The neuron is initially in a resting potential state where it is negative on the inside of the cell and positive on the outside. This is created by a sodium potassium pump that actively transports Na+ and K+ across the cell membrane.
Depolarization is the action potential traveling along the neuron. Depolarization begins when the stimuli opens sodium channels causing a temporary change in the cells polarization.(Relative to one another- positive on the inside, negative on the outside)
Repolarization begins immediately following depolarization where the resting potential is restored. This is known as the refractory period.
A golgi tendon is located at the insertion of skeletal into the muscle fibers of skeletal muscles.
They serve as “safety devices” that help prevent excessive force during muscle contraction.
Golgi tendon organs send how far the individual wants to jump to the spinal cord through sensory neurons which travels to the brain.
The brain interprets the sensory message and formulates a response, sends the message back through motor neurons which tells the gogli tendon organs how much to monitor the muscle contraction before the individual jumps.
