Describe the Anatomy of the Spinal Cord

Instruments such as hooks rods and wire are attached to the spine to realign the bones of the spine and keep them secure following spinal fusion. The primary injury of the spinal cord rarely affects the entire cord but the patho of secondary injury may result in damage that is the same as mechanical severance of the cord.

Spinal cord ischemia and infarction occur less frequently than cerebral infarction but result in significant mortality disability and reduced quality of life in survivors.

. These neural pathways represent the communicating highways of the CNS. Spinal cord stimulation SCS therapy is used to treat different kinds of chronic pain pain lasting six months or more. Mechanical forces toxic and ischemic from lack of blood flow.

The brain and spinal cord are protected by the bones of the skull and vertebral column and by cerebrospinal fluid a colorless fluid produced by the brain which cushions the brain and spinal cord within the posterior dorsal cavity. Spinal cord injury can be traumatic or nontraumatic and can be classified into three types based on cause. 111 Describe the roles of agonists antagonists and synergists Interactions of Skeletal Muscles in the Body The moveable end of the muscle that attaches to the bone being pulled is called the muscles insertion and the end of the muscle attached to a.

The cell death that occurs immediately in the original injury and biochemical cascades that are initiated by the original insult and cause further. The spinal cord and various cranial nerve nuclei. Neural pathways anatomy The central nervous system CNS contains numerous nerve fibers that group together to form pathways between its various parts.

Complete cord dissolution occurs through autodestruction of the cord by hemorrhage edema and the presence of metabolites and norepinephrine. The damage can also be divided into primary and secondary injury. The cerebral aqueduct of Sylvius is located in the midbrain and joins the third and fourth.

Descending tracts are the pathways by which motor signals are sent from the brain to the spinal cordThey are also called motor tracts due to their involvement in movement coordination. This can include pain in the back legs and feet or a combination of different pain areas. Midbrain Anatomy The midbrain connects the pons and cerebel-lum with the forebrain and can be divided into a ventral part the tegmentum and a dorsal part the tectal or quadrigeminal plate Figs 2 3.

Just as the brain and spinal cord make up a continuous uninterrupted structure the cranial and spinal cavities that house them are also continuous. Causes of a Spinal Cord Injury Spinal cord injury occurs when something interferes with the function or structure of the cord. Modern imaging techniques and refined diagnostic criteria have increased awareness of spinal cord ischemia and enhanced our understanding of its pathophysiology.

They can be located solely within the brain providing connections between several of its structures or they can link the brain and. When people are injured they are often told that they have an injury at a given spinal cord level and are given a qualifier indicating the severity of injury ie. Vertebral Column Developmental anomalies pathological changes or obesity can enhance the normal vertebral column curves resulting in the development of abnormal or excessive curvatures Kyphosis also referred to as humpback or hunchback is an excessive posterior curvature of the thoracic region.

This can develop when osteoporosis causes weakening and erosion of the. This can include consequences of a medical illness or trauma resulting in over stretching the nerves a bump the bone of the vertebra pressing against the cord a shock wave electrocution tumors infection poison lack of oxygen ischemia cutting or. Resulting in anoxia and infarction of the.

These tracts can be classified by their structural arrangement into lateral and medial tracts. Spinal Cord Injury Levels Classification.
