Answer:
A, B and C are all correct.
Step-by-step explanation:
There are three main muscle types:
- Muscle skeleton — the specialized tissue that connects to the bones and enables movement. The musculoskeletal system is called skeleton muscles and bones together (also known as the locomotor system). Generally speaking, the biceps and triceps of the front or the back of the upper arm are arranged into opposing pairs. Skeletal muscles are controlled by humans, and so are also called voluntary muscles. Another term is streaked muscles, as the tissue looks streaked on a microscope.
- smooth muscle -located throughout several internal tissues such as the digestive tract, the uterus, and blood vessels such as the artery. The smooth muscle in layered sheets is placed along the construction length in waves. Another typical word is an involuntary muscle, because, without our knowledge, the motion of the smooth muscle takes place.
- The cardiac muscle - the heart muscle. Without our conscious awareness the heart contracts and relaxes.
