Vocabulary for This Unit on Quizlet

Our skeletons are divided into axial and appendicular skeletons. The axial is our skull, spine, and ribs. The appendicular is everything else.

It may seem like a lot at first but make be sure you can locate and describe all the following bones: humerus, radius, ulna, scapula, clavicle, sternum, vertebrae, ribs, pelvis, femur, tibia, fibula, and patella.

The joints between bones let them move so we can move too. Be sure to know the types, locations, and functions of the common joints.

Bones themselves are living tissue made of straw-like osteons and honeycombed trebecullae. Be sure to know what these look like and why they are important.

The cells of bones help them adjust and maintain their shape. Osteoblasts build bones while osteoclasts destroy bones.

The skull is made of many fused bones. Be able to locate the temporal, frontal, sphenoid, occipital, zygomatic, maxilla, mandible, ethmoid, lacrimal, vomer, nasal, and palatine.

The vertebrae have their own bone names. The top 7 small vertebrae are the cervical, the next 12 are thoracic, and the last 5 are lumbar. Under that are fused vertebrae that make up the sacrum and our left-over mammalian tail, the coccyx. Also know the individual parts of a vertebrae including vertebral foramen, transverse process, and body.

The ribs are divided into the top 7 true ribs (vertebrosternal), the next 3 are false (Vertebrochondral), and the last 2 are also false (vertebral). Know why they are named that and know the parts of the sternum (manubrium, body, and xiphoid process).

The hands and feet have similar bones. Know and be able to identify your tarsals, metatarsals, carpals, metacarpals, and phalanges. The wrist and ankle bones are complicated but if you learn them too I'll give you bonus points :)

Those osteoblasts are going to be working hard in this unit repairing bone breaks. Be able to describe a simple break, compound, comminuted, compressed, depressed, impacted, spiral, and greenstick fracture.

We'll only discuss three diseases of the skeletal system in class although you'll be free to research more - know the symptoms, causes and treatment of osteoporosis, osteomalacia, and pagets disease.
