Question

Which of the following parts of the vertebrate body arises from the mesoderm?

• A. Spinal cord
• B. Bony skeleton
• C. Epidermis
• D. Lens of the eye

Answer 1

The correct option is B Bony skeleton

• The vertebrates are the organisms which are triploblastic in nature. The body organs are made from the three germ layers.
• The bony skeleton is derived from the mesoderm layer. The different forms of mesoderm develop in different tissues.
• The Chordata mesoderms develop the notochord. The paraxial mesoderm gives rise to cartilage and skeletal tissues like the bones and muscles.
• The connective tissues are also derived from the mesoderm.

Thus, the correct answer is option B.
