Part of Unit: The Shoulder and Upper Arm
Lesson Plan Overview / Details
Students will be able to describe and identify the musculoskeletal anatomy of the shoulder using Anatomy in Clay by Zahourek systems (http://www.anatomyinclay.com/index.html). This is a lesson in which students will construct muscles out of terra cota clay and place them on a 2 ft. tall skeletal model. By the time this lesson will be delivered, I would have already introduced basic concepts and terminology using the Anatomy in Clay method in the Human Anatomy and Terminology unit located in this model. Students also take notes which include the Origin, Insertion and Action of the muslce in their interactive notebooks as described in the Introduction to Human Anatomy and Terminology in this model. Upon introducing a new body part we begin with a short video clip and then proceed to the muscle building followed by closing activity.

Activities in this Lesson
- Arthroscopic Shoulder Surgery - Hooks / Set
At the beginning of class I would have already set up the LCD projector and PC necessary to show the video clip of an arthroscopic shoulder surgery being performed. Before starting the video I also state the the clip is graphic and should they feel uneasy about it they may choose to turn away but must still remain quiet. Following the clip, I discuss with them that surgeons are like mechanics to cars or like carpenters to homes. They fix, attach, detach, rewire the human body. But just like those other professionals, they need to know the structure and function of what they are working on before they go in and start sawing, drilling and moving things around. Also, that surgery is trauma taking place in a controlled environment. The clip is in a WMV format, but I have included the link to the source from Youtube ( http://www.youtube.com/watch?v=RViGlehPpRg )
- Shoulder muscle building - Lab / Shop
All of my presentations are delivered using a Smartboard along with its Notebook software. I will include the accompanying files in Notebook format and also in PDF format. This lesson should take no more than a 90 minute block period. By the time we get to the shoulder, students would have covered the lower extremities and torso. Becasue of this, they already know the set up procedures for Anatomy in Clay lessons such as this. I also notify them that our muscular system is arranged in layers and not to make bulky muscles. The numbering I have is the order in which I deliver the muscles, you may present them in any order you would like. Everything in italics is what I state to them and explain to them as follows:
Slide # 1 : This is the TERES MINOR. Its origin is at the lateral border of the scapula. The insertion is at the dorsal facet of the greater tuberosity of the humerus. It acts to laterally rotate the humerus.
Slides # 2-4 : These are additional photos to show this muscle from different views.
Slide # 5 : This is the INFRASPINATUS . The origin is the infraspinatus fossa of the scapula. The insertions are at the facet of the greater tuberosity just above the tendon of the TERES MINOR. This muscle acts to laterally rotate the humerus.
Slides # 6-9 : These are additional photos to show this muscle from different views.
Slide # 10 : This is the SUPRASPINATUS muscle. The origin is at the supraspinatus fossa and inserts at the superior facet of the greater tuberosity. It acts to abduct the shoulder.
Slides # 11-14 : These are additional photos to show this muscle from different views.
Slide # 15 : This the TERES MAJOR muscle. It originates at the inferior angle of the scapula and inserts at the medial edge of the bicipital groove. Because of that it acts to medially rotate, adduct and extend the shoulder.
Slide # 16-18 : These are additional photos to show this muscle from different views.
Slide # 19 : This is the DELTOID SPINALIS muscle. Its origin is at the superior edge of the lateral 2/3 of the spine of the scapula. It inserts at the deltoid tuberosity. It acts to extend, abduct and laterally rotate the shoulder.
Slides #20-22 : These are additional photos to show this muscle from different views.
Slide # 23 : This is the DELTOID ACROMIALIS muscle. The origin is at the lateral edge of the acromion process. Its insertion is also at the deltoid tuberosity. It acts to abduct the shoulder.
Slides #24-26 : These are additional photos to show this muscle from different views.
Slide # 27 : This is the DELTOID CLAVICULARIS muscle. The origin is at the lateral 2/3 of the clavicle. It inserts at the deltoid tuberosity along with the other deltoid muscles. It acts to abduct and horizontally adduct the shoulder.
Slides # 28-29 : These are additional photos to show this muscle from different views.
- Clean up and pair sharing - Closure
Students will begin to clean their work stations, double check their striations on their shoulder muscles and compare them to their partners and also share their thoughts about today's lesson.
- Assessment Types:
- Journals, Writing Samples,
Upon completion of this lesson, I will assess their participation and comprehension using two different methods. First I will do a notebook check to see if they have recorded the names, origin, insertion and actions of all muscles covered. As described in the introductory Anatomy in Clay lesson located in the Introduction to Human Anatomy and Terminology section in this model, students will keep an interactive notebook in which they will write all information on muscles covered and also any associated activities.
The second assessment is that I will assign a one page essay in which they have to describe how the shoulder muslces covered in this lesson interact and work together for the common goal of an overhead swinging/throwing motion. I give them the prompt, "Describe how the shoulder muscles all interact and work together to throw a ball or even swing at a volleyball." I give them three school days to complete this and either e-mail me the assignment or manually submit the completed work.
