Hypothalamic–pituitary–thyroid axis and TSH receptor antibodies may be the reason for the observation that the relation between free T4 concentration and TSH levels deviates from a pure loglinear relation that has previously been proposed. Standard procedures cover the determination of serum levels of the following hormones: For special conditions the following assays and procedures may be required: Hypothalamic–pituitary–thyroid axis The hypothalamic–pituitary–thyroid axis (HPT axis for short, a.k.a. thyroid homeostasis or thyrotropic feedback control) is part of the neuroendocrine system responsible for the regulation of metabolism. As its name suggests, it depends upon the hypothalamus, the pituitary gland, and the thyroid gland. The
Tank controls 3D games. Most first-person shooter games still use a version of tank controls with the WASD keys, but the use of a mouse or analog stick makes turning easy. Tank controls Tank controls refers to a control system used in video games. In a game with tank controls, players control movement relative to the position of the player character. Pressing up (for example on a D-pad, analog stick, or cursor movement keys) on the game controller moves the character in the direction they face, down reverses them, and left and right rotates them. This differs from many 3D games, in
