name and explain all the connective tissues present in our body.

There are four types of connective tissues found in the human body:1. Connective tissue propera. Loose Connective Tissuei. Areolarii. Adiposeiii. Reticularb. Dense Connective Tissuei. Dense regularii. Dense irregulariii. Elastic2. Cartilagea. Hyalineb. Elasticc. Fibrocartilage3. Bone (osseous tissue)4. BloodObserving Connective Tissues:Areolar Tissue:1. Obtain a slide of areolar tissue andproper mount it on the slide.2. Notice as you examine the tissue thatit is composed of a jumble of fibersand cells. Areolar tissue is a looseconnective tissue type and has a verydiffuse arrangement.3. The cells (dark spots within thetissue) are called fibroblasts (fibro=fiber, blast= to make or create). Theseare the cells responsible for secretingthe fibers present. The larger fibers(typically pink) are called collagenfibers. The small black fibers areelastic fibers. Collectively, the fibersand the rest of the substancesurrounding the cells would bereferred to as the matrix.4. For additional images, click HERE.Adipose Tissue:1. Obtain a slide of adipose tissue (oruse a kidney or trachea slide).2. Use proper technique to mount theslide and locate the tissue.3. Adipose tissue appears as large,irregular, bubble-like cells lumpedtogether.4. The cells that you are observing aresuspended in a matrix similar to theprevious slide. The cells themselvesare filled with fat, which is used asstored energy, insulation, and protection.5. For additional images, click HERE. Reticular Tissue:1. Obtain a slide of reticular tissue.Use proper technique to place theslide on the stage and locate thetissue.2. Notice the evident cells (reticularcells) and the large, dark fibers(reticular fibers).3. These fibers form a soft internalskeleton that support the cells ofcertain organs, such as the spleen,lymph nodes, and bone marrow.4.

Notice the orderly fibers runningthroughout the tissue. Thesefibers are collagen fibers.3. Embedded within the fibers arethe fiber-producing cells calledfibroblasts.4. This tissue forms tendons andligaments needed to connectmuscles to bones and bones toother bones.5. For additional images, clickHERE.Dense Irregular Connective Tissue:1. Obtain a slide of skin. Use propertechnique to mount the slide andto locate the tissue.2. The middle layer of the skin iscalled the dermis, and it iscomposed of dense irregularconnective tissue. Thecomposition of the tissue is thesame as that of dense regulartissue, but the components are notarranged as orderly as in thattissue.3. For additional images, clickHERE.Hyaline Cartilage:1. Obtain a trachea slide or a slidelabeled hyaline cartilage. Use propertechnique to mount the slide andlocate the tissue.2. Earlier, we observed the lining of thetrachea. Below that layer of tissue,we will find rings of hyalinecartilage embedded within the organto provide structure and support.3. The hyaline cartilage will have asmooth, amorphous (no form)matrix with cells suspended withinit. The matrix is compact fibers ofcollagen and the cells producing thematrix are called chondrocytes.They are contained within tinychambers called lacunae (littlelakes).4. For additional images, click HERE.Elastic Cartilage:1. Obtain a slide of elastic cartilage.Use proper technique to mount theslide and locate the tissue.2. Notice the large chondrocyteslocated in the lacunae.3. Also notice the presence of elasticfibers within the matrix of the tissue.While the tissue is similar incomposition to hyaline cartilage, theaddition of more elastic fibers allowsit to stretch and maintain its shape.This type of tissue is found formingmost of the structure of the externalear.4. For additional images, click HERE.Fibrocartilage:1. Obtain a slide of fibrocartilage. Useproper technique to mount the slideand locate the tissue2. Fibrocartilage is found forming theintervertebral discs in the spinalcolumn, the pubic symphysis, and inthe discs of the knee. While itscomposition is similar to that ofhyaline cartilage, it is not as firm andpossesses more noticeable collagenfibers.3. The cells present are still referred toas chondrocytes and are found inlacunae in this tissue as well.4. For additional images, click HERE.Bone (Osseous) Tissue:1. Obtain a slide of ground bone. Useproper technique to mount the slideand locate the tissue.2. Bone is arranged in concentric ringstructures called osteons. In thecenter of each ring is a structurecalled a Haversian canal. Thiscanal carries blood vessels throughthe bone to nourish the cellsembedded within the tissue.3. Around the Haversian canal, ringsof bone tissue from called lamellae.Within these rings are the chamberscalled lacunae that would containthe cells. The cells themselves arecalled osteocytes (osteo= bone,cyte= cell).4. Radiating out from the lacunae aretiny channels that allow interactionof the cells with the blood supply.These tiny channels are calledcanaliculi.5. For additional images, click HERE.Blood:1. Obtain a blood smear slide. Useproper technique to mount andlocate the tissue.2. Students typically do not considerblood to be a tissue due to its liquidstate. However, it meets all thecriteria set forward to be designateda connective tissue.3. Notice that there are two types ofcells easily recognizable; red bloodcells (erythrocytes) and white bloodcells (leukocytes). Also seenamong the cells are tiny fragmentsof cells called platelets.4. The liquid portion of blood is thematrix. This part is typically calledplasma and is made up of water,salts, gases, and proteins (nonlivingmaterials). You will learn moreabout blood as a tissue, includingthe functions of the components inAP2. For now, we want to be able to recognize the major components.If you like than thumbs up
