The Correct Option is A

Solution and Explanation


Step 1: Understanding the Concept:

Histological classification of major salivary glands: serous (parotid), mucous, and mixed seromucous glands (mandibular/submaxillary and sublingual).

Step 2: Detailed Explanation:

Histological classification of salivary glands in domestic animals:
1. Mixed (Seromucous) Salivary Glands: Contain both serous acini (watery enzyme secretion) and mucous acini (viscous mucin secretion) with serous demilunes (Gianuzzi). Examples include the A. Submaxillary (Mandibular) Glands and B. Sublingual Glands (polystomatic/monostomatic).
2. Pure Serous Glands: Parotid salivary gland.
3. Predominantly Mucous Glands: Palatine, buccal, and labial minor salivary glands.
Therefore, the classic major mixed glands are A and B only.

Step 3: Final Answer:

Hence, salivary mixed glands include A and B only, corresponding to option (A).
