AP Biology Cat Dissection Lab Name_______________________ Instructions: Identify the following structures. Be sure to take good notes over their location, function, purpose, etc. The more detail you put into this lab packet, the more you will learn. Know the following planes, terms, and movements: Sagittal plane Coronal plane Transverse plane Superior/Inferior Ventral/Dorsal Anterior (cranial)/Posterior (caudal) Superficial/Deep Medial/Leteral Protraction/Retraction Proximal/Distal Elevation/Depression Eversion/Inversion Flexion/Extension/Hyperextension Adduction/Abduction Supination/Pronation Rotation Circumduction External Features: Write the necessary information in these areas. head neck trunk tail forelimb hind limb Locate the following on the cat and write the necessary information in the space. external nares pinnae nicitating membrane vibrissae axilla perineum The Skeleton Define the following : Axial skeleton Appendicular Skeleton Identify the following structures/bones. Skull/Cranium: Cranium, orbit, canine, mandible, zygomatic arch The vertebrae (cervical, thoracic, lumbar, sacral, caudal) Pectoral girdle (scapula, clavicle, sternum, ribs) Forelimbs (humerus, radius, ulna, carpal, metacarpal, phalanges) Hind limbs (femur, tibia, fibula, patella, tarsal, metatarsals) Muscular System Identify the following muscles on the cat. Be sure to write down any notes that you think are necessary. Note: Most anatomy classes will require you to know both the origin (site of attachment on part that does NOT move) and insertion (site of attachment on part that does move) for all the muscles. I simply want you to know the location (and subsequently the function) for each muscle. Head, Neck and Shoulders Muscles Sternohyoid Sternomastoid (lateral to the sternohyoid) Cleidomastoid Masseter Latissimus dorsi Triceps Brachii (long head and lateral head) Pectoral Muscles Pectoralis major Pectoralis minor Xiphihumeralis Clavotrapezius Acromiodeltoid Brachialis Acromiotrapezius Levator Scapulae Ventralis Spinodeltoid Spintotrapezius Epitrochlearis Brachioradialis Flexor Carpi Radialis Flexor Carpiularis Pronator Teres Pectoantibrachialis Biceps Brachii Trunk Muscles External Oblique Internal Oblique Transversus abdominis Gluteus Medius Gluteus Maximus Biceps Femoris Semitendinosus Caudo femoralis Tensor fascia latae Pelvic/Hind Muscles Rectus abdominis Sartorius Gracilis Adductor femoris Adductor Longus Gastrocnemeus Soleus Tibialis Anerior Iliopsoas Pectineus Rectus Femoris Vastus Lateralis Vastus Medialis Semimembranosous Identify the following structures on the cat. Be sure to write down any notes that you think are necessary. A description of the location and function is essential.
