The muscle fibers of an earthworm run vertically along the entirety of the worm.

Although the worm has not bones, it does have a hydro scleten which is basicly water and it allows the worm to move by contracting muscle's.
they have 2 layers of muscle
Nematodes, also known as roundworms, have a unique body structure characterized by four muscle layers. These layers are arranged longitudinally, allowing for a distinctive thrashing motion. The muscle fibers are organized into two main groups: the dorsal and ventral muscles, which enable the worm to move efficiently in its environment. This arrangement is key to their locomotion and overall function.
In an adult worm, there may be more than 100 segments.
The core of the apple but be careful you may eat a worm!
contractions like muscle
i think its the earthworm
There isn't technically a silk plant. Silk worms make silk. They spin a cocoon and silk comes from the fibers in the cocoon. Linen is made from the fibers of the flax plant.
Bevel gears can change the speed and motion and Worm gears can reduce speed and direction of motion.
In worm gears, an axle or shafts has a screw that connects with another gear. This system is used when you need to change the direction of motion and reduce speed
Earthworm have narrow bands of circular muscle fibers around their bodies and longitudinal muscles that control the length of their bodies located inside the circular muscles. These two sets of muscles, which are attached to the bristle-like setae on the outside of the body, work together to change the length and thickness of the worm so it can move.
