Study Notes
Nervous Tissue and Connective Tissue
- Nervous tissue is primarily composed of neurons and does not predominantly consist of collagen fibers.
- Connective tissue typically contains a significant amount of matrix and collagen fibers, providing strength and support to various structures.
Epithelial Tissue Characteristics
- Dense microvilli in simple columnar epithelium enhance absorption in the digestive tract.
- Simple squamous epithelium forms the walls of air sacs in the lungs for efficient gas exchange.
- Stratified squamous epithelium features multiple layers with cuboidal basal cells and flat surface cells, offering protection against abrasion.
Tissue Repair and Inflammation
- Inflammation initiates tissue repair by causing capillaries to dilate and increase permeability, allowing immune cells to reach the injured area.
Types of Glandular Epithelia
- Goblet cells in pseudostratified ciliated columnar epithelium secrete mucus, aiding in protection and lubrication.
- Merocrine glands secrete substances without altering the cell structure, in contrast to cell rupture found in other gland types.
Muscle and Connective Tissue Features
- Smooth muscle cells possess a central nucleus and lack striations, displaying a unique structure suited for involuntary movements.
- Fibrocartilage serves as shock-absorbing pads between vertebrae, characterized by high tensile strength and the presence of collagen fibers.
Extra Facts on Bone and Cartilage
- Bone tissue includes lacunae, calcium salts, and blood vessels, differentiating it from other tissues.
- Hyaline cartilage is distinct for having collagen fibers that are typically not visible, offering a smooth surface.
Function and Structure of Various Tissues
- Adipose tissue functions primarily in nutrient storage, while also providing insulation and padding for organs.
- Endocrine glands, such as the thyroid, release hormones directly into the bloodstream, without ducts.
Histological Insights
- Epithelial tissues display polarity, having distinct apical and basal surfaces crucial for their functionality.
- Transitional epithelium can morphologically resemble either stratified squamous or cuboidal epithelium depending on the bladder's state.
Regeneration and Healing
- Cartilage heals slower than bone due to its reduced blood supply, leading to more gradual recovery from injuries.
- Edema, or swelling, occurs when areolar tissue absorbs excess fluid during inflammation, contributing to tissue homeostasis.
Miscellaneous Tissue Facts
- Intercalated discs, found in cardiac muscle, are essential for cell cohesion and communication.
- Elastic cartilage provides structural integrity and adaptability, found in areas like the external ear and large arterial walls.
