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