The Dinosaur Skeleton Flashcards
Compression
Pushing together an example is gravity
Vertebrate skeleton
A compromised structure because of the need for support versus the need for movement
Tension
Pulling apart an example is hanging
Shear
Causes layers or parts to slide up on each other in opposite directions
Bone
Composite composed of collagen and hydroxyapatite it’s best at resisting compression
Joints
Determine limits of movement
Cartilage
Light flexible covers joints
Muscles
Attached to the bone
Tendons
Transfer muscle to a small attachment point
Ligament
Attach bones to bones strap like
Sclerotic bones
Ring in eyeball, preserves shape under pressure
Dermal scutes
Bones floating in skin
Holes in the skull
Nares, mandibular fenestra, antorbital fenestra, orbit, supratemporal fenestra, infratemporal fenestra
Types of vertebra
Cervical, dorsal, sacrum (fused), caudal
Parts of a vertebra
Neural spine, transverse processes, neural canal, centrum, haemal arch (chevron)
