Final answer:
An example of a slightly movable joint is the cartilaginous joint between the vertebrae. The intervertebral discs in this joint allow for a limited amount of movement between the vertebrae.
Step-by-step explanation:
An example of a slightly movable joint (amphiarthrodial) is the cartilaginous joint that unites the bodies of adjacent vertebrae. The intervertebral discs, which are made of fibrocartilage, fill the gap between the vertebrae and allow for a limited amount of movement between them. These small movements can sum together along the length of the vertebral column to provide for large ranges of body movements.
