Study Notes
Characteristics of Upper Motor Neuron (UMN) and Lower Motor Neuron (LMN) Lesions
- A lower motor neuron lesion is characterized by flaccid paralysis, muscle atrophy, and decreased or absent deep tendon reflexes.
- An upper motor neuron lesion is characterized by spastic paralysis, increased deep tendon reflexes, and a positive Babinski sign.
Functions of Upper Motor Neurons and Corticospinal Tract
- The upper motor neuron is responsible for controlling voluntary movements.
- The corticospinal tract is responsible for transmitting motor signals from the cerebral cortex to the spinal cord.
Spinal Muscular Atrophy (SMA) and Amyotrophic Lateral Sclerosis (ALS)
- Spinal Muscular Atrophy (SMA) is a genetic disorder that affects the lower motor neurons, resulting in muscle atrophy and weakness.
- Amyotrophic Lateral Sclerosis (ALS) is a degenerative motor neuron disease that affects both upper motor neurons and lower motor neurons, leading to muscle weakness, atrophy, and paralysis.
Neuropathy
- Mononeuropathy is a condition where only one peripheral nerve is affected.
- Polyneuropathy is a condition where multiple peripheral nerves are affected simultaneously or sequentially.
- Axonal neuropathy affects the axon of the nerve, while demyelinating neuropathy affects the myelin sheath.
- The most common cause of polyneuropathy is diabetes.
Carpal Tunnel Syndrome
- Carpal tunnel syndrome is a type of mononeuropathy that affects the median nerve in the wrist.
- Treatment options for carpal tunnel syndrome include medication, physical therapy, and surgery.
Motor Neuron Diseases
- Amyotrophic Lateral Sclerosis (ALS) is a degenerative motor neuron disease that affects both upper motor neurons and lower motor neurons.
- The term used to describe a degenerative motor neuron disease that affects both upper motor neurons and lower motor neurons is motor neuron disease.
