No, it is between the clavicle and manubrium
An articulation between a vertebrae and a rib
The articulation between the first costal cartilage and the manubrium is classified as a synchondrosis joint. This type of joint is characterized by the presence of hyaline cartilage that allows for slight movement, primarily during respiration. The first rib's connection to the manubrium is a cartilaginous joint that provides stability while allowing for some flexibility.
The 1st rib articulates primarily with the first thoracic vertebra at the costovertebral joint. Additionally, it forms a joint with the manubrium of the sternum at the sternocostal joint. This rib is unique in its anatomy and plays a critical role in the thoracic structure and function.
The manubrium is united to the body of the sternum either by an amphiarthrodial joint-a piece of fibrocartilage connecting the segments-or by a diarthrodial joint, in which the articular surface of each bone is clothed with a lamina of cartilage.
A suture/synarthrosis/synovial is the group of joint terms listed above that is not correctly matched.
Types of cartiliginous joints: Synchondrosis Symphysis Synchondrosis joint has bands of hyaline cartilage which unite bones and an epiphyseal plate (temporary). For example between manubrium and first rib (synarthrotic). Symphysis joint has a pad of fibrocartilage between bones. For example the pubis symphysis and the joint between bodies of vertebrae. (amphiarthrotic).
The most common example of immovable joints are found in the sutures of the adult skull. The teeth in their sockets form immovable joints as well. The growth plates of children's long bones are immovable joints. The joint between the first rib and the breastbone is also an immovable joint.
second rib
Ribs 1 through 7. The cartilage of rib 1 attaches to the manubrium. The cartilage of rib 2 attaches to the manubrium and the body. The cartilage of ribs 3 through 7 attach to the body and sometimes to a small portion of the xiphoid process.
According to Ross and Wilson Anatomy and Physiology, 2 pairs
The Costochondral Joint is an immovable Cartilaginous - Synchodrosis (structural classification) joint that articulates the ribs with the coastal cartilage.It's functional classification is; Synarthrosis - a type of joint permitting no movement at all.
Costochondral joint ( Costo- = Rib, Chondro- = Cartilage) - these joints 'articulate' the ribs with the costal cartilage of the thoracic wall. However, there is no movement between the two.The Structural Classification for this joint is; Cartilaginous (Synchodrosis).The Functional Classification for this joint is; Synarthrosis.
