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.
Muscle
A nematode is a multicellular organism composed of millions of cells. Each cell contains numerous atoms, including carbon, hydrogen, oxygen, nitrogen, and others. Therefore, there are a very large number of atoms in a nematode.
Smooth muscle tissue has longitudinally and circularly arranged layers.
They are cold blooded organisms.
Schistosoma is not a nematode, is a genus of Trematode under Phylum Platyhelminthes meaning the flatworms, nematode are round unsegmented worms.

The Esophagus has 9 specific layers, if you are healthy. They are: mucosa, saliva, lamina propria, smooth muscle, papillae, muscularis extenma, striated muscle, and adventa.
The muscle layers of the small and large intestines are composed of smooth muscle tissue, which is specialized for involuntary contractions. This smooth muscle is organized into two layers: an inner circular layer and an outer longitudinal layer, facilitating peristalsis and segmentation movements that aid in digestion and absorption.
The human body has three main layers of muscle: the skeletal muscle, which is attached to bones and allows for voluntary movement; the smooth muscle, which is found in the walls of internal organs and is involuntary; and the cardiac muscle, which makes up the heart and is also involuntary. Each type of muscle serves a distinct function within the body.
