Nursingmuscloskeletal system UniversityAll boards Created by: AmberJ1Created on: 29-04-17 19:46 what does the system consist of? muscle, bones, joints and supporting structures 1 of 41 what are the 3 types of muscle? smooth muscle, skeletal muscle, cardiac muscle 2 of 41 what is smooth muscle? non-striated, involuntary, located in blood vessels or hollow organs 3 of 41 what is skeletal muscle? works in pairs, striated, voluntary, made of hundreds of muscle fibres 4 of 41 what is cardiac muscle? only found in the heart, striated, involuntary 5 of 41 functions of muscle tissue body movements, stabilising body positions, producing heat, storing & moving substances 6 of 41 what are the 3 layers connective tissue in skeletal muscle? outer epimusium, central perimysium & inner endomusium 7 of 41 what does the sarcoplasmic reticulum contains? calcium and myoglobin 8 of 41 what are the thick filaments in the sarcomere? myosin 9 of 41 what are the thin filaments in the sarcomere? actin, tropomyosin & troponin 10 of 41 true or false, thin filaments are attached to Z discs true 11 of 41 true or false, each actin has a myosin binding site but is blocked by tropomyosin when relaxed true 12 of 41 true or false, calcium diffuses into sarcoplasm and binds to tropomyosin false - binds to troponin 13 of 41 how can ATP be created? Creatine phosphate, anaerobic respiration and aerobic repsiration 14 of 41 what is anaerobic respiration? breaks down stored glycogen into ATP for about 2 minutes 15 of 41 what is aerobic repsiration? uses o2 to produce enough ATP for prolonged action 16 of 41 what is a twitch tension brief response to a single action potential stimulating muscle fibre 17 of 41 whats a slow oxidative skeletal muscle? called red fibres, lots of myoglobin, prolonged and sustained contractions 18 of 41 whats a fast oxidative-glycolytic skeletal muscle? fibres that contain lots of myoglobin and glycogen, contracts and relaxes quckily 19 of 41 whats a fast glycolytic skeletal muscle? fibres containing large amounts of glycogen and fatigue quckily 20 of 41 functions of bones & skeletal system? supporting framework, protection, assists in movement, haemopoiesis 21 of 41 what are the 4 types of bones? long, flat, short, irregular 22 of 41 what does the epiphyses part of the bone do? ends of the bone 23 of 41 what does the diaphysis part of the bone do? main part of the bone 24 of 41 what does the epiphyseal plate part of the bone do? growing part of the bone 25 of 41 what does the articular cartilage part of the bone do? joins bone to bone 26 of 41 what does the periosteum part of the bone do? covering of the bone 27 of 41 what does the endosteum part of the bone do? thin lining of cavity 28 of 41 what is osseous tissue? extensive extracelluar matrix and widely separated cells 29 of 41 what are the 4 types of osseous tissue? osteoprogenitor cell, osteoblasts, osteocyte, osteoclast 30 of 41 what is compact bone tissue? arranged in osteons that run longitudinally, dense bone 31 of 41 what is spongy bone tissue? consists of units called trabeculae, irregular latticework, site of haemopoiesis, forms short, flat & irregular bones 32 of 41 Synarthrosis joint (functional) immovable joint 33 of 41 Amphiarthrosis joint (functional) slightly moveable joint 34 of 41 Diarthrosis joint (functional) freely moveable joint 35 of 41 Fibrous joint (structual) held by dense irregular connective tissue 36 of 41 Cartilaginous joint (structual) held by cartilage 37 of 41 Synovial joint (structual) ligaments support joint 38 of 41 Types of synovial joints plane, hinge, pivot, saddle, ball&socket 39 of 41 what are tendons? connects bone to muscle, great tensile strength 40 of 41 what are ligaments? fibrous connective tissue attaching bone to bone 41 of 41
