Episode notes
Action Potential Generation
- Depolarization occurs when sodium channels open and sodium rushes into the neuron, causing an action potential.
- The threshold to trigger this is around -55 millivolts.
Proprioception and Movement Control
- Proprioception tells the brain about body position and movement without visual input.
- It allows smooth coordinated movement by providing feedback from muscles, joints, and tendons.
Golgi Tendon Organs Protect Muscles
- Golgi tendon organs detect muscle tension and inhibit muscle contraction when tension becomes damaging.
- They protect muscles and tendons from injury by sending inhibitory signals to the CNS.
