Question

1.1.4: looking inside bone - bone’s unique structure and upon closer examination
introduction
bones are a remarkable example of engineering, combining lightness, flexibility and incredible strength. bone provides a tough, flexible frame for the human machine. pound for pound, bone is actually stronger than concrete. but remember, bone is living tissue. cells and protein fibers are wrapped inside layers of hard mineral salts. these cells are hard at work, constantly remodeling and replacing old or damaged bone. blood vessels and nerves bring needed nutrients and signals to the cells in this hard matrix. all of these structural components allow bone to withstand tremendous amounts of stress and protects the internal organs from damage and injury.
types of bones

bone type	description and sketch of structure	examples of these bones in the human body
short bone
flat bone
irregular bone

label the following correctly according to their bone type. find these examples and color code them on your manikin.
metacarpals
sternum
vertebra

Explanation:

Long bones are longer than they are wide and are involved in movement, such as the metacarpals in the hand. Short bones are cube - shaped and provide stability and support, like some wrist and ankle bones (though not specifically asked here). Flat bones are thin and provide protection and muscle attachment, such as the sternum. Irregular bones have complex shapes and functions, like the vertebrae.

Answer:

• Metacarpals: Long bone
• Sternum: Flat bone
• Vertebra: Irregular bone
