Codex On The Flight of Birds• 1505• Describes the nature of
bird flight• First to articulate that
flying is not a flapping motion but rather, it is a swimming motion
• Also suggested that center of gravity is not equal to center of pressure
Gallus
• First chickens noted in India in 3200 BC
• 175 Different Varieties/Subspecies
• Longest sustained flight = 13 seconds
Key Observational Points• Anatogonistic muscle
pairs of upper and lower wing
• Points of origin and insertion for major muscle groups
• Diversity and application of various connective tissues (cartilage, tendons, ligaments, etc.)
• Form and function of integumentary system
• Homology to human appendicular anatomy
Procedure
• 1) Skin the wing, cutting below the fat and above the fascia (translucent muscle covering/mesentary)
• 2) Articulate the paired flexors of the upper and lower wing manually and note the direction of movement in the wing
• 3) Articulate the paired extensors of the upper and lower wing manually and note the direction of movement in the wing
Procedure 2
• 4) Identify the tendons attached to each flexor or extensor and identify as a point of origin or insertion
• 5) Sever a flexor muscle and note the effect
• 6) Sever an extensor and note the effect• 7) Observe a hinge joint and note the
ligaments and articular cartilage
