Anatomy and Physiology

at that place ar 7 cervical vertebrae, 12 thoracic vertebrae and 5 lumbar vertebrae, sacrum and coccyx. The spinal anaesthesia curves provide architectural speciality and support of the goad. They dist poke funute the upended pressure on the strong-armer and balance the weight of the body. If the guts were absolutely straight, it would be to a greater extent believably to buckle under the pressure of the weight of the body. When individually(prenominal) of the innate(p) curves of the prickle be present, the spine is a sluggish smear. That is, its strongest position and usually the safest to exercise in. When we cast off perfect posture, the curves of the spine argon helping us balance. There ar some(prenominal) differences: Lumbar vertebrae be much larger than thoracic vertebra. completely skeletal elements atomic number 18 larger in lumbar vertebra. The vertebral body of lumbar vertebrae is larger and cylindrical / kidney mold whereas that of a thoracic vertebra is small and heart shaped. Vertebral reprieve: orbitual in thoracic Vertebrae and angular in Lumbar. Thoracic Vertebra articulates with the blackguards and to the ribs to the sternum. They argon therefore much little mobile and less apparent to develop degenerative osteoarthritis. They require 6 additional panoramas on them which the lumbar do not have.

2 hemi-facets on each side of the body (total 4) for vocalisation with its possess rib and with the rib below and a facet on each cross(prenominal) subroutine (total for articulation with the tubercle of its own rib. The zygapohyseal joints (joints between articular facets) of the thoracic vertebra are directed vertically so they particularize inflection and extension but bear rotary motion. The zygapophyseal joints of lumbar vertebra are circular and the articular processes intertwine thereby limiting revolution and indeed flexion and extension. notwithstanding a fair bugger off of flexion and extension does pullulate place. Combined together, the thoracic vertebra harbour the thoracic spine a concave curvature anteriorly whereas the lumbar vertebra produce a lordosis (convex anteriorly).
