Consider the following statements:
$1$. Humerus is found in human leg.
$2$. Smallest bone of human body is Stapes.
Which of the statement(s) given is/are correct?

  1. Only $1$
  2. Only $2$
  3. $1$ and $2$

  4. None of these

Study the following statements:
$1$. Study of bones is called Osteology.
$2$. Process of bone formation is known as Ossification.
$3$. Sesamoid bones are formed by ossification in tendons.
Which of the statements given are correct about bones?

  2. $2$ and $3$
  3. $1$ and $3$
  4. $1$ and $2$

Match List I with List II and select the correct answers using the codes given the lists.

List I List II
A. Coating on the crown of a tooth $1$. Dentine
B. Mineralized material that forma bulk of a tooth $2$. Enamel
C. Top of a tooth $3$. Tooth root
D. Base of a tooth $4$. Tooth crown
  1. A-$1$, B-$3$, C-$4$, D-$2$
  2. A-$2$, B-$1$, C-$4$, D-$3$
  3. A-$3$, B-$4$, C-$2$, D-$1$
  4. A-$4$, B-$2$, C-$1$, D-$3$
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The crown coating is enamel (A-2), the bulk of the tooth is dentine (B-1), the top part is the crown (C-4), and the base is the root (D-3). Matching these gives A-2, B-1, C-4, D-3.

Bones of old persons are brittle and fractured more readily occur because they contain more _________.

  1. lacunae

  2. organic matter

  3. inorganic matter

  4. bone marrow
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Bone brittleness in the elderly is primarily due to a decrease in organic collagen content and an increase in the relative proportion of inorganic mineral salts, which makes the bones harder but less flexible.

Consider the following statements:
$1$. Bones and blood are mesodermal in origin.
$2$. Serum is plasma minus clotting factor.
$3$. Five types of leucocytes are found in mammals.
$4$. Bone forming cells are called Osteoblast.
Which of the statements given are correct?

  1. $1$ and $2$
  2. $2$ and $3$
  3. $1, 3$ and $4$
  4. $1, 2, 3$ and $4$
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Bones and blood are connective tissues (mesodermal origin), serum is plasma without clotting factors, there are five types of leucocytes (neutrophils, eosinophils, basophils, lymphocytes, monocytes), and osteoblasts form bone. All statements are correct.
