Exam 6: The Endocrine System

The _____________ method of transporting hormones means that the compound remains in the cell to influence the activity of the cell in some manner.

Lactic acid is a hormone that increases circulating concentrations due to high-intensity exercise.

________________ refers to an increase in the number of receptors on the surface of target cells, making the cells more sensitive to a hormone or other molecule.

The system of testosterone regulation in females is different than the system in males.

What are the five acute resistance exercise training variables, most of which can have a profound impact on the hormonal response to exercise?

Based on the endocrine responses to resistance exercise, if muscle hypertrophy is desired, what acute training variables of resistance exercise are most responsible?

Why do some exercise/sport scientists choose to study the hormonal responses to exercise by sampling blood using an intravenous needle (catheter) inserted well before the exercise starts?

Which types of endocrine hormones can travel through the cell membrane?

When binding proteins are involved, the total hormone concentration includes the free and _______ concentrations of the hormone.

_________________ refers to hormones that are released into the bloodstream or lymph system following stimulation of the nervous system.

_________________ are the cellular structures to which the hormones bind, resulting in the appropriate action at the cell.

For a hormone to be secreted by its endocrine gland, the gland must typically receive a signal from:

Another term for negative feedback is _________ regulation.

Which of the following is an amine neurohormone responsible for much of the "fight-or-flight" response?

The hormonal response to exercise is normally intensity-dependent.

Humans experience hormonal variations based on the time of year (seasonal variation).

What are the roles of insulin and glucagon?

What tissues of the body sense levels of circulating testosterone and regulate its production?

Steroid hormones have a ______________to help them move through the target cell.

______________ is the steroid hormone that typically increases the most in response to resistance exercise.
