Extract of sample "Skeleton"

Skeleton The pelvis is able to help in determining the gender in forensic science. This can be determined byischiopubic index where males have an IP index of 75-85 while the female ranges between 90 and100. However, the success of this method is higher when the male or female is at the age of adolescence or adulthood (Ortner, pp. 40).
Body
In determining the gender of the bones submitted to the UCO Biology Department, it is crucial to look at the Ischiopubic Index and the subpubic angle.
Ischiopubic Index
Ischiopubic Index= ((length of AC in cm) * 100) / ((length of AB in cm)
AC is the distance of A to the pubic tubercle
AB is the distance from A to the ischial tuberosity
AB= 2cm
AC= 1.5 cm
(1.5*100)/ 2= 75
Subpubic angle
From the diagram provided, the subpubic angle of the bone is 30 degrees, which is lower than the range expected from the female gender, which ranges between 80 and 90 degrees as compared to that of males that ranges from 50 to 60 degrees. This further supports the results above indicating that this is a male gender.
Conclusion
From a general observation of the bones provided, the pelvis is narrow. The birth canal is also narrow as expected from a male gender. The Ischiopubic Index gives an IP index of 75 which indicates that the bones belong to a male gender. The ischiopubic index of males has an IP index of 75-85.

The movement follows the pattern of a lever of the third order, wherein the load is located at the hand, and the fulcrum at the elbow (Peterson & Bronzino, 2008). 2) In no more than 250 words describe the function of the skeleton and its importance in movement. The human skeleton is an integrated framework of 206 bones which supports the soft tissue and protects the vital organs (McKinley & O’Loughlin, 2008). The skeletal system has been classified as the axial skeleton, comprising of the bones lying along the central axis of the body, which includes the skull, the vertebral column and the rib cage; and the appendicular skeleton,...

Structure of the Bone

...? Structure of the Bone Structure of the Bone The human body comprises of many different systems which work together for its proper functioning. The skeletal system is one of the most important systems of the body. The skeletal system of the human body comprises of 206 bones. Skeletal muscles are attached to these bones which assist in their movement. These muscles are in turn regulated by the impulses from the central nervous system. The skeletal system also has many structural as well as physiological roles that it performs (Alcamo and Krumhardt 2004; Plowman and Smith 2007). Anatomically, the human skeleton is classified into two parts. These include the axial skeleton and the appendicular...

The axial skeleton is made up of skull, the hyoid bone, the auditory ossicles, the vertebral column, and the thorax, which is made up of the ribs and the sternum, or breastbone. The axial skeleton is made up of 80 bones and comprises roughly 40% of the total number of bones in the human body. Basically, the axial skeleton functions as a protective case for the internal organs of the central nervous system, which is protected by the...

The Skeletal System

...There are 206 bones in the human body and all of those combined to give the framework and structure is known as the skeletal system.The skeletal system performs many vital functions, foremost of which is providing the structure for organs and tissues to attach. The system performs five main functions. The ordered arrangement of the bones make up the shape of the human body and determines the physical characteristics of a person. Moreover the skeleton also provides support to the internal organs like brain, spinal nerves and heart. This support not only involves keeping these organs in place but also protecting them from injury. Finally, bones contain bone marrow from the red blood cells develop and are also storing...

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 the first skeleton to be discovered as a majority of the past discoveries were minor bone fragments. The skeleton was discovered in Hadar, Awash Valley in Ethiopia. This discovery was made in the year 1974 by Donald Johanson (Tomkins, n.p). Paleontologists have dated this skeleton to be approximately 3 million years old and have placed it...
