Term
How many lobes are in the pituitary gland?
Definition
Two Lobes
Term
What are the names of the lobes of the pituitary gland?
Definition
The posterior pituitary (neurohypophysis)
Anterior Ptuitary
(Adenohyphophysis)
Term
How many hormones are released from the posterior pituitary?
Name them
Definition
Two
ADH and Oxytocin
Term
How many hormones are released from the anterior pituitary?
Name them.
Definition
seven
TSH, GH, ACTH, FSH, LH, PRL,MSH
Term
What hormones are released from the Thyroid gland?
Definition
T3 T4 and calcitonin
Term
Give a function of each of the thyroid hormones.
What disorder is associated with them and how are they afected?
Definition
T3, T4 affect cellular metabolism rates
Calcitonin Lowers blood Ca++ levels increases Ca++ depositing in bones
in goiter T3 and T4 are not produced, the precursor to T3 and T4 swell causing thyroid swelling
Term
What hormone(s) are released from the parathyroid glands?
Definition
Parathyroid hormone
Term
What hormone(s) are released from the parathyroid glands?
Definition
Parathyroid hormone
Term
What hormone(s) are released from the parathyroid glands?
Definition
Parathyroid hormone
Term
What hormone(s) are released from the parathyroid glands?
Definition
Parathyroid hormone
Term
Give the functions of parathyroid hormone
Definition
Increases blood Ca+ concentration by: Increased Ca++ absorption in intestine Causes kidneys to conserve Ca++ Bones release Ca++
Term
What are the two portions of the adrenal glands?
What hrmones are secreted from each?
Definition
Adrenal cortex and medulla
Medulla=E and NE
Cortex= Adosterone, Cortisol, Sex hormones
Term
What functions do the Adrenal cortex hormones serve?
Definition
Epinehphrine and Norepinephrine also known as adrenaline and noradrenaline activate the sympathetic system
Term
What functions do the adrenal medulla hormones serve
Definition
2. Aldosterone-Conserves Na+ increasing blood volume and pressure
Cortisol-Stimulates gluconeogenesis, increases use of fatty acids for energy, increases amino acid availability
Sex hormones-effect sex organs, gender and characteristics
Term
What hormones are secreted by the pancreas?
Which cells secrete them?
Definition
Glucagon- Alpha cells
Insulin-Beta cells
Somatostatin-Delta
Term
Identify the function of each of the the pancreatic endocrine hormones
Definition
Glucagon- Alpha cells- Increased blood glucose.Stimulates liver to release glycogen storesStimulates fat breakdown-non sugars to glucose Insulin-Beta cells-Cells 20X more permeable to glucoseStimulates fat storageDecreases blood sugarSomatostatin-Delta- inhibits secretion of Insulin and Glucagon
Term

2. What is the function of growth hormone?
Definition
1. Anterior Pituitary gland
2.Stimulates cell growth in size and mitosis, Promotes protein synthesis, Promotes growth of long bones
Term
1. What releases Growth hormone?
2. What is the function of growth hormone?
Definition
1. Anterior Pituitary gland
2.Stimulates cell growth in size and mitosis, Promotes protein synthesis, Promotes growth of long bones
Term
1. Where is leutinizing hormone released from?
2. What is the function of LH?
Definition
1. Anterior Pituitary gland
2. Sustains milk production in nursing
Decreases LH in men
Term
1. What releases Thyroid stimulating hormone?
2. What is th function of TSH?
3. What disorder is associated with TSH?
Definition
1. Anterior Pituitary gland
2. Controls secretions of hormones from the thyroid gland
3. High levels lead to Goiter
Term
1. What releases Thyroid stimulating hormone?
2. What is th function of TSH?
3. What disorder is associated with TSH?
Definition
1. Anterior Pituitary gland
2. Controls secretions of hormones from the thyroid gland
3. High levels lead to Goiter
Term
1. Where is ACTH released from?
2. What is the function of Adrenocorticotropic hormone?
3. Name two things that stimulate the release of ACTH
Definition
1. Anterior Pituitary gland
2. Controls secretion of adrenal cortex hormones
3. Stimulated by corticotropin releasing hormone Stress
Term
1.Where is Follicle stimulating hormone rleased?
2. What is the function of FSH?
3. What stimulates the release of FSH?
Definition
Follicle stimulating hormone
1. Anterior Pituitary gland2. Development of ovarian follicles Stimulates estrogen secretion Stimulates sperm creation3. Stimulated by GnRH gonadatropin releasing hormone
Term
1. Where is leutinizing hormone released from?
2. What is the role of LH?
3. What hormone stimulates the release of LH?
Definition
1. Anterior Pituitary gland
2. Secretion of sex hormones Egg release in women
3. Stimulated by GnRH gonadatropin releasing hormone
Term
1. What releases anti dieuretic hormone?
2. What is the role of ADH?
3. How does the hypothalamus affect ADH?
Definition
1. Posterior Pituitary gland
2. Reduces water excretion Increases blood pressure
3. Produced in hypothalamus, secreted by Pos Pit
Term

2. What is its role?
3. What triggers the release of oxytocin?
Definition
1. Posterior Pituitary gland
2. Contracts muscles in uterine walls, aids in milk production
3. Released in response to uterine and vaginal stretching and breast stimulation
