Adipose tissue is made up of cells called adipocytes that collect and store fat in the form of triglycerides, for energy metabolism. A core feature of these tissues is that there is a minimal amount of matrix present. They are very different from the epithelial, muscle and nervous tissues. Generally, the tissue is made of several closely packed cells which are variously modified according to where they occur within the human body. C. loose connective tissue. … Connective tissue has relatively few cells separated by a large amount of extracellular matrix (as opposed to epithelial tissue which exhibits high cellularity). Why does Ella’s skin condition also affect her nutrition ... (See Connective Tissue Coloring). Neurons are the basic unit of nervous tissue. Proyash Roy. They perform a variety of functions that include protection, secretion, absorption, excretion, filtration, diffusion, and sensory reception. Separations in the bone that ech have individual blood supply. There are three types of cartilage: hyaline cartilage, elastic cartilage, and … Most rigid type of connective tissue, contains red marrow, stores and releases calcium, contains matrix mineral salt, support and protection, bone cells: osteocytes, lamallle, and osteons, heal quickly because of blood supply . 7. The type of intercellular matrix differs in different connective tissues. E. blood. Be able to label a picture of the matrix. Nervous tissue is found in the brain, spinal cord, and nerves.It is responsible for coordinating and controlling many body activities. As was true for loose connective tissue, the dense and skeletal connective tissues involve more than just cells; it is the non-living extracellular substances which determine the nature and function of the tissue. The nervous tissue is composed of two cell types: neurons and glia.The main function of nervous tissue is the processing of information coming from the external and internal environments, and then … It arises from epithelium: the embryonic neural plate. They are responsible for sensing stimuli and transmitting signals to and from different parts of an organism. Favorite Answer. A. cartilage. Cells in epithelial tissue or epithelium (epithelia; plural) are arranged in continuous sheets, in either single or multiple layers. Compare loose connective tissue to … 1 decade ago. Constriction of smooth muscle occurs under involuntary, autonomic nervous control and in response to local conditions in the tissues. A tissue is a group of cells, in close proximity, organized to perform one or more specific functions.. Question 18. Relevance.
