Q Question 1 0.25 / 0.25 pts Use this image of a chimpanzee skull seen in a superior view to identify the cranial length and width. Correct! Question 2 0.25 / 0.25 pts If you measure a different chimpanzee skull and find the following: Cranial width = 82 mm Cranial length = 125 mm These are not the same measurements as seen in the skull in Question 1. What is the cranial index? Remember Cranial Index = width / length x 100 Question 3 0.25 / 0.25 pts You measure the basion to opisthocranion and the basion to prosthion for both the chimp and human skulls shown below. Inferior views of skulls Chimp Human Basion to Opisthocranion = 70 mm Basion to Prosthion = 135 mm Basion to Opisthocranion = 92 mm Basion to Prosthion = 94 mm Photo Credit: Angela Rockett Kirwin. 2020 LACCD Using the equation for the condylar index, calculate the index for both skulls. Condylar index = Ba to Op / Ba to Pr x 100
