Bone Markings Essay
Analyze the bone markings of the vertebrae and distinguish among the cervical, thoracic, and lumbar vertebrae.
Vertebrae possess a vertebral body, which is anterior in position which are the major weight bearing components of the bone. Attached to the posterior of the body is a posteriorly projecting piece of bone known as a pedicle. There is a pedicle on the left and right hand sides. The pedicle is continuous with the lamina. The lamina from the left and right sides join in the midline and form a bony protuberance known as the spinous process. At the point where the pedicles meet the laminae, there is a laterally projecting piece of bone known as the transverse process. There are two upward and two downward projecting protuberances of bone, …show more content…
Gliding: Flat or slightly flat surfaces move against each other allowing sliding or twisting without any circular movement. This happens in the carpals in the wrist and the tarsals in the ankle.
Categorize three different joints found within the vertebrae, including the bone markings of each bone and the movements produced by those joints.
A joint is a meeting, or juncture, between two or more bones within the skeletal system. They are classified as synarthrotic, amphiarthrotic, or diarthrotic, based upon how much mobility they provide to that particular part of the body.
A synarthrotic joint provides little or no movement, whatsoever. The suture lines in the skull would be a perfect example of a synarthrotic joint. When an infant is born, the skull is largeley cartilaginous, to facilitate the infants passing through the birth canal. The cartilage later turns to bones, the suture lines represent where the skull pieces came together.
An amphiarthrotic joint is a joint that provides limited movement to that particular part of the body. A good example of that would be the joints in the backbone, between the individual vertebras of the
