This laboratory exercise allows you to determine which back muscles produce movements of the vertebral column. Have your lab partner demonstrate the requested motion or see the action in Primal Pictures . List the muscles involved in the activity. To see a movie of the muscle action involved in the activity below, login to Primal Pictures (). Click on Functional Anatomy → Movies → Muscle function animations for export into PowerPoint → Head and neck or Trunk. Then select the appropriate animation for the requested activity below. To confirm/determine which muscles are involved in the activity, click on Animations (instead of Movies). Choose the appropriate body region (e.g., Head and neck) and then select the desired animation (e.g., Flexion/extension of the cervical spine). Once the animation appears, rotate it so that the posterior side is visible (click arrow ►in box), click the Play arrow ►in circle to view the action and hover the mouse over the muscle or structure of interest to identify it.

Part A. This laboratory exercise helps you identify the muscles visible in the back by viewing photos of prosections (dissected cadaver). At the lab bench are images of prosected cadavers showing some of the muscles and structures of the back. Be able to identify the muscles of the back in these photos. Images are from Primal Pictures (3D Atlas): Muscles of the vertebral column: ? embeddedcode=38ECAF Superficial muscles of the vertebral column: ? embeddedcode=F3ABC3 Suboccipital region of the neck: ? embeddedcode=02E8B0 Part B. This part of the laboratory exercise will help you become familiar with attachments and actions of the back muscles. For this exercise, work with student members of your laboratory table as a group. You may refer to the prosected images on the lab bench or Pre-lab images (Pre-Lab Exercise 4.8) to aid in your presentation to your group members.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
