Module motor 

Motor neuron models for spinal and cortical motor circuits.

Motor model group: alpha motor, gamma motor, upper motor, Renshaw cell, motor unit. Added one by one with full 7-point checklist verification.

Structs

AlphaMotorNeuron

Alpha motor neuron — spinal cord, innervates extrafusal muscle fibres.

GammaMotorNeuron

Gamma motor neuron — innervates intrafusal fibres of muscle spindles.

MotorUnit

Motor unit — functional unit of motor control: alpha motor neuron + muscle fibre.

RenshawCell

Renshaw cell — spinal inhibitory interneuron for recurrent inhibition.

UpperMotorNeuron

Upper motor neuron — layer 5 pyramidal cell, corticospinal projection.
