Iliac Crest | top of hip bone |
Ischium | inferior, posterior portion of the pelvic girdle |
Ischial Spine | prominence, may hurt someones lap if you sit on them |
Lesser Sciatic Notch | open for sciatic nerve to pass through |
Obturator Foramen | hole formed by ischium, ilium, and pubis (blood vessels and nerves pass through this opening) |
Acetabulum | the fossa formed by the ilium, ischium, and pubis (is the socket for the head of the femur, creates the hip joint when the femur is attached) |
Pubis Symphysis | joins the pelvic girdle anteriorly |
Male Pelvic Structure | Hip Angle - narrow, taller Coccyx - points anteriorly Pubic Arch - less than 90 degrees Pelvic Cavity - deeper, oval shaped |
Female Pelvic Structure | Hip Angle - wider, shallow Coccyx - points inferiorly Pubic Arch - more than 90 degrees Pelvic Cavity - shallow, circular |
Femur | the bone of the thigh or upper hind limb, articulating at the hip and the knee |
Head | articulates with the acetabulum of the hipbone to form the hip joint |
Neck | a constricted part of bone just below the head, often breaks when your old |
Greater/Lesser Trochanters | attachment sites for buttocks and thigh muscles |
Patella | location anterior to the knee joint |
Patella Functions | protect knee joint, increase leverage of the quadriceps muscles, maintain the position of the tendon when knee is flexed |
Tibia | the inner and typically larger of the two bones between the knee and the ankle |
Tibial Tuberosity | attachment site for patellar ligament |
Medial Mallelous | articulates with the talus bone of ankle |
Fibula | the outer and usually smaller of the two bones between the knee and the ankle in humans |
Lateral Mallelous | articulates with talus bone of the ankle |
Tarsus | made from 7 tarsal bones |
Talus | ankle bones, articulates with tibia and fibula |
Calcaneus | heel bone, largest and strongest |
Metatarsals | 1-5 (big toe to pinky) |
