Right bone vs. Left bone

  1. 0
    UGH my brain is melting. I've been studying for my anatomy exam like crazy and I still can't wrap my brain around the left bone vs. the right bone. Does anyone have an easy neat tricks to remember the difference?

    Specifically: Clavicles, scapulae, tibia, fibula, ulna, radius

    Hi:
    I realize it has been a while since I was in nursing school....But unsure what you mean regarding right bone vs. left bone?

    Hmm...maybe I didn't word that right. The exam is going to have a bunch of bones around the room and we have to go around and identify them and label their views (anterior, posterior, medial, lateral..) and indentify what sid of the body they're on. ie RIGHT fibula or the LEFT fibula?

    You smell what I'm steppin' in?

    RULES FOR LEFT AND RIGHT


    1. Humerus – hold the bone so that the capitulum and trochlea face YOU (anterior)

    -if the head faces left – it is a left humerus


    1. Ulna – face the trochlear notch away from you (U-shaped process) and look at the olecranon

    -ask yourself – on what side is the radial notch?
    -if it is on the right – it is a right ulna

    3. Radius – orient the bone with the round head UP and the distal end DOWN
    -look at “bumps” at the distal end

    -look for the styloid process at the distal end
    -if it is on the right side – it is a right radius

    4. Scapula – hold the bone with the spine facing YOU and the apex facing DOWN
    -if the acromion faces left – it is a left scapula
    -NOTE: the corocoid process is spelled with a “c” and so is “scapula”

    5. Femur - the head must face IN and the lesser trochanter must be on the BACK side of the bone
    -so hold the bone so that the head is on top and the trochanters are on the BACK surface of the bone
    -if the head faces left – it is a left femur

    6. Tibia – hold the bone so that the intercondylar eminence is towards the top and you are looking at the tibial tuberosity
    -if the medial malleolus on the distal end is on the left side – it is a left tibia

    7. Clavicle – a. point the flat sternal end toward the midline
    b. the clavicle bulges OUT then IN
    c. the conoid tubercle must point DOWN



    TELLING THE TYPES OF VERTEBRAE APART



    1. Cervical – three holes, forked spinous process
    2. Thoracic – one hole, long, thin spinous process
    3. Lumbar – one hole, processes are thick and large
    4. Atlas – looks very different, almost like a circle
    5. Axis – look for the “dens” near the body


    Corocoid – “c” in scapula
    Coronoid – “n” in ulna (or mandible)
    Conoid – is the clavicle






    hope this helps
