Describe (not just define!) the functional unit called a motor unit. Explain the relationship between motor unit size in finely vs. coarsely controlled muscles. Explain how motor units act to establish muscle tone. What are the functions of muscle tone? Motor Unit- One motor neuron and all the muscles it innervates. Each muscle will respond to one motor nerve which contains axons that can have up to 100’s of neurons that branch into terminals that form NMJ with ONE fiber. When a motor neuron sends

The Grand Canyon was once a part of a continental collision about 1.7 billion years ago when volcanic islands collided in the south west of America‚ where the North American plate is now. Mountain building occurred about 75 million years ago when the uplift of almost 2 miles in the region‚ (called a Laramide orogeny event) started and created the Colorado Plateau. The rocks in the Grand Canyon were igneous or sedimentary rocks before the collision of tectonic plates. The collision pushed the plates

Frog‚ sciatic nerve‚ gastroc‚ d. What was investigated? i. Effects of stimulus frequency and intensity on contraction-the more intensity‚ the higher the twitch tension. The more freq- the more twitch tension (By ~4.0pps we start to see summation of the twitches and by ~15pps we see no single twitches

FROG MUSCLE PHYSIOLOGY 2) What was the smallest voltage required to produce max contraction? What proportion of the muscle fibers in the muscle do you think were contracting to produce this maximal response? Muscle fibers act in response to isolated stimuli in an all or none fashion. However‚ a muscle organ‚ such as the gastrocnemius muscle‚ is composed of many individual muscle fibers. It is known that all of the fibers in a muscle do not have the same threshold and that a stimulus applied to

placed rocks and fossils into eras and periods. With a relative time scale‚ scientists were able to work together to establish a timeline they could use to categorize the age in which the rock or fossils existed.

What Is Grand Strategy?* by John Lewis Gaddis** Yale University When my colleagues Paul Kennedy‚ Charlie Hill‚ and I first began talking about setting up a grand strategy course at Yale in the late 1990s‚ at least half the people to whom we tried to explain this thought we were talking about “grant” strategy: how do you get the next federal or foundation grant? This misunderstanding would not have occurred‚ I think‚ during the fifty years of insecurity that separated the Japanese attack on Pearl

Would you rather have a national park or nothing at all. Have you ever been to a Providence Canyon? If so‚ did you feel like you where in a Grand Canyon. Well many people call Providence Canyon the little Grand Canyon. I am against the federal government decision. We should have a national park. Maybe if we had a national park more people would go out and see it. I am for the federal government decision‚ because the farmers came down cutting the trees and‚ started planting their seeds in long straight
