Neuro #28 reflexes and spindles.txt

Small b/c their threshhold is lower

Golgi tendon organs (which is why it is the last player in reflexes)

• Golgi tendon organ
• Signal from 1b fibers that synapse on interferons
• Inhibition of Alpha motor activation

• When a painful sensory stimulus is acquired
• Sensory nerve signals interneurons to synapse on alpha motor neurons
• Both excitatory and inhibitory synapses occur

• Same painful stimulus crosses SC and synapses on interneurons
• Interneurons synapse on excitatory and inhibitory alpha motor neurons
• Excitatory: extensors excited
• Inhibitory: flexors inhibited

**Goal is to maintain balance with one leg while the other is moving away from painful stimulus
