MODEL DESCRIPTION: This model of the skull contains 1,133,096 4-noded tetrahedral elements and 247,854 nodes. Loads, constraints and material properties are included. Loads simulate forces imposed by the paired temporalis, masseter, and medial pterygoid muscles. Uniform traction is applied to the surfaces of elements that represent muscle attachment areas. The direction of traction varies from element to element such that it is always directed toward a node that represents the area of muscle insertion.

PROJECT: This model of a Jamaican Fruit Bat (Artibeus jamaicensis) was used to evaluate different methods of applying muscle loads to bone. This model contains more anatomical detail than the Artibeus jamaicensis model presented in Dumont et al., 2005.

ORGANISM: A. jamaicensis is species of leaf-nosed bat (Family Phyllostomidae, Order Chiroptera) that is common throughout the neotropics.
