The prime focus of this sqadia.com medical lecture is scapular region and superficial back. This lecture elaborates various concepts including structure and bony landmarks alongside the superficial anatomy and orientation. Furthermore, muscular structure, movements of the scapula-thoracic articulation together with coupling rotator cuff and its stabilizing action has been expansively delineated.
Structure and Bony Landmarks
The objective of this section is structure and bony landmarks. In the start, scapula alongside both superior and inferior angles have been mentioned. Following this, vertebral and axillary border in conjunction with the spine and glenoid fossa has been discussed. Conclusively, coracoid and acromion processes have been highlighted.
Superficial Anatomy and Orientation
First and foremost, scapular region and superficial back surface anatomy is delineated. Following this, triangle of auscultation along with the bones and surface landmarks have been explained. Moreover, axillary folds, teres major muscle together with the orientation of the glenohumeral articular surfaces is shed light on. In the end, scapulothoracic articulation and spinal contribution to shoulder motion is talked about.
After conversing about scapular region and superficial back, trapezius muscle including upper, middle and lateral trapezius is highlighted. Moving ahead, serratus anterior, coupling of serratus anterior and Levator scapula. Additionally, rhomboid muscle and pectoralis minor is delineated.
Movements of Scapulothoracic Articulation
Initially, motion of scapulothoracic articulation along with the scapular movements are discussed. Furthermore, shoulder complex, scapulohumeral rhythm and motion of the scapulothoracic articulation have been comprehensively elaborated.
Coupling with Rotator Cuff
Primarily, rotator cuff muscles, scapular region together with the coupling of deltoid and oblique rotator cuff muscles is explained. Following this, coupling of deltoid and supari spinatus along with the stabilizing action of rotator cuff muscle is explicated.
