Tissues of the Body

By Barry Persing

Epithelial Tissue

Epithelial tissue can be classified by its cell shape and cell arrangement. The shapes are as follows: squamous, which are flat and scale-like; cuboidal, which are cube shaped; and columnar, which are tall and elongated. There two arrangements, which are simple, or single layered suited for absorbing nutrients as well as filtration and excretion, and stratified, which are multi-layered suited for protection. These tissues are best for this job since the simple arrangements are thin enough to permeable, and the stratified arrangements allow layers to be lost in order to protect. The first image details the different types of Epithelial tissue in a mouse, showing where they are located. The second image details a few different types of epithelial tissue.

Connective Tissue

Connective tissue has multiple functions. Given its density by its extracellular matrix, it connects, binds and supports structures; bears weight and abuse; protects and cushions organs; insulates and stores fat; transports nutrients throughout the body as blood; and lastly, it serves as a supporting framework for our body as bone. All these functions are split between the six types of connective tissues: bone, cartilage, dense connective tissue, loose connective tissue, and blood. These tissues are the best for these jobs due to their characteristics and densities, such as bone being extremely dense in order to provide structure. The first image shows an example of loose connective tissue. found here: https://aandpeasyaspanda.files.wordpress.com/2011/10/areolar1.jpg. The second image shows the different types of connective tissues and where they can be found in the body and was found here: https://www.quia.com/files/quia/users/lmcgee/Systems/9AP_Chapter_40_AnimalForm_and_Function/Connective_Tissue_Types.jpg The facts were all derived from the notes.

Muscular Tissue

Muscular tissue can be categorized into three types: Skeletal, which is used for movement and found in areas such as the biceps and hamstrings; Smooth, which is used to move blood, food, and waste through organs; and cardiac, which are the walls of the heart that contract to produce the heartbeat. The overall purpose of muscular tissue is movement, and they are the only tissues strong enough and flexible enough to contract for movement, which is why they are best suited for the job. The first image shows an example of muscular tissue and was found here: https://s3.amazonaws.com/user-media.venngage.com/273537-d7c16a437649cb9484db2392a301f5be.jpg. The second image shows the different muscle types and where they are located.

Nervous Tissue

Nervous tissue is the last type of tissue in the body. it is found in the brain, spinal cord, and nerves. The purpose of nervous tissue is to generate and transmit nerve impulses to and from the body organs via neurons. This tissue is best suited for this purpose as it is the only tissue able to transmit nerve impulses. The first image displays an example of nerve tissue and was found here: http://www.nail-course.com/wp-content/uploads/2013/12/nervous_tissue.jpg. The second image depicts the parts of a neural tissue and was found here: https://upload.wikimedia.org/wikipedia/commons/7/73/Blausen_0672_NeuralTissue.png. Facts were all derived from class notes
