• Describe ossification in fetal development. During development, the fetal bones are made up of cartilaginous tissue, which is like osseous tissue, except it is more flexible. The absence of calcium salts in its intercellular spaces makes it less dense. As development continues, the process of the depositing of calcium salts into the cartilaginous tissue occurs, and continues throughout their life. Ossification is the gradual replacement of cartilage and its intercellular substance by bone…

Optokinetic and electromagnetic systems are widely used in laboratory settings to monitor three -dimensional (3-D) motion. These systems are accurate, but they have certain limitations like high cost, more space requirements and set–up issues. These limitations make them impractical for use at home[2].Miniature movement sensor modules[10] use accelerometers, rate gyroscopes and magnetometers to estimate 3-D orientation. These devices are more complicated and delicate to use at home by a…

There are multiple forms of flexibility testing that can be used created on the general outcome you are looking to achieve. These tests can range from Trunk and Lower Body (hamstring test, Straight Leg Raise, Modified Thomas Test, V-Sit test, Kraus Webber Floor Touch Test, Groin Flexibility test, calf muscle flexibility test, Trunk Rotation Test, Sit and reach, Back scratch test V sit-and-reach test) to upper body consisting of Shoulder Flexion (Shoulder Stretch, Back Scratch Test, Shoulder…

The biggest differences between the vertebrae in the spine, are shape and secondary functionality. The cervical vertebrae are the smallest, they are the most flexible allowing the biggest range of head movement. The only vertebra containing no vertebral body, the axis, is located in the cervical vertebrae. Thoracic vertebrae are mid sized, and the physical shape of the thoracic vertebrae are the most rigid because they connect the ribcage and torso to the spine. Thoracic vertebrae are the only…

Scoliosis is an ailment that affects the spine. The article “Assessment and Treatment of Scoliosis” focuses on three main questions. How should the GP assess a child with scoliosis? What is the natural history of adolescent idiopathic scoliosis? What is likely to happen to patients referred to orthopedic surgeons (Assessment, 2002)? After learning about the causes, history, and about referrals to orthopedic surgeons the article focuses on treatment options. The next step of the article is…

The spinal cord is ¾ of an inch wide and 42-45 centimeters in length. It extends inferiorly from the medulla oblongata to the inferior border of the L1 vertebrae. The spinal cord is divided into 5 parts that house the 31 pairs of spinal nerves. The cervical part is the superior part of the spinal cord. It contains neurons whose axons contribute to the 8 pairs of cervical spinal nerves. The thoracic part lies inferior to the cervical part. It houses the neurons for the 12 pairs of thoracic spinal…

The image I can’t get out of my head was how tired, unhealthy, and curved my back was. I was constantly having appointments with a doctor or specialist. I missed a lot of school and spent a lot of time in bed. My story really begins in February 2012 when I had spinal cord surgery at Children’s Hospital in Seattle. I was diagnosed with scoliosis when I was young but in February the curve of my spine was at 47 degrees, I was sent for an MRI that showed I had a tethered cord. My surgery was…

A herniated disk is a problem with one of the rubbery cushions or also known as a disk. A disk has a soft center and a hard covering. These are sometimes called a slipped disk or a ruptured disk. A herniated disk occurs with the inside of the disk pushes out through a tear into the hard part of the disk. It can affect the nervous around it. Which causes the pain, numbness or weakness in an arm or leg. In some cases some people do not have symptoms from a herniated disk. They also most likely do…

The claimant works as a truck driver. He had an injury on 08/28/2017 while he was tying down loads, he suddenly felt low back pain. He was unable to perform his work the following morning. MRI of the lumbar spine dated 09/13/2017 showed desiccation of disc at the L4-L5 level with circumferential disc bulge and mild degenerative change facets. There was a mild bilateral bony neural foraminal narrowing at the L4-L5 level with possible but not definite L4 nerve root impingement. The tip of the…

How you sleep may be harming your back Sleeping posture may affect the alignment of your spine. You should be aware of how each position could be affecting your spine alignment adversely. Sleeping on your side Sleeping on your side takes conscious positioning. The danger with sleeping on your side is that you could twist or strain the back if your hips, back, and shoulders are not in alignment. To align the body and prevent straining the back, you should put a pillow between your knees and put…
