The Human Skeletal System Assignment 1: Essay The human skeleton provides the internal framework of the human body and comprises of 270 bones at birth, decreasing to 206 bones by adulthood. The reason for this decrease, is that by adulthood, some bones that were once separate have become fused together. Most of the unfused bones in infants can be found in the skull, this is to allow for an easier transition through the pelvis in childbirth. Unfused bones can also be found in the arms and legs, to allow for growth into adolescence, when some of the unfused bones will become fused. Bones of the human body can be classified into two sections. The axial skeleton and the appendicular skeleton. The axial skeleton contains 80 bones and can be seen in the image (01). The bones comprise of: • 8 Cranial Bones • 14 Facial Bones • 1 Hyoid Bone • 6 Auditory Ossicles Bones • 26 Bones of the Vertebral Column • 25 Bones of the Thorax The appendicular skeleton is made up of 126 bones and can be seen in the image (01) The bones exist in the following regions: • 4 – Shoulder Girdle. • 60 – Arms/Upper Limbs • 2 – Hip Girdle • 60 – Legs/Lower Limbs. (01)(Weebly, 2017) The major bones of the human body can be seen in the image (02) and consist of the following: • Cranium • Mandible • Hyoid • Clavicle • Sternum • Ribs • Scapula • Humerus • Radius • Ulna • Tarsals • Metatarsals • Phalange • Carpals • Metacarpals • Vertebrae • Ilium •
The fibula (slender long bone that lies parallel with and on the lateral side of the
In this exercise, we will examine a fresh raw chicken bone to study bone structure.
Some examples include the following: clavicle, coccyx, femur, fibula, foramen magnum, mandible, maxilla, metatarsals, ossify, phalanges, radius, scapula, sternum, suture, tibia, ulna, and vertebra. All of these terms are associated with the skeletal system. The mandible, maxilla, and foramen magnum are located in the cervical vertebrae. The clavicle, scapula, and sternum are located in the thoracic vertebrae. The lumbar vertebra contains the humerus, ulna, and radius. The coccyx is located in the sacral vertebrae. The femur, fibula, metatarsals, phalanges, and tibia are located in the appendicular skeleton. The sutures are located in the skull. The vertebrae is the backbone of the body. Ossification is the formation of bone. These terms are important in knowing and learning the skeletal system.

The skeletal system includes ligaments, cartilage, and bones. Four major organs in the skeletal system are the
The top of the axial skeleton supports the cranium, a complex bony structure made up of eight
The skeleton is a very important part of the body and is separated into two sections: the appendicular and axial skeleton. The appendicular is any part of the body that attaches to another bone. Those include but not limited to the legs, arms, and hands. The axial bones are located within the center of the body like the spine and ribs. Bones in these two regions are classified into different shapes including long, short, irregular, and flat. Flat bones are found in the skull and ribs. The flat bones in the human body are flat and thin often curved. Short bones are the same size length wise and width wise. Those are found in the wrist and ankle. Irregular bone does not go into a category. This bone can be found in the pelvis. Lastly, is the
Case study of a radiographic examination of the appendicular skeleton for a patient attending the imaging department
The human skeleton can offer more information than meets the eye. In fact, when analysing an individual’s skeletal features it is possible to constitute a biological profile. In this essay, I aim to explore the multiple elements that a human skeleton could shed light upon such as age, sex, stature, diet, health and trauma.
The human skeleton can be divided into two main parts; the axial and appendicular skeleton.
There is all types of bones in your body, here are a few types. Long Bones, short bones,flat bones, irregular bones and sesamoid bones. That's a lot of types of bones.
The appendicular skeleton consists of 126 bones containing the appendage bones, the pectoral and pelvic girdles. It is responsible for the ability of movements and the protection of the major organs in the human body.
The musculoskeletal system is a made up of the muscular system and the skeletal system. The skeletal system provides the internal framework for the body, it protects the organs by enclosing it and anchors skeletal muscles so that the muscles can contract thus causing movement. The skeleton is divided into two divisions: the axial skeleton and the appendicular skeleton (Taylor & Cohen, 2013, p. 94). The Axial skeleton are the bones that have formed the longitudinal axis of the body which is made up of the skull, the vertebral column and the thoracic cage (Taylor & Cohen, 2013, p. 98). The Appendicular skeleton are the bones of limbs and griddles that are attached to the axial skeleton (Taylor & Cohen, 2013, p. 103).
Bone serves the organism at multiple levels: As a system, bones permit the organism to locomote effectively and to maintain posture by bearing loads without deformation, by providing rigid attachment sites for muscles and acting as a system of levers to amplify small movements. As an organ, bones protect the viscera and house the hemopoietic tissue (red marrow). As a tissue, bones serve as a reservoir of readily mobilizable calcium, an
Have you ever thought about how humans would be without bones? They would not be able to function the way that they do now if it did not have bones. The skeletal system is a highly important system in the human body, it functions as support, protection, and creation of red blood cells. This system is composed of bones and joints, an average adult contains 206 bone and an average child contains 270 bones because as a person grows the bones fuse together to create a single bone. The skeletal system is divided in to two major category: the axial skeleton and the appendicular skeleton. The axial skeleton has 80 bones in the midline axis which contains the bones of the head and the trunk; while the appendicular axis has 126 bones which include the bones from the limbs, pectoral and pelvic regions. There are only a few select bones that are mainly affected by the Paget disease these include the pelvis and the tibia which belong to the appendicular axis; however, other bones that could be affected are the femur, spine, skull, clavicle, and fibula.
