• What is the description of simple squamous epithelium?


  A single layer of flat cells resembling a tiled floor from the apical surface.
• What is the function of simple squamous epithelium?

  Facilitates filtration and diffusion, and is involved in secretion in serous membranes.
• What is the description of simple cuboidal epithelium?

  A single layer of cube-shaped cells with a round, centrally located nucleus.
• What is the primary function of simple cuboidal epithelium?

  Primarily involved in secretion and absorption.
• What is the description of nonciliated simple columnar epithelium?

  A single layer of column-like cells with oval nuclei near the base, containing microvilli and goblet cells.
• What are the functions of nonciliated simple columnar epithelium?

  Secretion and absorption; mucus lubricates and protects linings of various tracts.
• What is the description of ciliated simple columnar epithelium?

  A single layer of column-like cells with oval nuclei near the base, often interspersed with goblet cells.
• What is the function of ciliated simple columnar epithelium?

  Cilia move mucus and foreign particles toward the throat and help move oocytes through uterine tubes.
• What is the description of pseudostratified columnar epithelium?

  Appears multilayered due to varying nucleus levels but consists of a single layer of cells attached to the basement membrane.
• What are the functions of pseudostratified columnar epithelium?

  The ciliated type secretes mucus and moves it away from the respiratory tract; the nonciliated type functions in absorption and protection.
• What is the description of stratified squamous epithelium?

  Multiple layers of cells with the apical layer and several layers beneath being squamous.
• What is the function of stratified squamous epithelium?

  Protection against abrasion, water loss, UV radiation, and microbes.
• What is the description of stratified cuboidal epithelium?

  Multiple layers with apical cells that are cube-shaped.
• What is the function of stratified cuboidal epithelium?

  Provides protection and limited secretion and absorption.
• What is the description of stratified columnar epithelium?

  Basal layers consist of shorter, irregularly shaped cells; only the apical layer has columnar cells.
• What is the function of stratified columnar epithelium?

  Protection and secretion.
• What is the description of transitional epithelium?

  Variable appearance; in a relaxed state, resembles stratified cuboidal epithelium with rounded apical cells.
• What is the function of transitional epithelium?

  Allows stretching of urinary organs and maintains a protective lining while holding varying amounts of fluid.
• What is the description of endocrine glands?

  Endocrine glands secrete hormones directly into the bloodstream without using ducts.
• What is the function of endocrine glands?

  Hormones from endocrine glands regulate various metabolic and physiological activities to maintain homeostasis.
• What are examples of endocrine glands?

  Pituitary gland, pineal gland, thyroid gland, parathyroid glands, adrenal glands, pancreas, ovaries, testes, thymus.
• What is the description of exocrine glands?

  Exocrine glands release their secretions into ducts that lead to body surfaces or cavities.
• What is the function of exocrine glands?

  They produce substances like sweat, saliva, digestive enzymes, and other secretions.
• What is the description of mesenchyme?


  Mesenchyme consists of irregularly shaped cells in a semifluid ground substance with delicate reticular fibers.
• Where is mesenchyme found?

  Found in the developing embryo and in some adult connective tissues, particularly around blood vessels.
• What is the function of mesenchyme?


  It is the precursor to almost all other types of connective tissues.
• What is the description of mucous connective tissue?

  Contains widely scattered fibroblasts in a viscous, jelly-like ground substance with fine collagen fibers.
• Where is mucous connective tissue primarily found?

  Found primarily in the umbilical cord of the fetus.
• What is the function of mucous connective tissue?

  Provides support and acts as a cushioning material.
• What is the description of areolar connective tissue?

  Composed of a semifluid ground substance with randomly arranged fibers and various cells.
• Where is areolar connective tissue found?

  Widely distributed throughout the body, including under the skin, around organs, and in mucous membranes.
• What is the function of areolar connective tissue?

  Provides strength, elasticity, and support; often considered the "packing material" of the body.
• What is the description of adipose tissue?

  Composed of adipocytes that store triglycerides in a large central droplet.
• Where is adipose tissue found?

  Found in the subcutaneous layer, around organs, in yellow bone marrow, and around joints.
• What is the function of adipose tissue?

  Stores energy, provides insulation, supports and protects organs.
• What is the description of reticular connective tissue?

  Characterized by a fine network of reticular fibers and reticular cells.
• Where is reticular connective tissue found?

  Forms the stroma of organs such as the liver, spleen, and lymph nodes.
• What is the function of reticular connective tissue?

  Supports the structure of organs, filters out worn-out cells, and helps in immune responses.
• What is the description of hyaline cartilage?

  Has a gel-like ground substance with fine collagen fibers that are not visible with ordinary staining.
• Where is hyaline cartilage found?

  Found at the ends of long bones, the anterior ends of ribs, the nose, and the trachea.
