This document is a set of detailed notes on connective tissue, likely from a histology or anatomy course. It covers the origin, types, and functions of connective tissue, including fibrous, fatty, and hard connective tissue. The notes explain the roles of fibroblasts, collagen, elastin, and reticulin, as well as the differences between white and brown adipose tissue. It also discusses cartilage types (hyaline, elastic, fibrous) and their locations, along with the structure and function of smooth, skeletal, and cardiac muscle. The tone is academic and precise, aimed at helping students understand the histological features and physiological roles of connective tissues and muscles.

Fibroblasts 2. Fat cells 3. Chondroblasts Some are derived from the haematopoetic stem cell line: . Monocytes . Macrophages . Lymphocytes . Mast cells Rene Fibroblasts. Adipose cells Principle fibres: Collagen Elastin (stains pink with H&E) Reticulin Jelly-like complexes (appears as white spaces, do not stain with H&E): 1 glycosaminoglycans (GAGs) © Proteoglycans Invisible fibres: 3 Laminin Fribroneetin Can be loose irregular (when few visible fibres that are randomly orientated are observed) e.g. in arterial adventitia 2 or dense irregular (when connective tissue contains large numbers of fibres that are arranged in long parallel bundles) e.g. in tendons 1/16
