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