Only need to know scaphoid Forearm (antebrachium) Bones of the palms 5 in total; 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 Upper Arm (brachium) Trochlear Notch, Olercranon, Ulnar Tuberosity, Radial Notch, Head Humerus, Radius, Ulna, Carpals, Metacarpals, & Phalanges Head, Greater Tubercle, Lesser Tubercle, Deltoid Tuberosity, Medial Epicondyle, Lateral Condyle, Capitulum, Trochlea, Olecranon Fossa Head, Radial Tuberosity, Ulnar Notch, Carpal Surface, 1 Ischial Tuberosity 2 Ischium 3 Iliac Fossa 4 Os Coxa 5 Ischium Features 6 Bones of the Os Coxa 7 Components of Pelvic Girdle 8 Pubic Symphysis 9 Pubis 10 Pelvic Girdle 11 Ilium Features 12 Ilium 13 Iliac Crest 14 Auricular Surface 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) 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 Iliac Crest, Iliac Fossa, Auricular Surface 3 bones that fuse during puberty at the acetabulum (hip joint) Ilium, Ischium, Pubis Large, smooth, concave surface Site of muscle attachment (internal hip muscles) fibrocartilage disk absorbs shock while walking & allows for childbirth What you put your hands on when you rest your hands on your “hips” Site of muscle attachment Ischial Tuberosity 2 Coxa Inferior, posterior portion of the coxa Articulates with the auricular surface of the sacrum = sacroiliac (SI) joint 1 Femur 2 Components of the Fibula 3 Phalanges 4 Components of the Metatarsals 5 Components of the Lower Limb 6 Tibia 7 Components of the Phalanges 8 Tarsals 9 Components of the Tarsals 10 Metatarsals 11 Patella 12 Components of the Femur 13 Components of the Tibia 14 Fibula 15 Components of the Patella Bigger of the lower leg bones; Medial 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 Head, Greater Trochanter, Lesser Trochanter, Linea Aspera, Medial Condyle, Lateral Condyle, Patellar Surface 5 in total; named I-V from medial (big) to lateral (baby) Base & Apex Bones of the back foot Head, Lateral Malleolu Bones of the toes Smaller of the lower leg bones; Lateral bone Bones of the middle foot the "thigh"; Longest, strongest, and heaviest bone of the body; At an angle Medial Condyle, Lateral Condyle, Medial Malleolus, Fibular Notch Femur, Patella, Tibia, Fibula, Tarsals, Metatarsals, Phalanges 7 in total; Only need to know Talus and Calcaneus Sesamoid bone - grows within the tendon; protects the knee when kneeling 1 Knee 2 Posterior Cruciate Ligament (PCL) 3 Collateral Ligaments 4 patellar ligament 5 menisci 6 quadricep tendon 7 Anterior Cruciate Ligament (ACL) 8 Lateral Collateral Ligament (LCL) 9 Medial Collateral Ligament (MCL) 10 Cruciate Ligaments joint of femur, patella, tibia, fibula anterior, behind patella, crosses in front of PCL Between lateral femur and fibula; Prevents hyperadduction (keeping it from moving too far medially) from patella to the tibial tuberosity (below knee) posterior, popliteal region fibrocartilage pads between the femoral and tibial condyles stabilize the front and back of the tibiofemoral joint; ACL & PCL Stabilize the sides of the joint; LCL & MCL Between medial femur and tibia; Prevents hyperabduction (keeping it from moving too far laterally) from muscle to the patella (above knee)
