Bones, Osteo & Artho

Bones, Osteomechanics and Arthokinetics

QuestionAnswer
Physiology and structure of bones calcified connective tissue consisting of osteocytes (bone cells) in a matrix of ground substance and collagen fibers
Long bones longer than they are wide - include the clavicle, humerus, radius, ulna, femur, tibia, fibula, metacarpals and phalanges
Short bones are found in the wrist and ankle and are shaped like cuboids
Flat bones include ribs, sternum, scapulae and bones in the vault of the skull
Irregular bones include bones of mixed shapes, such as bones of the skull, vertabra and coxal bones
Sesamoid bones develop in certain tendons and work to reduce friction on the tendon, thus protecting from excessive wear
Osteokinematics voluntary movements - flexion, abduction, rotation
Component motion accompany active motion but are not voluntary - upward rotation of the scapula, clavicular rotation that occurs with shoulder flexion, rotation of the fibula that occurs with ankle motion
Arthokinematics joint play between joint surfaces as well as distendibility "give" in a joint capsule (distraction, sliding, compression, rolling, spinning of joint surfaces)
