A handy glos­sary of terms for un­der­stand­ing en­docrinol­ogy

ADREN­A­LINE

Adren­a­line is one of the most fa­mil­iar hor­mones and is famed for the ‘buzz’ it gives when re­leased dur­ing fright­en­ing or ex­cit­ing mo­ments.

EN­DOCRINE SYS­TEM 2

Hu­mans have at least 80 known hor­mones and 10 hor­mone-pro­duc­ing glands. The release of hor­mones, their ef­fects, and their in­ter­ac­tion with each other is known as the en­docrine sys­tem.

HOME­OSTA­SIS 3

Hor­mones play a key role in the body’s con­stant main­te­nance of a stable in­ter­nal en­vi­ron­ment, known as home­osta­sis.

HOR­MONE

Hor­mones are chem­i­cals re­leased by the body to con­trol pro­cesses in­clud­ing di­ges­tion, me­tab­o­lism, res­pi­ra­tion,sleep, re­pro­duc­tion, mood and growth, to name a few. They travel through the blood and bind to spe­cific re­cep­tors on the tar­get cell, trig­ger­ing a change in cell func­tion.

HPA AXIS 5

This stands for the hy­potha­la­mic– pi­tu­itary–adrenal axis, a com­plex sys­tem in­clud­ing the hy­po­thal­a­mus, the adrenal and pi­tu­itary glands, and many hor­mones.
