Muscles

 

According to Dr Brownstone, the brain views muslces as against gravity - extensors.

extensor muscles are antigravity muscles - gastrocnemius

 

rest are flexors

 

Skeletal Muscle

red muscle - lots of microtubules, weak, slow, sustained - S motorneurons

intermediate muscle - intermediated - FR motoneurons

white - few microtubules, strong, fast, fatiguable - FF motoneurons
