Connective, muscle and nervous tissues
This document discusses the three main types of tissues in the body: connective, muscle, and nervous tissue. It provides examples of different connective tissues, including both solid tissues like cartilage, bone, tendons, and ligaments, as well as fluid tissues like lymph and blood. Connective tissues function to provide protection, support, compartmentalization, and binding organs together. Within connective tissue, there are loose connective tissues like areolar tissue composed of collagenous, elastic, and reticular fibers, as well as adipose tissue which functions for insulation. Dense connective tissues have interwoven bundles and form tendons, aponeuroses, and ligaments. Cartilage is also discussed, including the different

Connective, muscle and nervous tissues
- 1. The tissue levelof organization Connective, Muscle, and Nervous Tissues
- 3. Examples of connectivetissue • Solid – Cartilage – Bone – Tendons – Ligaments – Fibrous tissues • Fluid – Lymph – Blood
- 4. Connective tissue functions •Protection • Support • Separation / compartmentalization • Bind organs together • Energy storage

- 9. Loose connective tissue •Loosely woven fibers produced by fibroblasts • Three types of fibers – Collagenous (collagen): tough, parallel bundles – Elastic (elastin): smaller, still strong, can stretch – Reticular: v. thin branching strong support
- 10.
- 11. Adipose tissue • Fat •Found within loose connective – Sub cutaneous = adipose + areolar • Insulation and protection – Around kidneys, heart surface, joints, behind eye
- 12.
- 13. Dense connective tissue •Interwoven fibrous bundles • Main components of tendons, aponeuroses and ligaments – Tendons connect muscles to bone – Aponeuroses are sheet like tendons – Ligaments connect bone to bone
- 15. Cartilage • Strong andresilient • Avascular • Growth • Chondrocytes divide • Chondroblasts become chondrocytes
- 16. Types of cartilage •Hyaline, -most abundant in body – Shock absorption – Embryonic skeleton – At ends of long bones (joints) – Ribs, nose, larynx, trachea, bronchi, bronchioles • Fibrocartilage – V. strong and rigid – Symphysis pubis and between vertebrae • Elastic – stretches and retains shape – Epiglottis, external ear, eustachian tubes
