Textbook Question

Match the types of joints to the descriptions that apply to them.
a. Fibrous joints
b. Cartilaginous joints
c. Synovial joints
9. Shoulder, hip, knee, and elbow joints

Verified step by step guidance

Understand the three types of joints: Fibrous joints are immovable and connected by dense connective tissue; Cartilaginous joints allow limited movement and are connected by cartilage; Synovial joints are freely movable and have a fluid-filled cavity.

Identify the anatomical locations mentioned in the problem: shoulder, hip, knee, and elbow joints.

Recall that these joints are highly movable and are involved in a wide range of motion, which is characteristic of synovial joints.

Match the descriptions of synovial joints to the anatomical locations provided, as these joints are designed for mobility and are supported by ligaments, cartilage, and synovial fluid.

Conclude that the shoulder, hip, knee, and elbow joints are examples of synovial joints based on their structure and function.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Fibrous Joints

Fibrous joints are connected by dense connective tissue and are typically immovable. They include structures like sutures in the skull, where bones are tightly bound together, providing stability and protection. These joints do not have a joint cavity and are classified as synarthroses, meaning they allow little to no movement.

Cartilaginous Joints

Cartilaginous joints are connected by cartilage and allow for limited movement. They can be classified into two types: synchondroses, which are immovable, and symphyses, which allow slight movement. An example is the intervertebral discs in the spine, which provide cushioning and flexibility while maintaining stability.

Synovial Joints

Synovial joints are the most movable type of joint in the body, characterized by a fluid-filled joint cavity. They include joints like the shoulder, hip, knee, and elbow, allowing for a wide range of motion. These joints are surrounded by a synovial membrane that secretes synovial fluid, lubricating the joint and reducing friction during movement.
