1. Skeletal muscles have the property of regeneration and form the new tissues.
2. The three types of muscle tissues are cardiac, smooth, and skeletal. Skeletal muscle is a form of striated muscle tissue which is under the voluntary control of the somatic nervous system.
3. Myoglobin is an iron and oxygen-binding protein found in the muscle tissue of vertebrates and in all mammals. It is related to hemoglobin which is iron and oxygen-binding protein in the blood, specifically in the RBCs.
4. The sarcoplasmic reticulum is a specialized type of smooth ER that regulates the calcium ion concentration in the cytoplasm of striated muscle cells.
6. In the isotonic contraction, the muscle produces slightly more tension than the load we want to lift. It's also important to note there are 2 types of isotonic contractions. Concentric contractions occurs when the muscle shortens.
7. All muscle cells have a little ATP within them that they can use immediately but only enough to last for 3 seconds so all muscle cells contain a high energy compound called creatine phosphate which is broken down to make more ATP quickly.
