The cardiovascular centre affects changes to the heart rate by sending a nerve impulse to the cardiac pacemaker via two sets of nerves: sympathetic fibres, part of the autonomic nervous system, to make heart rate faster. the vagus nerve, part of the parasympathetic branch of the autonomic nervous system, to lower heart rate.
The adrenal glands may not develop at all, or may be fused in the midline behind the aorta. [12] These are associated with other congenital abnormalities, such as failure of the kidneys to develop, or fused kidneys.

An expected second 17,20-lyase reaction (17α-hydroxyprogesterone → androstenedione) is mediated so inefficiently in humans as to be of no known significance. The hydroxylase reactions are part of the synthetic pathway to cortisol as well as sex hormones, but the lyase reaction is only necessary for sex hormone synthesis.
