Your thirst and hunger centers tell you that you are dehydrated and hungry. You decide cold water and chicken wings will satisfy such desires. Trace the path of “the wings” from the mouth to the anus, listing the path in as much detail as possible. Again, be very specific and very detailed including the absorption/elimination of nutrients/wastes.

Your thirst and hunger centers tell you that you are dehydrated and hungry. You decide cold water and chicken wings will satisfy such desires. Specify the movements, muscles, bones and joints involved in opening your mouth and chewing the wings. Explain any and all movements individually across each joint involved specifying the actions involved (i.e. flexion, extension, etc.), the muscles causing such actions, the bones being pulled on by said muscles, the types of joints involved.

You need to step up on a step to reach an object on a high shelf over your head. Your starting point should be anatomical position and your finishing point should be the position you are in once your hand has reached the object overhead. Specify the movements, muscles, bones, and joints involved in reaching up above your head to the object on the shelf. Explain any and all movements individually across each joint involved specifying the actions involved (i.e. flexion, extension, etc.), the muscles causing such actions, the bones being pulled on by said muscles, the types of joints involved, and how these movements collectively relate to the overall scenario/movements in this application.
