Lab: Exercise 27 Functional Anatomy of the Endocrine Glands

If hormones travel in the bloodstream, why dont all tissues respond to all hormones?

Ability of the target tissue to respond depends on the ability of the hormone to bind with specific receptors (proteins) on cells plasma membrane or with in the cell

Identify the endocrine organ described by the statement: Found atop the kidney

Adrenal Gland

The hormone ACTH is stimulated by

Another Hormone

The hormone T3 and T4 are stimulated by

Another hormone

The hormone TSH and FSH are stimulated by

Another hormone

The hormone testosterone is stimulated by

Another hormone

How does the hypothalamus control both Anterior Pituitary functioning?

By neuro secretions. These hormones are liberated into hypophyseal portal system and carried to cells of ant. pit. (lobe) where they control the release of ant. pit. hormones.

How does the hypothalamus control the Posterior Pituitary functioning?

By sending 2 hormones for storage to the post. pit. (lobe) Hormones transported to it via the axons of neurons in the para-ventricular and supraoptic nuclei of the hypothalamus..

Hormones responsible for each function, and the endocrine glands that produce the hormone. Drive development of secondary sex characteristics in males

Hormone: Testosterone Gland: Testes

Hormones responsible for each function, and the endocrine glands that produce the hormone. Maintenance of salt and water balance in the extracellular fluid

Hormones: ADH, and Aldosterone Glands: ADH → Posterior Pituitary Gland, and Aldosterone → Adrenal Cortex

Hormones responsible for each function, and the endocrine glands that produce the hormone. Release in response to stressors

Hormones: Cortisol, and Epinephrine Glands: Cortisol → Adrenal Cortex, and Epinephrine → Adrenal Medulla

Hormones responsible for each function, and the endocrine glands that produce the hormone. Directly responsible for regulation of the menstrual cycle

Hormones: Estrogen and Progesterone Gland: Ovaries

The hormone responsible for each function, and the endocrine glands that produce the hormone. Regulate the function of another endocrine gland

Hormones: FSH, LH, ACH, and TSH Gland: Anterior Pituitary Gland

Hormones responsible for each function, and the endocrine glands that produce the hormone. Regulate blood glucose levels; produced by the same "mixed" gland

Hormones: Insulin, and Glucagon Gland: Pancrease

Hormones responsible for each function, and the endocrine glands that produce the hormone. Directly involved in milk production and ejection

Hormones: Prolactin, and Oxytocin Glands: Prolactin → Anterior Pituitary Gland, and Oxytocin → Posterior Pituitary Gland

Hormones responsible for each function, and the endocrine glands that produce the hormone. Controls the rate of body metabolism and cellular oxidation

Hormones: T3 and T4 Gland: Thyroid Gland

The hormone insulin is stimulated by

Humoral factors (The concentration of specific non-hormonal substances in the blood or extracellular fluid)

The hormone parathyroid hormone is stimulated by

Humoral factors (the concentration of specific nonhormonal substances in the blood or extracellular fluid)

The nervous system has been compared to an airmail delivery system and the endocrine system to the Pony Express. Briefly explain this comparison.

Nervous system uses electrochemical impulses rapid control. Endocrine system more acting system uses chemical messengers.

Target Organ

Organs that respond to a particular hormone/respond depends on the ability of the hormone to bind with specific receptors occurring with in or on the cells

Identify the endocrine organ described by the following statement: Found in the pelvic cavity of the female, concerned with ova and female hormone production

Ovary

Identify the endocrine organ described by the statement: A mixed gland, located close to the stomach and small intestine

Pancreas

Identify the endocrine organ described by the following statement: Ride "horseback" on the thyroid gland

Parathyroid gland

Identify the endocrine organ described by the following statement: Found in the roof of the third ventricle

Pineal Gland

Hormone

Steroidal or amino acid based molecules released to the blood that act as chemical messengers to regulate specific body functions

Identify the endocrine organ described by the statement: Paired glands suspended in the scrotum

Testes

The hormone norepinephrine is stimulated by

The nervous system (neurotransmitters, or neurosecretions)

Identify the endocrine organ described by the following statement: Found in the upper thorax overlying the heart; large during youth

Thymus

Identify the endocrine organ described in the following statement: Located in the throat; bilobed gland connected by an isthmus

Thyroid

The hormone estrogen is stimulated by

another hormone

The hormone Calcitonin is stimulated by

humoral factors (the concentration of specific non-hormonal substances in the blood or extracellular fluid)

Chemically, hormones belong chiefly to two molecular groups, the ____ and the _____

steroids; amino acid-based molecules

Hormones responsible for each function, and the endocrine glands that produce the hormone. Regulates blood calcium levels
