Textbook Question

Match the types of joints to the descriptions that apply to them.
a. Fibrous joints
b. Cartilaginous joints
c. Synovial joints
2. Types are sutures and syndesmoses

Verified step by step guidance

Understand the three types of joints: Fibrous joints, Cartilaginous joints, and Synovial joints. Fibrous joints are connected by dense connective tissue, cartilaginous joints are connected by cartilage, and synovial joints have a fluid-filled cavity.

Identify the specific types of fibrous joints: Sutures and syndesmoses. Sutures are immovable joints found in the skull, while syndesmoses are slightly movable joints connected by ligaments.

Determine whether sutures and syndesmoses fit the description of fibrous joints. Since they are connected by dense connective tissue and lack a joint cavity, they are classified as fibrous joints.

Review the characteristics of cartilaginous joints and synovial joints to confirm that sutures and syndesmoses do not belong to these categories. Cartilaginous joints involve cartilage (e.g., intervertebral discs), and synovial joints involve a fluid-filled cavity (e.g., knee joint).

Conclude that the correct match for the types of joints described (sutures and syndesmoses) is 'a. Fibrous joints.'

Key Concepts

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

Fibrous Joints

Fibrous joints are connections between bones that are held together by dense connective tissue. They are typically immovable and include structures such as sutures found in the skull and syndesmoses, which allow for slight movement. These joints provide stability and strength to the skeletal system.

Cartilaginous Joints

Cartilaginous joints are joints where the bones are connected by cartilage, allowing for more movement than fibrous joints but less than synovial joints. They can be classified into two types: synchondroses, which are immovable, and symphyses, which allow for slight movement. An example is the pubic symphysis, which provides flexibility during childbirth.

Synovial Joints

Synovial joints are the most movable type of joint in the body, characterized by a fluid-filled joint cavity. They allow for a wide range of motion and include various types such as hinge, ball-and-socket, and pivot joints. The presence of synovial fluid reduces friction and nourishes the cartilage, facilitating smooth movement.
