Which is not a function of tendons?

The primary function of tendons is to connect muscles to bones, facilitating the transmission of forces generated by muscular contractions to enable movement at joints. Tendons are composed of dense regular connective tissue, which allows them to effectively transmit tensile forces, aiding in locomotion and stability of the skeletal system.

While tendons indeed allow for body movement, their role does not involve connecting bones to other bones; that function is specific to ligaments. Ligaments serve to stabilize joints by connecting bones to each other, while tendons are strictly involved in the connection between muscles and bones.

The other functions, such as transmitting tensile forces and contributing to body locomotion, are inherent to the structure of tendons. Therefore, the correct choice reflects a misconception regarding the roles of tendons versus ligaments in the musculoskeletal system.
