Paleontologists discovered 40% of the bones which make up the skeleton of the genus Australopithecus afarensis ("Mother of man - 3.2 million years ago", n.p). This was…

Introduction

The archeological findings of this skeleton showed a skull which is smaller than that of humans (Tomkins, n.p). The skeleton showed evidence of the bipedal upright posture.
The skeleton was 3ft 7in tall and weighed approximately 64 pounds. The skeleton had a similar appearance to that of a chimpanzee (Tomkins, n.p). The skeleton had a smaller skull, hence, a smaller brain than that of humans. However, the structure of the pelvic and leg bones was identical to that of Homo sapiens sapiens, which suggested that they performed similar functions to those of modern man and walked in an upright position (Institute of Human Origins, n.d).The archeological findings were re constructed in the University of Cleveland by Owen Lovejoy (Institute of Human Origins, n.d). Another factor which showed that Lucy walked upright was her valgus knee; her greater trochanter was short and similar to that of humans (Institute of Human Origins, n.d). Her feet were also discovered to be physiologically flat. The reconstruction of her sacrum showed it had a broad iliac flare, and broad inner acetabular distance and a long superior pubic ramus (Institute of Human Origins, n.d). Her pubic arch was similar to that of humans. She had a smaller cranium and spatulate canines. Her cranial capacity as mentioned above was smaller than that of humans. Her mandible showed similarities to that of gorillas (Institute of Human Origins, ...

Structure of the Bone
Anatomically, the human skeleton is classified into two parts. These include the axial skeleton and the appendicular skeleton. The central structural framework of the bones of the human body is known as the axial skeleton. This consists of eighty bones. The bones of the axial skeleton include the facial bones, bones of the cranium, hyoid bone, auditory ossicles, sternum, ribs, vertebrae, sacrum…
Human appendix
The seemingly innocuous lumen which can barely admit a match stick leads to the presupposition that it has no function, which was originally supported by its small arterial supply. The microscopic picture of the appendix in the luminal aspect, however, is marked by presence of inner lining of colonic-type mucosa that covers the lymphoid tissue located within its wall which is supplied by small…
