A. Baru is using surface markings to identify the gender of a skull. What two major types of surface markings do bones have? The two major types of surface markings are depressions (or openings) and processes. Depressions and openings form joints or passageways for blood vessels and nerves. Processes form joints or points of attachment for ligaments or tendons. B. Why are Liu and Hassan surprised to find a metopic suture on an adult skull? In which skull bone do metopic sutures occur? Liu and Hassan are surprised to find metopic suture on an adult skull because the metopic suture occurs on an infant skull. Right after birth the left side and right side of the frontal bone are united by the metopic suture, and usually between the ages of six to eight years old this suture should have disappeared. The metopic suture occurs on the frontal bone. C. What delicate skeletal structures are found inside the nasal cavity that might be missing from an excavated skull? The skeletal structures that are found inside the nasal cavity that might be missing from an excavated skull are perpendicular Plate, middle & inferior nasal concha, and the vomer. D. How would Hassan and his team be able to tell the ages of the skeletal remains of the woman and baby? Hassan and his team would be able to tell the ages of the skeletal remains by the four main sutures, coronal suture, sagittal suture, lambdoid suture, and squamous sutures. E. What features of the vertebral column would the larger skeleton in the sarcophagus show to indicate it was female? The features of the vertebral column that would have the larger skeleton in the sarcophagus would show that it’s a female because a females vertebrae is smaller than a man’s. F. What bone in the neck region other than cervical vertebrae maybe damaged during strangulation or neck trauma? During strangulation or neck trauma, the...
