Problem :

Name three parts of the brain involved in control of the vertebrate endocrine system.

The hypothalamus, the anterior pituitary gland, and the posterior pituitary gland are all involved in the regulation of the vertebrate endocrine system.

Problem :

What is the difference between the endocrine and exocrine systems?

The endocrine system produces and transports chemical signals within the body. The exocrine system produces and transports signals outside of the body.

Problem :

What are the three types of hormones and where in the cell do they act?

Steroids are large ring molecules that bind in the cell nucleus. Peptide hormones bind to the cell surface, as do catecholamines.

Problem :

What are the different functions of the anterior and posterior pituitary glands?

The anterior pituitary produces many types of hormones, while the posterior pituitary acts mostly to store these hormones.

Problem :

Is the pituitary gland an endocrine or exocrine gland? Why?

The pituitary gland (the combined anterior and posterior pituitaries) is an endocrine gland because it secretes signal chemicals intended for other organs inside the body.
