JARINGAN HEWAN (ANIMAL TISSUE)

VERTEBRATES TISSUETissue,groupofsimilarly structured cells that perform specialized functions for the survival of the organismTissue in vertebrates is divided into five kindsMeristematic tissueThis tissue is found in embryo development phase and in the end of young pipe bone, backbone marrow

2. Epithelia tissue (jaringan epitel)Function of this tissue is for covering (body or part of body organ) and protecting another tissue.Epithelia tissue consists of cells arranged denselya. Based on the number of cell layers: - single layer (simple) epithelia - multilayer (complex) epithelia

b. Based on the shaped of its cells:flat epithelia (squamosa): in kidney, lungs, blood vessels, skincubic (cuboid) epithelia: in surface of ovarium, eye lens, retinalong (columnar) epithelia: in respiration organ, digestion channels

Simple squamous epithelia tissue on the skin

Columnar epithelia tissue on the inner layer of human intestine

3. Bonding (supporting) Tissue (Jaringan pengikat/penyokong)The functions of bonding tissue as follows:a. to bond one tissue to another tissueb. to wrap organsc. to fill cavity between organsd. to transport oxygen and food substances to another tissuee. to transport metabolism waste to secretion organsf. to produce immunityg. to replace broken tissueh. to neutralize poisoni. to form supporting skeleton

Bonding tissue consists of four kindsOrdinary bonding tissue (jaringan ikat biasa); Example: tissue in muscle tendonSpecific bonding tissue (jaringan ikat khusus); Example the lipid tissue under the skinSupporting bonding tissue (jaringan ikat penyokong); Cartilage tissue and real bone tissue.Connecting bonding tissue (jaringan ikat penghubung) : Blood tissue and lymph tissue

Lipid tissue (adipose tissue)

SUPPORTING BONDING TISSUE:1. Cartilage tissue (jaringan tulang rawan):Dense matrix (condrite)Yellow and white fibres (collagen)Chondrosite (cell of cartilage tissue) which occupies a chamber (lacuna)2. Real bone tissue (jaringan tulang sejati):Its matrix has no elastic property, because contains organic salt: calc saltLamela (layers)Osteocyte cellsLacuna (small hollow)canaliculi

Real bone tissue

CONNECTING BONDING TISSUE:1. Blood tissue (jaringan darah)Blood tissue consists of :Blood plasma (plasma darah)Blood grains (butiran darah):- Red blood cell / erythrocyte (sel darah merah)- white blood cell / leucocyte (sel darah putih)- blood disk / thrombocyte (keping darah)

2. Lymph tissueLymph tissue consist of lymph liquid which circulates lymph vessels. Lymph liquid functions to transport lipid

Red and white blood cells

Blood disk (Thrombocyte)

Process of coagulation

4. Muscle tissue (jaringan otot) consists;Cells (fiber in shape)No intercellular matrixIts cytoplasm contains contractile fiber (myofibril)This tissue is divided into 3 kinds:a. skeletal muscle tissue (striped muscle)b. smooth muscle tissuec. cardiac muscle tissue

Skeletal muscle tissueCharacteristic:Its fibers has dark and light lines (striped muscle)Many nucleiWork under instructionFound in skeletal

Smooth muscle tissueCharacteristic:No dark and light linesIts cell has one nucleiIts does not work under instructionFound in inner organs: intestine and blood vessel

Cardiac muscle tissueCharacteristics:Its fibers has dark and light linesIts cell has nuclei placed centrallyBranching and interconnecting fibersIt does not work under instructionIt is found in the heart

Striated/stripe muscle tissue

Smooth muscle tissue

Cardiac muscle tissue

5. Nerve Tissue (jaringan saraf) consists of nerve cells (neurons) and nerve fibresFunction: as conductor of stimulation

This tissue is divided into three kinds:a. sensoric nerve tissue (jaringan saraf sensoris)b. Motoric nerve tissue (jaringan saraf motorik)c. Connector nerve tissue (jaringan saraf penghubung)

Nerve cells (neurons)

Nerve cell (neuron)
