The key function of the cervical spine is to support the weight of the head which is approximately 10-12 pounds. The spinal cord is the key path for information between the brain and the peripheral nervous system. It transmits signals back and forth between the body and brain. The length of the spinal cord is about 45 cm in men and 43 cm in women. Within this spinal link, there are thirty one pairs of spinal. Each spinal nerve splits into two roots before connecting to the spinal cord.
The human body is a weight-bearing exterior and an addition for the disc. The vertebral arch systems the spinal canal through which the spinal cord runs. The developments arise from the vertebral arch to form the facet joints and processes for muscle and ligament attachments.
The spinal column is made up of bones called vertebrae which are to a certain degree flexible while some of the vertebrae in the lower parts of the spinal column are fused. The spinal cord is enclosed by the spinal column which consists of 33 vertebrae
Cervical – Upper seven vertebrae located in the neck (C1-C7)
Thoracic – Twelve vertebrae that extend through the chest area (T1 – T12)
Lumbar – Five vertebrae in the lower back (L1 – L5)
Sacral – Five vertebrae located in the pelvic area (S1 –S5)
Coccygeal – Four fused vertebrae (tailbone)
The cervical spine has the highest range of motion because of two particular vertebras that move with the skull while cervical vertebrae are the smallest. The first cervical vertebra is called the atlas and is dissimilar from the further vertebrae. It is ring-like in shape with two large lumps on the sides to sustain the weight of the head. The second cervical vertebra is called the axis. The axis is a bony peg-like bulge, call...

The musculoskeletal system offers support and stability for your body so we can properly function and move around. Different types of muscle within the muscular system include cardiac, skeletal, and smooth. The reason our bodies are capable of producing movement is because of the way our muscles contract. Our adult skeletal structure is made up of 206 bones that all differ in shapes and sizes. The composing parts that make up the system include the bones, joints, and muscles that all connect so we’re capable of moving. These components allow for our bodies to maintain a stable structure that can keep us upright. The axial skeleton refers to the skull, the vertebral column which supports the spinal cord, ribs, and sternum. It offers protections

This portion of the skeletal provides the main structural support for the body while also protecting the central nervous system and vital organs in the thorax (heart, lungs, etc.). Of primary importance is the adult vertebral column, consisting of 33 vertebrae divided into five groups and named according to the region of the body in which they are located. The upper seven are cervical vertebrae, followed in descending order by 12 thoracic vertebrae, five lumbar vertebrae, five sacral vertebrae fused into one bone as the sacrum, and four coccygeal vertebrae fused together into one bone called the coccyx. The sacral vertebrae and coccygeal vertebrae become fused in the adult, so there are only 24 movable vertebrae (Fig given
The car accident could damage ones spinal cord if it was crushed or hit hard enough. If the spinal cord is severed, the peripheral nerves may detach from the spinal cord. Detachment may lead to pressure applied by other organs or bones. The wreck may cause broken bones that would compress the spi...

The skeletal system frames our entire bodies and protects our fragile inner organs. We have two major types of bone in our body: compact bone and spongy bone. Compact bone is dense and looks smooth, while spongy bone is comprised of small needle-like pieces of bone with lots of open spaces. Our body contains 206 bones. The skeleton is separated into axial and appendicular sections. The axial skeleton includes the bones in the longitudinal axis of our body. The appendicular skeleton consists of the limbs and girdles of the body, such as our arms and shoulders. There are four different classifications of bone, determined by their shape. Long bones are shafts with ‘heads’ on both sides. Our limbs contain mostly long bones. Short bones

The spinal cord is a major channel in the body where motor and sensory information travels from the brain to the body. It has white matter that surrounds a central gray matter. The gray matter is where most of the neuronal cells are located. Injury to the spinal cord will affect the conduction of information across any part of the spinal cord where the damage is located (Maynard et al., 1997). This will often result in permanent disability of a certain muscle or region of the body (Meletis et al., 2008) and a loss of tissue where the damage is located (Peng et al., 2009). As of now, there is no treatment for spinal cord injury expect for steroids. All steroids can do is provide protect of the spinal cord from secondary injury for specific patients (Peng et al., 2009).
Scoliosis is a deformation of the spinal column. The classification for Scoliosis is when the spinal column is curved sideways. Usually in the shape of the letter c or s. Unlike Lordosis, which is an extreme inward curve of the spine; or Kyphosis, a forward curve of the spine. Scoliosis's exaggeration lies in the how it's slanted.

There is two divisions of the bones, the axial skeleton and the appendicular skeleton. The axial skeleton consists of 80 bones which include the skull, vertebral column, ribs and sternum. The skull considts of 22 bones. The cranium which cover the brain are made up of 8 bones and the facial is made up of 14 bones.
