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