Document Summary
Chir113 exam notes: define biomechanics: the study of the technically of movement of all living organisms, define kinesiology: the study of the mechanics of body movement, lumbar introductory biomechanics, typical features of a lumbar vertebra: Slender transverse processes that project laterally and slightly posteriorly. Superior and inferior articular processes: lumbar articulations: 2 superior articular processes = facets face medially and slightly posteriorly. 2 inferior articular processes = facets face laterally and slightly anteriorly: lumbar intervertebral disc: Made up of fibrocartilaginous tissue = slight movement. Receive nutrient via diffusion due to avascular nature aided by spinal motion. Consists of a annulus fibrosus and nucleus pulposus. The motion of a rigid body consisting of translation and rotational motion: ligaments: A tough short band of fibrous connective tissue that connects bone to bone: nerve roots: Each nerve root exits the spinal canal foramen through the intervertebral foramen below the corresponding vertebra. Spinal cord ends at l1/2: dermatomes:
