Matching Pairs Unit 2 Part 3: The Appendicular SkeletonOnline version Information on the appendicular portion of the skeleton and its features by Abigail Scott 1 Bones of the Appendicular Skeleton 2 Functions of the Appendicular Skeleton Vertical support, support the head, protect the spinal cord Upper: Clavicle, Scapula, Humerus, Radius, Ulna, Carpals, Metacarpals, Phalanges Lower: Coxa, Femur, Tibia, Fibula, Tarsals, Metatarsals, Phalanges 1 Supraspinous Fossa 2 Infraspinous Fossa 3 Scapula Features 4 Fossae 5 Scapular Spine 6 Pectoral Girdle (Shoulder) 7 Acromial End 8 Glenoid Fossa 9 Sternal End 10 Scapula 11 Acromial Process 12 Clavicle 13 Subscapular Fossa 14 Clavicle Features 15 Coracoid Process 16 Consists of Sternal end & acromial end "collarbone" Lateral For head of humerus superior to the scapular spine Site of muscle attachment (supraspinatus) Anterior side of the scapula (closest to ribcage) Site of muscle attachment (subscapularis) Inferior to the scapular spine Site of muscle attachment (infraspinatus) The ridge between Supraspinous & Infraspinous fossae Site of muscle attachment (trapezius, etc.) Attaches the upper limbs to the trunk (the sternum) Supraspinous, Infraspinous, Subscapular, & Glenoid Acromial Process, Coracoid Process, Scapular Spine, & Fossae "shoulder blade" Clavicle (2) & Scapula (2) Smaller lateral projection, more anterior Site of muscle attachment (pectoralis minor & biceps brachii) Articulates with the clavicular notch of the manubrium (sternum) = Sternoclavicular joint LARGER lateral projection, more posterior Articulates with the acromial end of the clavicle = Acromioclavicular joint Articulates with the acromial process of the scapula = Acromioclavicular joint 1 Radius Components 2 Humerus Components 3 Carpals Components 4 Ulna Components 5 Phalanges Components 6 Radius & Ulna 7 Carpals 8 Humerus 9 Metacarpals 10 Parts of the Upper Limb 11 Metacarpals Components 12 Phalanges Bones of the palms Forearm (antebrachium) Bones of the wrist Upper Arm (brachium) 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 8 in total; Only need to know scaphoid Head, Greater Tubercle, Lesser Tubercle, Deltoid Tuberosity, Medial Epicondyle, Lateral Condyle, Capitulum, Trochlea, Olecranon Fossa Trochlear Notch, Olercranon, Ulnar Tuberosity, Radial Notch, Head Humerus, Radius, Ulna, Carpals, Metacarpals, & Phalanges Bones of the fingers Head, Radial Tuberosity, Ulnar Notch, Carpal Surface, 5 in total; Not named but numbered I (Lateral, thumb) - V (Medial, pinky) 1 Ischial Tuberosity 2 Pubic Symphysis 3 Pelvic Girdle 4 Auricular Surface 5 Ilium 6 Os Coxa 7 Components of Pelvic Girdle 8 Ischium Features 9 Iliac Crest 10 Iliac Fossa 11 Pubis 12 Ischium 13 Bones of the Os Coxa 14 Ilium Features Large, smooth, concave surface Site of muscle attachment (internal hip muscles) attaches lower limbs to the trunk (sacrum), supports body weight, protects pelvic organs 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 Inferior, posterior portion of the coxa 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) 3 bones that fuse during puberty at the acetabulum (hip joint) 2 Coxa fibrocartilage disk absorbs shock while walking & allows for childbirth Ilium, Ischium, Pubis Iliac Crest, Iliac Fossa, Auricular Surface Ischial Tuberosity Largest of the 3 bones; Superior portions of the coxa; Articulates with the sacrum 1 Fibula 2 Femur 3 Patella 4 Components of the Fibula 5 Components of the Metatarsals 6 Tarsals 7 Components of the Tarsals 8 Phalanges 9 Metatarsals 10 Components of the Patella 11 Components of the Tibia 12 Components of the Femur 13 Components of the Lower Limb 14 Tibia 15 Components of the Phalanges Sesamoid bone - grows within the tendon; protects the knee when kneeling Smaller of the lower leg bones; Lateral bone Head, Lateral Malleolu Base & Apex 7 in total; Only need to know Talus and Calcaneus 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 Femur, Patella, Tibia, Fibula, Tarsals, Metatarsals, Phalanges 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 Bones of the toes 5 in total; named I-V from medial (big) to lateral (baby) Head, Greater Trochanter, Lesser Trochanter, Linea Aspera, Medial Condyle, Lateral Condyle, Patellar Surface 1 Knee 2 Anterior Cruciate Ligament (ACL) 3 Lateral Collateral Ligament (LCL) 4 patellar ligament 5 menisci 6 Collateral Ligaments 7 Posterior Cruciate Ligament (PCL) 8 quadricep tendon 9 Cruciate Ligaments 10 Medial Collateral Ligament (MCL) posterior, popliteal region from muscle to the patella (above knee) Between lateral femur and fibula; Prevents hyperadduction (keeping it from moving too far medially) Stabilize the sides of the joint; LCL & MCL joint of femur, patella, tibia, fibula fibrocartilage pads between the femoral and tibial condyles Between medial femur and tibia; Prevents hyperabduction (keeping it from moving too far laterally) anterior, behind patella, crosses in front of PCL stabilize the front and back of the tibiofemoral joint; ACL & PCL from patella to the tibial tuberosity (below knee)
