Chapter 8, Problem 1CYR

Which of the following is not a function of articulations?

a. Movement

b. Blood cell formation

c. Stability

d. Providing growth in length for long bones

Summary Introduction

Introduction:

Articulations are the joints present between the skeletal system of an organism and the functional system. The region where bone and a cartilage join together. For example, the joint between the tooth and the jaw bone is an articulation, known as gomphosis. Articulations can be classified as monoarticular, oligoarticular, and polyarticular.

Answer to Problem 1CYR

Correct answer:

Creation of blood cells is not a function of the articulation of bones.

Explanation of Solution

Justification/explanationfor the correct answer:

Option (b) states that blood cells’ formation is not the function of the bone articulation. Hematopoiesis or blood cell formation occurs in the bone marrow. Marrow is the semisolid tissue that is found in the spongy bones. It is the main site where the development of new blood cells happens. Hence, option (b) is correct.

Explanation for the incorrect answers:

Option (a) is movement. Articulations are present between bone and cartilage. They are flexible and help in the movement of bones. So, it is an incorrect option.

Option (c) is stability. Stability is a property of resisting all kinds of dislocations that may occur at an articulation. The articulation at some joints does not allow movement and thus provides stability. So, it is an incorrect option.

Option (d) states providing growth in length for long bones. The epiphyseal plate found in the bones are temporary joints, which allow the growth of the long bones of the skeletal system. So, it is an incorrect option.

Hence, options (a), (c), and (d) are incorrect.

Conclusion

Therefore, it is concluded that the formation of blood cells does not happen at the bone articulation.
