Study Notes
Muscle Tissue
- Smooth Muscle: Involuntary tissue found in walls of hollow organs; facilitates movement.
- Cardiac Muscle: Found exclusively in the heart; features intercalated disks for synchronized contractions.
- Skeletal Muscle: Voluntary muscle with striations; associated with movement of skeleton.
Nervous Tissue
- Multipolar Neuron: A type of neuron with multiple extensions; responsible for signal transmission.
- Neuroglial Cell: Supportive cells for neurons, crucial for maintaining the nervous system.
Epithelial Tissue
- Non-Keratinized Stratified Squamous Epithelium: Lines esophagus; allows for durable yet flexible surfaces.
- Keratinized Stratified Squamous Epithelium: Forms the epidermis; provides protection through keratin.
- Simple Squamous Epithelium: Lines blood vessels and alveoli; facilitates diffusion and filtration.
- Simple Cuboidal Epithelium: Located in glands and kidney tubules; involved in secretion and absorption.
- Simple Columnar Epithelium: Lines most of the digestive tract; involved in absorption and secretion.
- Pseudostratified Ciliated Columnar Epithelium: Lines the trachea and bronchi; aids in mucus transport.
- Transitional Epithelium: Lines the urinary bladder; allows for expansion and contraction.
Connective Tissue
- Areolar Connective Tissue: Provides support and elasticity; found beneath the skin and surrounding organs.
- Dense Regular Connective Tissue: Forms tendons and ligaments; provides strength in one direction.
- Adipose Connective Tissue: Stores fat; insulation and energy reservoir.
- Compact Bone: Structural tissue of bones; organized in osteons for strength.
- Blood Connective Tissue: Composed of erythrocytes (red blood cells) and leukocytes (white blood cells).
- Cartilage: Includes elastic cartilage (supports external ear and epiglottis) and hyaline cartilage (provides support in trachea and larynx).
Specific Structures
- Basement Membrane: Layer found beneath epithelial tissues for support and filtration.
- Apical Surface: Surface of epithelial cells facing the lumen or external environment.
- Cilia and Goblet Cells: Structures found in certain epithelial tissues; cilia aid in movement, while goblet cells secrete mucus.
- Fibroblasts: Cells responsible for synthesizing extracellular matrix and collagen in connective tissues.
Key Locations of Tissues
- Epidermis: Outer layer of skin composed of keratinized stratified squamous epithelium.
- Urinary Bladder and Ureters: Lined by transitional epithelium allowing for flexibility.
- Digestive Tract: Mostly lined by simple columnar epithelium; specialized regions may have different epithelial types (simple cuboidal, stratified cuboidal).
- Hypodermis: Contains adipose tissue for insulation and cushioning.
Cellular Components
- Osteon: Fundamental unit of compact bone.
- Central Canal: Contains blood vessels and nerves in bone.
- Canaliculi: Small channels in bone that allow for nutrient exchange.
- Lacuna: Spaces that house osteocytes or chondrocytes in bone and cartilage.
