BIOL 2010 Lecture Notes - Lecture 3: Cervical Vertebrae, Articular Processes, Lumbar Vertebrae
Document Summary
206 bones on average in the human body. Function: support, protect, levers for movement, storage for inorganic salts and fats, the site of blood cell and some hormone replacement. Axial skeleton: bones that make up the skull, vertebral column. Skull: 22 bones face and cranium, most of the bones in the skull (with the exception of the mandible) are connected to each other through immoveable joints called sutures. Hyoid bone indirectly connected to skull by ligaments that attach to the styloid process of the temporal bones and acts as a moveable base for the tongue. It is the only bone in the body that does not directly articulate with another bone. Lumbar veryebrae have larger bodies than the other (indicative of their primary function of weight- bearing: two more bones complete the spinal column: the sacrum and the coccyx. Both are formed from the fusion of vertebrae during development (5 and 4 vertebrae, respectively).
