The sacral plexus lies in the back of the pelvis‚ between the piriformis muscle and the pelvis fascia and nerves coming from this plexus converge toward the lower part of the greater sciatic foramen and unite to form a flattened band‚ which continues primarily as the sciatic

The base is much enlarged in the antro-posterior direction stabilizing the body for exercises in a sagittal plane. Rotation of the pelvis towards the side of the forward leg is prevented by the position of the back leg. * Uses: 1- Localize rotation of the spine. 2- Tension on the hamstrings of the forward leg prevents forward tilting of the pelvis in trunk flexion exercises. 4- Half standing The whole weight of the body is supported on one leg‚ the other may be free or supported

actual data provided by your teacher? What could account for any variation? 2 Why do you think the pelvis is often the first bone forensic anthropologists look to in determining sex from skeletal remains? The pelvis is the first bone anthropologist look at because a male can not fit a human head through their pelvis. A female (the one that is pregnant) can fit a babies head through her pelvis because its wide enough and doesnt have anything blocking where the baby comes out at. 3 The developmental

Topic 1 In anatomy and physiology‚ one of the things you will learn about is bones. Bones do so much for a person and they can even do things for you after death. This semester we discussed bones. We labeled the human skeleton and that allowed us to be able to see where each bone is and what is does for the body. We learned things such as the functions of bones which is that they support and protect soft tissues‚ store inorganic salts‚ form passageways‚ provide points of attachment for muscles‚ and

Finding of Lucy Lucy was a 3.2 million old Australopithecus Afarensis skeleton to ever be found. She was found in Ethiopia on November 24 1974. They first spotted the forearm bone and then they found some other parts of her body as well. Only 40% of her bones have been found yet. Lucy’s discovery is very important to the world because it shows everybody how their ancestors might have looked in the past. It is also important because it helps us understand our past and where we came from

The bones of the adult skeleton are classified by size and shape (long‚ short‚ flat‚ or irregular). The skull rest at the top of the spinal column and houses

billion years ago. In 1974‚ Donald Johanson discovered something in northeastern Ethiopia that seemed to be the skeleton of an ape. The skeleton was 40 % complete. It consisted of skull fragments‚ a lower jaw‚ ribs‚ an arm bone‚ a portion of a pelvis‚ a thighbone‚ and fragments of shinbones. It was thought to be a female adult about 3.5 million years. Dr. Johanson believed that this ape was very human-like and said that she started evolving into a human. Close to the skeleton‚ they found footprints

Introduction I have always wanted to travel the world and discover many new artifacts and fossils that have not been found before. I found myself very interested and passionate about evolution and how our ancestors evolved into modern human. That is when I decided to pursue a career in paleoanthropology because I knew that was a career with many opportunities to travel the world and possibly discover fossils. In college‚ I have had a lot of hands on field experience in paleontology and it was a place
