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