Question

Write the names of two bones in the upper arm?​

Answer 1

Ulna, Radius are the names of two bones in the upper arm.

Answer 2

Ulna

• The medial bone of the forearm is known as the ulna. It follows the radius, the lateral bone of the forearm.
• On the proximal end of the ulna, the conspicuous C-shaped trochlear notch looks like a crescent wrench.
• The trochlear notch's inferior margin is formed by the ulna's coronoid process.
• Just underneath this is the ulnar tuberosity, which is a roughened area on the anterior ulna.

Radius

• On the forearm's lateral (thumb) side, the radius runs parallel to the ulna.
• A disc-shaped structure termed the head is found at the radius's proximal end.
• The capitulum of the humerus articulates with the little depression on the head's surface as part of the elbow joint.
