Humerus und Scapula

The tutorial explores shoulder dislocation, contrasting its portrayal in media with reality. It delves into the anatomy of the shoulder joint, focusing on the humerus and scapula, and discusses their structures and interactions. The video also covers the ligaments that stabilize the shoulder joint and examines clinical approaches to treating shoulder dislocation, including the Cunningham method. The tutorial concludes with a summary of the key anatomical features and treatment insights.

What are the two bones primarily involved in forming the shoulder joint?

• Clavicle and Sternum

• Humerus and Scapula

• Femur and Tibia

• Radius and Ulna

Which part of the humerus articulates with the scapula?

• Trochlea

• Head of the Humerus

• Capitulum

• Tubercle Majus

What is the function of the deltoid tuberosity on the humerus?

• Attachment for the deltoid muscle

• Articulation with the ulna

• Support for the radial nerve

• Connection to the clavicle

Which structure divides the posterior surface of the scapula?

• Coracoid Process

• Spina Scapula

• Acromion

• Glenoid Cavity

What is the primary role of the rotator cuff muscles?

• To protect the rib cage

• To stabilize the humeral head

• To support the spinal column

• To connect the scapula to the clavicle

Which ligament connects the coracoid process to the clavicle?

• Glenohumeral Ligament

• Ligamentum Teres

• Coracoacromial Ligament

• Coracoclavicular Ligament

What is the main function of the glenohumeral ligaments?

• To support the clavicle

• To reinforce the joint capsule of the shoulder

• To connect the scapula to the rib cage

• To stabilize the elbow joint

What is the Cunningham method used for?

• Stabilizing the scapula

• Repairing torn ligaments

• Treating fractures of the humerus

• Reducing anterior shoulder dislocation

Which muscles are massaged in the Cunningham method?

• Infraspinatus, Teres Minor, and Subscapularis

• Trapezius, Deltoid, and Biceps Brachii

• Pectoralis Major, Latissimus Dorsi, and Triceps

• Serratus Anterior, Rhomboids, and Levator Scapulae

What is the primary goal of shoulder joint reduction?

• To increase shoulder mobility

• To prevent future dislocations

• To realign the humeral head into the joint socket

• To strengthen the rotator cuff
