| Question | Answer |
|---|---|
| 4 major tissues of the body | 1. Muscle 2. Epithelial 3. Connective 4. Nervous |
| How many different types of muscle tissue, and they are? | 3. skeletal,cardiac,and smooth muscle |
| Cells in muscle tissue are (2 things) | cylindrical and multinucleated |
| Skeletal muscle tissue is voluntary or involuntary? | Voluntary |
| Why is skeletal muscle loose? | So it can be able to contract |

| Muscle fiber | muscle cell |
| Endomysium | around each muscle fiber |
| Sarcolemma | plasma membrane of a muscle fiber |
| Sarcoplasm | cytoplasm of a muscle fiber |
| Nuclei | located peripherally in skeletal muscle fibers, just beneath the sarcolemma |
| myofibril | organelle found in skeletal muscle cells |
| sarcomemre | one myofibril can be composed of 10,000 sarcomeres |
| sarcoplasmic reticulum | wraps around each myofibril |
| terminal cisternae | one t-tubule lies between two terminal cisternae |
| t-tubule | encircle the myofibrils |
| Triad | bne t-tubule between two terminal cisternae |
| Filament theory | actin slides over myosin |
| A neuromuscular junction looks like? | Big League Chew or neat strips of pink ribbon |
