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).
Written By: Inflorescence, in a flowering plant, a cluster of flowers on a branch or a system of branches. An inflorescence is categorized on the basis of the arrangement of flowers on a main axis (peduncle) and by the timing of its flowering (determinate and indeterminate). Determinate inflorescence. 1  In determinate (cymose) inflorescences, the youngest flowers are at the bottom of an elongated axis or on the outside of a truncated axis. At the time of flowering, the apical meristem (the terminal point of cell division) produces a flower bud, thus arresting the growth of the peduncle.
