Classify the bones in the following diagram according to their shape.
c. _____

Verified step by step guidance

1. Step 1: Identify the bone labeled 'c' in the diagram. It is the long bone shown on the left side of the skeleton, which appears to be a femur or humerus.
2. Step 2: Recall the classification of bones by shape: Long bones are longer than they are wide and primarily function as levers; examples include femur, humerus, and tibia.
3. Step 3: Compare the shape of the bone labeled 'c' to the characteristics of long bones. It has a shaft (diaphysis) and two ends (epiphyses), which is typical of long bones.
4. Step 4: Confirm that the bone labeled 'c' fits the criteria of a long bone based on its elongated shape and structure.
5. Step 5: Conclude that the bone labeled 'c' should be classified as a long bone.

Key Concepts

Bone Classification by Shape

Bones are classified into four main shapes: long, short, flat, and irregular. This classification is based on their shape and structure, which relates to their function in the body. For example, long bones are longer than they are wide and primarily support weight and facilitate movement.

Long Bones

Long bones, such as the femur shown in the image, are characterized by a shaft and two ends. They are mostly found in the limbs and are crucial for movement and support. Their length allows for leverage and strength in activities like walking and lifting.

Flat and Irregular Bones

Flat bones, like the parietal bone in the skull, provide protection and a broad surface for muscle attachment. Irregular bones, such as vertebrae, have complex shapes that do not fit other categories and serve specialized functions like protecting the spinal cord and supporting body structure.
