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