Question

Match List - I with List - II. List - I List - II
A. Catagen stage I. Middle layer of the hair
B. Anagen stage II. Transition stage in hair growth
C. Cortical fusi III. Small cells located in Cortex
D. Medulla IV. Rapid growth stage of hair
Choose the correct answer from the options given below :

• A. A-II, B-IV, C-III, D-I
• B. A-IV, B-II, C-I, D-III
• C. A-II, B-III, C-IV, D-I
• D. A-I, B-IV, C-III, D-II

Hint:

Hair growth: Anagen = growth, Catagen = transition; Medulla = center; Cortex = structure.

Answer 1

The Correct Option is A

Concept: Hair structure and growth phases are important in forensic examination. Hair consists of different layers and undergoes cyclic growth stages.

Step 1: Understanding Catagen stage (A).
Catagen is the transitional phase between active growth and resting stage. It is a short phase where growth slows down.
Thus, A $\rightarrow$ II.

Step 2: Understanding Anagen stage (B).
Anagen is the active growth phase where hair grows rapidly.
Thus, B $\rightarrow$ IV.

Step 3: Understanding Cortical fusi (C).
Cortical fusi are small, spindle-shaped air spaces found in the cortex of hair.
Thus, C $\rightarrow$ III.

Step 4: Understanding Medulla (D).
The medulla is the central or middle layer of the hair shaft.
Thus, D $\rightarrow$ I.

Step 5: Forming correct combination.
\[ A-II,\quad B-IV,\quad C-III,\quad D-I \] Final Conclusion:
Hence, the correct answer is option (1).
