Study Notes
Tissue Types and Characteristics
- Four main tissue categories: muscle tissue, neural tissue, connective tissue, and epithelial tissue. Osseous tissue is not one of the primary categories.
- Epithelial tissue features an apical (top) and a basal (bottom) surface, distinguishing it from other tissue types.
- Key characteristics of epithelia include attachment, avascularity, regeneration, and polarity; they lack an extracellular matrix.
Epithelial Tissue Functions
- Epithelial cells specialized for absorption typically possess microvilli at their free surface to increase surface area.
- Epithelia are connected to underlying connective tissue through a basement membrane, crucial for nutrient support and attachment.
- Transitional epithelium lines the urinary bladder, allowing for distension and contraction.
Specific Types and Locations of Epithelia
- Pseudostratified columnar epithelium is found lining the trachea, aiding in respiratory function.
- Squamous cells, characterized by their flat and thin shape, form a simple squamous epithelium that lines body cavities and blood vessels.
Connective Tissue Classification
- Connective tissue proper includes areolar connective tissue, adipose tissue, and dense irregular connective tissue.
- Fibroblasts are the cells responsible for producing protein fibers in areolar connective tissue, maintaining its structure.
Types of Connective Tissues
- Blood is classified as connective tissue, containing erythrocytes (red blood cells), leukocytes (white blood cells), and platelets.
- The viscous material between cells in areolar connective tissue is known as ground substance, providing cushioning and support.
Muscle Tissue Features
- Intercalated discs are unique to cardiac muscle tissue, facilitating synchronized contraction.
- Smooth muscle tissue is characterized by the absence of striations, allowing for involuntary control of various organs.
Neural Tissue
- Neural tissue is specialized for conducting electrical impulses, critical for signaling within the body.
- Neuroglia (glial cells) support, protect, and nourish neurons, playing a vital role in maintaining nervous system health.
Blood Composition
- Plasma is the liquid component of blood, making up about half of its volume, while formed elements include cells and cell fragments.
- The three types of protein fibers in connective tissue are collagen, reticular, and elastic, contributing to tissue strength and flexibility.
Osseous Tissue
- Osseous tissue, commonly known as bone, is characterized by its solid matrix and functions in supporting the body structure.
General Connective Tissue Functions
- Loose connective tissue supports epithelia and anchors blood vessels and nerves, providing a flexible connective architecture.
- Dense connective tissue types include tendons and ligaments, with collagen being the dominant fiber type.
Glandular Secretion Types
- Glands can release products through various mechanisms such as holocrine, where cells burst to release their substance, and apocrine, showing partial cell loss during secretion.
