Question

Which of the following isn't technically a bone?

1) a teeth
2) patellae
3) sternum
4) phalanges

Answer 1

The teeth, represented by option 1, are not technically bones. They are part of the dental system and serve a different function.

Step-by-step explanation:

The teeth, represented by option 1, are not technically bones. Although they are hard and made of calcified tissue, they are not classified as bones because they are not part of the skeletal system. Instead, teeth are part of the dental system and serve a different function.

Answer 2

Among the options, a teeth (option 1) isn't technically a bone.

Step-by-step explanation:

Teeth are not considered bones in the anatomical sense, although they share some similarities. While both teeth and bones contain calcium, phosphorus, and collagen, teeth have a distinct composition and structure. Teeth are made of dentin, enamel, and pulp, and they serve a specialized function in biting and chewing food. In contrast, bones, such as the patellae (kneecaps), sternum (breastbone), and phalanges (finger and toe bones), form the skeletal framework of the body. The patellae protect the knee joint, the sternum supports the ribcage, and the phalanges contribute to the structure of the fingers and toes.

Option 1 is the answer, correctly identifying teeth as the structure that isn't technically a bone among the given options.
