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