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