In some neurodegenerative diseases, some lower motor neuron cells die and the remaining lower motor neurons continuing the process of the vacated dead motor neuron cells to innervate the neuron and muscle synapses.
The size of the motor unit increases and due to the innervations of the new axon
increases the strength of the muscle contraction occurred by individually activating each surviving motor neuron. Here multiple motor units will be controlled by a single neuron.

Scientists study both the flatworm Planaria and the roundworm Caenorhabditis elegans in laboratories, using them as test subjects, and while they may seem similar, they have some distinct internal and external differences. Flatworms (phylum Platyhelminthes) and roundworms (phylum Nematoda) differ in shape, means of locomotion, how their digestive systems function, and in the ways they are harmful to human beings. While both species are called worms, they are not closely related.
