Understanding the Proximal Humerus

What is the primary focus of this video?

• The function of the shoulder girdle

• The structure of the proximal humerus

• The physiology of the biceps

• The anatomy of the entire arm

How can you determine if a humerus is from the left or right side?

• By measuring the length of the bone

• By checking if it projects laterally

• By examining the color of the bone

• By ensuring the head points superiorly, posteriorly, and medially

What is the name of the groove located between the greater and lesser tubercles?

• The deltoid groove

• The humeral groove

• The bicipital groove

• The radial groove

What are the three facets found on the greater tubercle?

• Superior, middle, and inferior

• Anterior, posterior, and lateral

• Proximal, distal, and central

• Medial, lateral, and distal

What is the function of the intertubercular groove?

• To house the tendon of the long head of the biceps

• To provide a site for bone growth

• To support the deltoid muscle

• To connect the humerus to the scapula

Which of the following is a common site for fractures in the humerus?

• The surgical neck

• The anatomical neck

• The deltoid tuberosity

• The greater tubercle

What is the anatomical neck of the humerus?

• The distal end of the humerus

• The area between the humeral head and tubercles

• The groove for the biceps tendon

• The site of muscle attachment

What is the significance of the surgical neck?

• It is a common site for muscle attachment

• It is a frequent site of fractures

• It is the distal end of the humerus

• It is the location of the bicipital groove

What is the deltoid tuberosity?

• A type of bone fracture

• A part of the shoulder joint

• A projection for muscle attachment

• A groove for the biceps tendon

What is the crest of the greater tubercle also known as?

• The superior lip

• The lateral lip

• The inferior lip

• The medial lip
