$1$. Tendons connect bone to muscles.
$2$. Bone forming cells are osteoblasts.
$3$. Ligament connect bone to bone.
Which of the statements given are correct?

  1. $1$ and $2$
  2. $2$ and $3$
  3. $1, 2$ and $3$

  4. None of these

C Correct answer
Explanation

Tendons connect muscles to bones, ligaments connect bones to bones, and osteoblasts are indeed the cells responsible for bone formation. All three statements are biologically accurate.

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.

Which one of the following carries out the function in human being similar to the one which Malpighian tubules perform in cookroach and other insects ?

  1. Lung

  2. Kidneys

  3. Heart

  4. Reproductive organs
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Malpighian tubules are the primary excretory organs in insects, serving a function analogous to the kidneys in humans, which filter waste from the blood.

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

  1. Production of eythrocytes

  2. Storage of minerals

  3. Production of body heat

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

  • The adult human skeletal system consists of 206 bones, as well as a network of tendons, ligaments and cartilage that connects them.
  •  The skeleton serves six major functions: support, movement, protection, production of blood cells, storage of minerals and endocrine regulation. Hence, Production of body heat is not a function of the skeletal system.
 So, the correct answer is 'Production of body heat

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The water and electrolyte content of skeletal muscle was an average of 78.8 gm. of water, 4.96 milliequivalent (meq.) of sodium, 8.32 meq. of potassium, 4.04 meq. of chloride, 0.445 meq. of magnesium, and 3.88 meq. of phosphorus per 100 gm. of wet tissue or muscle. Hence, the percentage of water content in skeletal muscle can vary from 75-78%.

Which one of the following is the correct description of a certain part of a normal human skeleton?

  1. Parietal bone and the temporal bone and the skull are joined by fibrous joint.

  2. First vertebrae is axis, which articulates with the occipital condyles.

  3. The 9th and 10th pairs of ribs are called the floating ribs.

  4. Glenoid cavity is a depression to which the thigh bone articulates.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A suture is a type of fibrous joint, which only occurs in the skull. These joints are synarthroses. One parietal bone is located on each side of the skull just behind the frontal bone. The temporal bones are situated at the sides and base of the skull, and lateral to the temporal lobes of the cerebrum.
