3 important questions on Lecture Eleven : Muscle IV - Complex movements (Standing and Gait)
Explain the difference between Bipedalism and Quadrupedalism ?
Quadrupeds use all 4 limbs to walk. Therefore, they have a wider base of support but locomotion requires more energy.
Bipeds only use 2 limb to walk. Therefore, they have 2 free upper limbs for manipulation. They have a smaller base of support but locomotion is more energy efficient.

Explain What the line of Gravity is in out body ?
- Hip : Line of Gravity runs posterior to the hip. The hip is locked into extension - ligaments are tight and minimal energy is required.
- Knee : Line of gravity runs anterior to the knee. The knee is locked into extension - ligaments are tight and minimal energy is required.
- Ankle : Line of gravity runs anterior to the ankle. The ankle falls into dorsiflexion - plantarflexors contract as stabilisers to prevent us from falling over , which requires energy.
Explain How the Gait Cycle works ?
