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.
Technically, two growth plates may be considered to exist in immature long bones: the horizontal growth plate (physis) and the spherical growth plate (enables epiphyseal growth). For the purposes of this article, the horizontal growth plate is addressed.
