|
| 14. | These antigravity muscles are extensor muscles in the legs that help maintain upright and balanced posture.
|
| 15. | It provides motor function through innervation to most extensor muscles of the posterior arm and forearm.

|
| 17. | Unlike most arthropods, spiders have no extensor muscles in their limbs and instead extend them by hydraulic pressure.
|
| 18. | The focus on gripping muscles versus wrist extensor muscles can be varied based upon the thickness of the bar.
|
| 19. | At that location, the interneuron excites the alpha motor neurons that innervate the extensor muscles of the opposite leg.
|
| 20. | This decreases the rate of muscle shortening and increases the force generated by extensor muscles during the push off phase.
