In the endocrine system, it asks, "describe the two major mechanisms by which hormones bring about their effect on their target tissues?"I was thinking it was polar and non polar soluble because that's the major component when it comes to how cells react to their hormones, it determines how fast the reaction time.
Hormones travel through the general blood circulation to specific sites called target tissues or (1.) Effectors , where they produce a coordinated response of the target tissues. Thus, the term endocrine (en′dō-krin), derived from the Greek words (2). _________________, meaning within, and (3) ____________, to secrete, appropriately describes this system.
Endocrine glands are not to be confused with exocrine glands. Exocrine glands have (4.) _____________ that carry their secretions to the outside of the body, or into a hollow organ, such as the stomach or intestines. Examples of exocrine secretions are saliva, sweat, breast milk, and digestive enzymes.
The study of the endocrine system, known as 5. _____________________.
Can someone answer the 2-5?
The endocrine system is composed of glands that secrete hormones that regulate the activity of different body cells. The pituitary gland is often called the "master gland" because it controls the activities of other glands.
Discuss a disorder associated with either hypo or hypersecretion of a specific hormone secreted by the pituitary gland.
Include in your discussion the answer to the following:
What effect will an increase or decrease in production have on the target organs?What signs and symptoms are associated with this condition and how is it treated?

Given what you have learned in this chapter about hormone action, interpret each of the experiments described below. Identify substance X and indicate the significance of the results.(a) Addition of epinephrine to a homogenate of normal liver resulted in an increase in the activity of glycogen phosphorylase. However, when the homogenate was first centrifuged at a high speed and epinephrine or glucagon was added to the clear supernatant fraction that contains phosphorylase, no increase in the phosphorylase activity occurred.(b) When the particulate fraction from the centrifugation in (a) was treated with epinephrine, substance X was produced. The substance was isolated and purified. Unlike epinephrine, substance X activated glycogen phosphorylase when added to the clear supernatant fraction of the centrifuged homogenate.(c)…arrow_forward
