If motor neurons are damaged, a person may experience muscle weakness, paralysis, or atrophy, as these neurons are responsible for transmitting signals from the brain to the muscles. This can lead to difficulty in movement, coordination, and performing daily activities. Additionally, damage to motor neurons can result in conditions such as amyotrophic lateral sclerosis (ALS) or spinal muscular atrophy, which progressively worsen over time. Overall, such damage significantly impacts a person's mobility and quality of life.

What happens when a motor neuron in a reflex arc is damaged?
When a motor neuron in a reflex arc is damaged, the transmission of signals from the spinal cord to the muscles is interrupted. This can result in a loss of motor function or muscle weakness in the affected area, as the muscles can no longer receive the necessary signals to contract. Consequently, reflex actions involving that motor neuron may be diminished or absent, leading to impaired reflex responses. Overall, damage to a motor neuron disrupts the normal functioning of the reflex arc.
What is descending tract and one ascending tract in upper motor neuron and lower motor neuron?
central nervous system (CNS) is the descending tract and one ascending tract in upper motor neuron and lower motor neuron.
What lies between the sensory neuron and the motor neuron?
Between the sensory neuron and the motor neuron lies the interneuron. Interneurons communicate and process information within the central nervous system, helping to integrate and coordinate sensory inputs with appropriate motor outputs.
What does axon terminal of motor neuron release?
The axon terminal of a motor neuron releases the neurotransmitter acetylcholine. Acetylcholine is responsible for transmitting signals from the motor neuron to muscle fibers, leading to muscle contractions.
What connects sensory to motor neuron?
Interneurons(also called relay neuron, association neuron, connector neuron or local circuit neuron) are multipolar neurons that connects sensory neurons to motor neurons.

Is motor a neuron?
motor neuron is a type of neuron that found at the muscles, tissues, and organs.
How are motor and sensory neurons categorized?
Motor Neuron and Sensory Neuron
What is a motor neuron attached to?
A Motor neuron is a neuron that carries impulses from the spinal cord to muscle cells.A Motor neuron is a neuron that carries impulses from the spinal cord to muscle cells.
What are the special concerns surrounding patients with motor neuron diseases?
It is important to remember that even in the most severe motor neuron diseases, a person's personality, intelligence, reasoning ability, or memory are not impaired
What are similarities between sensory and motor neuron?
Motor neuron has got a motor.. but you have to peddle sensory neurons.
What is descending tract and one ascending tract in upper motor neuron and lower motor neuron?
central nervous system (CNS) is the descending tract and one ascending tract in upper motor neuron and lower motor neuron.
What is the 3 types of neuron?
one type of neuron is the motor neuron
What is a motor neuron?
motor neuron is a type of neuron that found at the muscles, tissues, and organs.
Is motor neuron disease the same as ALS?
no yes, it is Lower Motor Neuron Disease
Where is the motor neuron located?
The motor neuron cells are all in the brain and the spinal cord.
What is the difference between a motor unit and a motor neuron in the context of muscle movement?
A motor unit consists of a motor neuron and the muscle fibers it controls. The motor neuron sends signals to the muscle fibers to contract, while the motor unit refers to the combination of the neuron and the muscle fibers it innervates.
