2 17a A&P:! Skeletal System - Joint Actions and Articulations! Class Outline" 5 minutes" "Attendance, Breath of Arrival, and Reminders " 10 minutes "Lecture:" 25 minutes "Lecture:" 15 minutes "Active study skills:" 60 minutes "Total"

3 17a A&P:! Skeletal System - Joint Actions and Articulations! Class Reminders"

4 Classroom Rules" Punctuality - everybody s time is precious"! Be ready to learn at the start of class; we ll have you out of here on time"! Tardiness: arriving late, returning late after breaks, leaving during class, leaving early" The following are not allowed:!! Bare feet"! Side talking"! Lying down"! Inappropriate clothing"! Food or drink except water"! Phones that are visible in the classroom, bathrooms, or internship" You will receive one verbal warning, then you ll have to leave the room.!

5 Frontalis and Occipitalis! Trail Guide, Page 258" Lateral View" Frontalis and Occipitalis together form the occipitofrontalis. " They are responsible for raising the forehead into an expression of surprise. " Although they are superficial, their thin fibers cannot be isolated."
