Standard AP 2.9 Identify major skeletal muscles on a diagram of the human body’s and describe the movements associated with each of them.

Directions: Scientists – pick up papers from the lab materials table for your lab team. Glue in the pictures as you take notes in your science notebook.

Glue this picture on the next blank page of your notebook. Highlight the names of muscles you learned last year. Names of Major Muscles

Naming of Skeletal Muscles Slide 6.36a Copyright © 2003 Pearson Education, Inc. publishing as Benjamin Cummings  We have over 650 skeletal muscles.  How are they named?  Where do the names come from?

Naming of Skeletal Muscles Slide 6.36a Copyright © 2003 Pearson Education, Inc. publishing as Benjamin Cummings  Direction of muscle fibers  Example: rectus (straight)  Relative size of the muscle  Example: maximus (largest)

Naming of Skeletal Muscles Slide 6.36b Copyright © 2003 Pearson Education, Inc. publishing as Benjamin Cummings  Location of the muscle  Example: many muscles are named for bones (e.g., temporalis)  Number of origins  Example: triceps (three heads)

Naming of Skeletal Muscles Slide 6.37 Copyright © 2003 Pearson Education, Inc. publishing as Benjamin Cummings  Location of the muscles origin and insertion  Example: sterno (on the sternum)  Shape of the muscle  Example: deltoid (triangular)  Action of the muscle  Example: flexor and extensor (flexes or extends a bone)

Head and Neck Muscles Slide 6.38 Copyright © 2003 Pearson Education, Inc. publishing as Benjamin Cummings Figure 6.14

Trunk Muscles Slide 6.39 Copyright © 2003 Pearson Education, Inc. publishing as Benjamin Cummings Figure 6.15

Deep Trunk and Arm Muscles Slide 6.40 Copyright © 2003 Pearson Education, Inc. publishing as Benjamin Cummings Figure 6.16

Muscles of the Pelvis, Hip, and Thigh Slide 6.41 Copyright © 2003 Pearson Education, Inc. publishing as Benjamin Cummings Figure 6.18c

Muscles of the Lower Leg Slide 6.42 Copyright © 2003 Pearson Education, Inc. publishing as Benjamin Cummings Figure 6.19

Superficial Muscles: Anterior Slide 6.43 Copyright © 2003 Pearson Education, Inc. publishing as Benjamin Cummings Figure 6.20

Superficial Muscles: Posterior Slide 6.44 Copyright © 2003 Pearson Education, Inc. publishing as Benjamin Cummings Figure 6.21

Notes: Body Movements Review this diagram with your lab group! Remember…today’s exit slip will require you to DRAW limbs (arms and legs) in specific muscle movements!

Notes: Body Movements Slide 6.30a Copyright © 2003 Pearson Education, Inc. publishing as Benjamin Cummings  Movement is achieved by muscle moving to an attached bone. Figure 6.12

Notes: Body Movements Slide 6.30b Copyright © 2003 Pearson Education, Inc. publishing as Benjamin Cummings  Muscles are attached to at least two points  Origin – (start) attachment to a fixed bone  Insertion – (end) attachment to a moveable bone Figure 6.12

Notes: Body Movements Slide 6.32 Copyright © 2003 Pearson Education, Inc. publishing as Benjamin Cummings  Flexion  Decreases angle of joint, brings two bones closer together  Bending elbow  Extension  Opposite of flexion, increase angle of a joint, two bones moving further apart  Straightening elbow

Notes: Body Movements Slide 6.32 Copyright © 2003 Pearson Education, Inc. publishing as Benjamin Cummings  Rotation  Moving a bone around it’s x or y-axis  Turning head  Abduction (AB- duction)  Moving a bone AWAY from midline  Adduction (think…ADD to body)  Moving a bone CLOSER to midline

Checking for Understanding Analysts - quiz your lab group! 1.Show me FLEXION at the shoulder joint 2.Show me EXTENSION at the knee joint 3.Show me ROTATION at the cervical spine 4.Show me ABDUCTION at the hip joint 5.Show me ADDUCTION at the hip joint

Checking for Understanding Write in your notebook! 1.What is the difference between the origin of a muscle and the insertion point? Write in COMPLETE SENTENCES in your notebook. Be prepared to share out!

Reading Directions: On your own…Read and annotate the text (double sided). See the blue annotation marks examples in your yellow folder.

Group Work Directions: Work with your lab group to complete the classwork packet. This packet also includes information on the anatomy of skeletal muscle. See page 195 – 203 in your textbook and use your ipad. You will have 20 minutes (double sided). Be sure to check your yellow folder for ANSWER KEYS! Remember…Be prepared to LABEL major skeletal muscles on a diagram!
