The human skeletal system
While bones are formed of a tough and rigid form of connective tissue which is highly mineralized with calcium deposits, the cartilages are not very tough and are do not possess a high degree of mineralization. …

The joints that connect a bone to another bone, a bone to a cartilage or a cartilage with another cartilage are important components of the skeletal system as they are responsible for the mobility of the human body (Skeletal system, n.d).
A new born infant usually possess around 230 bones while a fully grown adult will approximately have about 206 bones. The human skeleton is divided into two major components namely the axial and appendicular skeleton. The axial portion comprises about 80 bones which include those in the skull, vertebral column and thoracic cage which comprise the axis of the body. The appendicular portion has about 126 bones, attached to the axial skeleton, which include the different appendages within the body and includes the shoulder girdle, skeletal portions of the upper and lower limb and the pelvic girdle (Skeletal system, n.d; Kulkarni, n.d; Anatomy of the bone, n.d). The human body consists of 5 types of bones which are classified based on their shape and function. These include the long bones whose length is greater than their width such as the limb bones, the short bones with approximately equal length and width include the carpals and tarsals, the flat bones which are attached to muscles such as the breast bone mainly protect body organs, the bones of the vertebral and mandibles are irregular in shape and the sesamoid bones which are small and present in the joints such as the knee cap provide protection to the tendons (Kulkarni, n.d; Types of bone, n.d; Anatomy of the bone, n.d).

While driving through an intersection, another car went through the red light and struck the driver's training car. Based on your understanding of the functions of bone, consider the different potential injuries that can occur and list at least four functions and provide examples of how the body was able to respond to or address the physical trauma from the collision.

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).
The bones that make up the axial skeleton obviously differ from those that make up the appendicular skeleton. 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 nerves prompt body’s effectors (muscles that release a specific set of substance depending on the stimulus), to action.
The skeletal system supports movements and provides protection for its delicate internal organs. It cannot move without the help of
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
