Study Notes
True and False Pelvis
- The pelvic brim separates the true pelvis from the false pelvis.
- The true pelvis contains the pelvic cavity and is involved in childbirth.
- The false pelvis supports the lower abdominal organs.
Pelvic Outlet
- The pelvic outlet is also known as the inferior pelvic girdle.
- The shape of the pelvic outlet varies based on individual anatomy.
Sexually Dimorphic Features of the Pelvis
- Female-like Pelvis: Wider pelvic inlet, broader subpubic angle, blunt ischial spine, shorter sacrum, wider pelvic cavity.
- Male-like Pelvis: Narrower pelvic inlet, narrower subpubic angle, pointed ischial spine, longer sacrum, narrower pelvic cavity.
Os Coxae
- The os coxae (hip bone) is formed by three bones: ilium, ischium, and pubis.
- The ilium forms the superior region of the os coxae and part of the acetabulum.
- The ischium forms the inferior part of the os coxae and helps form the superior margins of the acetabulum.
- The pubis fuses with the ilium and ischium to form the anterior portion of the os coxae.
Age Differences in the Ossa Coxae
- Changes in the auricular surface can indicate age.
- Younger individuals have a smoother auricular surface.
- Older individuals have a more granular auricular surface.
Bones of the Lower Limb
- The lower limb consists of the thigh, leg, and foot.
- The femur is the longest bone in the body.
- The patella (knee cap) is a small, disc-shaped bone that improves the leverage of the quadriceps muscle.
Tibia and Fibula
- The tibia is the weight-bearing bone of the leg.
- The fibula is a slender bone that runs parallel to the tibia.
- The interosseous membrane connects the tibia and fibula.
Tarsals, Metatarsals, and Phalanges
- The tarsals form the bones of the ankle and proximal foot.
- The metatarsals form the arched part of the foot.
- The phalanges form the toes.
Arches of the Foot
- The three arches of the foot are the medial longitudinal, lateral longitudinal, and transverse arches.
- The arches support the weight of the body and prevent the blood vessels and nerves from being pinched when standing.
Pathologies of the Foot
- Bunion: Localized swelling at the first metatarsophalangeal joint, caused by improper footwear.
- Pes Cavus: High arch characterized by excessively high longitudinal arches.
- Talipes Equinovarus: Congenital clubfoot, where the foot is deformed and the heel turns inward.
