Where is the pituitary gland located?

At the base of the brain.

How does the pituitary gland coordinate hormonal responses as a master gland?

In response to body conditions, it releases hormones into the blood. These stimulate other endocrine glands to release hormones that produce effects in the body.

How do signals travel in nervous control compared with hormonal control?

• Nervous control: signals travel along nerves.
• Hormonal control: hormones travel in the blood to target organs.

How does the speed of action differ between nervous and hormonal control?

Nervous control acts rapidly; hormonal control generally acts more slowly.

How does the duration of effects differ between nervous and hormonal control?

Nervous effects are generally short-lived; hormonal effects are generally longer-lasting.
