Step 1: Basic structure.
The cow udder is divided into four quarters, each with one teat. The front and rear quarters are separated by ligaments. Step 2: Internal parts.
- Alveoli: Small milk-secreting units.
- Gland cistern: Collects milk from alveoli.
- Teat cistern: Stores milk before release.
- Teat canal: Passage for milk flow. Step 3: Diagram representation.
In an exam, a neat labelled diagram is required showing four teats, udder quarters, alveoli, gland cistern, and teat canal.
