• cortex of bone is white on a CT
• medulla of bone is grey on a CT as less dense
• bone on an MRI is black
• skeletal muscle is brighter on CT than fat
• dorsal = posterior
• ventral = anterior
• diaphram 


  muscle that seperates the thoracic and abdominopelvic cavities
• organs in thoracic cavity

  heart, lungs, esophagus, trachea, thymus
• the lungs are lateral to the heart
• the heart is deep and posterior to the sternum
• the esophagus is posterior and ventral to the heart
• the trunk incluides the thorax, abdomen, pelvis, and perineum
• bones in pelvic brim:

  sacrum, ilium, pubis
• what type of joint unites the two hip bones anteriorly

  cartilagenous
• what joint type unites each hip bone with the sacrum posteriorly

  synovial
• axial skeleton contains:

  flat and irregular bones
• upper limbs of the appendicular skeleton bones:

  short and long
• fibrous joints unite bones with fibrous connective tissue, without a joint
• cartilagenous joints unite bones with cartilage without a joint cavity
• in synovial joints, bones are held together by ligaments adn an articular capsule, articulating bone surfaces are covered by articular cartilage, and there is a joint cavity with synovial fluid
• shoulder girdle bones

  clavicle and scapula
• bones between elbow and wrist

  radius and ulna
• thumb is lateral to little finger
• palmar surface is anterior and ventral
• carpal bones are proximal and superior to phalanges
• deep facia has DICT
• neurovascular bundle

  nerve, artery, one or more veins, and lymphatic vessels
• blood vessels are hollow, and nerves are discoloured and not hollow
• femur articulates acetabulum proximally and tibia and patella distally
• nearly all joints of the lower limb are synovial
