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