The spleen is located behind the ribs, specifically in the upper left quadrant of the abdomen. It is nestled against the diaphragm and lies just beneath the 9th to 11th ribs. While it is protected by the rib cage, it is not directly below the ribs; rather, it is positioned more towards the back of the abdominal cavity.
True ribs (ribs 1-7) articulate with the vertebral column at the thoracic vertebrae and also attach directly to the sternum at the front of the chest through costal cartilage. This connection provides structural support and protection for the internal organs located in the chest cavity.
The ribs located between the 5th and 8th ribs in the human body are the 6th and 7th ribs.
The 11th and 12th pairs of ribs are called floating ribs because they are not attached to the sternum or connected to other ribs through cartilage. Instead, they only attach to the vertebrae in the back, leaving them free at the front. This lack of anterior attachment gives them a "floating" appearance, allowing for greater flexibility and movement in the lower ribcage.
