Normal levels are less than 500 mIU/L [20 ng/mL or Âµg/L] for women, and less than 450 mIU/L for men. Prolactin is a peptide hormone produced by the anterior pituitary gland that is primarily associated with lactation and plays a vital role in breast development during pregnancy.
Â© A Dictionary of Biology 2004, originally published by Oxford University Press 2004. cymose inflorescence (cyme; definite inflorescence) A type of flowering shoot (see inflorescence) in which the first-formed flower develops from the growing region at the top of the flower stalk (see illustration).n a dichasial cyme (or dichasium), the development of the flower at the apex is followed by two new flower axes developing from buds opposite one another, as in plants of the family Caryophyllaceae (such as stitchwort).
racemose inflorescence (indefinite inflorescence) A type of flowering shoot (see inflorescence) in which the growing region at the tip of the flower stalk continues to produce new flower buds during growth.As a result, the youngest flowers are at the top and the oldest flowers are at the base of the stalk.n a flattened inflorescence, the youngest flowers are in the centre and the oldest flowers are on the outside. Types of racemose inflorescence include the capitulum, catkin, corymb, raceme, spadix, spike, and umbel (see illustration).
