Endocrine glands and signaling
Tue, Mar 23, 2027 · Week 10 · Human Anatomy & Physiology (Human Body Systems)
Today's goal: Map the major endocrine glands and the hormones they secrete using teacher notes and the PLTW online task.
This is a model of the work you should turn in today. Use it to check your own: match the structure and the level of detail, do not copy it. Your data and wording should be your own.
Annotated glands and primary hormones:
- Pituitary: growth hormone (also signals other glands).
- Thyroid: thyroid hormone (sets metabolic rate).
- Pancreas: insulin (and glucagon) for blood sugar.
- Adrenal glands: adrenaline (the stress response).
Vocabulary in my own words:
- Hormone: a chemical messenger that travels in the blood to change how a distant organ works.
- Target cell: the specific cell a hormone is meant to affect.
- Receptor: the matching dock on a target cell that the hormone binds to; without the right receptor, the hormone has no effect on that cell.
My lingering question: how does one gland (the pituitary) control several others at once?
| Gland | Primary hormone | Main job |
|---|---|---|
| Pituitary | Growth hormone | Growth, signals other glands |
| Thyroid | Thyroid hormone | Sets metabolic rate |
| Pancreas | Insulin | Lowers blood glucose |
| Adrenal | Adrenaline | Stress response |
This model shows the level of evidence and organization needed to complete: An annotated body diagram labeling at least four endocrine glands with their primary hormones, plus student-worded definitions of hormone, target cell, and receptor.
- Define the term in plain scientific language.
- Connect it to the current investigation.
- Use it accurately in a new example or contrast.
Keep the structure. Replace the question, facts, measurements, and evidence. Then recheck units, vocabulary, and whether the conclusion goes beyond the evidence.
Also due today: Submit your annotated diagram on Schoology.

Claim ceiling: Today's evidence supports a classroom claim about today's lesson. It cannot prove causation, diagnose a real patient, or justify action outside this room.
One exam-style question that uses exactly what you practiced today. Try it before you reveal the answer, then read why each choice is right or wrong.
Tap an answer to see the full explanation. Nothing is recorded or graded.
It builds this reusable test skill: Matching endocrine glands to the hormones they secrete and the receptor concept.
- Name the concept or data pattern being tested.
- Cross out choices that violate that rule or the evidence.
- Justify the best remaining choice before checking the answer.
