5 proximal, 4 middle, & 5 distal; numbered 1-5 from thumb to pinky - proximal & distal; numbered 2-4 from index to pinky - middle Trochlear Notch, Olercranon, Ulnar Tuberosity, Radial Notch, Head 5 in total; Not named but numbered I (Lateral, thumb) - V (Medial, pinky) Bones of the wrist Upper Arm (brachium) Bones of the fingers Head, Radial Tuberosity, Ulnar Notch, Carpal Surface, 8 in total; Only need to know scaphoid 1 Iliac Fossa 2 Auricular Surface 3 Pubic Symphysis 4 Ilium Features 5 Ilium 6 Iliac Crest 7 Ischial Tuberosity 8 Components of Pelvic Girdle 9 Os Coxa 10 Ischium Features 11 Ischium 12 Pubis 13 Pelvic Girdle 14 Bones of the Os Coxa Inferior, anterior portion of the coxa Articulates with the other coxa at the pubic symphysis fibrocartilage disk absorbs shock while walking & allows for childbirth Largest of the 3 bones; Superior portions of the coxa; Articulates with the sacrum Inferior, posterior portion of the coxa Large, smooth, concave surface Site of muscle attachment (internal hip muscles) Ischial Tuberosity Iliac Crest, Iliac Fossa, Auricular Surface What you sit on (“sits bone”) Site of muscle attachment (adductor magnus, hamstrings) 2 Coxa Articulates with the auricular surface of the sacrum = sacroiliac (SI) joint Ilium, Ischium, Pubis What you put your hands on when you rest your hands on your “hips” Site of muscle attachment attaches lower limbs to the trunk (sacrum), supports body weight, protects pelvic organs 3 bones that fuse during puberty at the acetabulum (hip joint) 1 Fibula 2 Components of the Tibia 3 Components of the Patella 4 Metatarsals 5 Femur 6 Components of the Femur 7 Components of the Phalanges 8 Components of the Fibula 9 Components of the Metatarsals 10 Tarsals 11 Patella 12 Components of the Tarsals 13 Tibia 14 Phalanges 15 Components of the Lower Limb Bones of the toes the "thigh"; Longest, strongest, and heaviest bone of the body; At an angle Base & Apex Head, Greater Trochanter, Lesser Trochanter, Linea Aspera, Medial Condyle, Lateral Condyle, Patellar Surface Smaller of the lower leg bones; Lateral bone 14 in total; 5 proximal, 4 middle, & 5 distal; numbered 1-5 from thumb to pinky - proximal & distal; numbered 2-4 from index to pinky - middle Bones of the middle foot Bones of the back foot 7 in total; Only need to know Talus and Calcaneus Head, Lateral Malleolu 5 in total; named I-V from medial (big) to lateral (baby) Femur, Patella, Tibia, Fibula, Tarsals, Metatarsals, Phalanges Bigger of the lower leg bones; Medial bone Medial Condyle, Lateral Condyle, Medial Malleolus, Fibular Notch Sesamoid bone - grows within the tendon; protects the knee when kneeling 1 Cruciate Ligaments 2 patellar ligament 3 Knee 4 Collateral Ligaments 5 quadricep tendon 6 Medial Collateral Ligament (MCL) 7 Lateral Collateral Ligament (LCL) 8 menisci 9 Posterior Cruciate Ligament (PCL) 10 Anterior Cruciate Ligament (ACL) Between medial femur and tibia; Prevents hyperabduction (keeping it from moving too far laterally) Stabilize the sides of the joint; LCL & MCL Between lateral femur and fibula; Prevents hyperadduction (keeping it from moving too far medially) joint of femur, patella, tibia, fibula anterior, behind patella, crosses in front of PCL fibrocartilage pads between the femoral and tibial condyles from muscle to the patella (above knee) posterior, popliteal region from patella to the tibial tuberosity (below knee) stabilize the front and back of the tibiofemoral joint; ACL & PCL
