Final answer:
The student's question is about the number of bones in the adult human skull, which consists of 22 bones. Twenty-one of these bones are immobile, while the 22nd bone, the mandible, is movable.
Step-by-step explanation:
The student is asking about the number of bones in the adult human skull. In an adult, the skull is made up of 22 individual bones. Twenty-one of these bones are fixed and do not move; they are fused together to form the main part of the skull. The 22nd bone is the mandible, or lower jaw, which is unique in that it is the only movable skull bone, allowing for functions like talking and chewing. Therefore, to answer the question, Teddy has exactly 22 bones in his skull, as do all normal adult humans.
