Study Notes
Tissue Types
- Primary tissue types include muscle, nervous, epithelium, and connective, with bone classified as a subset of connective tissue.
- Epithelial tissue is predominantly composed of cells, not matrices, which are arranged in layers for functions like absorption.
Epithelial Characteristics
- Simple epithelium contains a single layer of cells resting on a basement membrane.
- Epithelial cells can exhibit various shapes: cuboidal, columnar, and squamous.
- They do not secrete a ground substance; instead, they primarily consist of closely packed cells.
Fluid Imbalance
- Hypotonic hydration: total body water elevated, ECF remains hypotonic.
- Volume excess: total body water elevated, ECF remains isotonic.
- Hypovolemia: total body water reduced, ECF stays isotonic.
- Dehydration: total body water reduced, ECF becomes hypertonic.
Buffers and pH
- Buffers are mechanisms that resist changes in pH, important for maintaining physiological balance.
Connective Tissues
- Cartilage is a relatively stiff connective tissue characterized by a rubbery matrix.
- Connective tissues are categorized into two broad classes: fibrous (loose and dense) and specialized (like cartilage and bone).
Extracellular Fluid
- Extracellular fluid compartments encompass various fluids but require specific identification.
Excitable Tissues
- Tissues responding to stimuli by altering membrane potential are classified as excitable tissues, mainly encompassing nervous and muscular tissues.
Cell Growth Types
- Hyperplasia: increase in cell numbers via mitosis, common in childhood development.
- Hypertrophy: increase in cell size, prevalent in muscle and adipose tissues.
- Neoplasia: formation of tumors with abnormal, non-functional cells.
Epithelial Tissue Types
- Epithelia are surfaces composed of layers of densely packed cells.
- Cutaneous, mucous, and serous refer to different types of epithelial tissues, each with distinct functions and locations.
- Stratified epithelium has multiple layers, with stratified squamous epithelium being the most widespread type.
Importance of pH Regulation
- Maintaining pH within normal limits is crucial, as deviations can disrupt macromolecule structure and function, potentially halting metabolic processes.
