The function of the retractor muscle in bulls is to form a sigmoid flexure (s-shaped curve) in the penis in order to hold it inside the sheath when not erect.

The mantle retractor muscle is a muscle found in mollusks that is responsible for retracting the mantle. The mantle is a fold of skin that surrounds the internal organs of mollusks and plays a role in shell formation, respiration, and protection. The contraction of the mantle retractor muscle allows the mollusk to withdraw its soft body into the protective shell.
Bulls have what is called the Sigmoid Flexure which is a muscle that expands to allow erection for copulation, and then contracts, pulling the penis back into the bull's body during the time when the penis is not needed.
Circular muscles help in extension and narrowing of the body of the earthworm. When circular muscles contract the protractor muscles relax causing the retractor muscles to contract, thus withdrawing the setae.
The proximal bulb is the widened part at the start of the bull's penis. It is surrounded by a muscle called the retractor penis muscle, which helps with the erection and movement of the penis during mating.
Jan Mikulicz-Radecki invented the deaver retractor. The deaver retractor is a medical device that was invented in the year of 1904.
A volkman retractor is a type of tissue retractor used during ceritan surgeries to separate incised tissues. Google images it for pictures.
The muscle tissue's main function is to contract.
it is a self retaining retractor, which is used to retract wound edges.
A Michotte retractor is a surgical instrument used primarily in orthopedic and neurosurgery procedures. It is designed to hold back soft tissue or muscle, providing better visibility and access to the surgical site. The retractor features a curved, flat design and is typically made of stainless steel, allowing for both strength and flexibility during surgery. Its design minimizes trauma to the surrounding tissues while maintaining a clear field for the surgeon.
