The hormone leptin is secreted by the

adipose tissue

Target cells of hypothalamic releasing and inhibiting hormones are located in the

anterior pituitary

Steroid hormones

are structurally similar to cholesterol

The release of parathyroid hormone is controlled by

blood calcium ion levels

Parathyroid hormone stimulates the kidneys to form

calcitriol

Peptide hormones are

composed of chains of amino acids

Cells of the adrenal cortex produce

corticosteroids

What primarily targets the gonads?

follicle-stimulating hormone

Hormones from the _______, which travel I the hypophyseal portal vessels, alter the activity of the anterior pituitary

hypothalamus

Unlike the hormones, T3 and T4 hormones require _______ for production.

iodine

The nervous system

is ideal for crisis management

The target organs for the parathyroid hormone and calcitonin are

kidneys, bone, and digestive system

The posterior pituitary gland stores

oxytocin (OT)

The hormone that causes the activation of osteoclasts is

parathyroid hormone

The hormone that inhibits osteoblasts is

parathyroid hormone

The endocrine system

relies on the release of chemicals that bind to target cells

Peripheral structures sensitive to the presence of hormones are called

target cells

Which endocrine gland stores its hormone in follicle cavities?

thyroid

Triiodothyronine is a hormone secreted by the

thyroid gland

Thyroid hormones are derived from the amino acid

tyrosine

Disorders associated with thyroid hormone excess have symptoms related to

weight loss
