Working Through the Haspi Medical Anatomy Physiology 09b Lab Activity
I ran into this lab activity while helping a student troubleshoot their nervous system module, and honestly it's one of those assignments that looks straightforward on paper but trips people up in a few predictable ways. The activity itself covers autonomic nervous system pathways, specifically the sympathetic and parasympetic divisions, and asks you to match receptors, neurotransmitters, and organ responses. Here's how it actually plays out when you're sitting at it. Haspi Medical Anatomy Physiology 09b Lab Activity typically requires you to complete a chart or matching exercise where you identify whether a given response is mediated by sympathetic or parasympathetic input, then specify which receptor type is involved. The tricky part isn't the memorization — it's that the platform sometimes presents scenarios that overlap, like heart rate changes that could technically go either way depending on context. One thing I'd tell anyone doing this for the first time: the sympathetic division uses norepinephrine at the effector organ in most cases, except for the sweat glands where acetylcholine is the transmitter acting on muscarinic receptors. That exception comes up in the 09b worksheet and people consistently miss it because they're so focused on the general rule. I had a student who kept getting those items wrong until I made her write out the full comparison table twice by hand. The act of writing it down seemed to cement it better than any amount of screen time.

When you open the activity, you'll usually see a series of organ-level prompts. Some versions ask you to drag and drop; others are fill-in-the-blank. Either way, the core skill being tested is recognizing the functional relationship between the division, the neurotransmitter, the receptor subtype, and the physiological outcome. Start by working through the sympathetic chain systematically. Go organ by organ — heart, lungs, GI tract, eyes, blood vessels — and for each one note whether sympathetic stimulation increases or decreases activity, what receptor is primarily involved, and what the net effect is. Do the same for parasympathetic. When you've got both columns filled in, the matching questions become far less guesswork and more pattern recognition. The edge case that got me: one version of this lab included a question about pupillary constriction that listed "sympathetic stimulation" as the answer choice when the correct answer was parasympathetic. The platform had a data entry error that I confirmed by cross-referencing with the textbook companion materials. If you hit something that contradicts what you know to be true, don't just second-guess yourself immediately. Verify it against at least two sources before changing your answer. It happened more than once across different iterations of this lab.
Another practical tip that saves time: if the activity gives you a dropdown for receptor subtypes, remember that beta-1 receptors dominate cardiac tissue, beta-2 handles bronchodilation and vasodilation in skeletal muscle beds, and alpha-1 is your main player for vasoconstriction. Those three cover roughly eighty percent of the items in this lab. The rest are usually muscarinic variants or niche cases like beta-3 in adipose tissue that most introductory courses barely skim. The main limitation of this activity is that it rewards memorization more than it rewards actual understanding of why things happen. You can complete the entire worksheet with perfect accuracy and still not grasp the clinical relevance — like why a beta-blocker affects the heart the way it does, or why anticholinergic drugs cause dry mouth and tachycardia. If you're doing this for a certification program, the lab will get you through the module. But if you want to actually retain this for clinical work, you need to supplement it with case-based examples or a review of pharmacology fundamentals. That gap between lab completion and real comprehension is where most students hit a wall later on. I'd also flag that the auto-grading on some versions of this platform doesn't always accept alternate but correct phrasings. Writing "parasympathetic" when it expects "rest and digest" or vice versa depending on the version can mark you wrong even though you're right. I learned to enter answers exactly as they appear in the provided key rather than using synonyms, even when it felt redundant.

For anyone looking to download supplementary materials or check answer keys, the Haspi Medical portal is the primary source. Some students share completed worksheets on study forums, but those tend to drift between versions and can be inaccurate if the lab has been updated. The most reliable approach is to work through the activity using the attached reading materials as your reference, then compare your results against the platform's feedback after submission. That feedback loop is where the actual learning happens — not in the initial attempt. Bottom line: this lab is manageable if you approach it methodically rather than rushing through it. The autonomic nervous system isn't conceptually difficult; the issue is that it's easy to confuse the receptor types and neurotransmitter pairings under time pressure. Taking twenty minutes to build your own reference table before touching the questions will cut your completion time roughly in half and dramatically reduce errors. That's the practical takeaway from someone who's watched this go wrong dozens of times.
