How do hormones influence human behavior? (22 marks) Adrenaline comes along with a term called “fight or flight” it is used when the body is under stressful situations. It is an adaption the body human body has gone through to react to danger quickly.

A portion of the cortex labeled the Zona fasciculata is where the hormone Cortisol produced. The Zona fasciculata is primarily responsible for the production of various Glucocorticoids‚ such as Cortisol. What is it?

Once that occurs‚ the semen covers the sperm and it moves into

associated with adult males and females (such as the growth of pubic hair). While puberty involves a series of biological‚ or physical‚ transformations‚ the process can also have an effect on the psychosocial and emotional development of the adolescent.
