Skeletal muscles move via action potential that is conducted by axons to the neuromuscular junction and across the synaptic gaps of efferent motor neurons. The main neurotransmitter responsible for this job is acetylcholine.

What bones are involved in pull ups?

Pull ups primarily target the muscles in the back and arms, including the latissimus dorsi, biceps, and forearms. While the bones that make up the arms (humerus, radius, ulna) are involved in the movement, the main bones directly involved in pull ups are the scapulae (shoulder blades) and the spine. The scapulae move and stabilize during pull ups, while the spine provides support and alignment throughout the exercise.


Why do your arms swing when walking?

TO KEEP BALANCE The basal ganglia (sub-cortical structures of the brain involved in movement control) are quite old in evolutionary terms, therefore they are still tuned to tetrapod/quadruped movement. When we initiate voluntary movement the basal ganglia "assume" that our arms (which used to be the first pair of legs, in a sense) should be moving as well. More recent research suggests that it actually counters the turning torque as each leg pivots off centre.. For much much more info see the paper by Yu Li and partners at Liverpool university on movements related to Human Arm Swinging published 5th December 2000 in the journal of experimental Biology.. For a less taxing explanation there is a decent report from Cosmos at http://www.cosmosmagazine.com/news/2888/why-we-swing-our-arms-when-we-walk cheers Mar

Do dogs have arms or legs, and how do they use them differently from humans?

Dogs have legs, not arms. They use their legs for walking, running, jumping, and digging. Unlike humans, dogs primarily use their front legs for support and balance, while their hind legs provide power for movement.


Are your bones in the arms and legs long or short?

Bones in the arms and legs tend to be long bones, which are characterized by their elongated shape and serve to support the body and facilitate movement. Short bones, like those found in the wrists and ankles, have a different structure and function.
