Oral cavity: It is the beginning of the digestive tract, with functions such as feeding, moistening, chewing, swallowing, and taste, the anterior boundary of the oral cavity is the lab, the sides are buccal, and the top is the hard palate and the soft palate extending backwards.
The bottom is the muscle, and the back communicates with the pharynx. There are tongue, teeth, and salivary glands in the mouth.
of the opening. The rabbit's upper lip has a longitudinal fissure in the midline, forming a mouth (rabbit lip), so that the incisors are exposed. The soft palate of rabbits is very long, the tongue is short and thick, the tongue muscles are very developed, with well-developed incisors, no canine teeth, and the molars have a wide chewing surface and a transverse crest, which is suitable for grinding forage.
There is a wide tooth gap between the incisors and molars. The rabbit teeth are also unique in that the upper jaw has two pairs of incisors (one pair of front teeth and one pair of small front teeth) that form a special double incisor tooth shape. There are 28 adult rabbits in total, and their tooth patterns are:
2 0 3 32 ( )=281 0 2 3 Incisors Canines Premolars Posterior molars The total number of deciduous teeth in young rabbits is 16, and its tooth pattern is: 2 0 32 ( )=161 0 2 incisors Canines The saliva of the premolars can only moisten food, and also contain starch that can be converted into glucose.
(the strength of rabbit saliva to break down starch is weak). There are 4 pairs of salivary glands in rabbits, namely the parotid gland and the submandibular gland.
Sublingual glands (this is characteristic of rabbits, mammals.
Infraorbital glands are generally absent). They all secrete saliva, which is passed through a catheter into the mouth. In this way, the rabbit has already started mechanical and chemical digestion in the mouth.

Rabbits are not rodents, and rabbits are taxonomically rabbit-like rather than rodents. Rodents are an order of mammals characterized by two incisors in the upper and lower jaws that continue to grow, and rodents must gnaw to continuously shorten these two pairs of front teeth. Rabbits, like rodents, have large, rootless incisors that grow throughout their lives, so rabbits, like other rodents, need to grind their teeth by biting and grinding to ensure that their lips close properly.
Rabbit is the general name of all genera of the mammalian order Lagomorphidae. Commonly known as rabbits. Biological classification: Zootopae, phylum Chordates, subphylum Vertebrates, Mammals, Cerniformes.
Rabbits have long tubular ears (ears are several times longer than the width of the ears), a short tail in tufts, and strong hind legs that are much longer than the forelimbs. There are 43 species in 9 genera. The largest number of species are found in eastern Asia, southern Asia, Africa and North America, and a few species are found in Europe and South America, some of which are widely distributed or introduced into many regions, while many species are very limited.

<> Bunny Blouse Do you know why rabbits keep eating potatoes and grinding their teeth? Because a rabbit has the same characteristic as a mouse, that is, his teeth will always grow, so the rabbit, like a mouse, needs to grind his teeth constantly to ensure that the lips can be closed normally.
then Are rabbits rodents? To be precise, like mice, rabbit teeth do grow continuously, and it is for this reason that they were once classified as rodents by early naturalists, but rabbits belong to the order of rabbits, which is a special branch, and the main difference with rodents is that behind the two front teeth of rabbits, there is a pair of teeth, which rodents do not have.
Owners should beware, too long front teeth can prevent rabbits from closing their lips, prevent them from eating properly, and in the worst cases, even starve to death. And if the roots of the front teeth grow inward, the long roots may block the rabbit's tear ducts, which will lead to tear and bacterial infection. Therefore, owners should remember to give the rabbit a lot of hay to grind its teeth.
