It will be graded on a 100 point scale but there will be 140 points possible if you get all the bonus questions correct as well. I will deduct 40 points if you have to use your notes and worksheets and 60 points if you have to use your book. In other words, if you use your notes only you can still earn a 100 (A+) and if you use your book (because you did not do your homework) you can still earn an 80 (B-). If you study a lot you can earn up to 40 bonus points.

The first set of flash cards we will make will be of the skeletal system.
Directions:
Write each of the terms on figure 6-9, page 147, on one side of an index card.
On the other side of the card write the common name that you would know it by.
On this side, also write the nember of those bones that the body has.
For example: tarsal bones on one side and ankle bones (14 total, 7 on each side) on the other.
There should be 36 cards in assignment but we will eventually add to this number as we learn some of the names of the vertebrae, face, cranium, hands, and feet.
LATER we will add to these cards so leave some space to write additional details in the future.
(Such as type of joints or muscles that are attached)
Using the cards:
Keep the cards together in a zip lock bag and label the bag with the subject.
Flip through the cards to learn the information on the cards.
You can shuffle the cards so that you are not learning them in a particular order.
When you come to a card you do not know, put it in a seperate pile. These are terms you need to study more.
You can also try matching each term that part of your skeleton or arranging them on a table to form a skeleton.

Introduction to anatomy and physiology blog
| This is the blog for Mr. Vaught's Anatomy and Physiology class. All students enroled in the class will be given a link/address to this blog and are encouraged to check the blog on a regular basis. It will be especially helpful if you are for any reason absent from class. All parents are also encouraged to frequent the site to see what we are currently working on. Many of these posts are given in class as handouts and homework assignments. You can copy and paste from this site to a word document and do your homework on a computer instead of on paper. You can then email the completed assignment to me (preferred) or bring it to me on a flash drive with your name and period as the file title. This is highly endourged as it will save the school paper and toner. I have posted most of the assignments that were assigned the first 2 weeks of the 2009 fall semester. In addiition to these we have also had daily journals that should have been answered in class as well as one quiz and one test on chapter 1. The first assegnment for chapter 2 on chemistry is the previous post. It is due on Tuesday, Sept.8th. If you have questions that are not answered here, please ask them in class or email me at (jvaught@hardingfinearts.org). If you do facebook, feel free to friend me through the same address. (If you try to friend me through my other facebook account I will not accept it. Please do not take this personally) |

sample yoga pose
| The following is the an example of instructions of how to do a yoga pose using anotomical positions. The pose is called the half-moon pose. 1. Stand with both pes touching at the halux and the calcaneus, keeping the lumbar and dorsum straight and the upper limbs pressed slightly against the sides with the palms facing medially against your femor. 2. Bring your manos together ventrally, palmar regions touching, and pressing slightly medially. 3. Contract your diaphram, moving it inferiorally, and move your manos in the superior direction while keeping them pressed slightly together. 4. Arch your trunk backward at the lumbar, dorsum, and cervical regions, keeping your brachium next to your cercical and cranial region, tilt the cephalon back. Keep your popliteus straight while holding this posture. 5. Slowly return to anatomical position. |
homework and review
| Read the summary outline on page 24-25. Then answer all the review questions on page 26-27 (questions 1-30). The chapter 1 exam will be comprehensive so any information from prior homework assignments and quizzes may be tested. |
quiz of anatomical terms
There will be a quiz on all the anotomical landmarks, regions, directionsal terms, and planes of section (see figures and tables page 17-20). The quiz will be mostly matching of the terms from figure 1-6 with a few short answer questions using the knowledge from the other figures and tables. |
yoga pose assignment
Assignment: Choose a yoga pose and learn how to perform it. Write the instructions on how to do the pose using at least 10 anotomical terms from chapter 10. These can include anotomical positions, directions, and anotomical landmarks. Class will then meet in the dance studio where we will take turns teaching the poses to the rest of the class. Grading: 10 poiints will be awarded for each anotomical term used. 5 points will be awarded for teaching it to the rest of the class on the proposed date. |
chap 1 worksheet
Anatomy and physiology reading and study guide for chapter 1, simplified. Assignment: Read and outline chapter 1. Read the chapter objectives first so that you have an idea of what the most important themes will be. Because this is a college level text, the vocabulary is very dense and there is a great amount of information presented at once. Many of the details are beyond the scope of this course so I do not expect you to learn all of them but would like you to be exposed to all of them by reading it at least once. The following is a list of things that I believe are the highlights of the chapter that we should all learn. As you read and outline you should focus on answering the following questions and defining the following terms. (Page #s are in parenthesis)
i. Anatomical ii. Supine iii. Prone
i. Anterior ii. Posterior iii. Ventral iv. Dorsal v. vi. Inferior vii. Medial viii. Distal ix. Lateral x. Proximal xi. Caudal xii. cephalic xiii. Cranial xiv. Superficial xv. Deep
i. Ventral 1. Thoracic (21) 2. diaphragm (20, 21) 3. Abdominopelvic (22)
i. Transverse ii. Frontal/coronal iii. Sagittal/midsagittal
What is the difference between X-rays, CAT scans, MRIs, and ultrasounds? (23) In addition, you should learn the regions of the body in table 1-1, page 16, and the anatomical landmarks in figure 1-6, page 17. |
