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 because the muscle has reached tetanic contraction) ii. Effects of Ach blocker- tubocurare- twitch tension declines. Blocks Ach and no muscle contraction. It is necessary for acetylcholine to bind to receptors in order for sodium

A motor unit consists of a ___1___ and all the ___2___ it innervates. Whole muscle contraction is a(n) ___3___ response. A ___4___ is the response of a muscle to a single‚ brief threshold stimulus. When the frequency of stimulation is so high that the muscle tracing shows fused peaks‚ ___5___ has been achieved. ___6___ is the stimulus strength at which the first observable muscle contraction occurs The phenomenon‚ called ___7___‚ brings more and more muscle fibers into play

6) The ends of the Purkinje fibers allow the ventricular muscles cells to contract because the action potential is rapidly passes through the AV bundle to the end of the Purkinje and this cause a rapid conduction and its providing a very strong contraction to the ventricular muscle. The intercalated discs are a network that allows the rapid transmission of the electrical impulses and this allows the action potentials to travel to one cardiac muscle cells to the next.

structures and joints function as pivot points. Skeletal‚ or striated‚ muscles are connected to the bones either directly or by tendons‚ strong bundles of collagen fibers. Two or more muscles usually work antagonistically. In this arrangement‚ a contraction of one muscle stretches‚ or elongates‚ the other. Skeletal muscle is composed of long‚ multinucleate cells called fibers. These fibers are innervated by motor nerves. An action potential in a motor axon produces an action potential in the muscle
