ANS lab notes 1

cutting (ex. apple and carrot)

holding and /or tearing( ex. meat, connective tissue

bicuspids ( course grinding - mastication )

tricupids (fine grinding - mastication)

canine based teeth for tearing, limited mastication- large esophagus

classic carnivores like cat and bobcat

small incisors , large canines and have premolars and molars

sometimes considered not a true carnivore ( carnivore/omnivore )

chameleons and armadillos both insectivores

large grinding surface area of premolars / molars lack of canines except horses no upper incisors (cow , sheep, goat) musical is designed for rotational motion which increases mastication

grazing animals predominantly grasses, high fiber plants

upper and lower incisors canines are 10-20% in both male and female , premolars and molars are large and flat.

a grazing animal predominantly grasses and high fiber

no upper incisors or canines tend to have sharper premolars/molars

sheep are grazing animals and deer and goats are browsing animals which means they are selective they prefer fruits /seed/forbes and plants with lower fiber than grasses

no upper incisors or canines (few deer have canines) have sharper molars and premolars ( grinding for plants and seeds)

seed eaters and have sharp incisors to break seed coats

sharp defined incisors usually single pair no canines high grinding surface area ex. mouse, squirrel , muskrat, beaver

characteristics of both herbivores and carnivores large insidsores, presence of canine, premolars some are sharp and some are flat, molars grinding surface area

classical omnivores similar to human teeth structure

not true carnivores more carnivores and omnivores

raccoon, opossum, river otter
