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