    So, this is week 7 of gross anatomy at UCLA SOD; I thought it'll be interesting to share with you everything I'm responsible to learn for the three lectures that we had this week - and this isn't even a complete list, I'll have to do that tomorrow morning. For those pre-dents, it'll give you a glimpse of what dental school is like... go figure!



    Scalp

    Skin (epidermis, dermis)

    Cutaneous layer

    Galea aponeurotica

    Loose connective tissue

    Periosteum

    eyeball itself: ...?





    Orbital nerves

    Optic (CNII)-

    Oculomotor (CNIII)–superior branch (innervate levator palpebrae superioris, sup. Rectus muscle)

    -inferior branch (innervate inf. rectus, medial rectus, inf obliq muscle)

    Trochlear (CNIV) (innervate superior oblique muscle)

    Trigeminal (V1) – opthalmic –frontal – supratrochlear

    - medial branch of supraorbital

    - lateral branch of supraorbital

    - lacrimal (innervate lacrimal gland)

    Abducens (CNVI) – (innervate lateral rectus)



    Orbital artery

    Internal carotid artery - Opthalmic artery: lacrimal artery, anterior ethmoid artery, posterior ethmoidal artery, supratrochlear, supraorbital artery (no anastomoses)



    Would I trade this for anything else in my life?

    ...

    No! Love every bit of it! No matter how dense, difficult, time consuming, or perverse.

    thanks...

    you mean this is all information that you covered in one class period? or what? one exam unit? or do you mean for all 7 weeks?

    can you specify?

    All this is from handouts, assumed knowledge that we should pick up, and three hours of lecture in week 7, and we get a quick oral quiz on Monday.

    hopefully this motivates any pre-dents who haven't taken Anatomy yet to find a way to fit in before dental school. I'm glad I've taken it already.
    I recognize probably 90% of those terms already. hopefully that will take a little pressure off since there are probably 1000 more terms to learn later.

    So we have to know anatomy...it is strictly memorization. Granted it may be more in depth than the anatomy course I have taken, but bring it on!

    When your medial rectus effs up, the result is lateral strabismus.

    What is that pneumonic for?

    TucsonDDS, do you go to UofA?

    Thanks

    The stuff the OP posted looks like stuff you would need to ID on the cadaver in lab. For the lecture part of the course, you would need to know how all of these structures work in conjunction with one another. For our tests, we usually got case studies with symptoms having to do with the head and neck and we'd have to answer questions about what nerves, vessels, muscles would be affected and what not. We'd get essays too. Anatomy is not hard, it is just VERY time consuming because of the gazillion structures you have to know.

    I'm so glad anatomy is over...well, until the boards that is... :D

    Trochlear
    Trigeminal
    Abducens
    Facial
    Auditory

    anatomy is not pure memorization dont kid yourself. if you don't understand where the nerves are coming from and are going.. then you going to screw urself in the end.. and i wish i was still in anatomy i enjoy high intensity stuff better.

    I knew pneumonic wasn't right but I am a terrible scrabble player. Actually I can barely spell my name sometimes. Unfortunately they take off for spelling in our dental anatomy class.

    And I do believe that yours is a little better. I have a sicker one but I don't think I should post it here,

    I took some post grad classes at UofA but I actually graduated from NAU. I live in Buffalo now for school but I am sure I will be back in Tucson after school. Unless I can talk my wife into somewhere else.

    Are you in Tucson??

    Don't worry, you will have kind of a 'Deja Vu' with Pathology in the second year.

    So true. To truly understand where structures lie you must know how relationships. E.G. Where is the phrenic nerve with respect to the anterior scalene, etc... These are the things that will stay with you and help when you encounter a body with slightly different anatomy. Everyone's different.

    Anatomy was an awesome class.

    My favorite elective dissection was when I snipped the penile suspensory ligament in an effort to give my cadaver a stronger, longer member.

    That is what I meant, my anatomy was combined with physiology. I don't pretend to think that it was as in depth as yours. I am just saying, anatomy is anatomy. You have to memorize. I have found that memorizing information is easier than conseptualizing material and having to apply that material to new situations which have not been studied before.

    I found conceptually understanding the material automatically helps me memorize the damn structures - it may be more time consuming, but it surt beats the boredom of pure memorization process.

    I'll update you guys with week 8 once this week is over. You probably don't care that much about what actually happens in week 8, but you know what... posting this **** really helps me learn. So, let me be selfish a bit.

    you guys want the best advice for prepping for anatomy and physio?

    take greek and latin.

    and to jk517: what no levator labii superioris alaeque nasi ??!!

    No, I meant Procerus and Levator Labii Superioris Alaeque Nasi. I believe digastric and stylohyoid belong to the submandibular triangle of the anterior triangle. And the stapedius lies in the posterior wall of the middle ear space. :p How is Case treating you?

    I never quite understand what the heck that muscle is for or how the heck that is named, so I just skipped and assume it's not that important. Can you enlighten me here?

    If you went to UCSF you'd know, I'm taking the exact same stuff as you and I'm not even in dental school yet, but I will be soon make no mistake about that, at least that's what my brother said last night while we were necking.

    Are you just doing the head and neck? or will you move on to the rest of the body?
    the A&P class that I am in now is doing most (but by no means all) of what you have covered in regrads to muscles and bones. we will go on to nerves and the rest next term..

    We did the limbs, thorax, and abdomn in the first 5 weeks already. Now we are just doing head and neck.

    For me, this is the key to why anatomy in dental school is so different from what I had in undergrad. Learning things by system (bones, then muscles, etc.) is much simpler because you basically just learn to memorize where everything is. In dental school you cover topics by region of the body. For example in gross, you cover the arm, forearm, and hand as complete functional units. In head & neck you will do the facial muscles, neck, TMJ, cranial fossae, etc. When you learn one topic, you must know EVERYTHING about it -- bones, borders, muscles & actions, nerves & innervation, arteries & veins, lymphatic drainage. This integration takes things to a whole new level -- you must learn how all the pieces relate to each other and fit together. I hope this helps you out, maybe you can start thinking this way in your undergrad class... I definitely wish I had learned things differently the first time around, it would have made my life much easier now!

    Interesting point on the systemic learning.

    The hard part of anatomy for me is the nervous system and then to understand how the nervous system sort of links everything together, and in order to do so, it has to have PANS, SANS, ganglions, preganglions, post-ganglions, different kinds of fibers, and etc. On a cadaver, they all look alike. Arteries are, for the most part straightforward - it carries blood, and it anastomoses. But nerves is a whole new world.
