Allow the attachment of various muscles and ligaments

Question 18

What is humerus

Answer 18

Is the longest and largest bone of the upper limb which extends from shoulder to elbow

Greater and Lester tuberosity
Radial and coronoid fossa
Medial and lateral epicondyle
Capitulum and trochlea
Deltoid tuberosity
Bicipitak groove

Question 22

Explain greater and lesser tuberosity

Answer 22

Greater is consist of three smooth and flat impression at the posterosuperior aspect for the attachment of roraroe cuff muscles
Lessrer it provides attachment for tge subscapularis

Question 23

Explain radial and coronoid fossa

Answer 23

Radial. Named as the margin of the head of the radius lodges there full flexion
Coronoid. During flexion of the elbow it’d lodges into the coronoid fossa

Question 24

Explain lateral and medial epicondyle

Answer 24

Lateral. The Common extensor origin for muscle of the posterior forearm
Medial. The common flexor origin for muscle of the anterior forearm

Question 25

Explain capitulum and trochlea

Answer 25

Capitulum. Articulate with the head of radius Trochlea . Articulate with trochlear notch of the ulna

Question 26

Explain deltoid tuberosity and bicipital groove

Answer 26

Deltoid. Roughened v shaped region located laterally on the mid-shaft of the humerus’s Bicipital groove. Narrow groove located btw greater and lesser tubercles of the humerus

Question 27

Posterior view of humerus

Answer 27

Head of the humerus: it articulate with the glenoid fossa of the scapula Anatomical neck: the site of attachment of the joint capsule Surgical neck: found inferior to the head of humerus Radial groove: radial deep brachial artery Olecranon fossa: is deep hollowed area on the posterior surface, superior to the trochlea Groove for ulnar nerve: where the ulnar nerve runs

Question 28

Radius

Answer 28

Is lateral and shorter of the two forearm bones and is long bone in forearm

Question 29

What is the proximal end of the radius and distal end

Answer 29

Proximal: has head which articulates with both the distal humerus and the proximal ulna Distal: articulate with the head of the ulna and carpal bone at wrist
