Human Muscle Organ Study and Laboratory Dissection of the Mink

General Objectives

Lecture and Laboratory Activities

Muscles of the human body will be studied, in large part, by intensive coloring and study of the human anatomy coloring book. The specific plates to be colored include any plate that has any of the assigned muscles that are indicated in the Table below. You must determine this plate by plate for all muscle plates in your human anatomy coloring book. We will do a lecture overview of these plates during class time.

The second major component of your study of the muscle organs of the muscular system will come from laboratory dissections of commercially-raised ranch mink. Perform dissections as instructed in laboratory. The lab book (Walker) will be provided for your use in groups of three to four people, and one volume of the guide will be placed in the MSC Library for your out-of-class study time allotted: three laboratory sessions plus out-of-class time specific muscles to be located are marked indicated on a sheet in the laboratory (LS 106). Students planning to apply to the MSC physical therapy assistant program should be aware that the muscles covered in this program have been developed with input from Dr. Gary Robinson, Director of the Physical Therapy Assistant Program at MSC. He strongly encourages his pre-PTA majors to know the muscle information in our course by heart even after the completion of the course (not just for our anatomy and physiology exams!).

Where there are slight differences in names of a mink muscle with its human counterpart, you may use human muscle names. In such cases, I will accept either name on the laboratory practical exam covering the mink muscles. Focus on the following: name of muscle, origin and insertion of muscle, function of muscle.

Table MS 1- List of Required Muscle Organs and Associated Structures for Human Anatomy and Physiology II (Sections Taught by Bruce G. Stewart). 

IMPORTANT NOTES:

All muscles and structures listed below are required to be colored on any plates assigned in class from the Human Anatomy Coloring Book.

Muscles preceded by an '*' are those that will be included in the muscle dissections of the mink and the student must be able to expose and identify each with the help of the dissection guide.

Muscles preceded by an '**' will be those mink muscles that are required for the laboratory practical exam, and the student must be able to recognize them from memory.

Reminder about Textbook Study

As with other topics, your textbook has excellent presentations of the materials on the muscular system. While you should focus on the specific material in the Notes on the Web, you should always use your textbook as a resource for illustrations and for understanding content that your notes cover.

As with all materials throughout the semester, you will have opportunities to ask questions or ask that any relevant material from your assignments be discussed in class.
