A
hinge
B
fibrous
C
synovial
D
cartilaginous
Verified step by step guidance
1
Step 1: Begin by understanding the term 'symphysis.' A symphysis is a type of joint where two bones are connected by fibrocartilage, allowing limited movement. This is important for identifying the correct joint type.
Step 2: Review the characteristics of the different types of joints listed in the options: hinge, fibrous, synovial, and cartilaginous. For example, hinge joints allow movement in one plane (e.g., elbow), fibrous joints are immovable (e.g., sutures in the skull), synovial joints are freely movable (e.g., shoulder), and cartilaginous joints allow limited movement and are connected by cartilage.
Step 3: Compare the definition of a symphysis to the characteristics of each joint type. Since a symphysis involves fibrocartilage and limited movement, it aligns with the definition of a cartilaginous joint.
Step 4: Recall examples of symphyses in the human body, such as the pubic symphysis or intervertebral discs, which are both cartilaginous joints. This reinforces the correct classification.
Step 5: Conclude that the correct answer is 'cartilaginous,' as symphyses are a specific type of cartilaginous joint characterized by fibrocartilage and limited movement.
