Question

which of the following is not a function of the skeletal system?

• protection of internal organs
• communication
• blood cell formation
• mineral storage

question 46

in adults, most bone marrow in the body is yellow.

• true
• false

Explanation:

Analyze skeletal system functions

Using the Skeletal Anatomy knowledge point

• The skeletal system provides physical protection for delicate internal organs (e.g., cranium protecting the brain, rib cage protecting the heart and lungs).
• It is the site of hematopoiesis, which is blood cell formation occurring in red bone marrow.
• It acts as a reservoir for minerals, storing and releasing calcium and phosphate.
• Communication is a function of the nervous and endocrine systems, not the skeletal system.

Evaluate bone marrow distribution in adults

Using the Yellow Bone Marrow Function knowledge point

• In infants, red bone marrow is present in almost all bone cavities to support rapid growth.
• During transition to adulthood, much of this red marrow is replaced by yellow bone marrow (fatty tissue).
• Consequently, in adults, the majority of bone marrow throughout the skeleton is yellow marrow, primarily located in the medullary cavities of long bones.

Answer:

Question 1

• protection of internal organs
• communication (Correct answer)
• blood cell formation
• mineral storage

Question 2

• True (Correct answer)
• False
