Diagram of Cat Muscles

A Few Muscle Movements

Movement of Masseter 

Movement of Frontalis 

Updated List of Muscles

** The ones with the origin and insertion are the only ones we need to know the origin and insertion of

Muscles of Head and Neck

Muscle	Origin	Insertion	Function/Movement
Masseter	Zygomatic arch	Lateral surface of angle and ramus of mandible	Elevates Mandible
Frontalis			Wrinkles forehead and fixes galeal aponuerosis
Occipitalis			Retracts scalp
Temporalis			Elevates mandible when great pressure is not required

Zygomaticus

Zygomaticus Major: smiling Zygomaticus Minor: elevates upper lip

Muscles of the Torso/Front

Linea Alba			Compresses abdominal contents, rotates vertebral column
Pectoralis Major	Clavicle, sternum, ribs 1-6	Intertuburcular groove	Pulls arm anteriorly and across chest, rotates humerus, or adducts arm
Pectoralis Minor			Elevates rib and protracts scapula
Rectus Abdominus	Crest of pubis and pubic symphysis	Xiphoid Process of sternum and costal cartilages	Tenses Abdominal wall, compresses abdominal contents, and flexes vertebral column
External Oblique			Tenses Abdominal wall and compresses abdominal contents
Internal Oblique			Tenses Abdominal wall and compresses abdominal contents

Muscles of the Torso/Back

Trapezius	Occipital Bone and spines of cervical and thoracic vertebrae	Clavicle; Spine and acromion process of scapula	Rotates scapula and raises arm; raises scapula; pulls scapula medially or pulls scapula and shoulder downward
Latissimus Dorsi	Spines of sacral, lumbar, and lower thoracic vertebrae, iliac crest, and lower ribs	Intertubercular groove of humerus	Extends and adducts arm and rotates humerus inwardly, or pulls shoulder downward and posteriorly
Rhomboid Major			Raises and adducts scapula
Supraspinatus			Abducts arm

Muscles of the Arm

Deltoid	Acromion process, spine of scapula, and clavicle	Deltoid tuberosity of humerus	Abducts arm, extends or flexes humerus
Biceps brachii			Flexes forearm at elbow and rotates hand laterally
Brachioradialis			Flexes forearm at elbow
Triceps brachii			Extends forearm at elbow
Flexor carpi radialis			Flexes and abducts wrist
Palmaris Longus			Flexes wrist

Muscles of the Leg

Gluteus Maximus	Sacrum, coccyx, and posterior surface of ilium	Posterior surface of femur and fascia of thigh	Extends thigh
Sartorius			Flexes leg and thigh, abducts thigh, rotates thigh laterally, and rotates leg medially
Adductor longus	Pubic bone near pubic symphysis	Posterior surface of femur	Adducts, flexes, and rotates thigh laterally
Vastus Lateralis			Extends leg at knee
Biceps femoris			Flexes leg, extends thigh
Gastrocnemius			Plantar flexion of foot and flexion of leg at knee
Rectus Femoris			Extends leg at knee

Cat Dissection 1: External Anatomy                                      NAME_______________________PER_____

Read and follow all written and verbal instructions!

Instructions:

Ø  Use Introduction: Photo Manual and Dissection Guide of the Cat, & your A&P lab manual to answer the questions.

Ø  Obtain a cat and place it in a dissection tray.  Wear an apron and safety glasses ALWAYS!

Ø  Label the bag & box with a permanent marker: Your names, Class period, Lab Station #

Ø  For this lab, you will not cut anything! Make all external observations before we start cutting next time!

Ø  When finished, cover cat with light spray of Carosafe, wrap in towel, and seal inside bag.  Put cat in box. 

Ø  Cleaning duties:     Clean dissection tray, utensils  and lab station thoroughly.  Return apron and goggles.
