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