Which one of the following pairs of structures is correctly matched with their correct description?

  1. Structure Tibia and fibula, Description Both form parts of knee joint
  2. Structure Shoulder joint and elbow joint, Description Ball and socket type of joint
  3. Structure Cartilage and cornea, Description No blood supply but do require oxygen for respiratory need
  4. Structure Premolars and molars, Description 20 in all and 3-rooted

Answer

(3) Structure Cartilage and cornea, Description No blood supply but do require oxygen for respiratory need

Solution

(1) The knee joint is formed by femur, tibia and patella; fibula does not take part in it. ⇒ Incorrect.

(2) As per NCERT, the shoulder joint is a ball and socket joint, but the elbow (between humerus and ulna) is a hinge joint. ⇒ Incorrect.

(3) Cartilage and cornea are avascular (no blood supply), yet their living cells respire; they get oxygen by diffusion (cornea from air / aqueous humour, cartilage from the surrounding tissue fluid). ⇒ Correct.

(4) As per NCERT, the dental formula of adult human is 21232123, i.e., 8 premolars and 12 molars = 20 teeth, but premolars have one or two roots, not three. ⇒ Incorrect.

Answer: (3)
