Stress proteins (i.e. ,heat shock proteins)are manufactured by cells in response to exercise and other stresses.Importantly,increasing the cellular levels of heat shock proteins

Endocrine signaling involves the release of _________ into the bloodstream.

The most important control systems in the body are those systems that regulate a physiological variable that is required to sustain life.Which of the following control systems would likely have a large gain?

The general components of a biological control system are the

In order to maintain blood glucose homeostasis,which of the following events would likely occur in response to a significant rise in blood glucose?

The formation of mRNA in the cell is called

The term cell signaling refers to

A chemical messenger is released from one cell and stimulates nearby cells is an example of

The gain of a control system is the ability of a receptor to adapt to a repeated stimulus.

The factor that "turns on" genes to promote the production of mRNA is called a

Exercise training can improve homeostatic control via

The endocrine system plays a key role in maintaining homeostasis in the body.

Failure of a biological control system can result in disease.

The term homeostasis is defined as

The gain of a biological control system can be thought of as the

Most control systems of the body operate via

A series of interconnected components that serve to maintain a physical or chemical parameter of the body near a constant value is

Negative feedback is an important class of biological control systems in the body that serves to restore normal values of a variable to maintain homeostasis.Which of the following examples illustrate a negative feedback control system of the body?

Physiologists use the term steady state to denote

Some cells communicate by cell-to-cell contact.This type of signaling
