  • What are the main types of epithelial tissues?

    Simplified types: squamous, cuboidal, columnar; can be simple (one layer) or stratified (multiple layers).

  • What defines connective tissue proper?

    Connective tissue proper includes loose and dense connective tissues that support and bind other tissues.

  • Name the two main categories of connective tissues.

    Connective tissue proper and specialized connective tissues like cartilage, bone, and blood.

  • What are the characteristics of cartilage connective tissue?

    Cartilage is a flexible, avascular connective tissue with chondrocytes in a gel-like matrix.

  • What is the function of epithelial tissue?

    To cover body surfaces, line cavities, and form glands for protection, absorption, and secretion.

  • Describe simple squamous epithelium.

    A single layer of flat cells allowing diffusion and filtration, found in lungs and blood vessels.

  • What is loose connective tissue?

    Connective tissue proper with loosely arranged fibers providing cushioning and support.

  • What distinguishes dense connective tissue from loose connective tissue?

    Dense connective tissue has tightly packed collagen fibers for strength, found in tendons and ligaments.

  • What cells are found in connective tissue proper?

    Fibroblasts, macrophages, mast cells, and adipocytes.

  • What is the extracellular matrix in connective tissue composed of?

    Protein fibers (collagen, elastin) and ground substance (fluid, proteoglycans).

  • What is the role of chondrocytes in cartilage?

    They produce and maintain the cartilage matrix.

  • Where is stratified squamous epithelium found?

    In areas subject to abrasion like skin, mouth, and esophagus.

  • What is the difference between hyaline and elastic cartilage?

    Hyaline cartilage is firm and glassy; elastic cartilage is flexible due to elastic fibers.

  • What is the function of dense regular connective tissue?

    Provides strong attachment in one direction, found in tendons and ligaments.

  • What type of epithelial tissue lines the respiratory tract?

    Pseudostratified ciliated columnar epithelium.

  • What is adipose tissue?

    A type of loose connective tissue specialized in storing fat.

  • What is the function of connective tissue proper?

    To connect, support, protect, and insulate organs and tissues.

  • What is fibrocartilage and where is it found?

    A tough cartilage with dense collagen fibers, found in intervertebral discs and menisci.

  • What is the basement membrane in epithelial tissue?

    A thin layer that anchors epithelium to underlying connective tissue.

  • What are the main functions of cartilage connective tissue?

    Support, flexibility, and cushioning in joints and structures.
