BSC 181 1st Edition Lecture 16 Outline of Last Lecture I. Intramembranous versus endochondral ossification and growth platesII. Types of FracturesIII. Bone RepairOutline of Current Lecture IV. Osteomalacia vs RicketsV.Bones of the CraniumVI. Bones of the faceVII. Curves of the SpineCurrent LectureOsteomalacia vs RicketsOsteomalacia: these bones are soft and weak because of the lack of calcium, and there is pain when weight is put on themRickets: this is when the legs have a bowed shape, the bone is soft, and the bone ends are enlarged and unusually long. Caused by vitamin D deficiency and/or a deficiency in calcium. Bones of the craniumFrontal Bone, Parietal bones (2), Occipital bone, Temporal bones (2), Sphenoid bone, Ethmoid Bone-only need to be familiar with cranial bonesBones of the faceLacrimal bones (2) up by the tears, Palatine bones (2), Vomer, Inferior nasal conchae (2), Mandible* Maxillary bones* (maxillae) (2), Zygomatic bones (2), Nasal bones (2)-only need to be familiar with the bones of the faceThe curves of the spine and when they appearThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.Cervical Curvature: found in 7 vertebrae, C1 through C7 Thoracic Curvature: found in 12 vertebrae, T1 through T12Lumbar Curvature: found in 5 vertebrae, L1 through L5Sacral Curvature: 5 fused vertebrae (sacrum)It is important to remember that there are natural curves to the body and that these are okay. There are however some extreme curvatures that are not healthy. Such as Kyphosis which is often seen in the older generation. It is a thoracic curvature that is dorsally exaggerated. It’s like the hunchback of Notre Dame back. The other that is not normal is the Scoliosis. If you look at someone’s back and the spine looks like an S, then that person probably has scoliosis. This is a lateral curvature. Another abnormality is called Lordosis. This occurs with pregnant women or when someone carries a large load up front. This is a lumbar
