1 dr. Dea Amanda dr. Dea Amanda Program Studi Ilmu Keperawatan Program Studi Ilmu Keperawatan Unitri Malang Human anatomy SKELETAL SYSTEM

2 Anatomi.. : Ilmu yg mempelajari ttg struktur tubuh Tubuh  sistem organ  organ  jaringan  sel Sistem organ: muskuloskeletal, GIT, urinary, reproductive, respiratory system, cardiovascular Organ: cardia, gaster, ren, uterus, prostat, pulmo, ureter

3 Fisiologi.. : Ilmu yg mempelajari ttg proses tubuh N Cardiovaskuler: –Memompa darah ke seluruh tubuh u/ myalurkan O2 & nutrisi GIT: –Mencerna makanan u/ diserap & bahan bakar tubuh Muskuloskeletal: –bergerak

4 Anatomical Position & Terminology Posisi Anatomis: the Body is erect/upright Legs together Feet are parallel, directed forwards, flat on the floor Arms at the sides of the body Palms turned forward, with fingers pointing downwards

5 Istilah2.. (=terminology) Superior (=cranial) vs Inferior (=caudal) Anterior (=ventral) vs Posterior (=dorsal) Medial vs Lateral Internal (=deep) vs Eksternal (=superfisial) Proksimal vs Distal

8 Bidang2 Tubuh.. Sagital (kiri-kanan ) ; mid-sagital: (pas tengah) Koronal (depan-belakang) Transversal (superior-inferior)

9 Skeletal System Structure: –Bones –Cartilage –Joints –∑ tulang:206

10 Skeletal System.. (2) FunctionFunction 1.Support :penopang tubuh 2.Protection :melindungi organ2 vital 3.Movement :bergerak saat kontraksi otot 4.Hematopoiesis :terlindung dlm sutul, produksi sel darah 5.Mineral storage

11 Klasifikasi tulang.. (brdsrkn bentuk) Tulang panjang : ada beda panjang>lebar (femur, tibia, humerus) Tulang pendek : spt kubus (carpal, tarsal) Tulang pipih: proteksi (skull, ribs, scapula) Tulang ireguler: bentuk aneh (vertebrae, face)

12 General structures of bone Bone substance –compact bone –spongy bone ※ flat bones  2 layers compact bone (outer plate & inner plate); spongy bone in the middle

13 Long Bone Structure.. Diaphysis: di tgh Epiphysis: –di ujung prox&dist –Tdd tulang spongious dikelilingi tulang kompak Medullary cavity: –rongga dlm diafisis; –dilapisi endosteum; –Berisi: yellow bone marrow.

14 Long Bone Structure.. Metaphysis: –Daerah dmn diafis bergabung dg epifis Epiphyseal plate: –Mitosis>>, u/ elongasi –Saat pertumb slesai  epiphyseal line Articular cartilage: –Kartilago melapisi tiap epiphysis.

15 Periosteum: –Outer or fibrous layer –Inner layer  vascular & contains osteoblasts –Tempat menempelnya tendon

16 Long Bone Structure.. Figure 6.3

17 Histologi..

18 Histologi.. (2) Central Canal: circular channel  contains blood, lymphatic vessels, & nerves. (Concentric ) Lamellae: calcified matrix surrounding a vertically oriented blood vessel. Lacuna: a small hollow space, contains osteocytes. Canaliculus: a small channel  connects lacunae to each other, & to the central canal.

19 Bone Formation.. Terdapat bbrp tipe sel tulang, a.l: Sel osteogenik :sel progenitor (=stem sel) Osteoblast –sel2 tulang mghasilkan osteoid –Calcium & mineral lain  mengeraskan osteoid Osteosit :osteoblast trapped inside osteoid  develop jd osteosit Osteoklas :bone digestion - sel pghancur tulang  demineralisasi sel tulang

20 Bone Cell Types

21 Bone Formation.. = osifikasi Dimulai pd mgg ke-4 dlm kandungan Trdpt 2 cara: 1.Endochondral – mll thp kartilago Kondrosit (sel tlg rwn) hipertrofi  kalsifikasi 2.Intramembranous –lgsg terbentuk sbg tulang keras

22 Long Bone Formation and Growth..

23 Bone Growth in Length.. Epiphyseal plate –Cartilage cells in this plate divide rapidly. –Zone of proliferating cartilage. Between ages 18-25, the epiphyseal plates close. –Cartilage cells in the plate stop dividing and bone replaces the cartilage.  Growth in length stops at age 25.

24 Bone Growth in Width..

25 Bone Remodeling.. Saat massa tulang optimum telah tercapai  remodelling mjd proses utama pd tulang Fungsi: (1) memperbaiki kerusakan mikro tulang (2) mempertahankan kekuatan tulang (3) men-supply Ca dari tulang untuk mempertahankan kadar Ca serum.

26 Bone Remodeling.. Hasil akhir proses remodelling: tulang yg diresorpsi diganti dg tulang baru Pembentukan & resorpsi tulang  proses normal, & continuous

27 SKELETON (Kerangka Tulang) Axial : Skull 22 Auditory ossicles 6 Hyoid bone1 Vertebral column26 Ribs and sternum Appendicular : Upper extremity64 Lower extremity Total206 Axial Skeleton: merupakan tulang axis dari tubuh  cranium, vertebrae, costae, sternum Appendicular Skeleton: berbungan dengan penyusun tubuh :  extremitas atas, bawah, & pelvis

28 The Axial & Appendicular Skeleton Slide 5.20b Copyright © 2003 Pearson Education, Inc. publishing as Benjamin Cummings Figure 5.6

29 Joints.. (=articulation) : tempat pertemuan 2 tulang / lebih Klasifikasi: (immovable) a.Synarthrosis (immovable) (slightly movable) b.Amphiarthrosis (slightly movable) (freely movable) c.Diarthrosis (freely movable)

30 Synarthrosis.. ≠ dpt bergerak Tulang yg 1 dg yg lain dihubungkan dg jar. fibrosa ContohContoh: –Sutura pd tlg2 tengkorak –Tibia-fibula (distal)

31 Amphiarthrosis.. dpt sedikit bergerak Ujung2 tulangnya dibungkus tulang rawan hyalin Contoh:Contoh: –Symphisis pubis –Intervertebral joints

32 Diarthrosis.. (=sendi synovial) Sendi yg dpt digerakkan dg bebas Memiliki rongga sendi Ujung2 tulang dilapisi tulang rawan hyalin Contoh:Contoh: –Lutut –Siku

33 Pergerakan Sendi.. FleksivsEkstensi AbduksivsAdduksi Rotasi PronasivsSupinasi
