Patrick Elder. Basics. How do we divide the vertebrae of the vertebral column, and how many are there?. 7 cervical, 12 thoracic, 5 lumbar, 5 sacral and the coccyx.. From where do the spinal nerves originate, and how are they named?. 1. Muscles of the Thoracic Wall. a. . intercostals (external/internal). * L: between ribs. * A: elevate/depress rib cage (breathing). Origin:. . Inferior border of rib above. . Vertebral Column (Spine). Extends from the skull, which it supports, to the pelvis, where it transmits the weight of the body to the lower limbs. The spine is formed from 26 irregular bones connected and reinforced by ligaments in such a way that a flexible curved structure results. P. repared. by . M. uhamma. d. Mustafa . yousafzai. Anterior triangle. The anterior triangle is situated at the front of the neck.. It is bounded:. Superiorly. – Inferior border of the mandible (jawbone). Chapter 8. Introduction. The notochord and vertebral column define the long axis of the body, offer sites for muscle attachment, prevent telescoping, and support body weight.. The notochord is a long, continuous rod of fibrous connective tissue wrapping a fluid filled core.. Vertebral Column (Spine). Extends from the skull, which it supports, to the pelvis, where it transmits the weight of the body to the lower limbs. The spine is formed from 26 irregular bones connected and reinforced by ligaments in such a way that a flexible curved structure results. Over 600 in the human body. Allow the skeleton to move. To cause movement, both ends of each muscle must be attached to bone. Origin or proximal attachment – the attachment closer to the center of the body. Convergent. (. pectoralis. major). Parallel.
