Seeley’s Essentials of Anatomy and Physiology
1. Define the principles of “origin” and “insertion”. Define each term and their function. (10 points)
2. Choose one of the following bones: femur, humerus, scapula, or tibia. Review the diagrams of bones in Chapter 6 and describe in 5-7 sentences the anatomical features of the bone you have chosen. (10 points)
3. Then, go to Chapter 7 and find the bone you chose in the tables on pages 177-185. These tables show which bones each muscle is attached to. Look for the bone you chose in the columns marked origin and insertion. There you should find the muscles that are attached to your particular bone. Please discuss the bone that you chose in relation to its matching muscles. Include a description of the origin and insertion points, along with the actions the muscles attached to this bone perform. Does this bone or the muscles attached to it interact with any other bones or muscles? (20 points)
When composing your 3A assignment listing the muscles pertaining to your bone, it might be easier to list them with bullet points, or use a table:
1st Muscle: origin site, insertion site, performs what action/movement on what body part
2nd Muscle: origin site, insertion site, performs what action/movement on what body part
The information in the tables are truncated/shortened in order to fit, so make sure you explain what some of the particular movements would be. For example, “Everts and plantar foot” should be written something like, “Everts or moves the foot outwards, and plantar flexes the foot downwards” Don’t’ just copy from the text; I need to know you understand the information. And be sure to go through all of the tables to find your bone and its corresponding muscles; that bone may be in more than one table.
