Key Anatomical Facts about Mammary Glands (Udder)
- Ectodermal in origin (derived from the ectoderm layer of the embryo).
- Innervated only by sympathetic fibres; parasympathetic fibres are absent in the udder.
- No communication exists among all 4 quarters of the udder — this minimizes the spread of infection within the udder.
Suspensory Structures of the Udder
- Median suspensory ligament (elastic) — primarily responsible for udder breakdown.
- Two lateral suspensory ligaments (non-elastic).
- Skin.
Blood Supply
- Arterial: External pudic artery (mammary artery)
- 400–500 ml of blood must pass through udder to produce 1 ml of milk.
- Subcutaneous abdominal vein (milk vein) acts as index for milking ability.
