Objectives Describe the regions and curvatures of the vertebral column and the number of vertebrae in each region Describe the basic components of a typical vertebrae . 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?. Vertebral Column Your Subtitle Goes Here Posture Vertebral Alignment Does it really matter? Yes it does! Postural Curves Convex & Concave • the reference point is the posterior aspect • 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. POSTCRANIAL SKELETON - . I. AXIAL SKELETON. S. S. Sumida.  . INTRODUCTION.  . The axial skeleton is generally considered one of the hallmark features of vertebrates; it is after all, the namesake of the group. However, the idea that the group was defined by having vertebrae or a vertebral column turns out to be an oversimplification.. 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.. . &. Joints of Bones of Trunk. By. Dr.Pardeep. Kumar. Arthrology. . It is a science concerned with the study of joints.. In order to serve the purposes of protection and movement, the bones must be joined together one another by connective tissue at different parts of their surfaces, and such connections are termed Joints or Articulations.. 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. Together with ribs and sternum provide about two-fifths (40%) of the height of the body. Composed of 33 (26) different bones. Encloses and protects the spinal cord. Supports the head. Lower vertebrae supports the weight of the entire upper body. Vertebral Column. 26 bones. : . Vertebrae (24). Sacrum. Coccyx (. tailbone).
