Conclusion 1 How did your findings compare to the rest of your team and to the 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

Project 1.2.3: Bone Detectives Introduction When we think of bones‚ we most often think of the way in which these hard structures support the body‚ how they work with muscles to produce movement and how they protect our internal organs. But the 206 bones of the human skeleton can also tell a story. The specific structure of your bones reveals information about your gender‚ your height‚ your age and even your ethnicity. These biological clues are often the first pieces of evidence scientists

Chapter 6 Study Guide 1. List and describe the major functions of the skeletal system. Elaborate. Support: the framework that supports the body and cradles the organs. Protection: surrounds the brain‚ spinal cord‚ and vital organs. Movement: bones are levers for muscles. Minerals: bones store calcium and phosphate. 2. Compare the axial skeleton with the appendicular skeleton. Axial: forms the long axis of the body and include the bones of the skull‚ vertebral column and the rib cage

Chapter 5: The Skeletal System I. Introduction. The skeletal system consists of the bones‚ along with the cartilage and fibrous connective tissue that make up the ligaments that connect bones to bone at joints. A. Functions of the Skeleton. 1. The skeleton supports the body. 2. The skeleton protect soft body parts. The skull protects the brain‚ the rib cage protects the heart and lungs‚ and the vertebrae protect the spinal cord. 3. The skeleton produces blood cells. Red bone marrow contains

There are six steps in this type of ossification and they are as follows; one the development of cartilage model‚ two the growth of the cartilage model‚ three the development of the primary ossification center‚ four the development of the medullary cavity‚ five the development of the secondary ossification centers‚ and six the

Here it is easily available and turns over fast. In pregnancy the demands of the fetus for calcium require a suitable diet and after menopause hormonal control of calcium levels may be impaired: calcium leaches out leaving brittle osteoporotic bones. 4.

Long Answer Question 2 3) Calcium in the diet of a teenager is actively absorbed in the small intestine and transferred into the intestinal capillaries. Describe the route this calcium would follow to end up in the upper arm. Describe in detail the role of calcium at the neuromuscular junction as well as its role in the mechanism of muscle contraction and relaxation of the triceps. Considering the function of calcium in bone growth‚ explain in detail how the humerus would grow in length. Calcium
