Unit 1 anatomy exam

Pituitary gland

Anterior & Posterior Halves

Posterior Pituitary

Oxytocin & Antidiuretic Hormone

Anterior Pituitary

Thyroid Stimulating Hormone, Growth Hormone, Prolactin, Adrenocorticotropic Hormone, Follicle Stimulating Hormone, Luteinizing Hormone

Cerebrum

Hypothalamus

Pituitary

Cerebellum

Brain stem

Spinal cord

Anterior pituitary complex

Hypothalamus

Superior hypophyseal artery

1) Hypothalamus releases hormone

Neurosecretory cells

Primary capillary plexus of hypophyseal portal system

Posterior pituitary

Secondary capillary plexus of hypophyseal portal system

2) Hypothalamus hormone stimulates pituitary to release hormones

Adrenal cortex

Growth

Kidney

Corticosteroids

Thyroid

Thyroxine

Testes

Testosterone

Ovaries

Progesterone, estrogens

Mammary glands

Thyroid Gland produces

Thyroxine (T4) via stimulation from TSH

What is T4 converted to

active form of T3 (Triiodothyronine)

Thyrotropin-releasing hormone

Dopamine

Growth hormone-releasing hormone

Somatostatin

Gonadotropin-releasing hormone

Corticotropin-releasing hormone

oxytocin

vasopressin

Melatonin

Triiodothyronine

Thyroxine

Growth hormone

Thyroid-stimulating hormone

Adrenocorticotropic hormone

Follicle-stimulating hormone

Luteinizing hormone

Prolactin

melanocyte-stimulating hormone

Oxytocin

Vasopressin

Oxytocin (stored)

Anti-diuretic hormone (stored)

Thyroid gland

Thyroid gland

Thyroid gland

Thymus gland

Parathyroid Glands secrete Parathyroid Hormone which helps

absorb Calcium from the intestines
reabsorb Calcium in the kidneys

remove Calcium from the bone with the overall effect of increasing blood Calcium levels

Parathyroid gland

Hyperparathyroid

Parathyroid Glands

Adrenal glands two sections

A Cortex & a Medulla

Cortex three regions

Zona Glomerulosa (Aldosterone), Zona Fasciculata (Cortisol), & Zona Reticularis (Androgen)

Medulla releases the Catecholamines known as

Epinephrine & Norepinephrine

Endocrine function of pancreas: 

producing Insulin & Glucagon

Exocrine function of the pancreas:

production of digestive enzymes

Adrenal gland

Superior surface of kidney

Cortex

Medulla
