| What are the general functions of the Muscular system | 1. Movement 2. Heat production 3. Posture |
| What is the neuromuscular junction NMJ? | A synaptic connection between the terminal end of a motor nerve and a muscle |
| True or False: During contraction, myosin cross bridges pull the thin filaments away from the center of each of two sarcomeres, thus shortening the myofibril and the entire muscle fiber. | False: During contraction, myosin cross bridges pull the thin filaments TOWARD the center of each of two sarcomeres, thus shortening the myofibril and the entire muscle fiber. |
| The three phases of the twitch contraction are: | the latent period, the contraction phase, and the relaxation phase |
| Smooth, sustained contractions are called tetanic contractions or called: | Tetnus |
| Tonic contraction, or muscle tone, is the low level of continuous contraction characteristic of the muscles of normal individuals when they are awake. This is important because | Muscle tone plays an important role in posture. |
| What body parts is cardiac muscle found in? | only the heart |
| Which two types of muscles are involuntary? | Cardiac and Smooth |
| Which muscle cells contains zero gap-junctions? | Skeletal |
| True or false: Skeletal muscles contain many nucleuses | True |
