1 Pelvis Femur Tibia,Fibula Tarsals, Metatarsals Phalanges
Lower Extrmities Pelvis Femur Tibia,Fibula Tarsals, Metatarsals Phalanges

2 Pelvis(Coxal Bone) Iliac Crest: upper, curving boundary of ilium
Ilium: Upper flaring portion Ischium: Lower, posterior portion Pubic bone (pubis): Medial, anterior section Acetabulum: Hip socket; formed by union of ilium, ischium, and pubis.

3 Pelvis cont. Iliac spines:
A. Anterior superior: Prominent projection at anterior end of iliac crest; can be flelt externally as “point” of hip. B. Anterior inferior: Less prominent projection short distance below anterior superior spine.

4 Pelvis cont. C. Posterior superior: At posterior end of iliac crest.
D. Posterior inferior: Just below posterior superior spine. Greater Sciatic Notch: Large notch on posterior surface of ilium just below posterior inferior spine.

5 Pelvis cont. Spine of Ischium: pointed projection just above tuberosity. Obtuator foramen: large hole in anterior surface of os coxa; formed by pubis and ischium; largest foramen in body. Ischial Tuberosity: Large rough, quadrilaterial process forming inferior part of ischium.

6 Pelvis cont. Ramus of Ischium: Lower part of Ischium
Superior Ramus of Pubis: Part of pubis lying between symphysis and acetabulum; forms upper part of obturator foramen. Inferior Ramus of Pubis: Part extending dowwn from symphysis unites with ischium. Pubis: lower part of pelvis.

7 Pelvis cont. Pubic tubercle: Rounded process at end of crest
Pubic crest: Upper margin of superior ramus.

8 Femur Thigh bone; largest bone in body
Head: rounded upper end of bone; fits into acetabulum. Neck: Constricted portion just below head. Greater Trochanter: Protuberance located inferiorly and laterally to head. Lesser Trochanter: Small protuberance located inferiorly and medially to greater.

9 Femur cont. Intertorchanteric line: Line extending between greater and lesser trochanter. Condyles: Large, rounded bulges at distal end of femur, one medial and one lateral. Epicondyles: Blunt projections from the sides of the condyles; one on the medial aspect and on the lateral aspect. Adductor tubercle: Small projection just above medial condyle; marks termination of medial supracondylar ridge.

10 Femur cont. Trochlea: Smooth depression between condyles on anterior surface; articulates with patella. Intercondyloid fossa: Deep depression between condyles on posterior surface; cruciate ligaments that help bind femur to tibia lodge in this notch.

11 Patella Kneecap; largest sesamoid bone of the body; embedded in tendon of quadriceps femoris muscle.

12 Tibia Shin bone Condyles: bulging prominences at proximal end of tibia; upper surfaces concave for articulation with femur. Intercondylar eminence: Upward projection on articular surface between condyles. Crest: Sharp ridge on anterior surface. Tibial tuberosity: Projection in midline on anterior surface.

13 Tibia cont. Medial malleolus: Rounded downward projection at distal end of tibia; forms prominence on medial surface of ankle.

14 Fibula Long, slender bone of lateral side of lower leg
Lateral malleolus: Rounded prominence at distal end of fibula; forms proninence on lateral surface of ankle. Head: Prominence on proximal end of Fibula; articulates with lateral surface of tibia. This is the non weight bearing bone of the lower leg.

15 Tarsals bones that form heel and proximal or posterior half of foot.
Calcaneus: heel bone Talus: Uppermost of tarsals; articulates with tibia and fibula; boxed in by medial and lateral malleolus. Navicular: articulates with the talus and cuneiforms I, II, & III

16 Tarsals cont. Cuneiforms: form arch of foot; Numbered I,II, & III; articulate with navicular and Metatarsals Cuboid: forms side of ankle; articulates with calcaneus and IV & V Metatarsals.

17 Metatarsals Long bones of the foot
Numbered like the metacarpals of the hand. I - big toe through V - little toe

18 Phalanges Miniature long bones of the toes; two in each great toe; three in other toes.
