral and anteromedial branches of thoracic intercostal nerves T3-T5. Its origin is the outer surface of the upper borders of the first through eighth ribs, and its insertion is on the deep surface of the scapula. Can be located on the deep surface of the pectoralis major. Found insideA comprehensive state of the art of surgical techniques, tissue-engineered nerve graft scaffolds, and their application in nerve regeneration, the advances in peripheral nerve repair and future perspectives will be discussed, including ... This book presents current evidence in an Enhanced Recovery Programme context, and provides a common sense approach to using the array of available analgesia techniques appropriately in major abdominal surgery. Diseases & Conditions, 2002 (SAE07SM.60) The action of the pectoralis major is to flex, adduct, and rotate the arm medially. There are 11 pairs of external intercostal muscles.

The pectoralis minor pulls the shoulder and shoulder blade down and aids with inspiration by lifting the upper ribs as you inhale. The muscle also provides additional tissue between implant and skin, thus decreasing palpability of the implant.
