073 The Bones And Joints Of The Shoulder Girdle

In this video, Leslie Samuel discusses the bones and joints of the shoulder girdle. The video covers the three main bones: the clavicle, scapula, and proximal humerus, and the three joints: the sternoclavicular, acromioclavicular, and glenohumeral joints. Each section provides detailed explanations and visual aids to help understand the anatomy and significance of these structures. The video concludes with a review quiz to reinforce learning.

Which of the following bones is not part of the shoulder girdle?

• Femur

• Clavicle

• Scapula

• Proximal Humerus

Which bone is also known as the collarbone?

• Sternum

• Humerus

• Clavicle

• Scapula

What is the primary function of the sternoclavicular joint?

• Supports the acromion process

• Connects the clavicle to the scapula

• Connects the upper extremities to the trunk

• Allows rotation of the humerus

The acromioclavicular joint is formed by the articulation of the clavicle with which part of the scapula?

• Spine of the scapula

• Acromion process

• Glenoid fossa

• Coracoid process

What is the role of the acromion process in the shoulder girdle?

• It articulates with the proximal humerus

• It supports the sternum

• It forms a joint with the clavicle

• It connects the humerus to the scapula

Which joint involves the head of the humerus and the glenoid fossa?

• Glenohumeral joint

• Acromioclavicular joint

• Elbow joint

• Sternoclavicular joint

What is the significance of the glenohumeral joint?

• It connects the clavicle to the sternum

• It supports the weight of the head

• It allows a wide range of motion for the arm

• It stabilizes the scapula
