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 2 nd 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
