Considering use of the zoom function Which of the following processes does the adrenal medulla help to regulate? The "fight or flight" response Which of the following statements regarding adrenal gland sonography is correct? Echogenic fat and overlying bowel gas can make visualizing the adrenal gland difficult. Trying different scanning approaches and positioning of patients (e.g., lateral decubitus) False Which of the following techniques can help to visualize the adrenal glands with sonography? -Using the highest frequency probe possible that affords adequate tissue penetration True Both left and right suprarenal veins typically drain directly into the inferior vena cava. Both norepinephrine and epinephrine are part of the "fight-or-flight" response of the sympathetic nervous system.Despite observing optimal scanning technique and transducer selection, sonographic visualization of normal adrenal glands in many adult patients remains difficult. The chromaffin cells of the adrenal medulla also releases norepinephrine, which affects the amygdala, and impacts attention and responses. Within it are chromaffin cells, which release epinephrine, which takes part in regulating metabolism, heart rate, vasodilation and vasoconstriction. The adrenal medulla is at the center of the adrenal gland, and is connected to the sympathetic division of the autonomic nervous system.
For females, the zona reticularis is the only source of male sex hormones, while males can also produce them in the testicles. The adrenal cortex is also a secondary source of male sex hormones, as the innermost layer, the zona reticularis, produces DHEA and androstenedione, which are sources of conversion to DHA and testosterone. The middle layer, the zona fasciculata, produces and secretes glucocorticoids, including cortisol, which is involved in glucose metabolism and the stress response mechanism. The outermost layer, the zona glomerulosa, releases aldosterone, which increases water and salt retention in the kidneys. The cortex has three layers, the zona glomerulosa, zona fasciculata, and zona reticularis. The adrenal cortex runs along the outer edge of the adrenal gland and is the primary section involved in stress response. The adrenal glands are endocrine glands that sit on top of the kidneys and take part in the stress response pathway, secondary production of androgens, and blood osmoregulation.
