Which one of the tissues putrefies late: Gujarat 07; WB 09; Jharkhand 11; NEET 13; JIPMER 14
First, I need to recall the order in which tissues decompose. Putrefaction starts with the most susceptible tissues. Muscles usually go first because they have high protein and are rich in bacteria. Then, internal organs like the liver and intestines follow. But some tissues resist decomposition longer. Adipose tissue, for example, is high in fat and might take longer. Also, cartilage and tendons are more resistant because they have less cellular content and more collagen.
Wait, the options aren't listed here, but the user provided the correct answer as option C. Let me think. Common options for this type of question are usually different tissues. Let's assume the options are Muscle, Adipose tissue, Cartilage, and Tendon. The correct answer would be cartilage or tendon because they have lower water content and are less prone to bacterial action.
Wait, but in standard textbooks, the order is muscle first, then organs, then fat, and finally cartilage and tendons. So if the options include cartilage, that's the late putrefying tissue. Alternatively, maybe the answer is adipose tissue. Wait, I need to be precise.
In forensic medicine, the sequence of putrefaction is muscle first, then internal organs, then fat, and lastly cartilage and tendons. So the correct answer would be cartilage. So if option C is cartilage, that's the right answer.
Now, the incorrect options: Muscle (A) putrefies early. Adipose tissue (B) comes after organs. Tendon (D) is similar to cartilage. So the explanation should clarify why cartilage is last.
Clinical pearl: Remember the order as Muscle → Organs → Fat → Cartilage/Tendon. Mnemonic: M-O-F-C.
So putting it all together, the core concept is the rate of putrefaction in different tissues. The correct answer is cartilage because of its dense structure and low water content. The wrong options are tissues that decompose earlier. The clinical pearl is the order to remember.
**Core Concept**
Putrefaction progression in postmortem tissues depends on water content, bacterial susceptibility, and structural composition. **Cartilage** and **tendons** resist putrefaction longest due to low water content, high collagen cross-linking, and reduced microbial access.
**Why the Correct Answer is Right**
Cartilage is composed of dense collagen fibers and proteoglycans in a low-water matrix. Its avascular nature limits bacterial colonization, and cross-linked collagen resists enzymatic breakdown. These properties make it the **last tissue to putrefy** after death, following fat, muscle, and organs.
**Why Each Wrong Option is Incorrect**
**Option A: Muscle tissue** – Putrefies earliest due to high water content and abundant bacterial nutrients (proteins).
**Option B: Adipose tissue** – Decomposes after muscle and organs but before cartilage due to higher lipid susceptibility to bacterial lipases.
**Option D: Tendon** – Though resistant, tendons are not as dense as cartilage, decomposing slightly faster in forensic
