Question

Which is NOT true regarding the epiphyseal plates?
A. They can be utilized to determine whether a bone is still growing longitudinally
B. It is a result of bone being converted into cartilage so the bone can grow
C. They are not visible on X-ray because of the cartilage they are composed of
D. Commonly found at the epiphyses of long bones

Which choice is NOT true regarding bone tissue?

A. Trabeculae are found within spongy bone
B. One of the organic materials of bone include calcium
C. Osteocytes reside within a little open space called lacuna within bone tissue
D. The periosteum is the outer protective covering of bone

Answer 1

Ans1:-B) It is a result of bone being converted into cartilage so the bone can grow.

Is wrong because

Concept:- Cartage is converted into bone so that bone can grow. Not reverse.

The growth plate, also known as the epiphyseal plate is a thin layer of cartilage that lies between the epiphyses and metaphyses, and is where the growth of long bones takes place.

Ans2:- B). One of the organic materials of bone include calcium

Is wrong because Ca is inorganic material of bone.

Bones consist of living cells embedded in a mineralized organic matrix. This matrix consists of organic components, mainly type I collagen – "organic" referring to materials produced as a result of the human body – and inorganic components, primarily hydroxyapatite and other salts of calcium and phosphate.
