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 Bones of the fingers Bones of the palms Bones of the wrist Head, Radial Tuberosity, Ulnar Notch, Carpal Surface, Forearm (antebrachium) Trochlear Notch, Olercranon, Ulnar Tuberosity, Radial Notch, Head 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) Upper Arm (brachium) 1 Bones of the Os Coxa 2 Pubis 3 Pelvic Girdle 4 Auricular Surface 5 Iliac Fossa 6 Pubic Symphysis 7 Iliac Crest 8 Os Coxa 9 Ischial Tuberosity 10 Ischium 11 Components of Pelvic Girdle 12 Ischium Features 13 Ilium 14 Ilium Features fibrocartilage disk absorbs shock while walking & allows for childbirth Ilium, Ischium, Pubis 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 What you put your hands on when you rest your hands on your “hips” Site of muscle attachment What you sit on (“sits bone”) Site of muscle attachment (adductor magnus, hamstrings) Inferior, posterior portion of the coxa Ischial Tuberosity Largest of the 3 bones; Superior portions of the coxa; Articulates with the sacrum 3 bones that fuse during puberty at the acetabulum (hip joint) Large, smooth, concave surface Site of muscle attachment (internal hip muscles) Articulates with the auricular surface of the sacrum = sacroiliac (SI) joint 2 Coxa Iliac Crest, Iliac Fossa, Auricular Surface 1 Phalanges 2 Patella 3 Metatarsals 4 Femur 5 Components of the Tarsals 6 Components of the Lower Limb 7 Components of the Metatarsals 8 Components of the Fibula 9 Tarsals 10 Components of the Tibia 11 Components of the Phalanges 12 Components of the Femur 13 Tibia 14 Fibula 15 Components of the Patella Sesamoid bone - grows within the tendon; protects the knee when kneeling the "thigh"; Longest, strongest, and heaviest bone of the body; At an angle 7 in total; Only need to know Talus and Calcaneus 5 in total; named I-V from medial (big) to lateral (baby) Head, Lateral Malleolu Femur, Patella, Tibia, Fibula, Tarsals, Metatarsals, Phalanges Medial Condyle, Lateral Condyle, Medial Malleolus, Fibular Notch Bigger of the lower leg bones; Medial bone Bones of the toes Bones of the back foot 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 Smaller of the lower leg bones; Lateral bone Base & Apex Head, Greater Trochanter, Lesser Trochanter, Linea Aspera, Medial Condyle, Lateral Condyle, Patellar Surface Bones of the middle foot 1 Lateral Collateral Ligament (LCL) 2 Anterior Cruciate Ligament (ACL) 3 Posterior Cruciate Ligament (PCL) 4 quadricep tendon 5 menisci 6 Collateral Ligaments 7 Cruciate Ligaments 8 Medial Collateral Ligament (MCL) 9 patellar ligament 10 Knee anterior, behind patella, crosses in front of PCL 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) from muscle to the patella (above knee) from patella to the tibial tuberosity (below knee) stabilize the front and back of the tibiofemoral joint; ACL & PCL joint of femur, patella, tibia, fibula posterior, popliteal region fibrocartilage pads between the femoral and tibial condyles
