Chapter 11, Problem 1.1BGL

Summary Introduction

Introduction: Joints are the region where two or more bones meet. Joints also connect a bone with cartilage or tooth. Joints are mobile that allows movement of bone. Structural and functional classification of joints depends on the connective tissue that forms the joints as well as whether a synovial cavity is present between them or not.

Answer to Problem 1.1BGL

Fig.11.1 entitled “structural classification of joints” given in the textbook follows the category of structural and functional joints as given in Fig.1:

Fig.1: Structural and functional joints

Explanation of Solution

Fibrous joints: This joint does not have synovial cavity but connected by dense fibrous connective tissue and collagen fibers.

Cartilaginous joints: This joint does not have a synovial cavity but have hyaline cartilage or fibrocartilage that connects the bone.

Synovial joints: This joint has a small synovial cavity that permits greater movement of joints.

Synarthrosis: This is an immovable joint such as present between skull bones and teeth sockets.

Amphiarthrosis: This joint has limited movement ability. It is present between the adjacent vertebrae.

Diarthrosis: This joint is freely movable. It is also known as synovial joints that have synovial fluids.
