Question: What is a concubine? Why did God allow men to have concubines in the Bible? Answer: A concubine is a female who voluntarily enslaves and sells herself to a man primarily for his sexual pleasure. Concubines in the patriarchal age and beyond did not have equal status with a wife.
The type of muscle that is voluntary and striated is skeletal muscle. This type of muscle has a banded appearance called striations. The peripheral nervous system controls skeletal muscle.
Striated, or skeletal, muscle forms the bulk of the body's muscle tissue and gives the body its general shape. It is called striated because it appears striped, in alternating bands of light and dark, when viewed under a microscope, and animals have conscious control over most of their striate muscles.
