anelodont - premolars and molars
elodont - incisors
bradyodont - premolars and molars
Define anelodont regarding gerbils, hamsters, mice, and rats - which teeth, etc
premolars and molars
rooted, but not growing throughout life
Define elodont regarding gerbils, hamsters, mice, and rats - which teeth, etc

close to parturition event
pubic symphysis ligaments open prior to delivery of large feti
What must NOT happen before a sow gives birth. When?
pubic symphysis will fuse if one does not have a litter prior
6-9 months
If a sow has a litter BEFORE fusion of pubic symphysis, what happens?
cartilage union forms and persists for life
