Hassan’s Story – A&P Case Study

enquiry A Baru is using surface markings to identify the gender of a skull. What two major types of surface marking do atomic number 76s waste? closure Bone surface markings consist of a) Depressions and openings and b) Processes. Depressions and openings are areas that form joints or areas that allow passage of soft tissue, such as nerves, blood vessels, ligaments and tendons. Processes are projections or outgrowths on bone that form joints or attachment points for continuative tissue, such as ligaments and tendons.Question B Why are Liu and Hassan strike to find a metopic sutura on an bounteous skull? In which skull bone to metopic sutures occur? Answer Soon after birth the right and go forth sides of the frontal bone are united by the metopic suture. Normally the metopic suture disappears betwixt the ages of six and eight, so finding one on an cock-a-hoop skull would be surprising. Question C What delicate skeletal structures are assemble inside the nasal cavity that m ight be missing from and excavated skull?Answer Skeletal structures inside the nasal cavity that could be missing from an excavated skull would be septal cartilage, the vomer, the inferior nasal conchae and the perpendicular plate. Question D How would Hassan and his aggroup be able to tell the ages of the skeletal remains of the woman and the bollocks? Answer Age canful be estimated by examining the vertebral column. modal(a) length for an adult female is around 24 inches in an adult male it is approximately 28 inches. The total number of vertebrae can too help determine age. During early development there are 33 total vertebrae.This number decreases as people age be set the 5 sacral vertebrae as well as the 4 coccygeal vertebrae begin to merge together. Fusion of the sacral vertebrae begins between the ages of 16 and 18 and is usually absolute by age 30. The coccygeal vertebrae fuse when a person is between the age of 20 and 30. Question E What features of the vertebral col umn would the big skeleton in the sarcophagus show to indicate is was female? Answer In females, the tail bone points inferiorly to allow the passage of a baby during birth. In males, the coccyx points anteriorly.Question F What bone in the neck region otherwise than cervical vertebrae whitethorn be damaged during strangulation or neck trauma? Answer The hyoid bone. Question G If the bones of a person found at the excavation site were missed up and out of sequence, how could the anthropologists determine which vertebrae were cervical, lumbar or thoracic? Answer Vertebrae in the different regions of the vertebral column vary in size, shape and detail. Question H Why would bones, with their unwaveringly structure, be subject to and show signs of the malady that destroyed this community?Answer Bones are/were living tissue, albeit, hard on the outside. Visually, they would still show signs of lesions and tissue damage, plus DNA can be extracted and examined to determine the specif ic disease a person may have died from. Question I What structure passes through the transverse foramina of cervical vertebrae that would cause death if damaged as in the childs skeleton? Answer The dens, a peg-like process on the body of C2, could cause death if forcefully driven into the medulla oblongata of the brain.
