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.
The long bones of the body do not grow from the center outward. Instead, growth occurs at each end of the bone around the growth plate. The growth plate is the last portion of the bone to harden (ossify), which leaves it vulnerable to fracture.Because muscles and bones develop at different speeds, a child's bones may be weaker than the surrounding connective tissues (ligaments).Children's bones heal faster than adult's bones.he growth plate is the last portion of the bone to harden (ossify), which leaves it vulnerable to fracture.
