Vertebral Column and Thorax
Introduction to Human Osteology Chapter 4: Vertebral Column and Thorax Roberta Hall Kenneth Beals Holm Neumann Georg Neumann Gwyn Madden Revised in 1978, 1984, and 2008 The Vertebral Column and Thorax Sternum Manubrium – bone that is trapezoidal in shape, makes up the superior aspect of the sternum. Jugular notch – concave notches on either side of the superior aspect of the manubrium, for articulation with the clavicles. Corpus or body – flat, rectangular bone making up the major portion of the sternum. The lateral aspects contain the notches for the true ribs, called the costal notches. Xiphoid process – variably shaped bone found at the inferior aspect of the corpus. Process may fuse late in life to the corpus. Clavicle Sternal end – rounded end, articulates with manubrium. Acromial end – flat end, articulates with scapula. Conoid tuberosity – muscle attachment located on the inferior aspect of the shaft, pointing posteriorly.

5. Vertebral Column
5. Vertebral Column. Human beings belong to a vast group animals, the vertebrates. In simple terms we say that vertebrates are animals with a backbone. This statement barely touches the surface of the issue. Vertebrates are animals with a bony internal skeleton. Besides, all vertebrates have a fundamental common body plan. The central nervous system is closer to the back than it is to the belly, the digestive tube in the middle and the heart is ventral. The body is made of many segments (slices) built to a common plan, but specialised in different regions of the body. A “coelomic cavity” with its own special plan is seen in the trunk region and has a characteristic relationship with the organs in the trunk. This is by no means a complete list of vertebrate characteristics. Moreover, some of these features may be shared by other animal groups in a different manner. Such a study is beyond the scope of this unit. Vertebrates belong to an even wider group of animals, chordates. It may be difficult to imagine that we human beings are in fact related to some the earlier chordates! However, we do share, at least during embryonic development, an important anatomical structure with all chordates. This structure is the notochord. The notochord is the first stiff, internal support that appeared during the evolutionary story. As we have seen in early embryology, it also defines the axis of the body. The vertebral column evolved around the notochord and the neural tube, and we see a reflection of this fact during our embryonic development. -
The Characteristics of Osteophyte Around Lumbar Vertebral Foramina Associated with Spinal Stenosis
Original Article https://doi.org/10.5115/acb.2019.52.2.143 pISSN 2093-3665 eISSN 2093-3673 The characteristics of osteophyte around lumbar vertebral foramina associated with spinal stenosis Thawanthorn Chaimongkhol1, Atiphoom Thiamkaew1, Pasuk Mahakkanukrauh2,3,4 1Faculty of Medicine, Chiang Mai University, Chiang Mai, 2Department of Anatomy, Faculty of Medicine, Chiang Mai University, Chiang Mai, 3Forensic Osteology Research Center, Faculty of Medicine, Chiang Mai University, Chiang Mai, 4Excellence Center in Osteology Research and Training Center (ORTC), Chiang Mai University, Chiang Mai, Thailand Abstract: Spinal stenosis most commonly occurs on lumbar vertebrae because of degenerative changes. This research studied the characteristics of osteophyte development in lumbar vertebrae foramina and association of osteophyte development with lumbar spinal stenosis. The total number of all levels of lumbar spines of subjects was 179 from 31 to 90 years of age. The vertebral foramen was divided into six zones. The prevalence and measurements of the length of osteophytes in the vertebral foramina were obtained. The prevalence and length of osteophytes in the posterior body zone were higher than the laminal zone, and higher than the pedicular zone, respectively. In each zone, the highest prevalence of osteophytes was at L5, except for the inferior posterior body zone that the highest prevalence is at L4. The length of osteophyte was also in same direction as the prevalence. The prevalence of osteophytes among six zones of each level were compared, and found, in L1 to L4, the inferior posterior body zone generally had the highest prevalence, except in L5, the superior posterior body zone had the highest prevalence. -

Anatomy of the Spine
12 Anatomy of the Spine Overview The spine is made of 33 individual bones stacked one on top of the other. Ligaments and muscles connect the bones together and keep them aligned. The spinal column provides the main support for your body, allowing you to stand upright, bend, and twist. Protected deep inside the bones, the spinal cord connects your body to the brain, allowing movement of your arms and legs. Strong muscles and bones, flexible tendons and ligaments, and sensitive nerves contribute to a healthy spine. Keeping your spine healthy is vital if you want to live an active life without back pain. Spinal curves When viewed from the side, an adult spine has a natural S-shaped curve. The neck (cervical) and low back (lumbar) regions have a slight concave curve, and the thoracic and sacral regions have a gentle convex curve (Fig. 1). The curves work like a coiled spring to absorb shock, maintain balance, and allow range of motion throughout the spinal column. The muscles and correct posture maintain the natural spinal curves. Good posture involves training your body to stand, walk, sit, and lie so that the least amount of strain is placed on the spine during movement or weight-bearing activities. Excess body weight, weak muscles, and other forces can pull at the spine’s alignment: • An abnormal curve of the lumbar spine is lordosis, also called sway back. • An abnormal curve of the thoracic spine is Figure 1. (left) The spine has three natural curves that form kyphosis, also called hunchback. an S-shape; strong muscles keep our spine in alignment. -

This pairs at each level. In between each vertebra there is a disc is known as a nerve root injection, and can both which acts as a shock absorber and spacer. improve symptoms and aid diagnosis. The spinal nerves are like electrical wiring, providing Nerve root injections or ‘nerve root blocks’ are used to signals to areas within the leg. These control sensation and reduce pain in a particular area if you have lower limb pain movement but can cause pain when they are affected. such as sciatica. The injection is done in Radiology.
