The term 'connector bone' refers to the LIGAMENT and SINEW that connect bones together. LIGAMENT is an 8-letter word that is a band of tough, fibrous tissue that connects bones or cartilage at a joint and provides support and strength. SINEW is a 5-letter word that is a tough, fibrous tissue that connects muscles to bones and is responsible for transmitting the force generated by muscle contraction. Together, these two tissues form the connector bone, which is essential for providing stability and movement to the body.
