Answer 1

Question no 1

No because A sagittal crest is a ridge of bone running lengthwise along the midline of the top of the skull (at the sagittal suture) of many mammalian and reptilian skulls, among others. The presence of this ridge of bone indicates that there are exceptionally strong jaw muscles.

Question no 2

Yes because Prognathism happens when your lower jaw, upper jaw, or both halves of your jaw protrude beyond the normal range. It can be caused by a genetic or inherited condition or an underlying medical condition. It can also develop for unknown reasons.

Question no 3

Yes because The brow ridge, or supraorbital ridge known as superciliary arch in medicine, refers to a bony ridge located above the eye sockets of all primates. In Homo sapiens sapiens (modern humans) the eyebrows are located on their lower margin.

Question no 4

Yes becauy in physical anthropology, post-orbital constriction is the narrowing of the cranium (skull) just behind the eye sockets (the orbits, hence the name) found in most non-human primates and early hominins.

Question no 5

Yes placement of eye is forward or to sides

Question no 6

Yes the dental formula is correct

Question no 7

Yes it is true as it is the projection beyond normal levels

Question no 8
