Weekly Blog (8/30)

This week, our class did a lab on an apple to learn about anatomical directions and body planes. As our teacher called out directions, we blindly worked on the apple with whatever previous knowledge we had about the body.

Below is the equipment we were given. One apple, one scapal, and fourth toothpicks.

Step 1: Stand your apple on the table with the stem up. Consider the stem the superior end of the apple.

Step 2: With your marker, draw a line to indicate the frontal plane of the apple. Label the line with an “F” near the stem.

Step 3: On the anterior surface of the apple, draw a dot about the size of a pencil eraser to the left of the midsagittal line (remember the correct anatomical position) that is approximately 3 cm inferior to the stem.

Step 4: That dot is superior and medial to the left anterior surface of the apple. Draw a small letter “c” opened to the anterior side.

Step 5: Contralateral to that “c”, along the right anterior surface, draw another “c” equidistant from the midsagittal plane and along the same transverse plane as the first “c”.

Step 6: Approximately 1cm inferior to the dot on the anterior surface of the apple, draw a small “o” about twice as large as the dot along the midsagittal plane.

Step 7: Slightly lateral and superior of the “o” draw two upside-down small question marks (without the dot underneath), each of which is equidistant from and on opposite sides of the midsagittal plane. The question marks should open toward the midsagittal plane.

Step 8: On the posterior side of the apple and superior to the transverse plane, draw a series of vertical lines about ½” in length.

Step 9: Place two toothpicks along the frontal plane slightly inferior to the “o”. The insertion points of the two toothpicks should be along the same transverse plane, and on opposite sides of the midsagittal plane.

Step 10: Place another toothpick slightly anterior to the coronal plane on the left side.

Step 11: Place another toothpick slightly anterior to the coronal plane on the right side.

Step 12: Now add another small dot about the size of a pencil eraser to the right of the midsagittal plane superior to the question mark on the right side and equidistant as the other dot.

Step 13: Draw a transverse line under the question marks and above the “o.” Then label it with a “T”

Step 14: On the posterior side, draw a midsagittal line from the stem to the plantar portion of the apple and label it “M”

Step 15: Make a picture of the anterior side of your apple.

Step 16:Make a picture of the posterior side of your apple
