Lower Motor Neurons
Based on the given context, lower motor neurons are a type of motor neuron whose cell bodies reside in the brainstem or spinal cord. They transmit signals from the Central Nervous System (CNS) to the muscles. When there is a lesion or damage to the lower motor neurons, several effects can occur. These include the loss of excitation of the muscle, leading to paralysis and flaccidity (decreasoed muscle tone). Reflexes also disappear, and the affected muscle may eventually atrophy. Lower motor neurons are considered a bottleneck in the motor pathway.
