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