Canine TSH may be measured at 30 minutes as part of a TRH stimulation test in the diagnosis of secondary hypothyroidism. Normal dogs should increase cTSH by at least 0.4 ng/mL. Total T3 (TT3) â The analysis of TT3 is of little value in the diagnosis of hypothyroidism principally because of the high prevalence of cross-reacting T3 autoantibodies (T3AA) in hypothyroid dogs.
The forward (leading) edge of the sail is called the luff, which, in a mainsail, is parallel to the mast. The aft (back) edge of a sail is called the leech (also spelled leach), which is opposite the luff, and forms the hypotenuse of the triangle.
The basic approach is to come up with a basic body compartment, like cars on a train, and build up a body by adding more. It is a quick and simple way to add size, and segmented worms, also known as annelids, are the prototypes. The leeches are less segmented than the other types, although the basic body plan of the adult almost always starts with 34 segments between front and back (this is common in other segmented groups, where a set number of segments arises in embryos as the base architecture).
