Lower Appendage - PowerPoint Presentation

Slide1

Lower AppendageSlide2

Femur

Femur

– largest, longest, strongest bone

- articulates with

acetabulum

(proximal) and tibia & patella (distal)

Region from the hip to the knee

Head

– large, smooth, ball-shaped; fits into

acetabulum

Greater & lesser

trochanter

– projections at proximal end; sites for muscle attachment

Lateral & medial

condyle

– two large surfaces on distal endSlide3

Femur

On posterior view, the

gluteal

tuberosity

and the

linea

aspera

both serve as

attachement

sites for the tendons of the thigh muscles.Slide4

Patella

Kneecap

Anchors the anterior thigh muscle to the tibia

Base

– broad, superior end

Apex

– pointed, inferior endSlide5

Fibula

Slender bone on lateral side

Head

– on proximal end

Lateral

malleolus

– projection at the distal end that articulates with the talus

- forms the bulge of the ankle (outer)Slide6

Tibia

Larger, weight bearing bone on medial side; articulates with the femur & fibula (proximal) and fibula & talus (distal)

Lateral & medial

condyles

– slightly concave region where the

condyles

of the femur fit

Tibial

tuberosity

– rough area below the

condyles

for attachment of ligaments associated with the knee

Anterior crest

– sharp ridge on anterior surface; forms the shin

Medial

malleolus

– forms the medial bulge of the ankle (inner)Slide7

Foot

Composed of the ankle, insteps and toes

Tarsals

– 7

Tarsus

– ankle; articulates with lateral

malleolus

of fibula and medial

malleolus

of tibia

Calcaneous

– heel bone

Navicular

Meidal

cuneiform, intermediate cuneiform, lateral cuneiform,

cuboid

Metatarsals

– 5

Phalanges

– 14

Hallux

– big toe
