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