Another type of functional complex is the motor-movement
complex: how creatures move from place to place. We can infer the
mode of locomotion (how creatures move) by looking at their upper
limb bones: humerus (upper arm), ulna and radius (lower arm).
Station 2: Examine the humoral head of the following animals to
determine how stable/rigid or how flexible/mobile the shoulder joint
is. Terrestrial species generally have stable joints with a humerus
that has an oval-shapped head and large to moderate tuberosities.
Arboreal species generally have flexible, mobile joints with round
humeral heads that have low tuberosities.
