Document Summary
Molecules of ache are embedded in the end plate. This enzymes breaks down ach and when it is released from the motor neuron some molecules are immediately inactivated, other molecules will be inactivated after bidding the achr, eventually all will be broken down. This is one of the major ways a nt gets broken down in the nervous system generally. As soon as ach is released, some of it will make it to the receptor and some will be broken down. They have a repetitive hierarchical structure: tubes inside tubes inside tubes . Within the muscle are a bunch of muscle bers (which are muscle cells). They are much longer than a normal cell. A muscle cell has bundles of proteins inside which form long tubes. These protein complexes ll up the muscle bers. Bers has many of these, which are called myo brils. In you skeletal muscles (voluntary), there is a pattern of striation between dark and light.
