Question 11

Function of bones

Answer 11

1.Provide support for the body
2.Protect delicate organs(ribcage protects)
3.serve as a site for growth

Question 12

Haversian canals

Answer 12

canals that blood vessels travel to reach each cell in the bone

Question 13

Is the specimen human or animal bone?

Answer 13

presence of plexiform bone means animal

Question 14

Biological Profile of Bone

Answer 14

Age of death
1.use of dentition(teeth)
2.Use of Long Bones

Question 15

Use of dentition(teeth)

Answer 15

-1st incisors-9 months of age
-1st permanent-molars, erupt about 6yrs old
-wisdom teeth-between 17-21 yrs old

Question 16

Use of long bones

Answer 16

-look at epipiphseal plate called metaphysics(growth area)
-still growing you see a plate gap
-after growing done, head and shaft fuse together you now do not see gap any more epiphyseal plate turns into a epiphseal line

Question 24

Chemical Finger Printing

Answer 24

1.Iodine Fuming-fatty acids of fingerprints residuals
2.silver nitrate-NaCI (AgNO3+NaCI) Reaction makes Ag+CI- AgCI(grayish finger print)
3.ninhydrin-amino acids of fingerprints residues-Ruhermann’s purple(100 C degrees)
4.Cyamoacrylate(super glue)-amino acids,protiens,fatty acids, of fingerprint residues(need moisture to speed up reaction) reaction a white precipitate
5.Fluorescence-Fluorescent dye(Rhodamine-6-G) to ayanacrylate
