Q
locomotor system: cursorial adaptations
A
- reduced pectoral skeleton
- more cranial/caudal movement
- clavicle absent/vestigial
- deep, narrow chest - elongation at proximal end of limb
- scapula lies lateral and vertical - elongation at distal end of limb
- long metacarpals, walk on toes or hooves (increased leg length)
14
Q
cursorial vertibrates
A
animals that run on the ground and are structurally modified to enhance speed or endurance
