What does a high TSH mean? TSH or thyroid stimulating hormone is a hormone produced in the anterior pituitary gland. This is used to help stimulate the thyroid to produce triiodothyronine (T3) or thyroxine (T4), hormones that help stimulate the metabolism.
An epiphyseal plate, more commonly known as a growth plate, is a anatomical structure present at the ends of the long bones of children and adolescents. These plates contain rapidly dividing cells that allow bones to become longer until the end of puberty.
These new cells become part of the body's long bones. Growth plates play a large role during puberty, most noticeably when an adolescent goes through a growth spurt. By age 18 in females and 21 in males, a growth plate will have become an epiphyseal line.
