Connective, Muscle, and Nervous Tissue Connective Tissue All connective tissues have three components 1) Ground Substance- 2) Extracellular Protein Fibers —3 types (produced by fibroblasts) a. 1 + 2 = Extracellular Matrix. (Proteins are unpolymerized in fluid connective tissues such as blood) 3) Specialized Cells —Multiple cell types in connective tissues Specifics about Components 1) Ground Substance —Semi viscous fluid containing proteoglycans and glycoproteins found in interstitial space. Surrounds cells and fibers. Consistency from watery to jello 2) Extracellular Protein Fibers a. Collagen Fibers —Common, formed like a rope with protein subunits wound together. Strong along axis of fiber. Common in tendons and ligaments. b. Reticular Fibers —Form a network or web of fibers (stroma). Resists forces from all directions. Hold parenchyma cells (functional cells of an organ) in position. Maintains relative positions. c. Elastic Fibers —Made of the protein elastin. Filaments are wavy and stretch. Found in ligaments between vertebrae and in large artery walls (allow recoil after stretch). 3) Specialized Cells ---ex. RBCs, lymphocytes, chondrocytes, osteocytes, etc… Two basic classes of connective tissue 1) Connective Tissue Proper a. Loose (areolar) Connective Tissue b. Dense Connective Tissues i. Regular—2D fiber arrangement ii. Irregular—3D fiber arrangement 1. Collagenous 2. Elastic c. Reticular connective tissue d. Adipose connective tissue i. White fat ii. Brown fat

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
