ADRENAL GLAND & HORMONES
It is an Endocrine gland It also know Suprarenal glands Sit at the top of the kidneys It has Right handed triangular shaped
andLeft handed semilunar shaped
It is responsible for releasing hormones
introduction
It has two distinct parts
Outer adrenal cortex Inner adrenal medulla
ADRENAL GLAND
Hormone secreted by adrenal cortex called Corticoids
Adrenal cortex is divided into 3 layers1. Zona glomerulosa(outer layer)2. Zona fasciculata(middle layer)3. Zona reticularis(inner layer)
Adrenal cortex
Hormone secreted by Zona glomerulosa mineralocorticoids mainly aldosterone
Functions of aldosterone: salt and water balance in body,Reabsorb sodium iones and water,Excretion of k+ and phosphate iones Deficiency:Addison’s disease
Adrenal cortex
Hormones secreted by Zona fasciculata
Gluco corticoids Cortisol, Cortisone, corticosterone Functions : Increases blood glucose level, Promote gluconeogenesis, Stimulates RBC production, Breaks down Protiens & Fats, Stores glycogen in liver , Produces anti inflammatory reactions & suppresses the immune response Deficiency :Cushing’s syndrome
Adrenal cortex
Hormones secreted by Zona reticularis
Gonado corticoids Androgen & Oestrogen Functions :Helps growth & functions of sex
organs Masculinisation - females Gynaecomastia - males
Adrenal cortex
Hormones secreted by Adrenal medulla are Adrenaline & Noradrenaline
Catecholamines Emergency hormones or Hormones of fight / flight Secreted in response to stimulation by sympathetic
nerve Functions : Increases heart beat ,Increase Pupilary
dilation ,Piloerection ,Sweating,Increase strength of heart contraction & rate of respiration , Breakdown of glycogen resulting in an increased concentration of glucose in blood, Breakdown of lipids & proteins,Increase Blood pressure,Increase blood supply to the extrimities
ADRENAL MEDULLA
They modulate the functioning of every tissues , organ , glands
Have important effects on the way you think and feel
Enable your body to deal with stress from every possible source , ranging from injury and disease
To keep your body’s reactions to stress in balance so that they are appropriate and not harmful
CONCLUSION
Thank
