Nutrient aery supplying the bone enters from which end
**Question:** Nutrient aery supplying the bone enters from which end?
**Core Concept:** Nutrient arteries are blood vessels that supply the bone with essential nutrients and oxygen. They enter the bone from one end, which is different for each type of bone.
**Why the Correct Answer is Right:**
Nutrient arteries enter the bone from the epiphysis (end) of long bones, specifically the articulating surface. In this case, the correct answer is option **B**, as it refers to the epiphysis of long bones where nutrient arteries enter.
**Why Each Wrong Option is Incorrect:**
Option **A** mentions the diaphysis (middle) of long bones, which is incorrect because nutrient arteries do not enter from this region. Option **C** refers to the shaft of short bones, also incorrect as nutrient arteries enter through the epiphysis. Option **D** refers to the base of a flat bone, which is incorrect because nutrient arteries enter the bone's surface, not the base.
**Clinical Pearl / High-Yield Fact:**
Understanding the anatomy of nutrient arteries is crucial for recognizing fractures, as the entry point of nutrient arteries often serves as a landmark for diagnosing bone injuries.
**Correct Answer:** Nutrient artery enters the bone from the epiphysis (end) of long bones.
