Study Notes
Goblet Cells
- Column-shaped cells that secrete mucus to protect mucous membranes, particularly in the respiratory tract.
Epithelial Tissue Types
-
Simple Columnar Epithelium: Composed of tall cells with an oval nucleus. Found in the respiratory tract and reproductive organs.
-
Ciliated Columnar Epithelium: Features cilia that move mucus and trapped particles upward (mucociliary escalator) to protect lungs.
-
Pseudostratified Ciliated Columnar Epithelium: Appears layered but is a single layer with nuclei at varying levels. Lines the nasal cavity, aiding in air filtration.
-
Stratified Squamous Epithelium: Most common stratified type, offering protection against stress and infection, and regenerates quickly. Can be keratinized (skin) or non-keratinized (oral cavity, esophagus).
-
Stratified Cuboidal Epithelium: Less common, typically found in ducts of larger glands; provides protection and limited secretion/absorption.
-
Stratified Columnar Epithelium: Contains several cell layers; found in male urethra and some gland ducts, responsible for protection and secretion.
Connective Tissues
-
Characterized by an extracellular matrix composed of protein fibers (collagen, elastin) and ground substance, providing support and filling spaces.
-
Types of Connective Tissue:
-
Connective Tissue Proper:
- Loose Connective Tissue: Contains loosely packed fibers; provides elasticity.
- Dense Connective Tissue: Tightly packed fibers; includes white fibrous tissue, tendons, ligaments, and reticular tissues.
-
Supportive Connective Tissue:
- Cartilage: Semi-rigid and flexible; types include hyaline (smooth, glass-like), elastic (flexible), and calcified (hardened).
- Bone: Rigid, with matrix of calcium and phosphate salts; includes different types (membrane, cartilage, sesamoid, visceral).
-
Fluid Connective Tissue:
- Blood: Contains plasma, blood cells (RBCs, WBCs, platelets), and nutrients.
- Lymph: Similar to plasma but contains fewer proteins; aids in nutrient transport and waste removal.
-
Cellular Components
-
Adipose Tissue: Stores fat, providing energy reserves, shock absorption, and heat retention; located in skin, kidneys, and bone marrow.
-
Fibroblast: Principal cells in areolar tissue responsible for protein production (collagen and elastin).
-
Macrophage: Phagocytic cells that ingest pathogens and foreign substances.
-
Mast Cells: Produce histamine for allergic responses.
-
Plasma Cells: Produce antibodies for immune response.
Blood Components
- Plasma: The liquid matrix of blood; includes electrolyte, hormones, nutrients, and proteins.
- Serum Albumin: Maintains blood osmotic pressure, transports hormones and fatty acids, and acts as a buffer.
- Serum Globulin: Involved in immune response and lipid transport.
- Fibrinogen: Essential for blood clotting; converts to fibrin to form clots and prevent bleeding.
Glucose Metabolism
- Glucose is absorbed in the liver; excess is converted to glycogen (stored energy) by insulin.
