What a finished Unit 2 map for NU104 contains: labeled arrows from injury to the cardinal signs, an acute and a chronic branch, healing outcomes, and a short narrative key. Searches like "nu 104 unit 2 assignment example", "nu104 unit 2 sample" and "nu104 unit 2 example" land here.
What a finished NU104 Unit 2 concept map looks like
Picture a page where injury sits at the top and the cardinal signs appear roughly a third of the way down, each one tied back to the vascular event that produces it. Redness and heat hang from arteriolar dilation, swelling from leaky venules letting protein-rich fluid into the tissue, pain from mediators such as bradykinin and prostaglandins acting on nerve endings. Loss of function sits beneath swelling and pain together. Below that comes a branch point: if the stimulus clears, the map moves to resolution and repair, and if it persists, a chronic branch shows macrophages, lymphocytes and fibrosis. The healing section separates regeneration in tissues that can divide from scar formation where they cannot. A narrative of a paragraph or two restates the chain in sentences, so a grader can read it either way.
How a NU104 Unit 2 example is structured
Concept maps in this unit tend to follow a top-down or left-to-right flow, and the sample adopts whichever direction the template asks for. The first tier holds the trigger: trauma, infection, or necrotic tissue left behind by the kind of injury Unit 1 described. The second tier holds the vascular and cellular response, with separate boxes for dilation, permeability and white cell margination and emigration. Mediators sit as labels on arrows rather than as boxes of their own, because they are processes that connect events. The third tier carries the observable signs and any systemic findings, such as fever or a raised white count. The final tier handles outcome, with a fork for resolution, regeneration, scar or chronic inflammation. A legend lists abbreviations, and the accompanying narrative walks the main chain once in prose.
Mediators as arrow labels
Histamine, prostaglandins and bradykinin do their work between events, so the sample writes them onto connecting lines. A map that boxes them separately looks tidy and hides what each one actually causes.
Local and systemic tiers
Local signs come from the injured tissue, while fever, malaise and leukocytosis come from mediators reaching the circulation. Keeping these on separate tiers shows the grader that the map knows where each finding originates.
Acute versus chronic branch
The fork depends on whether the stimulus is cleared. Neutrophils dominate early, macrophages and lymphocytes take over when injury persists, and the chronic branch ends in fibrosis rather than in restored tissue.
Regeneration or scar
Healing outcomes depend on the tissue. Liver and skin epithelium can regenerate, whereas cardiac muscle and most neurons cannot, and repair there means connective tissue. A strong map names the tissue before choosing the outcome.
The narrative beneath the map
A paragraph under the diagram restates the main chain in sentences. It lets a grader confirm that each arrow was understood rather than copied, and it is often where a rubric locates its explanation criterion.
Where marks go in NU104 Unit 2
Unlabeled arrows cost the most, and in this unit they cost points on almost every branch. A line from injury to swelling says two things are related, while a line reading increased venular permeability, plasma proteins leave the vessel, water follows says why. Maps also lose credit when the cardinal signs float unattached, listed in a corner rather than linked to the vascular change behind each. Treating inflammation and infection as the same process is a common content error, since sterile injury inflames too. A missing chronic branch leaves half the unit's content off the page. Healing drawn as one outcome for every tissue misses the regeneration question. Illegible layouts where lines cross repeatedly lose marks for clarity, and maps with no narrative give the grader nothing to check the arrows against.

NU104 Unit 2 questions, answered
Does the map need a written explanation too?
Many Unit 2 prompts ask for one, and even where they do not, a short narrative protects you. It shows the grader that you understand the chain rather than having arranged terms in a pleasing order. The sample keeps its narrative to the main pathway, injury to signs to outcome, and lets the diagram carry the finer detail.
Should mediators be boxes or arrow labels?
Arrow labels, in most cases. A mediator is the reason one event produces the next, so it belongs on the line joining them. Histamine written on the arrow from mast cell activation to vasodilation tells the grader what the connection is. Where your rubric wants mediators listed separately, a legend beside the map can do that without breaking the chain.
How much of healing belongs on an inflammation map?
Enough to show that outcome depends on tissue type and on whether the stimulus clears. A fork for resolution, regeneration, scar and chronic inflammation covers most Unit 2 prompts. The phases of wound healing can sit in a small cluster at the bottom if your instructions mention them, but they rarely replace the vascular chain as the graded center.
