Lab 17: Upper Extremity Muscle Lab Exercises Before completing these lab exercises, be sure to review the “ Lab 17: Upper Extremity Muscles Background, Videos and Practice Activities ” in Canvas. The following exercise is intended to be completed at the same time or after you have viewed the models, photos, videos and the list of muscle names and actions. You may wish to make copies of the following pages before you start in order to be able to fill in the tables a second time. For most people, writing information down is by far the most effective way to facilitate learning it. Another very productive learning tool is to take the information you are studying and to reorganize it into a form of your own, an organization that is at least a little different than the one used when the information was presented. See Canvas for worksheets that can help you do that, plus other study tools. Resources Resources to help you complete the following activities: ● Skeletal Muscle Identification Guide : Upper Extremity Muscle Section ● Your textbook ○ Recommended Marieb and Hoehn Text: ■ Chapter 10, including Table 10.10, 10.11, and 10.12 ○ OpenStax A and P: ■ Chapter 11, Section 11.5 , including Figures 11.25, 11.26 and 11.27 ● Resources linked in the “ Lab 16: Upper Extremity Muscles Background, Videos and Practice Activities ” page in Canvas. ○ Interactive Upper Extremity Images : Hover over photos to learn about each muscle ○ Upper Extremity Muscles Video ○ StudyMate Flashcards for Upper Extremity (also includes some shoulder muscles from Lab 18) Muscles Covered in this Lab Biceps brachii Brachialis Triceps brachii Brachioradialis Pronator teres Flexor carpi radialis Flexor carpi ulnaris Extensor carpi ulnaris Extensor digitorum Extensor carpi radialis longus Muscle Labeling Exercises (Linked) Use the “Upper Extremity Muscle Labeling Exercises” in Canvas to practice your muscle identification. The Upper Extremity Muscle Labeling Exercises will be submitted with your Lab 17 UPLOAD assignment, and you will need to input some of your answers in the Lab 17: Lab Exercise Submission. Notice all blanks are numbered for those who may not want to print the activity, and do not have the ability to complete the worksheet electronically. Simply use any sheet of paper to write your answers by writing down the numbers and corresponding names, or use the table at the end of this document.

Upper Extremity Muscle Location Review Table ● In order to review the location of the muscles covered in this lab, complete the following table. The answers can be found in the resources section above. ● As you write the specific origin and insertion landmark names, include and underline the bone name(s) in each box. For the quiz and practical exam, you will need to know the specific landmark for the origin and insertion, not just the bone. ● For the “Location on body” column, please fill in whether the majority of the muscle is on the anterior, posterior, medial or lateral part of the limb. ● Gray boxes indicate that the origin or insertion does not need to be memorized, but knowing the general origin and insertion of a muscle can help you find the muscle and should be filled in on the chart. Muscle Origin: Landmark (if specified) and Bone Name Joint(s) Crossed Insertion: Landmark (if specified) and Bone Name Location on limb (see above) Biceps brachii Coracoid process and supraglenoid tubercle of scapula Shoulder (glenohumeral), elbow (humeroulnar) Radial tuberosity of radius Anterior Brachialis Humerus Elbow Coronoid process of ulna Anterior Triceps brachii Infraglenoid tubercle of scapula Proximal third of humerus Distal half of humerus Shoulder, elbow Olecranon process of ulna Posterior Brachioradialis Proximal to the capitulum of humerus Elbow Proximal to the styloid process of the radius Anterior Pronator teres Medial epicondyle of humerus Coronoid process of ulna Elbow Mid-lateral surface of radius Anterior Flexor carpi radialis Medial epicondyle of humerus Wrist, elbow Metacarpals 2 & 3 Posterior Flexor carpi ulnaris Medial epicondyle of humerus Wrist, elbow Medial carpals Metacarpal 5 Lateral, posterior Extensor carpi ulnaris Lateral epicondyle of humerus Wrist, elbow Metacarpal 5 Lateral, anterior Extensor digitorum Lateral epicondyle of humerus Wrist, elbow Middle and distal phalanges of each finger Posterior Extensor carpi radialis longus Lateral epicondyle of humerus Wrist, elbow Metacarpal 2 Lateral BIO201 @ MCC Lab 17: Upper Extremity Muscle Lab Exercises, Page 2

Identifying Muscles Causing Actions The following exercise encourages you to consider the muscles in working groups that perform similar actions. For each action, the number of muscles producing the action is listed in parentheses. Action Name(s) of muscle producing action covered in this lab exercise Flexes humerus or arm (1) Biceps brachii Extends humerus or arm (1) Triceps brachii Flexes forearm (5) Brachioradialis, Pronator teres, Flexor carpi radialis, Brachialis, Biceps brachii Extends forearm (1) Triceps brachii Pronates forearm (1) Pronator teres Supinates forearm (1) Biceps brachii Flexes hand (2) Flexor carpi ulnaris, Flexor carpi radialis Extends hand (2) Extensor carpi ulnaris, Extensor carpi radialis longus Abducts hand (2) Flexor carpi radialis, Extensor carpi radialis longus Adducts hand (2) Extensor carpi ulnaris, Flexor carpi ulnaris Extends phalanges (1) Extensor digitorum Muscle Antagonists 1. List at least one muscle covered in the lab materials for this class that acts as an antagonist to the following muscles. Use the lab materials to determine the antagonist based on the opposing actions of the muscles as listed in the lab materials. a. Biceps brachii Triceps brachii b. Flexor carpi radialis Flexor carpi ulnaris, Extensor carpi ulnaris, Extensor carpi radialis longus BIO201 @ MCC Lab 17: Upper Extremity Muscle Lab Exercises, Page 3

Remember to also complete and submit the Labeling Exercise: Upper Extremity Muscles (See Canvas) with your lab upload. If you do not have a printer, use the numbers to create a list of the indicated bones and landmarks and include the list on the next page or a separate page. Labeling Exercises Table for Upper Extremity Muscles You are encouraged to print or use an electronic format to complete the Labeling Exercises, but you may also use the table below to fill in the bone names if you do not have a printer or prefer not to print the lab. If you fill out the boxes on the Labeling Exercise, you do NOT need to complete this section. If you are printing this lab and printing the Labeling Exercise, you do not need to include this page.
