Tendinitis is routinely diagnosed through a clinical examination. Blood and lymph are fluid connective tissues. A histologist examines a tissue slide and observes many fibers tightly packed together in a parallel arrangement. It derives its name from the Latin reticulus, which means little net.. This is a factor contributing to the very slow healing of cartilaginous tissues.

This page titled 3.4: Connective Tissue is shared under a CC BY license and was authored, remixed, and/or curated by Whitney Menefee, Julie Jenks, Chiara Mazzasette, & Kim-Leiloni Nguyen (ASCCC Open Educational Resources Initiative) . The first connective tissue to develop in the embryo is mesenchyme, the stem cell line from which all connective tissues are later derived. Bones rigid extracellular matrix contains mostly collagen fibers embedded in a mineralized ground substance containing hydroxyapatite, a form of calcium phosphate. Transcribed Image Text: adipose collagen, reticular, elastic that convey (s) tissue fluid and strengthen (s) organs is/are that store (s) fat and protect (s) organs is/are that attach (es) muscles and bones is/are dense connective tissue collagen and a few elastic Pearson connective tissue areolar matrix includes ground substance and the These fibers hold connective tissues together, even during the movement of the body. epithelia are supplied by nerve fibers. Q. What are the 3 types of connective tissue fibers? The main property of elastin is that after being stretched or compressed, it will return to its original shape. The histology of transverse tissue from long bone shows a typical arrangement of osteocytes in concentric circles around a central canal. 1999-2023, Rice University. As you toss the ball high in the air, a burning pain shoots across your wrist and you drop the tennis racket. Elastic cartilage contains elastic fibers as well as collagen and proteoglycans. With proper rest and managed care, you will be back on the court to hit that slice-spin serve over the net. It stores fat for energy and provides insulation. The mesenchymal cell is a multipotent adult stem cell. The ligaments in the vocal folds and between the vertebrae in the vertebral column are elastic. Exercise 5: classification of tissues Flashcards | Quizlet . Under membranes there can be several different layers of connective tissues, known as fascia, that function to connect internal structures to the rest of the body. Blood is a fluid connective tissue, a variety of specialized cells that circulate in a watery fluid containing salts, nutrients, and dissolved proteins in a liquid extracellular matrix. Under the microscope, tissue samples appear clear. Severe cases of tendinitis can even tear loose a tendon. Watch this animation to learn more about tendonitis, a painful condition caused by swollen or injured tendons. Reticular tissue is a mesh-like, supportive framework for soft organs such as lymphatic tissue, the spleen, and the liver (Figure \(\PageIndex{4}\)). The formed elements circulating in blood are all derived from hematopoietic stem cells located in bone marrow ([link]). Fibroblasts produce this fibrous tissue. The major types of connective tissue are connective tissue proper, supportive tissue, and fluid tissue. This is probably ________. Except where otherwise noted, textbooks on this site or it can form "ropes" (tendons and ligaments) of incredible strength.
