Around the Shoulder

The following set of cadaver dissection anatomy photo thumbnail images represent a layered tour of some of the fascia and musculature in the area around and relating to the shoulder.

skin intact, back of male cadaver skin removed revealing superficial fascia, back of male cadaver superficial fascia removed revealing deep fascia, back of male cadaver deep fascia, upper back of male cadaver, sectioned dowager hump deep fascia removed, superficial musculature of upper back of male cadaver defined identifying upper and lower termini of trapesius muscles reflecting left trapezius m. posteriorly revealing splenius capitus muscle reflecting and removing trapesius m. as a whole trapesius m. removed revealing fascia, latissimus dorsi m. and rhomboid muscles identifying left pectoralis major m. from posterior aspect deflecting teres major m. to reveal tendon of latisimus dorsi m. close view of latissimus dorsi tendon close view of ribbonlike tendon of latissimus dorsi reflected identifying serratus anterior from posterior aspect near inferior angle of scapula general view of rhomboid and latissimus dorsi muscles right pectoralis major identified from posterior view reflecting right latissimus dorsi muscle noting normal fascial adhesion of latissimus dorsi m. to underlying tissues incising normal fascial adhesion of latissimus dorsi m. to underlying tissues tissues underlying right latissimus dorsi m. continued reflection of right latissimus dorsi m. revealing underlying tissues differentiating right rhomboid major m. identifying right teres major muscle mobilizing scapula to reveal fascial relations at scapulothoracic interface identifying continuity of lower edge of rhomboid major m. with medial border of scapula differentiating loose connective tissue relations of right scapula to thorax differentiating right rhomboid major muscle furthering differentiation of right rhomboid major muscle by incising denser connective tissue relationships furthering differentiation of right rhomboid major muscle by incising denser connective tissue relationships supero-medially furthering differentiation of right serratus anterior muscle by incising denser connective tissue relationships inferio-laterally skin intact at thorax of male cadaver skin removed revealing superficial fascia at thorax of male cadaver superficial fascia removed revealing deep fascia at thorax of male cadaver deep fascia removed revealing superficial muscle layer at thorax of male cadaver anterior view of left pectoralis major and deltoid muscles in situ lateral view of left side of thorax and shoulder at muscle layer beginning reflection of left pectoralis major m. continued reflection of left pectoralis major m. into tendon at humeris revealing underlying tissues indicating continuity of pectoralis major and deltoid muscle tissues further indicating continuity of pectoralis major and deltoid muscle tissues reflecting left deltoid muscle while maintaining relationships with pectoralis major m. closer view of tissues underlying left pectoralis major and deltoid muscles displaying continuities of left pectoralis major and deltoid muscles off of body differentiating loose fascial relations deep to left pectoralis minor muscle reflecting left pectoralis minor m. revealing underlying tissues demonstrating undifferentiated left axillary tissue complex closer view of partly differentiated left axillary nervous and vascular bundles identifying and differentiating tendon of long head of left biceps brachii displaying ~triceps chorachoidius m.~, i.e. pectoralis minor, choracobrachialis and short head of biceps brachii muscles indicating thin tissues of anterior aspect of left shoulder joint capsule-rotator cuff lifting thin tissues of anterior aspect of left shoulder joint capsule-rotator cuff differentiating tendon of long head of right biceps brachii m. coming into shoulder joint capsule right shoulder joint capsule opened revealing humeral head identifying fully differentiated left rhomboid and serratus anterior muscles in their full continuity in situ displaying fully differentiated left rhomboid and serratus anterior muscles in their full continuity off body additional display of fully differentiated left rhomboid and serratus anterior muscles in their full continuity medio-lateral view of left scapula with extrinsic musculature reflected and removed leaving only rotator cuff muscles intact reflecting left scapula to reveal subscapularis muscle tissues lateral view of left scapula with extrinsic musculature reflected and removed leaving only rotator cuff muscles intact identifying left teres minor muscle identifying left infraspinatus muscle identifying left supraspinatus muscle
