On the educational website, the following text can be used to describe the image: --- ### Anatomy of the Arm and Elbow Joint **Diagram Explanation:** This image illustrates the anatomy of the arm, specifically focusing on the elbow joint. Below is a detailed explanation of the key components highlighted in the diagram: 1. **Arrow (Red and Blue):** - A red arrow indicates the pathway of blood flow through the arteries to the lower arm. - A blue arrow indicates the venous return pathway back towards the heart. 2. **Bicep Muscle:** - The bicep muscle, a crucial muscle in the upper arm, is shown contracting, which assists in the flexion of the elbow joint. 3. **Bones:** - The humerus (upper arm bone) is connected to the radius and ulna (forearm bones) at the elbow joint. 4. **Nerves:** - The diagram also highlights the presence of nerves running along the arm, essential for transmitting signals from the brain to facilitate movement and sensation. 5. **Tendons and Ligaments:** - Tendons connecting the muscles to the bones are essential for movement. - Ligaments shown in the diagram stabilize the elbow joint by connecting bones together. 6. **Elbow Joint:** - The hinge joint, where the humerus connects to the radius and ulna, facilitates bending and straightening of the arm. 7. **Skin and Tissue Layers:** - The image shows the exterior layer of skin and the underlying tissues, including fat and connective tissue. 8. **Note (g):** - A small 'g' notation can be observed in the lower arm region indicating the position, probably relating to a specific muscle or anatomical landmark. --- This diagram is essential for understanding the basic anatomy and function of the human arm and elbow joint. It serves as an invaluable resource for students and educators in the fields of biology, medicine, and physiology.

Question
In an isometric exercise a person places a hand on a scale and pushes vertically downward, keeping the forearm horizontal. This is possible because the triceps muscle applies an upward force M perpendicular to the arm, as the drawing indicates. The forearm weighs 24.0 N and has a center of gravity as indicated. The scale registers 103 N. Determine the magnitude of M.

### Anatomy of the Arm and Elbow Joint
**Diagram Explanation:**
This image illustrates the anatomy of the arm, specifically focusing on the elbow joint. Below is a detailed explanation of the key components highlighted in the diagram:
1. **Arrow (Red and Blue):**
- A red arrow indicates the pathway of blood flow through the arteries to the lower arm.
- A blue arrow indicates the venous return pathway back towards the heart.
2. **Bicep Muscle:**
- The bicep muscle, a crucial muscle in the upper arm, is shown contracting, which assists in the flexion of the elbow joint.
3. **Bones:**
- The humerus (upper arm bone) is connected to the radius and ulna (forearm bones) at the elbow joint.
4. **Nerves:**
- The diagram also highlights the presence of nerves running along the arm, essential for transmitting signals from the brain to facilitate movement and sensation.
5. **Tendons and Ligaments:**
- Tendons connecting the muscles to the bones are essential for movement.
- Ligaments shown in the diagram stabilize the elbow joint by connecting bones together.
6. **Elbow Joint:**
- The hinge joint, where the humerus connects to the radius and ulna, facilitates bending and straightening of the arm.
7. **Skin and Tissue Layers:**
- The image shows the exterior layer of skin and the underlying tissues, including fat and connective tissue.
8. **Note (g):**
- A small 'g' notation can be observed in the lower arm region indicating the position, probably relating to a specific muscle or anatomical landmark.
