Living tissues are not just accumulations of tightly packed cells. Much of a tissue's volume is made up of extracellular space ('extra-' meaning 'outside' or 'beyond,' as ...Unlike epithelial tissue, which is composed of cells closely packed with little or no extracellular space in between, connective tissue cells are dispersed in a matrix. The matrix usually includes a large amount of extracellular material produced by the connective tissue cells that are embedded within it.The extracellular matrix of the connective tissues is composed of ground substance and fibers. It is present between the widely spaced cells that are often suspended in the ground substance. The matrix is responsible for the specific structure and function of the tissues as the matrix of bone is rigid and inflexible, but that of cartilage is ...A basement membrane is a thin extracellular matrix that separates the connective tissue from the epithelial tissue. The epithelia is on top of it. The main functions of the basement membrane are: Mechanical support, signaling cell survival, maintaining cell polarity, being a substrate for cell migration, keeping compartmentalization, and acting ...(a) Connective Tissue; (b) Epithelium (c) Muscle (d) Nervous tissue 1.___ Tissue type composed largely of nonliving extracellular matrix, important in protection and support 2.___The tissue immediately responsible for body movement 3.__The tissue that enables us to be aware of the external environment and to react to it. 4.__The tissue that lines body cavities and covers surfacesThis tissue has an extensive extracellular matrix, usually has many blood vessels, and provides oxygen and nutrients to overlying tissues. A. epithelial tissue B. connective tissue C. muscular tissue D. nervous tissue; Connective tissue is different from the other major tissue types in that A. it is made up of cells. B. it is not made up of cells.Select the correct statement regarding adipose tissue: A) Its primary function is nutrient storage. B) Mature adipose cells are highly mitotic. C) Most of the cell volume is occupied by the nucleus. D) It is composed mostly of extracellular matrix. Its primary function is nutrient storage. We have an expert-written solution to this problem! e)nerves. c)blood. A stratified epithelium is composed of ________. a)a tight layer of square cells attached to a basement membrane. a single layer of cells of variable height. b)multiple layers of cells, stacked from the basolateral side to the apical side. c)alternating layers of thick and thin cells.Nov 23, 2021 · The connective tissue in general is comprised of 3 groups of proteins: collagens, proteoglycans and a variety of different glycoproteins. In addition to the main weight-bearing structural proteins of connective tissue – the fibril forming collagens (discussed in Chap. 2) – as well as the often hydrophilic role of proteoglycan proteins (discussed in Chap. 6), growth factors (see Chap. 7 ... Flashcards. preischka22. Connective Tissue. fills space within the body, can be rigid (bone, cartilage) or flexible (areolar, adipose) Connective Tissue Functions. binds structures, support, protection, lipid storage, repair of damaged tissue, production of blood cells. Connective Tissue Cell Types. blasts, cytes, clasts.WebRecall that blood is a connective tissue. Like all connective tissues, it is made up of cellular elements and an extracellular matrix. The cellular elements—referred to as the formed elements—include red blood cells (RBCs), white blood cells (WBCs), and cell fragments called platelets.The extracellular matrix, called plasma, makes blood unique …Mar 5, 2023 · The extracellular matrix of both loose and dense connective tissue proper is composed of amorphous ground substance, extracellular fluid, and collagen and elastic fibers. The amorphous ground substance is a gelatinous material surrounding the fibers and permitting extracellular fluid to diffuse through. Connective tissue extracellular matrix (ECM) consists of an interwoven network of contiguous collagen fibers that regulate cell activity, direct biological function, and guide tissue homeostasis throughout life. Recently, ECM analogs have emerged as a unique ex vivo culture platform for studying healthy and diseased tissues and in the …WebThe FBN1 gene provides instructions for making a large protein called fibrillin-1. Learn about this gene and related health conditions. The FBN1 gene provides instructions for making a large protein called fibrillin-1. This protein is trans...e)nerves. c)blood. A stratified epithelium is composed of ________. a)a tight layer of square cells attached to a basement membrane. a single layer of cells of variable height. b)multiple layers of cells, stacked from the basolateral side to the apical side. c)alternating layers of thick and thin cells. The cutaneous membrane is a dry membrane exposed to air. Serous membranes line body cavities and organs. The cutaneous membrane, a "dry" membrane exposed to air, consists of a keratinized, stratified squamous epithelium called, the epidermis, and an underlying layer of connective tissue called, the dermis.Web.
