Section 1

Question Answer
What are four main types of tissue?Epithelial, Connective, Muscle & Nerve
Characteristics of Connective tissue?Abundant Intercellular matrix, wide range of vascularity
what are 4 subtypes of Connective tissue?Connective tissue proper, blood, bone & cartilage
What are 3 components of Connective tissue?Ground substance (composed of interstitial fluid), Fibers, Cells
Ground substance + Fibers =Matrix

Section 2

Question Answer
characteristics of Collagenous fibers:white, thick, tough & strong, high tensile strength, stains pink on slides
characteristics of Elastic fibers:Yellow, thin, elastic, can stretch & recoil, stains dark
characteristics of Reticular fibers:branched & jagged in appearance, supportive network for other cells, stains very dark
which is the most abundant fiber in connective tissue?Collagen fibers
Loose fiber arrangement:few fibers and many cells
Dense fiber arrangement:many fibers and few cells
