Concept:
Understanding the body structure of cattle is essential in animal husbandry. The external anatomy of cattle is arranged from anterior (front/head region) to posterior (rear/tail region). Each body part has a specific position along the body axis.
Step 1: Understanding "Poll"
• Poll is the topmost part of the head.
• It lies between or just behind the horns.
• It is the most anterior (front-most) part among the given options.
Thus, Poll (A) comes first.
Step 2: Understanding "Hump"
• Hump is located just behind the neck.
• It is prominent in Indian cattle breeds.
• It comes immediately after the head region.
Thus, Hump (B) comes second.
Step 3: Understanding "Back"
• Back is the central portion of the body.
• It lies behind the hump and extends towards the loin.
Thus, Back (C) comes third.
Step 4: Understanding "Loin"
• Loin is located behind the back.
• It is the region between ribs and hip.
Thus, Loin (D) comes fourth.
Step 5: Understanding "Croup"
• Croup is the rear-most part near the tail.
• It is part of the hindquarters.
Thus, Croup (E) comes last.
Final Order:
\[
A > B > C > D > E
\]
\[
\boxed{A, B, C, D, E}
\]
