The Muscular System

Before you come to lab:

  1. Take the list of skeletal muscles (see Lab Exam 2 Review Sheet) and use the two figures provided to learn the general locations of the muscles in the body. I suggest you learn them in the following categories:
    • head/neck
    • torso (front)
    • torso (back)
    • arm
    • forearm
    • thigh
    • leg

During the lab period (preferably complete in order):

  1. Working with muscle models:
    • The hardest part of Lab Exam 2 is learning the skeletal muscles.
      • On this exam, even more so than the first, studying is rewarded and laziness is punished.
    • This week is your opportunity to get experience using the lab models.
      • These are the models that I’ll use for the lab exam.
    • We have six appendage models (three arms and three legs) and two torso models.
      • The keys for the appendage models can be found here.
      • The keys for the torsos are in the drawers of the torso carts.
      • Please do NOT disassemble the appendage models. All of the muscles that you need to know are on the outside surface.
    • Using the models and the keys provided, make your own keys to the models.
      • Only concentrate on the muscles for which you are responsible!
      • Here are sheets for you to use to make your own keys.
        • These are for your use only! Don’t pass them in!
    • You are responsible for learning the major action of each muscle.
      • This information can be found in Exercise 15 in the Lab Manual (pp. 197-226).
      • Pick the one action that makes sense to you.
      • I test the actions by multiple choice, so you’ll have a decent shot if you’re at least familiar with what each muscle does.
    • Two more Lab Exam hints:
      1. I always pick the largest, most prominent muscles for the exam.
      2. You’ll be tested on the head/neck muscles by figure only!

Additional resources:

  1. This file contains all of the muscle figures from the textbook without their labels.
    • This may be helpful, but is no substitute for using the models.
  2. This document discusses how many of the skeletal muscles received their names. For those of you comfortable with Latinized words, this may be helpful.
  3. Check out this website.
    • This site has photos of models (including our appendage models).
    • If you move your mouse over the different numbers, you’ll see the name of the muscle appear.
  4. Lastly, the ARC also has muscle models available for you to use.
