In dense_______(i) tissues, fibroblasts and collagen are arranged differently. These tissues are present in the _____(ii)

Options

A. i-regular, ii-skin
B. i-irregular, ii-skin
C. i-regular, ii-tendons
D. i-irregular, ii-tendons

Answer

**Step-by-Step Solution:**

1. **Identify the Type of Tissue:**
The question refers to dense tissues where fibroblasts and collagen are arranged differently. The specific type of dense connective tissue being described is "irregular connective tissue." In this type of tissue, the collagen fibers are arranged in a haphazard or irregular manner, rather than in a parallel fashion.

2. **Understanding the Arrangement:**
In irregular connective tissue, the collagen fibers are not organized in a specific sequence. Instead, they are scattered and crisscrossed, providing strength in multiple directions. This arrangement allows the tissue to withstand stresses from various angles.

3. **Location of Irregular Connective Tissue:**
Irregular connective tissue is primarily found in areas that require strength and support in multiple directions. The two main locations mentioned are:
- The skin (dermis layer)
- The white portion of the eyeball (sclera)

4. **Fill in the Blanks:**
Based on the above information, we can fill in the blanks in the question:
- (i) The first blank should be filled with "irregular" to indicate the type of dense tissue.
- (ii) The second blank should be filled with "skin" to indicate where this tissue is found.

**Final Answer:**
In dense **irregular** tissues, fibroblasts and collagen are arranged differently. These tissues are present in the **skin**.
