Textbook Question

The joint between adjacent vertebral bodies is a
(a) Syndesmosis
(b) Symphysis
(c) Synchondrosis
(d) Synostosis.

Verified step by step guidance

Understand the types of joints listed in the problem: syndesmosis, symphysis, synchondrosis, and synostosis. These are all classifications of joints based on their structure and function.

Recall that a syndesmosis is a fibrous joint where bones are connected by ligaments or interosseous membranes, allowing slight movement. Examples include the distal tibiofibular joint.

Recognize that a symphysis is a cartilaginous joint where bones are connected by fibrocartilage, allowing limited movement. Examples include the pubic symphysis and the intervertebral discs between vertebral bodies.

Understand that a synchondrosis is a cartilaginous joint where bones are connected by hyaline cartilage, typically allowing little to no movement. Examples include the epiphyseal plates in growing bones.

Learn that a synostosis is a bony joint where two bones fuse together, eliminating movement. Examples include the fusion of cranial sutures in adults. Based on this information, identify the correct classification for the joint between adjacent vertebral bodies.

Key Concepts

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

Types of Joints

Joints are classified based on their structure and function. The main types include fibrous, cartilaginous, and synovial joints. Each type has distinct characteristics that determine its movement capabilities and stability. Understanding these classifications is essential for identifying the nature of the joint between vertebral bodies.

Symphysis

A symphysis is a type of cartilaginous joint where the bones are joined by a pad of fibrocartilage, allowing for limited movement. This type of joint is found in areas such as the pubic symphysis and the intervertebral discs, providing both stability and slight flexibility, which is crucial for the spine's function.

Vertebral Bodies

Vertebral bodies are the main structural components of the vertebrae in the spine. They are cylindrical in shape and stacked on top of one another, separated by intervertebral discs. Understanding the anatomy and function of vertebral bodies is key to recognizing how they articulate and the type of joint formed between them.
