What tissue type forms most of the dermis?
A. Stratified columnar epithelium
B. Adipose tissue
C. Dense irregular connective tissue
D. Stratified squamous epithelium
Answer (2)
The tissue type that forms most of the dermis is C. Dense irregular connective tissue. This tissue provides strength and elasticity to the skin and contains various components essential for skin functions. The dermis plays a crucial role in protecting the body and supporting the epidermis.

The question is asking about the type of tissue that makes up most of the dermis, a layer of skin.
The dermis is one of the three main layers of skin, located between the epidermis (the outermost layer) and the hypodermis (beneath the dermis). It provides strength and flexibility to the skin.
Let's look at each of the options:
(A) Stratified columnar epithelium - This type of tissue is a multi-layered epithelium with column-shaped cells, not typically found in the dermis.
(B) Adipose tissue - This is a form of loose connective tissue that stores fat and acts as insulation, but it is primarily found in the hypodermis, not the dermis.
(C) Dense irregular connective tissue - This type of connective tissue has collagen fibers that are arranged in a chaotic or irregular pattern, which gives the dermis its strength and resilience. This is the main tissue type in the dermis.
(D) Stratified squamous epithelium - This multi-layered epithelium with flat cells is part of the epidermis, not the dermis.
Therefore, the correct answer is (C) Dense irregular connective tissue. This tissue type provides the skin with its strength, allowing it to withstand pressure from different directions.
In summary, the dermis is primarily composed of dense irregular connective tissue, which gives it durability and flexibility.
