Final answer:
Fibrous joints, also known as synarthroses, are joints where adjacent bones are strongly united by fibrous connective tissue. They include sutures, syndesmoses, and gomphoses, which are found in the skull, between parallel bones, and between teeth and their sockets in the jaw, respectively.
Step-by-step explanation:
Fibrous joints, also known as synarthroses, are joints where adjacent bones are strongly united by fibrous connective tissue. The three types of fibrous joints are sutures, syndesmoses, and gomphoses. Sutures are found in the skull, syndesmoses are found between parallel bones like the forearm and leg, and gomphoses are found between the roots of teeth and their sockets in the jaw. Fibrous joints provide protection and stability to the body.
