Tissue engineering is a radically new concept for the treatment of disease and injury. Up ↑ Animal tissues NERVOUS TISSUE N ervous tissue develops from the embryonic ectoderm, the layer covering the embryo that becomes the epidermis. Nervous tissue consists of nerve cells known as neurons (cell body, axon, ... are mature bone cells and develop as osteoblasts become encased in mineralized matrix. A. cartilage. Epithelial tissue covers surface areas of the body and contains no extracellular matrix. The English word "tissue" derives from the French word "tissue", meaning that … These mature cells in the lacunae are called chondrocytes. Join. All have a common embryonic origin known as mesenchyme. Adipose tissues additionally serve as insulation to help maintain body temperatures, allowing animals … Some tissues help in transportation such as the blood which is a connective that helps in transportation of the cells needed to supply oxygen and also transport other nutrients in the body ; Some tissues … … Constriction of smooth muscle occurs under involuntary, autonomic nervous control and in response to local conditions in the tissues. The matrix of blood is not fibrous though and is the plasma. 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. It provides support and shock absorption for bones and organs, and you find it in the dermis which is the middle layer of the skin, tendons and ligaments. Ask Question + 100. Matrix contains fibers (made by fibroblast cells) and other materials Elastic fibers – made of elastin and stretch easily, then recoil (also called yellow fibers) Collagen fibers – made of collagen and do not stretch (much) but are strong and flexible (also called white fibers or collagenous fibers) Major types of connective tissues. Favorite Answer. Epithelial tissues are widespread throughout the body. When these cells slow down, they reside is small spaces called lacunae. Why does Ella’s skin condition also affect her nutrition ... (See Connective Tissue Coloring). Epithelial Tissues. Like all tissue types, it consists of cells surrounded by a compartment of fluid called the extracellular matrix (ECM). _dense_____ - the dermis of … … Epithelial tissue is a type of animal tissue, consisting of closely aggregated polyhedral cells connected firmly to one another in the form of cellular sheets that line the interior of hollow organs and cover the body surface.. 1 decade ago. Cartilage: This connective tissue is relatively solid and is a non-vascularized tissue (does not have a blood supply). Which of the following helps in repair of tissue and fills up the space inside the organ? C. loose connective tissue. Several epithelial tissues are capable of secretion and may be known as the glandular epithelium, or more simply, as glands. Neuroglia, or support cells, surround the neurons; transmit information in the form of electrical charges that occur across the cell membrane called action potentials (brain, spinal cord & nerves); support, protect and form specialized sheaths around axons (neuroglia) Name the four primary tissue types: Cells of epithelial tissue form sheets that cover the body and organ surfaces. Like connective tissues, there is also matrix filling the … By definition, tissues are absent from unicellular organisms. Mesenchyme’s are undifferentiated loose connective tissue that are capable of developing into connective tissue … It does not have fibers like most other connective tissue. … Neurons are the basic unit of nervous tissue. 14.Using the key, choose the best response to identify the CT described below? A core feature of these tissues is that there is a minimal amount of matrix present. Tissue, in physiology, a level of organization in multicellular organisms; it consists of a group of structurally and functionally similar cells and their intercellular material. Connective Tissue Dense Connective Tissue, Cartilage, Bone, Joints . Organs are then formed by the functional grouping together of multiple tissues. The cells are joined together by special areas known as cell junctions. Question 18. In what tissue would you expect to fund very little, if any, extracellular matrix? Because they have no capillaries of their own, the epithelial tissues receive oxygen and nutrients from the blood supply of the underlying connective tissue. (a) The nature of matrix differs according to the function of the tissue (b) Fats are stored below the skin and in between the internal organs (c) Epithelial tissues have intercellular spaces between them (d) Cells of striated muscles are multinucleate and unbranched; The water conducting tissue generally present in gymnosperm is (a) vessels Connective tissue is found between other tissue types and organs. Nervous tissue Neuron consists of dendrites, a cell body a nd a long axon. Nervous tissue is found in the brain, spinal cord, and nerves.It is responsible for coordinating and controlling many body activities. 7. - macrophages, mast cells, fibroblasts, elastic fibers, collagen fibers, ground substance). They perform a variety of functions that include protection, secretion, absorption, excretion, filtration, diffusion, and sensory reception. Some tissues are used more than once. There are different types of connective tissues with different functions. Here are some more types of connective tissue. Nerve cell does not contain (a) axon (b) nerve endings (c) tendons (d) dendrites. Epithelial Tissue. They are responsible for sensing stimuli and transmitting signals to and from different parts of an organism. Answer Save. We have blood. Matrix is formed by osteoblasts, Matrix is the material located between the cells. just looking for an explanation, please. All connective tissue is made up of cells, fibres (such as collagen) and extracellular matrix. This tissue type does not have a blood supply, unlike the connective tissue. Generally, the tissue is made of several closely packed cells which are variously modified according to where they occur within the human body. … 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 .
