Study Notes
Tissue Types and Structures
- The external ear shape is supported by elastic cartilage.
- Organized cellular groups with a common function are called tissues.
- Epithelial tissue functions include controlling permeability, protection, and absorption, but not energy storage.
- Mucous membranes line cavities that open to the environment.
- Basic epithelial cell shapes include columnar, cuboidal, and squamous; stratified is not a shape but a layering.
- Muscle tissue is not classified as connective tissue.
Connective Tissue Characteristics
- Nervous tissue conducts electrical impulses.
- Connective tissue comprises ground substance, fibers, and cells; matrix refers to fibers and ground substance.
- Collagen fibers provide tensile strength to connective tissue.
Types of Epithelia
- Pseudostratified columnar epithelium has cells touching the basement membrane, creating an appearance of multiple layers.
- Transitional epithelium lines the urinary bladder, allowing for stretching.
- Simple cuboidal epithelium is associated with secretion and absorption.
Muscle Tissue
- Smooth muscle tissue lacks striations and is involuntary.
- Striations are present in skeletal and cardiac muscle tissues.
Tissue Repair and Inflammation
- The initial step in tissue repair involves the formation of granulation tissue.
- Redness and heat in inflamed tissue result from local vasodilation (blood vessel dilation).
Epithelial Characteristics
- Stratified epithelia protect against abrasion, while simple epithelia often do not provide impermeable barriers.
- Epithelial tissue has a basement membrane and exhibits polarity, featuring a free surface and a basal surface.
Miscellaneous Facts
- Smooth muscle cells contain central nuclei but lack striations.
- Most connective tissues possess regenerative capacity, while most epithelial tissues do not.
