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