Capsular process

Bony capsules located in rodents From Wikipedia, the free encyclopedia

In rodents, the capsular process or projection is a bony capsule that contains the root of the lower incisor. It is visible on the labial (outer) side of the mandible (lower jaw) as a raising in the bone.[2] There is marked variation within species in the development of this process.[3]

The marsh rice rat (Oryzomys palustris) has a reduced capsular process.[1]

Most oryzomyines have a well-developed capsular process, which is usually located behind the coronoid process, but many have a small one, and some lack the structure entirely.[4] Phyllotines and akodontines are also variable in their development of a capsular process.[5]
