Nicola McLaren MSc Following are the substantial difference between epithelial and connective tissues: Epithelial tissue is made up of the cell and a small amount of intercellular matrix, while connective tissues are made up of the cell and a huge amount of intercellular matrix. For instance which epithelial tissue is found in the lips. Epithelial tissue is divided into two major types which are further divided into several other types; Connective tissues are also divided into various types based on the type of cells and the components of the extracellular matrix; Epithelial tissue is less abundant than connective tissue. Compare and contrast epithelial tissue with the other types of tissue in the body. These produce reticular fibers arranged in an interlaced network (reticulum), similar to dense irregular connective tissue. Compare and contrast somatic and germ cells. These types are bounded by blood capillaries and hence gain nutrition from there. epithelial tissue difference from connective tissue, -epithelial tissue has many cells tightly packed together and is avascular, connective tissue difference from epithelial tissue, -connective tissue has relatively few cells with lots of extracellular material, common bond between epithelial and connective tissue.

Compare and contrast human nails, claws, and equine hoofs. - The five different types of connective tissue include bone, cartilage, blood, dense connective, and loose connective tissues. Recall that tissues are groups of similar cells carrying out related functions. Besides, it also transports waste materials to organs like kidney and liver. It consists of a liquid matrix called as the plasma, in which blood cells are present. A stratified layer epithelium acts as that protective layer. Where filtration occurs, there is simple squamous epithelium. These lamellae circumvent around a central canal (Haversian canal) which serve for the passage of neurovasculature that supplies the bone and house the cells. Equipment: Microscopes and histological slides. Difference Between Epithelial and Connective Tissue This page will explain what is connective tissue and present you with an overview of its types. Blood and lymph are also connective, can't hear what's being said and can't read what's written, nice video, more detailed explanations needed though. It develops from the endoderm or mesoderm or ectoderm from the embryological germ layer. (c) Give an example of each. It matures into other types of connective tissues, muscles, vessels, mesothelium and the urogenital system.

Describe how the structure of epithelial tissue relates to its function. Cartilage is thin, avascular, flexible and resistant to compressive forces. lines every body surface and all body cavity; thus it forms both the external and internal lining of many organs, and it constitues the majority of glands. (a) Identify the 4 types of tissue in the body. Endoscopy of the retroperitoneal area offers a less damaging approach to several structures that are accessible only with difficulty, for instance the sympathetic trunk, the lymphatic trunk, and. These tissues often interact with each other for the viability and functioning of an organ. Over here and over here. When dormant, they are called osteocytes. The functions of four different body tissues. Muscle tissue is divided into three types based on location and function: skeletal, cardiac, and smooth. The tendons and ligaments found throughout the body act as a connecting medium for bones, muscles, and cartilages. usually release hormones but into the bloodstream, not to the target organ directly. And what exactly are these "fibres" that constitute the matrix?
