The muscle fibers in frogs are arranged in a specific pattern to facilitate movement. They are oriented in layers and run in different directions to provide strength and flexibility. This arrangement allows frogs to have efficient and powerful muscle contractions for activities like jumping and swimming.
The ventral roots contain motor fibers.
motor
The ventral roots contains motor fibers, responsible for motion, whereas the dorsal sensory fibers, responsible for touch and feeling.
The ventral ramus of a spinal nerve contains both sensory and motor nerve fibers. These fibers innervate the muscles, joints, and skin on the front part of the body.
The ventral root of a spinal nerve contains only efferent fibers, which carry motor signals from the central nervous system to the muscles and glands in the body.
No, the ventral ramus contains both motor and sensory fibers. It is a branch of the spinal nerve that provides innervation to various muscles, skin, and structures in the body.
molecules are arranged in good order along the fibers
Planarian ventral nerve cords are bundles of nerve fibers located on the ventral (underside) surface of the planarian flatworm. These nerve cords coordinate the worm's movement, feeding, and response to stimuli. They are part of the planarian's simple nervous system that allows it to navigate its environment.

Muscle fibers can be arranged into two basic structural patterns, fusiform and pinnate. Most human muscles are fusiform, with the fibers largely arranged parallel along the muscle's longitudinal axis. In many of the larger muscles the fibers are inserted obliquely into the tendon, and this arrangement resembles a feather. The fibers in a pinnate (feather) muscle are shorter than those of a fusiform muscle. The arrangement of pinnate muscle fibers can be single or double, as in muscles of the forearm, or multipinnate, as in the gluteus maximus or deltoid.
