Question

The bones with similar length, width, depth are _____________.
A. Flat bones
B. Long bones
C. Short bones
D. None of these

Answer 1

Hint: These bones are almost cuboidal in shape and present in the wrist and ankle joint.

Step by step answer:
There are five types of bones: long bone, short bone, flat bone, irregular bone, and sesamoid bone.
-Short bones are roughly cube-shaped. They have a spongy interior and surrounded by a thin layer of compact bones. Their length, diameter, width, and depth all are the same. Short bones include the tarsals ( seven in number) in the foot and the carpals (eight in number) in the hand. These bones provide support and stability with little movement.

Therefore the correct answer is (C) short bones.

-Long bones consist of various parts like Diaphysis, Metaphysis, and epiphysis. The shaft of long bone i.e., diaphysis is much longer than its width and depth. Long bones are made up of compact bone, some amount of marrow in the medullary cavity, and cancellous bone at the ends of bones. Almost all the vertical bones in our body are long bones. Examples are humerus, femur, radius, ulna, etc.
-Flat bones are thin bones, making their width much shorter than their length. The examples of short bones are the skull and sternum.
-Sesamoid bones are bones embedded in tendons. Examples of sesamoid bones are patella and pisiform.
-Irregular bones: These types of bones consist of variable shapes. Their width, length, and depth are not equal. Just like short bones, they have a very thin layer of compact bones surrounding the spongy interior. Bones of the spine, pelvis, and few bones in the skull are irregular bones.

Note: Bones are of five types long bone (humerus, femur, radius, ulna, etc.), short bone (tarsals and the carpals), flat bone (skull and sternum), irregular bone (spine, pelvis, and few bones in the skull), and sesamoid bone (patella and pisiform).
