FUSIMOTOR NEURONS Meaning and
Definition
-
Fusimotor neurons, also known as gamma motor neurons, are a specific type of motor neuron that play a crucial role in the control and regulation of muscle activity. They are essential components of the motor system, responsible for modulating the sensitivity and responsiveness of muscle spindles, which are sensory receptors located within skeletal muscles.
These neurons differ from alpha motor neurons, which directly innervate the main muscle fibers and are responsible for generating muscle contractions. Instead, fusimotor neurons innervate the muscle spindle's intrafusal fibers, which run parallel to the main muscle fibers. Through this innervation, they are able to regulate the muscle spindle's sensitivity and stretch reflexes.
Fusimotor neurons can be divided into two subtypes: dynamic and static. Dynamic fusimotor neurons respond primarily to the velocity or speed of muscle length changes, while static fusimotor neurons are primarily involved in maintaining muscle tone or tension.
Overall, the activity of fusimotor neurons helps to regulate the sensitivity and responsiveness of muscle spindles, ensuring accurate and precise control of muscle movements. Dysfunction or damage to these neurons can result in abnormal muscle control, reflex abnormalities, or motor impairments. Understanding the function and properties of fusimotor neurons is vital for advancing our knowledge of motor control and improving treatment strategies for various motor-related disorders.

Etymology of FUSIMOTOR NEURONS
The term "fusimotor neurons" comes from the combination of the words "fusi-" and "motor" along with the suffix "-neurons".
1. Fusi-: The prefix "fusi-" is derived from the Latin word "fusus", which means "spindle-shaped". It refers to the spindle-like structure of certain muscle fibers.
2. Motor: The word "motor" comes from the Latin word "mōtor", which means "mover" or "driver". It is related to the verb "mōtus", meaning "to move". In the context of neural physiology, "motor" refers to the neurons that control movement and muscle activity.
3. Neurons: The term "neurons" originates from the Greek word "neuron", which means "sinew" or "nerve".
