Name the structure

This image shows an anatomical illustration of the human muscular system, viewed from the back. The muscles are highlighted in red, indicating their anatomical positions, while other underlying areas are shown in grayish-white. The diagram includes several anatomical labels marked with numbers on various muscle areas. An arrow on the right side points to the hand, highlighting the tendons of the wrist and forearm.

The muscles visible in this diagram include:

- The trapezius and latissimus dorsi on the back.
- The deltoids and triceps on the upper arm.
- Various muscles and tendons of the forearm and hand are indicated, emphasizing the flexor tendons.

The labeled areas likely correspond to specific muscle names, as implied by the text located at the bottom left which reads, “A. Palmaris longus.” This suggests that the image may be part of a series or text explaining muscle anatomy more in-depth.

This type of illustration is typically used in educational settings to teach students about the muscular system and the specific locations and functions of different muscles.

The image displays a multiple-choice question related to anatomical terms, specifically muscles in the human body. The options provided are:

- A. Palmaris longus
- B. Flexor carpi radialis
- C. Flexor digitorium superficialis
- D. Biceps brachii
- E. Flexor carpi ulnaris

Expert Solution

Step 1 Muscles of the forearm:

A. Palmaris Longus: The origin of Palmaris Longus is from the medial epicondyle of the humerus. The insertion is into the palmar aponeurosis and flexor retinaculum. The nerve supply is from the median nerve.

C. Flexor digitorum superficialis: It is an extrinsic flexor muscle of the fingers at the proximal interphalangeal joints. The nerve supply is from the median nerve and the insertion is into anterior margins on the base of the middle phalanges of the four fingers. It acts to flex the fingers.

D. Biceps brachii: It is one of the main muscles of the upper part of the forearm which acts on both the shoulder joint and elbow joint.

E. Flexor carpi ulnaris: This is also the muscle of forearm but is not centrally placed, it is found on the lateral side to the Flexor carpi radialis. It flexes and adducts at the wrist joint.
