MUSCLE LIST 2011
DIRECTIONS: ENJOY THIS DISSECTION
REMEMBER GLOVES!!!! CLEAN YOUR STATION!!!!!!
1. BEFORE you attempt to locate these muscles on the cat you must:
a) find the muscle on the human diagram, draw a line to it, and label it using a RED INK PEN.
Refer to the LAB BOOK at the lab table, your textbook, class reference books, and lab packet
b) Use a BLUE INK PEN to write the muscle’s ACTION next to the name.
c) color the human muscle the color indicated on the list
d) READ in the cat muscle packet or coloring or book for the information given about this muscle’s location and action
e) Make a flashcard of each muscle (name or picture) with action, insertion and origin
f) ) NOW YOU ARE READY TO LOCATE THE MUSCLE ON THE CAT
2. This is YOUR DISSECTION, not mine, therefore, here are the RULES:
a) If you have done all you can to locate a particular muscle
DOING ALL YOU CAN INCLUDES:
*LOOKED IT UP IN THE CAT PHOTOMANUAL,
* READ THE DESCRIPTION IN THE CAT MUSCLE PACKET,
*KNOW WHERE IT IS ON THE HUMAN AND WHAT IT DOES,
*CHECKED THE DEMO CATS FOR THE MUSCLE,
* ISOLATED THE MUSCLE and have your probe underneath it ), then you can ask for clarification…
b) BUT if I have to find the muscle for you, you’ll lose 1 point on the dissection grade, you’ll learn much more if you are independent.
c) Muscles are all to be tied with White Yarn. A colored piece of yarn will then be tied to the white for color coding. See the Demo Cats
d) PARTICPATION IS MANDATORY! Absent? THEN DO YOUR OWN DISSECTION AT LUNCH. Notecards will be keeping track for you.

58. External intercostals - aqua ( pulls ribs toward one another to elevate rib cage for inspiration. Synergist to diaphragm muscle. ) USE WINDOWING TECHNIQUE (*To locate in the cat lift the xiphihumeralis & external oblique on the opposite side of where you have tied them…reflect both…look between the ribs.
59. Internal intercostals- gray ( pulls ribs together and depresses rib cage to aid in expiration. Antagonist to external intercostals) USE WINDOWING TECHNIQUE (* To locate, lift a section of external intercostals, reflect them and grab a section to tie.
***not to be tied, but diaphragm muscle is the prime mover of inspiration.
Muscles of the Back
