What are the examples of tulang pandulaan?

Tulang pandulaan, also known as pendulum bones, are bones that are suspended in a way that allows them to swing or move freely. These bones are found in some animals, but not in humans.

Here are some examples of animals with pendulum bones:

* Birds: The sternum, or breastbone, of birds is a classic example of a pendulum bone. It's attached to the ribs and serves as the anchor for the flight muscles. The sternum can move back and forth during flight, allowing for powerful wing movements.

* Some fish: Certain fish species, like the swordfish, have a rostrum (elongated snout) that acts as a pendulum bone. This rostrum allows the fish to more effectively maneuver through water and hunt prey.

* Other animals: Some reptiles, such as chameleons, also have pendulum bones in their skull that allow for independent movement of their eyes.

It's important to note that not all animals have pendulum bones. These are specialized adaptations that evolved in certain species to meet specific needs related to movement, locomotion, or feeding.
