OBJECTIVES
1. Identify the relationship between the hypothalamus and the pituitary gland in the
release of hormones.
2. List the functions of the major endocrine glands and hormones.
3. Explain the role of feedback mechanisms in maintaining homeostasis.
4. Compare how negative feedback and positive feedback mechanisms are used to
regulate hormone levels.
5. Summarize how antagonistic hormones work as pairs to maintain homeostasis.
NATIONAL SCIENCE EDUCATION STANDARDS
LSCell1: Cells have particular structures that underlie their functions.
LSCell2: Most cell functions involve chemical reactions.
LSCell4: Cell functions are regulated.
LSMat4: The complexity and organization of organisms accommodates the need for
obtaining, transforming, transporting, releasing, and eliminating the matter and energy
used to sustain the organism.
LSBeh2: Organisms have behavioral responses to internal changes and to external
stimuli.
ST2: Understandings about science and technology
