Ilium Pubis Ischium The pelvis is made of three bones on Anterior view of Pelvis Pubic symphysis ileum ischium pubis Anterior view of Pelvis Ilium Pubis Sacroiliac joint Ischium Anterior Inferior Iliac Spine Anterior Superior Iliac Spine Acetabulum Iliac Crest Obturator Foramen Posterior Inferior Iliac Spine Posterior Superior Iliac Spine Symphysis pubis or Pubic symphysis Pubic arch Differences between male and female pelvis • Female lighter • Female thinner • Female has less obvious muscle attachment sites •Obturator foramina smaller & further apart • Acetabulum smaller & further apart Differences between male and female pelvis Pubic arch in female is more “U” shaped. Pubic arch in male is more “V” shaped Femur = strongest and largest bone in body Femur Anterior Posterior Femur Medial epicondyle Lateral epicondyle Tibia and fibula Knee Joint Tarsals, Metatarsals, and Foot Phalanges Note there are 7 tarsals in each ankle Calcaneous Talus Metatarsal # 1 Metatarsal # 4 Distal phalanx # 1 Middle phalanx # 4 Calcaneous is the heel bone that Achilles tendon is attached to. It is also the largest tarsal. Talus is the 2nd largest tarsal; note how the superior end articulates with the tibia and fibula MALE SKULL •Heavier and rougher •Forehead is usually sloping •Sinuses are larger •Cranium about 10% larger •Mandible is larger •Teeth are larger DIFFERENCES BETWEEN MALE & FEMALE SKELETON MALE = Sacrum is long with pronounced sacral curvature FEMALE = Sacrum broad, short less curvature MALE = Coccyx points anteriorly FEMALE = Coccyx points Inferiorly MALE = Bone weight is heavier FEMALE = Bone weight lighter MALE = Bone markings more prominent FEMALE = Bone markings less prominent The end
