Cards

Term
Releasing and Inhibiting Factors
Definition
Secreted from the hypothalmus, this hormone modifies activity in the anterior pituitary
Term
Growth Hormone (GH)
Definition
Secreted from the Anterior pituitary, this peptide hormone increases bone and muscle growth and increases cell turnover rate
Term
Prolactin
Definition
Secreted from the anterior pituitary, this peptide hormone stimulates milk production in the mammary glands
Term
Thyroid Stimulating Hormone (TSH)
Definition
Secreted from the Anterior Pituitary, this peptide tropic hormone increases the synthesis and release of Thyroid hormone (acts upon the thyroid)
Term
Adrenocorticotropic hormone (ACTH)
Definition
Secreted from the Anterior Pituitary, this peptide hormone increases the growth and secretory activity of the adrenal cortex
Term
Lutenizing Hormone (LH)
Definition
Secreted from the Anterior Pituitary, this peptide gonadotropin has effects in ovulation and testosterone synthesis in the ovaries and testes respectively
Term
Follicle Stimulating Hormone (FSH)
Definition
Secreted from the Anterior Pituitary, this gonadotropin peptide hormone works in the ovary in follicle development and in the testes in spermatogenesis
Term
Antidiuretic hormone (ADH) also known as vasopressin
Definition
Secreted from the Posterior Pituitary, this peptide hormone causes water retention in the kidney
Term
Oxytocin
Definition
Secreted from the Posterior Pituitary, this peptide hormone causes milk letdown in breasts and contraction in the uterus.
Term
Thyroid (T3, T4) Hormone
Definition
Secreted from the Thyroid, this amino acid derivative is necessary for physical and mental development in children and increases the basal metabolic rate and temperature in adults
Term
Calcitonin
Definition
Secreted from the Thyroid, this peptide hormone lowers serum [Ca2+] and effects the bone and kidney
Term
Parathydroid Hormone (PTH)
Definition
Secreted from the Parathyroid, this peptide hormone breaks down bone and increases serum [Ca2+] levels. This affects the bone, kidney and small intestine
Term
Thymosin
Definition
Secreted from the Thymus, this peptide hormone aids in T cell development in children
Term
Epinephrine
Definition
Secreted from the Adrenal Medulla, this amino acid derivative causes the rapid sympathetic stress response
Term
Cortisol (glucocorticoid)
Definition
Secreted from the Adrenal Cortex, this steroid is part of the long term stress response and increases blood [Glucose], increases protein catabolism, and decreases inflammation and immune activity.
Term
Aldosterone (mineralcorticoid)
Definition
Secreted from the Adrenal Cortex, this steroid increases blood pressure and increases sodium absorption in the kidney
Term
Sex steroids
Definition
Secreted from the Adrenal Cortex, this hormone is not normally important but an adrenal tumor can overproduce these, causing masculinization and feminization
Term
insulin
Definition
Secreted from the islets of Langerhans in the pancreas, this peptide hormone decreases serum [Glucose], and increases glycogen and fat storage. Often known as the 'key' to getting glucose into cells. Beta cells secrete this hormone
Term
Glucagon
Definition
Secreted from the islets of Langerhans in the pancreas, this peptide hormone secreted by alpha cells increases blood [Glucose] and decreases glycogen and fat storage
Term
Somatostatin
Definition
Secreted from the islets of Langerhans in the pancreas, this peptide hormone secreted by delta cells inhibits many digestive processes.
Term
Testosterone
Definition
Secreted from the testes, this steroid is the reason behind many male characteristics and spermatogenesis
Term
Estrogen
Definition
Secreted from the Ovaries / Placenta, this steroid is responsible for endometrial growth and female characteristics
Term
Progesterone
Definition
Secreted from the Ovaries and Placenta, this steroid is key in endometrial secretion in pregnancy.
Term
Atrial Natriuretic Factor
Definition
Secreted from the Heart, this peptide hormone acts on the kidney to increase urination and decrease blood pressure
Term
Erythopoietin
Definition
Secreted from the Kidney, this peptide hormone acts on the bone marrow to increase red blood cell synthesis
Term
The anterior Pituitary has X hormones
Definition
