Course: Anatomy & Physiology I (BIOL 2301 + BIOL 2101) · Silver Oak University (fictional sample) · Prof. Navarro
Module: Week 1 of 16 · Fall 2026 · in-person, two 75-minute lectures + one weekly lab
Objective covered: Objective 1 — Use anatomical terminology, explain the levels of organization and the characteristics of life, and describe how the body maintains homeostasis.

This file holds two pieces: (A) the Module 1 Overview page ("Start Here") and (B) the Welcome Announcement that drips out when the module opens. Dates below assume a Tuesday/Thursday lecture pattern with Week 1 meeting Tue Sep 1 and Thu Sep 3, a lab that same week, and end-of-week work due Sunday Sep 6, 11:59 p.m. Adjust the day-of-week and times to match your section.

(A) Module 1 Overview — Start Here

Welcome to Week 1: The Language and Logic of the Body

This is your home base for the week. Read it first, then work the checklist below from top to bottom. Everything you need is linked inside the module.

This week is the foundation the whole course — and your clinical training — is built on. Before we study a single bone or nerve, we have to do two things every health professional does without thinking: describe a location on the body precisely, and understand how the body keeps itself in balance. You already have everyday words for the body ("the front of the leg," "near the top"), and A&P's job is to replace the vagueness with one shared, unambiguous language — and to introduce the single most important idea in physiology: homeostasis.

The week's big question

"How do we describe any spot on the body without ambiguity — and how does the body hold itself steady when the world keeps changing?"

By Friday you'll tell anatomy from physiology, climb the levels of organization, use the directional terms / planes / cavities correctly, and explain how a feedback loop keeps you alive.

By the end of this week, you can…

Use this as a checklist. If you can do all four out loud, you're ready for the quiz.

• [ ] Distinguish anatomy from physiology, list the characteristics of life and the body's survival needs, and climb the levels of organization (chemical → cellular → tissue → organ → organ system → organism).
• [ ] Explain homeostasis and trace a negative-feedback loop (receptor → control center → effector), and tell negative feedback from positive feedback.
• [ ] Use the directional terms correctly — superior/inferior, anterior/posterior, medial/lateral, proximal/distal, superficial/deep — starting from anatomical position.
• [ ] Name the body planes (sagittal, frontal, transverse) and the body cavities (dorsal: cranial + vertebral; ventral: thoracic + abdominopelvic, split by the diaphragm).

What's due this week, and when

Work these in order — each one gets you ready for the next.

Heads-up on the AI tools: you'll use a chatbot to draft and explain, and then you judge its work against what we cover in class. Chatbots routinely flip a directional term (calling the thumb "medial"), mislabel a structure, or reverse a feedback loop. Catching the model is the point — in the tutorial, the assignment, and the lab.

Late policy reminder: 10% off per day late. If life happens, reach out before the deadline — I'd much rather hear from you early.

How to succeed this week

• Lead with the idea, not the jargon. Every term this week is a plain-English idea first (superior just means "toward the head"; homeostasis just means "keeping the inside steady"). The vocabulary comes after the picture clicks.
• Memorize two tiny hooks. "Anatomy is the what's there; physiology is the what it does." And "Negative feedback reverses the change; positive feedback amplifies it."
• Always start from anatomical position. Standing, palms forward — that's why the thumb is lateral even though it feels like it's on the inside. Every directional term assumes this starting pose.
• Build the body's "address system" once. Plane (how it's sliced), cavity (which space it's in), direction (where relative to something else). Do it on one structure and the rest of the term gets easier.
• Treat the chatbot as a smart intern, not an oracle. It drafts; you check. That habit is the whole semester in miniature — and in the clinic, the stakes for catching an error are real.

You don't need any background for this week — just curiosity about your own body and a willingness to be precise. Come to class ready to argue about whether your thumb is medial or lateral. See you Tuesday.

(B) Welcome Announcement — Module 1

Release setting: post on the module's start day (offset = 0 days), i.e., Tue Sep 1, 2026 — not before. If your platform won't preserve the scheduled date on import, post this as a draft labeled "Release: Tue Sep 1."

Subject: Welcome to Week 1 — is your thumb medial or lateral? 🩻

Hi everyone, and welcome to Anatomy & Physiology I!

Quick warm-up before we start: in anatomical position, is your thumb on the medial (inner) or lateral (outer) side of your hand? Most people say medial — and most people are wrong, because "anatomical position" means palms facing forward, which rotates the thumb to the outside. That little puzzle is our way in: in this course, everyday words like "inner" and "near the top" get replaced by one precise, shared language that every nurse, tech, and therapist uses.

This week — Body Organization, Homeostasis & Anatomical Terminology — we tackle the big question: How do we pin down any location on the body without ambiguity, and how does the body hold itself steady when the world keeps changing? By Friday you'll tell anatomy from physiology, climb the levels of organization, use the directional terms and planes and cavities, and explain the one idea the rest of physiology rests on: homeostasis.

Three things not to miss:
1. Lecture Tutorial 1 — work through the week's ideas with one approved chatbot (Gemini, Claude, or ChatGPT) and submit the share link. You'll catch the model's mistakes, not just trust it. Due Sun Sep 6.
2. Lab 1 ("Map the Body"), Quiz 1, Discussion 1, and Assignment 1 also close Sun Sep 6 — the lab uses a free virtual anatomy atlas, so start early and have fun exploring.
3. Open the Start Here page first — it lays out everything in order with due dates.

One promise: this is a course about how the body is built and how it works — not about memorizing a glossary you'll forget. We lead with plain-language ideas every single week, and we tie every structure to what it does. By Friday, the next time someone describes an injury vaguely, you'll know exactly how to pin it down: which side, which plane, which cavity, proximal or distal to what?

Bring your curiosity (and your own two hands) to class on Tuesday.

See you soon,
Prof. Navarro
