Endocrine system - Coggle Diagram

- - - - (stimulates milk production and acts with LH)
    - - controlled by hypothalamus ,External secretion governs its secretion . More secretion in pregnancy to produce melanin a pigment that darkens skin. Excess is secreted in Addison's disease
    - - -[ ] released as a result of stress(cold ,heat ,pain ,fright ,infections) by hypothalamus. Excess and deficiency causes disturbance in normal adrenal functions
    - - It works with FSH to stimulate oestrogen secretion rupture of mature follicle to release egg/ovum. Causes leuitenising (yellowing) of latter and acts synergistically with prolactin to maintain corpus leuteum. ICSH in males stimulates cells of testis to secrete testosterone
    - - release is stimulated by distention of cervix ,decrease in progesterone's level in blood,neural stimuli during parturition suckling.
        Actin is on uterus during childbirth, causes milk ejection from mammary glands
    - - Secretes due to decrease in bp,blood volume, and osmotic pressure of the blood detected by osmoreceptors in hypothalamus .
        Increased levels: water reabsorption in distal nephron parts.
        deficiency: Diabetes insipidus(dilute urine great thirst)
    - - low level of thyroxine ,increased levels of TSH
      - Reaches high levels of during periods of rapid growth and development
      - acts directly on cells of thyroid gland increasing its secretion and number
