1: Where is \ Pituitary Gland? | The pituitary is an endocrine (hormone-producing) gland that sits just beneath the base of the brain, behind the bridge of the nose. It is very small; only about the size of a pea. | Normal gland function of Pituitary gland? | "" | - master gland of the body - produces and secretes many hormones that travel throughout the body, directing certain processes stimulating other glands to produce different types of hormones.

2: Prolactin | - Stimulates milk production from the breasts after childbirth to enable nursing -Affects sex hormone levels from ovaries in women and from testes in men | Growth Hormone (GH) | - Stimulates growth in childhood and important for maintaining a healthy body composition and well-being in adults - Affects fat distribution in the body

3: Adrenocorti -cotropin (ACTH) | - Stimulates production of cortisol by adrenal glands - "Stress hormone" - vitual to our survival because it helps to maintain blood pressure & blood glucose level | Thyroid-stimulating hormone (TSH) | - Stimulates thyroid gland and regulates body's metabolism, energy, growth, and nervous system activity - Vital for survival

4: - Regulates water balance | Antidiuretic Hormone | Luteinizing Hormone | Follicle-stimulating Hormone | - Regulates testosterone in men and estrogen in women | - Promotes sperm production and ovaries to ovulation - LH and FSH: together for normal functions of reproductive organs

5: Clinical manifestations | From compression of surrounding neural or vascular structures - Headache: Stretching of diaphragma sellae - Visual Loss: Compression of optic chiasm

6: 1) Glucocorticoids - to treat adrenal insufficiency from ACTH (hormone) deficiency 2) Levothyroxine - thyroid hormone replacement for hypothyrodism / influences growth and tissue develpment 3) Sex-appropriate hormones - for sex-hormone deficiency 4) Estrogen replacement therapy with or without progesterone - for women 5) GH replacement therapy - for children (sometimes adults), stimulates linear growth | Treatment?

7: Common Causes of dysfunction | Tumor Development: - excessive amounts of hormone - hinder other hormone production - compress surrounding tissues Genetic Mutations: - excess or deficient amount of hormone can occur

8: Hypofunction | Less stimulation of hormones than necessary: - Deficiency of one hormone = excess production of another

9: Hyperfunction | More hormones than necessary: - Tumor - Tissue oversensitivity - External Factors: medicines
