---|---|
Ossa Coxa | The hip bone--large irregularly shaped bones that articulate with the sacrum to form the pelvis. Three fused bones form the coxa: the ilium, ischium, and the pubis |
Ilium | One of the three fused bones of the ossa coxa; it forms the upper half of the ossa coxa |
Iliac Crest | An attachment site for muscles moving the vertebral column and the legs |
Iliac Fossa | A large, smooth concave surface on the anterior side of the ilium |
Greater sciatic notch | A large space between the ischial spine and the posterior inferior iliac spine; serves as a route for the passage of nerves and blood vessels to the posterior side of the pelvic girdle |
Anterior superior iliac spine | Part of the iliac spine that is found by the front and more to the top of the ilium; serves as an attachment point for muscles |
Posterior superior iliac spine | Part of the iliac spine that is found in the back and more to the top of the ilium; serves as an attachment point for muscles |
Anterior inferior iliac spine | Part of the iliac spine that is found by the front and more to the bottom of the ilium; serves as an attachment point for muscles |
Posterior inferior iliac spine | Part of the iliac spine that is found by the back and more to the bottom of the ilium; serves as an attachment point for muscles |
Ischium | One of the three fused bones of the ossa coxa; it forms the lower and back region of the ossa coxa |
Ischial Tuberosity | An attachment site for ligaments holding the sacrum in place and for muscles that move the thigh and leg |
Ischial Spine | An attachment site for ligaments that hold the sacrum in place |
Pubis | One of the three fuse bones of the ossa coxa; it forms the lower and front region of the ossa coxa |
Pubic Symphysis | The anterior connection between the two coxae, made of cartilage |
Pubic Arch | Portion of the pelvis where the ischium and the pubic bones converge, below pubic symphysis; females have wider arches |
Superior Ramus | The higher of the two rami, where it forms the upper edge of the obturator foramen. |
Inferior Ramus | The lower of the two rami, where it passes down laterally and downward from medial end of superior ramus |
Obturator Foramen | Large opening created by the ischium and pubic bones that allow blood and nerves to pass |
Acetabulum | "Vinegar cup"--a depression in the coxa that holds the head of the femur but allows it to move. Forms the hip joint with head of the femur. |
Femur | The longest and strongest bone of the body, found in the thigh |
Head of the Femur | The ball-like proximal end of the femur inserts into the acetabulum of the coxa. |
Neck of the Femur | Flattened landmark of the femur, connecting the femoral head with the shaft |
Greater Trochanter | Larger attachment site for hip muscles moving the femur |
Lesser Trochanter | Smaller attachment site for him muscles moving the femur |
Medial Condyle of Femur | Middlemost bumps on the distal end of the femur that helps bear weight and move the knee; also serves as an attachment site for a ligament that holds the tibia in place |
Lateral Condyle of Femur | Side-most bump on the distal ends of the femur that bear weight while also allowing movement of bone |
Medial Epicondyle of Femur | Bumps on the medial side of the distal femur located just superior to the condyles; muscle attachment site |
Lateral Epicondyle of Femur | Bumps on the lateral side of the distal femur located just superior to the condyles; muscle attachment site |
Intercondylar Fossa | An attachment site for ligaments holding the femur and tibia together |
Patellar Groove | A small depression on the anterior side of the distal end of the femur. The patella moves within this groove when the leg moves. |
Patella | Flat bone that acts as a kneecap |
Tibia | The larger of the two bones that forms the lower leg |
Medial Condyle of Tibia | Region on the proximal end of the tibia that articulates with the condyles of the femur, located more towards the middle of the body |
Lateral Condyle of Femur | Region on the proximal end of the tibia that articulates with the condyles of the femur; located outwards from the body |
Intercondylar Eminence | The separation of the medial and lateral condyles of the tibia |
Tibial Tuberosity | Ligaments holding the patella in place attach here |
Medial Malleolus | The distal end of the tibia is an attachment site for ligaments holding the leg and foot bones together at the ankle |
Fibula | The smaller of the two bones that forms the leg |
Head of Fibula | Attaches the fibula to the proximal end of the tibia |
Lateral Malleolus | The distal end of the fibula is an attachment site for ligaments holding the leg and foot bones together at the ankle |
Tarsals | Refers to a cluster of seven bones that make up the midfoot and hindfoot |
Calcaneus | One of the seven tarsals; the largest of the tarsals making up the heel |
Talus | One of the seven tarsals; located by the ankle and is one of the bones that makes up the ankle joint |
Navicular | One of the seven tarsals; a small bone that resembles a boat due to how concave one of its surfaces are |
Cuboid | One of the seven tarsals; a small bone that is roughly cubical in shape |
Lateral Cuneiform | One of the seven tarsals; intermediate in size and on the lateral side of the foot compared to the other cuneiforms |
Medial Cuneiform | One of the seven tarsals; the largest of the cuneiforms and is situated on the medial side of the foot |
Intermediate Cuneiform | One of the seven tarsals; the smallest of the cuneiforms and is situation in between the other cuneiforms |
Metatarsals | The intermediate bones of the foot, between the tarsals and the phalanges |
Proximal Phalanges | The phalanges of the foot that are closest to the ankle. |
Middle Phalanges | The phalanges of the foot that are in between the proximal and distal phalanges. The big toe does not contain one. |
Distal Phalanges | The phalanges of the foot that are furthest from the ankle. |
