Question

Identify the numbered structures 

The image depicts the anatomy of the human arm, highlighting various muscles and tendons. There are three views shown: 1. **Top Left**: A close-up view of the elbow joint displaying surrounding muscle and tendon structures. The muscles are shaded in red, and the tendons are highlighted in blue. 2. **Center Bottom**: Displays a frontal view of the forearm including the elbow down to the wrist. The muscles here are again marked in red, and the tendons leading into the fingers are colored in blue. Labels indicate specific muscles: - **3**: Muscle in the upper forearm near the elbow. - **4**: A muscle located more towards the middle to lower forearm. - **5**: Tendons extending from the forearm into the hand. 3. **Right**: A side view of the arm, showing bones from the elbow to the hand, with muscles and tendons similarly marked. The labels identify: - **1**: A muscle located near the elbow. - **2**: A muscle positioned around the middle of the forearm. The bones of the arm are depicted in a creamy shade, providing a contrast to the colored muscles and tendons for better understanding of spatial relationships.

Expert Solution
Step 1

The given image is of posterior forearm muscles. Five muscles make up the deep layer of the forearm's posterior compartment; they are known as the deep posterior forearm muscles. The muscles in question are the abductor pollicis longus, extensor pollicis brevis, supinator, extensor pollicis longus, and extensor indices.
