Why do you think some bones, such as the humerus and femur, have rounded ends? Why do you think other bones, such as the vertebr
alekssr [168]

Answer:

1. Their rounded shape allow them to joint properly with other bones, permitting a softer, better motion.

2. Provide protection for specific organs and their shape provides a broad surface for the proper attachment of muscles.

Explanation:

The bone is a <u>connective tissue composed of specialized cells, a mineral-salt matrix, and collagen fibers</u>. The main functions of the bones are <em>organ protection, structure, red and white blood cell production and support.</em>

There are different types of bones:

  • Long
  • Short
  • Flat
  • Sesamoid
  • Irregular
  • Sutural

Some bones, such as the humerus and femur, are characterized by their rounded ends, also known as <em>epiphyses </em><em>(epiphysis - singular)</em>. The reason behind epiphyses is joint function. These bones are long bones, and their rounded shape allow them to ajoint properly with other bones, permitting a softer, better motion.

On the other hand, flat bones, such as vertebrae and carpals, provide protection for specific organs and their shape provides a broad surface for the proper attachment of muscles.
