Locomotion Flashcards
Learning outcomes
Movements and planes
The lower limb: regions, bones, joints, planes & movements
Pelvic girdle / pelvis
Movements at the ankle & foot
Plantar surface of the foot = ventral surface = sole of the foot.
: Dorsum of the foot = dorsal surface = top of foot.
Movements of the ankle and foot occur about two anatomical planes.
* Plantar-flexion (pointing foot downward) and dorsi-flexion (pulling foot upward) movements occur about the ankle
(talocrural) joint in the sagittal plane.
* Eversion (rolling sole of foot outward) and inversion (rolling sole of foot inward) movements occur about the
frontal plane. Note that inversion/eversion occur below the talocrural joint at the subtalar joint.
Musculoskeletal system
Anterior thigh muscles extend the knee joint/leg
Muscles of medial thigh compartment adduct the hip/thigh
Lateral thigh & some gluteal muscles abduct the hip/thigh
Muscles acting on the hip and thigh: rotators
Muscles in the lateral compartment evert and plantarflex the foot
Femoral-on-pelvic & pelvic-on-femoral movements
Pelvic-on-femoral hip movements: flexion & extension
