Recommended time schedule: Week 6 – Review a microscope slide of skeletal muscle tissue.   Then, dissect mink at least through infraspinatus on the list that follows; Week 7 – Try to finish mink muscles so that you can review the following week; Week 8 – Review mink muscles, human model muscles and review the muscle twitch.

Mink Dissection: There are enough mink so that every 3-4 people
may have one mink. The mink may not leave the laboratory room! Dissect as described by your instructor and with the help of the dissection photographs provided.  Put your mink away as described by your instructor when your dissection is complete. Clean your working area thoroughly.

Why do we dissect? With all of the great technology tools, like 3-d imaging, why do we dissect in lab?  The physical act of dissection is an extremely effective learning tool in contrast with “virtual dissections” available in computer programs.   Dissection is the best way to provide a tactile sense of body tissues.  In fact the word “anatomy” comes from Greek “to dissect” or “cut up.”  Currently, even with virtual reality headsets, nothing can reproduce the learning of anatomy through your actual tactile sense (in addition to other senses).  This experience will help you touch, visualize, and separate tissues in order to learn them.  Most A&P students are pursuing careers in healthcare.  At some point, this experience in dissection will help in the diagnosis and/or treatment of your patients.   For example, it is how we know that muscle won’t hold stitches well but tendons will.  Or, if you are a first responder at a car wreck at night, you may only have your sense of touch to immediately decide what to do. 

Why do we dissect mink? Although many students are excited about the dissections, there are still several questions that arise when it comes to the animals. There are several reasons why this choice of dissection animal has been made.  We do not have the space, money, nor supply of human cadavers to dissect.  MSU Denver offers an upper division anatomy course to dissect a human cadaver, called Advanced Human Cadaver Anatomy.  We dissect mink in A&P because once you understand that a mink’s anatomical position is on all four feet, their anatomy is very similar to that of humans.  After you learn the structures on the mink, we offer cadaver “tours” towards the end of the semester, to make that transition to the human anatomy.  The question of the ethics of using animals for medical science dissection and learning can and should be raised.  The mink are farm-raised for their fur.  Following euthanasia, their bodies are simply discarded, as they are of no use to the farmer.  We purchase the bodies, so that students may at least benefit from studying their anatomy. 

You are responsible for the following mink structures:

Neck, Chest and Abdominal Muscles: Mylohyoid, Digastric, Masseter, Pectoralis major, Pectoralis minor, Rectus abdominis, Linea alba, External oblique, Internal oblique, Transversus abdominis.

Note:  It is an online test through Connect.  The link is near the bottom of your course homepage on Connect.   It is mink muscles, human muscles, skeletal muscle histology and the 3 parts to a muscle twitch as describe in the lab objectives above. It is timed at 60 minutes (double the amount of time that it should take to complete) but you write the answers on your own paper or document and submit the answers as an attachment to an email.  It is due by 11:59 pm March 21.  The submission to me is not timed, but the test will only be open for 60 minutes.  There are 25 questions worth 2 points each.  Here is a quizlet made by your classmate Dan, that may help in test preparation:

Here is a quizlet made by your TA, Jenna:


Use this time to complete the review sheet assignment which consists of completing 1. the Review Sheet in your Marieb Laboratory Manual “Exercise 13 Review Sheet: Gross Anatomy of the Muscular System” PLUS 2. the review sheet on Skeletal Muscle Physiology found here. (Skeletal Muscle Review Sheet)  You may do these review sheets at home. The two review exercises are due by 11:59 pm April 10.   Scan/photograph them and submit them electronically attached to an email.  You will lose 5 points per day that they are submitted late.  10 points are possible for complete and accurate answers of each review exercise for a total of 20 points.  Here is a link to the Exercise 13 in case you don’t have the lab manual:


Exercise 15: Observe a microscope slide of a typical neuron.  See Figure 15.2.


Exercise 17: Refer to Exercise 17 and identify the following:

Meninges: Dura mater, arachnoid, pia mater.

Dorsal Structures: Longitudinal fissure, convolutions, cerebrum, cerebral hemispheres, cerebellum, corpora quadrigemina (superior and inferior colliculi).

(Note, cranial nerves VII, VIII, IX and X are often difficult to find or missing on some of the brains and are therefore skipped on structures you must know.)

Internal Structures: Corpus callosum, lateral ventricle, fornix, third ventricle, thalamus, hypothalamus, pineal body, midbrain, cerebral aqueduct, fourth ventricle, cerebral peduncles, pons, medulla oblongata, and cerebellum.

Additionally, check out cadaver nerves on Connect through Cadaver Dissection Tool.  Choose Nervous System and then type in name of brain structure in search bar.
