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