Antidiuretic hormone (ADH, vasopressin) is produced by the supraoptic and paraventricular nuclei of the hypothalamus and travels in the axons through the pituitary stalk to the posterior pituitary gland.
What is a foreign key in SQL Server? A foreign key is a way to enforce referential integrity within your SQL Server database. A foreign key means that values in one table must also appear in another table. The referenced table is called the parent table while the table with the foreign key is called the child table.
A foreign key in a table is actually the primary key of the table on the other side of the join. It serves as the âpointerâ that links two specific records (one in each of the related tables) to each other. In a 1:M relationship, the foreign key generally is created in the table on the many side of the join.
