The body is deeper in front than behind, and prolonged canada goose uk telephone number downward anteriorly so as to overlap the upper and front part of the third vertebra. Injuries to C 1 and C 2 can result in a loss of many involuntary functions including the ability to breathe, necessitating breathing aids such as ventilators or diaphragmatic pacemakers. buy canada goose jacket cheap

Canada Goose Coats On Sale C4 Cervical Vertebra Quadriplegia and breathing difficulty The fourth cervical (neck) vertebra from the top. Injuries above the C 4 level may require a ventilator for the canada goose outlet person to breathe properly. Canada Goose Coats On Sale
C5 Quadriplegia with some shoulder and elbow function 5th cervical vertabrae down from the base of the skull, found in the neck. C5 injuries often maintain shoulder and biceps control, but have no control at the wrist or hand.
C5 to C8 injuries Corresponding nerves control the arms and hands, a person with this level of spinal injury may still be able to breathe on their own and speak normally.
C6 Cervical Vertebra Quadriplegia with shoulder, elbow, and some wrist function The sixth cervical (neck) vertebra from the top. The next to last of the seven cervical vertebrae. An injury to the spinal cord between C6 and C7 vertebrae is called a C6 7 injury. These injuries generally allow wrist control, but no hand function.
C7 Vertebra Prominens Quadriplegia with shoulder, elbow, wrist, and some hand function The most distinctive characteristic of this vertebra is the existence of a long and prominent spinous process, hence the name vertebra prominens. In some subjects, the seventh cervical vertebra is associated with an abnormal pair of ribs, known as cervical ribs. These ribs are usually small, but may occasionally compress blood vessels (such as the subclavian artery) or nerves in the brachial plexus, causing unpleasant symptoms. C 7 and T 1 can straighten their arms but still may have dexterity problems with the hand and fingers. Injuries at the thoracic level and below result in paraplegia, with the hands not affected.
C8 Quadriplegia with normal arm function; hand weakness Although there are seven cervical vertebrae (C1 C7), there are eight cervical nerves (C1 C8). All nerves except C8 emerge above their canada goose freestyle vest uk corresponding vertebrae, while the C8 nerve emerges below the C7 vertebra. In other words C8 is a nerve root not a vertebrae.
The thoracic vertebrae increase in size from T1 through T12 and represent the canada goose black friday offers 12 thoracic vertebrae. The thoracic vertebrae are situated between the cervical (neck) vertebrae and the lumbar vertebrae. These thoracic vertebrae provide attachment for the ribs and make up part of the back of the thorax or chest. Damage or SCI’s above the T1 vertebra affects the arms and the legs. Injuries below the T1 vertebra affect the legs and trunk below the injury, but usually do not affect the arms and hands. Paralysis of the legs is called paraplegia. Paralysis of the arms AND legs is called quadriplegia.
