Presentation Transcript

  1. HBS 1.2.1

  2. Get out • Binder • Graphic organizers • Maniken • Anatomy coloring books

  3. Label these bones on your skeletal system graphic organizer • o  Mandible • o  Maxilla • o  Zygomatic Process • o  Frontal Bone • o  Temporal Bone • o  Occipital Bone • o  Parietal Bone

  4. Label these muscles on your muscular system graphic organizer • o  OrbicularisOculi • o  OrbicularisOris • o  Temporalis • Next to them, write the basic functions

  5. #1- Building the Temporalis Muscle • Where do you think it goes? • This region is referred to as the temporal fossa. Fossais a term used to describe a flat surface on a bone.

  6. #1- Building the Temporalis Muscle • Muscles will be built using terra cotta clay. • Take a ball of terra cotta clay the size of a jawbreaker and flatten it into a fan. • Slip the point of the fan through the zygomatic arch and onto the coronoid process of the mandible (the superior ridge at the top of the mandible). Flatten the clay until it sits neatly on the side of the head and behind the ear.

  7. Function of Temporalis Muscle • Place the fingers on the temples as you clench and unclench your jaws. You should feel the temporalis contract and relax.

  8. This is skeletal muscle • What do we know about skeletal muscle and its appearance?

  9. #2- Adding the Fat • Take a small portion of yellow clay about the size of a raisin and roll the clay into a ball. • Place this round ball into the cheek of the maniken. Fat provides the round look of the cheeks.

  10. Fat • There are also pads of fat behind the eyes. Take a small portion of yellow clay (a bit smaller than the cheek fat) and roll the clay into a ball. • Flatten the ball on the desk and use the wire tool to divide the circle into two half moons. • Place these fat pads in the eye socket leaving a small amount of space in between the two pads. The pads are oriented in the same direction as your eye lids.

  11. #3- Building the Eye • Choose a color of clay for the maniken’seye • Roll a raisin-sized ball of clay using the eye color. • Slightly flatten the ball as you place it in the eye socket over the fat pads. Leave a small portion of the fat extending from the top and the bottom.

  12. OrbicularisOculi • The sphincter muscle used to open and close the eye. • Where do you think it should go?

  13. Building the OrbicularisOculi • Form a 1 & 1/2” worm of terra cotta clay (about the thickness of a pencil). • Turn the string into a circle. • Flatten the string with your hand. This “O” will form the outer portion of the muscle.

  14. Inner Eyelid • Place this “O” off to the side. • You will create the inner eyelids before they place the muscle on the eye. • Roll a small raisin-sized ball of terra cotta clay. Flatten this piece into a disk. Cut the disc into two equal halves as you did with the fat pad. • Place one half over the top part of the eye and the other half over the bottom part of the eye. This will form the inner eyelid. A good portion of the eye color should be visible.

  15. Placing the OrbicularisOculi • Now take the “O” you created previously and place it over the eye. • The inner eyelid should be centered in the hole of the donut. • Use a pencil to create a pupil.

  16. Striations • Use the wire loop or a pencil to gently tease eyelashes from the eyelids. • Show the function of this muscle. • The striations are oriented in a ring- the muscle shortens to squeeze the eye shut.

  17. #4- Building the Mouth • Build the OrbicularisOris, the sphincter muscle used to purse the lips (often known as the kissing muscle). • Where do you think this goes?

  18. Form a jawbreaker sized ball of terra cotta clay. • Flatten the ball slightly to form a disc. • Place the disc over the tip of your finger and create a small dome in the disc. • Attach the domed disk over the mouth of the Maniken® and attach the outside edges of the muscle. Curl the excess portion of the disk around to the inside of the midline.

  19. Cut a slit for the mouth, dividing the disc into upper and lower halves. • With the fingertips or the wire tool, roll the upper and lower edges of that slit into lips. Use your finger to smooth the clay around the lips. They may look silly, but keep playing with them!

  20. ObicularisOris • Show me the function!

  21. Last, but not least • 1. Be sure you have the functions and locations on your graphic organizers. • 2. Look around, are all the manikens alike? Why or why not?
