Multiple Choice
Which of the following is an example of a synchondrosis joint?

Epiphyseal plate in growing long bones
B
Intervertebral discs
C
Pubic symphysis
D
Sutures of the skull
Verified step by step guidance

Understand the definition of a synchondrosis joint: A synchondrosis is a type of cartilaginous joint where bones are joined by hyaline cartilage, allowing very little movement.
Identify the characteristics of each option: The epiphyseal plate is a temporary cartilaginous joint found in growing long bones, composed of hyaline cartilage.
Consider the intervertebral discs: These are fibrocartilaginous joints, not synchondroses, as they contain fibrocartilage and allow slight movement between vertebrae.
Evaluate the pubic symphysis: This is a secondary cartilaginous joint (symphysis) made of fibrocartilage, allowing limited movement, not a synchondrosis.
Examine the sutures of the skull: These are fibrous joints, not cartilaginous, and are immovable, thus not fitting the definition of a synchondrosis.
