Human Skeletal System
Question 1
Skeletal System
The skeletal system is a strong yet light, flexible living framework that supports the body, protects delicate internal organs and makes movement possible. In addition, our bones store minerals while red bone marrow produces blood cells.
Support
The skeleton provides a frame that shapes the body and holds it up. Within the skeleton different characteristics of support can be identified. As the body’s main axis, the backbone provides support to the trunk with its upper most section. Attaching to the top of the backbone, the neck bears the weight of the head. The backbone also provides attachment points for the ribcage, which supports the wall of the thorax, or chest. The backbone furthermore positions the head and trunk above, and transfers their weight through the pelvis to the legs. The pillars that support our weight when we stand. The pelvis itself support the organs of the lower abdomen such as the bladder and intestines Roberts, A.R, 2010.
Movement
The human skeleton is a smooth, flexible structure. Where bones meet, they form joints, with the majority being flexible and allow movement. The variety of movements available to each joint depends on and a range of factors, some of which are the conformation of the joint and how tightly ligaments and skeletal muscles are attached holding it together. Each bone has specific points to which muscles are joined by tendons. Muscles contract to pull bones in order to create an array of movements as diverse as running, grasping objects and breathing Roberts, A.R, 2010.
Protection
The skeleton provides protection to our bodily organs such as the brain, heart and lungs. If it weren’t for the bones (particularly the brain and ribcage) organs could easily be damaged. The skull is built from interlocking bones, eight of which form the helmet-like cranium, a strong, self-bracing structure that surrounds the brain. The bones of the cranium also house the inner parts of ears and, together with
