Consider the following statements: Femur is the longest bone in human ...
Longest bone in the human body:
The statement "Femur is the longest bone in the human body" is correct. The femur, also known as the thigh bone, is the largest and longest bone in the human body. It extends from the hip joint to the knee joint and plays a crucial role in supporting the weight of the body and facilitating movement.
Absence of sternum in fish:
The statement "Sternum is absent in fish" is also correct. The sternum, commonly known as the breastbone, is a flat bone located in the middle of the chest in humans and other mammals. It serves as an attachment point for the ribs and protects vital organs such as the heart and lungs. However, fish do not possess a sternum.
Explanation:
1. Femur as the longest bone: The femur is indeed the longest bone in the human body. It is a strong and sturdy bone that provides support and stability to the lower extremities. Its length and structure allow for the efficient transmission of forces during activities such as walking, running, and jumping.
2. Absence of sternum in fish: Fish belong to a different class of vertebrates called "Osteichthyes." Unlike mammals, fish do not possess a sternum. Their skeletal structure is adapted to their aquatic environment, and their bodies are supported by a combination of cartilage and bones. The absence of a sternum in fish is due to their evolutionary divergence from mammals.
Concluding statement:
In conclusion, both statements are correct. The femur is indeed the longest bone in the human body, while the sternum is absent in fish. These anatomical differences reflect the diverse adaptations and evolutionary paths taken by different species.
