Lower Motor Neurons (Spinal) is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Spinal lower motor neurons (LMNs) are the final common pathway for motor control, directly innervating skeletal muscle. They receive input from upper motor neurons, interneurons, and sensory neurons. [@neuroscience2001]

Overview
Mermaid diagram (expand to render)
Lower Motor Neurons (Spinal), also known as anterior horn cells, are motor neurons located in the anterior (ventral) horn of the spinal cord. These neurons receive input from upper motor neurons via the corticospinal tract and directly innervate skeletal muscles. Lower Motor Neurons are the final common pathway for voluntary movement, transmitting signals from the brain to muscles. Degeneration of lower motor neurons causes muscle weakness, atrophy, fasciculations, and hyporeflexia. Spinal Lower Motor Neuron degeneration is a hallmark of spinal muscular atrophy (SMA) and is also affected in amyotrophic lateral sclerosis (ALS). [@fundamental2012]
