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