Menstrual cramps are caused by prostaglandins which are both produced by and affect the uterus. Because they are produced by and affect the same area of the body they are considered

Local hormones

Thyrotropin-releasing hormone (TRH) is released from the hypothalamus in which of the following stimuli

Low body temperature and a decreased level of thyroid hormone in the blood

The endocrine system has many functions including

Medulla

water soluble hormones bind to their target cell's receptors found

On the surface of the plasma membrane

Eicosanoids are locally acting hormones. If they target cells neighboring from which they were released, this is an example of Stimulation

Paracrine

The Glands are located on the posterior surface of the thyroid gland

Parathyroid gland

Also known as the hypophysis, lies inferior to the hypothalamus

Pituitary gland

The Gland, also known as the hypophysis, lies inferior to the hypothalamus

Pituitary gland

The hypothalamus communicates with the anterior pituitary gland by the way of the hypothalamus hypophyseal System

Portal

Which are actions by which the hypothalamus directly regulates endocrine activity?

Producing two hormones that are stored in the posterior pituitary gland Producing regulatory molecules that either stimulate or inhibit the anterior pituitary gland

Because of their structure, water soluble hormones bind a receptor on the cell membrane initiating a series of biochemical events across the membrane known as

Signal pathway

Rank the half-life of the following types of hormones in order from shortest to longest

Small water-soluble, large water-soluble, lipid soluble

Under the microscope, the gland is composed of spherical structures called follicles

Thyroid

THR travels through the portal system from the hypothalamus to the anterior pituitary gland causing the release of

Thyroid stimulating hormone

True or false: Insulin promotes lipid storage

True

The anterior pituitary gland is also referred to as the

adenohypophysis

The majority of the pituitary gland is composed of the

adenohypophysis
