Question

Identify the numbered structures 

This image depicts detailed anatomical diagrams of the human forearm and hand, highlighting muscle and tendon structures. ### Diagram Explanation: 1. **Left Diagram:** - **Label 6:** Indicates a large muscle on the anterior forearm. This could represent the flexor muscles responsible for bending the wrist and fingers. - **Label 7:** Points to the tendons extending into the fingers, likely representing the flexor tendons that aid in finger movement. 2. **Middle Diagram:** - **Label 8:** Highlights a muscle located deeper within the forearm, possibly showcasing the intermediate or deep flexor muscles. 3. **Right Diagram:** - **Label 9:** Shows a prominent muscle along the lateral side, potentially illustrating the extensor muscles which function to extend the wrist and fingers. - **Label 10:** Directs attention to the distal tendons reaching the fingers, likely indicating extensor tendons. ### General Structure: - The diagrams illustrate the skeletal components of the forearm and hand, including the radius and ulna, as well as the carpal, metacarpal, and phalangeal bones. - The highlighted muscles and tendons demonstrate the complex arrangement necessary for the fine motor functions of the hand. This depiction serves as a fundamental resource for understanding the musculoskeletal anatomy and function of the human forearm and hand.

Expert Solution
INTRODUCTION::

Muscles in the anterior compartment of forearm are divided into three layers as superficial, intermediate and deep. This muscle groups in the anterior compartment of forearm are associated with the pronation of forearm, flexion of the wrist and flexion of the fingers. These muscles are innervated by median nerve and ulnar nerve. They receive arterial supply from ulnar artery and radial artery.
