LAB: CAT DISSECTION JOURNAL REQUIREMENTS

1. Journal should resemble a scrap book.

2. Have a Creative Title Page with your Cat≠s name.  On the second page be sure to include all the group members≠ names and what period you are in. 

3. The journal must be bound in some way.

4. Everyday you need to include what was doneÓbe specific.  Here are two examples for explaining how you dislocated the mandible: 

Bad Example: ≥Today we dislocated the jaw.

Good Example: ≥Today we cut through the masseter and digastric muscles, and removed the connective tissue surrounding the mandible.  After prying and loosening the mandible with a probe, we were eventually able to dislocate it.

*Do NOT copy the lab manual as that will be deemed as plagiarism and you will earn a 0

5. Each day list each member and his/her role.  Include if he/she is absent.  Make this very easy for me to identify.

6. Include pictures in your scrapbook.  I prefer pictures of your lab group dissecting, but you may include pictures from the internet that show the regions you dissected instead.

7. After your final entry of your daily dissection activities, list all the muscles≠ origin, insertion, and action for the list below:

            Facial:  Temporalis, Masseter, Frontalis, Orbicularis oculi, Zygomaticus, Orbicularis oris

            Neck:  Platysma, Sternohyoid, Sternocleidomastoid, Occipitalis, Trapezius

            Shoulder:  Trapezius, Deltoid,

      Rotator Cuff (Subscapularis, Supraspinatus, Infraspinatus, Teres major)

            Back: Latissimus dorsi

            Thorax:  Pectoralis major, Pectoralis minor, Serratus anterior, Intercostals, Diaphragm

            Hip:  Gluteus medius, Gluteus maximus

            Arm:  Triceps brachii, Biceps brachii, Brachialis

            Forearm:  Pronator teres, Brachioradialis, Flexor carpi radialis, Palmaris longus,

     Extensor carpi radialis, Extensor digitorum

            Abdomen:  Rectus abdominis, External oblique, Internal oblique, Transversus abdominis
