In rabbits, the number of salivary glands present are

The correct option is 4 pairs.

In rabbits (Oryctolagus cuniculus), the digestive system is adapted to process a herbivorous diet, beginning with the mechanical digestion in the oral cavity. To facilitate this process, rabbits possess four pairs of salivary glands that secrete saliva to lubricate food and initiate enzymatic breakdown. These four pairs of glands are:
1. Parotid glands: Located near the base of the ears, one on each side.
2. Submandibular (or Submaxillary) glands: Situated in the angle of the lower jaw.
3. Sublingual glands: Found beneath the tongue.
4. Infraorbital glands: Positioned below the eye orbit, a characteristic feature in rabbits.
Together, these four pairs make a total of eight salivary glands discharging saliva into the buccal cavity.
