Detailed Solution for Animal Tissue & Integument - Question 2
Brush bordered cuboidal epithelium in the proximal part of the uriniferous tubule:
- The proximal part of the uriniferous tubule is lined by a specialized type of epithelium known as the brush bordered cuboidal epithelium.
- This type of epithelium is characterized by the presence of microvilli on its free surface, which give it a brush-like appearance under the microscope.
- The microvilli greatly increase the surface area of the cells, allowing for more efficient absorption and reabsorption of substances from the filtrate.
- The brush bordered cuboidal epithelium plays a crucial role in the reabsorption of water, glucose, amino acids, and other important solutes from the filtrate.
- It also helps in the secretion of certain substances into the tubular lumen.
- The brush bordered cuboidal epithelium is found in the proximal convoluted tubule (PCT) and the proximal straight tubule (PST) of the uriniferous tubule.
- This type of epithelium is not present in the bronchioles, testis and ovary, or other parts of the nephrons in the kidney.
Conclusion:
The brush bordered cuboidal epithelium is specifically found in the proximal part of the uriniferous tubule. It is characterized by the presence of microvilli on its free surface, which enhance its absorptive and secretory functions.

Detailed Solution for Animal Tissue & Integument - Question 6
Explanation:
The columnar epithelium bearing microvilli is present in the intestine to increase the absorptive surface area. This type of epithelium is known as brush bordered cuboidal epithelium. Here is a detailed explanation:
Intestine and Absorption:
- The intestine is a part of the digestive system responsible for the absorption of nutrients from the food we consume.
- To efficiently absorb nutrients, the intestine has a large surface area, which allows for a greater contact between the nutrients and the epithelial cells.
Columnar Epithelium:
- The epithelial lining of the intestine is composed of columnar epithelial cells.
- These cells are elongated and arranged in a single layer.
- The columnar epithelium provides a protective barrier and facilitates the absorption of nutrients.
Microvilli:
- Microvilli are tiny finger-like projections present on the surface of columnar epithelial cells.
- They greatly increase the surface area available for absorption.
- Each cell may have hundreds to thousands of microvilli, forming a brush-like border on the apical surface of the epithelium.
- The microvilli increase the absorptive surface area of the intestine, allowing for efficient absorption of nutrients.
Brush Border Cuboidal Epithelium:
- The columnar epithelium with microvilli is specifically called brush bordered cuboidal epithelium.
- This type of epithelium is found in the small intestine, particularly in the region called the brush border.
- The brush border increases the absorptive capacity of the intestine, enabling the efficient absorption of nutrients such as carbohydrates, proteins, and lipids.
Conclusion:
- The presence of columnar epithelium with microvilli, known as brush bordered cuboidal epithelium, in the intestine is essential for increasing the absorptive surface area.
- This adaptation allows for efficient absorption of nutrients and is crucial for proper digestion and nutrient uptake in the body.

Fibrogen converted into fibrin in the presence of

Detailed Solution for Animal Tissue & Integument - Question 20
Explanation:
The process of converting fibrogen into fibrin involves the action of certain enzymes called coagulation factors. Specifically, it is the action of thrombin that leads to the conversion of fibrogen into fibrin. Here is a detailed explanation of the process:
1. Coagulation Cascade:
- The conversion of fibrogen into fibrin is part of the coagulation cascade, which is a complex series of reactions that occur to form a blood clot.
- The coagulation cascade involves the activation of various coagulation factors, which eventually leads to the formation of thrombin.
2. Thrombin Formation:
- Thrombin is formed from its precursor, prothrombin, through a series of enzymatic reactions.
- The activation of prothrombin requires the presence of factors such as factor Xa, factor Va, calcium ions, and phospholipids.
- Once activated, prothrombin is converted into thrombin.
3. Conversion of Fibrogen into Fibrin:
- Thrombin plays a crucial role in the conversion of fibrogen into fibrin.
- Thrombin acts on fibrinogen, a soluble plasma protein, and cleaves specific peptide bonds within its structure.
- This cleavage leads to the formation of fibrin monomers, which then polymerize to form a fibrin clot.
4. Fibrin Thread Formation:
- The fibrin monomers undergo a process called polymerization, where they align and cross-link with each other.
- This polymerization process results in the formation of a fibrin network, also known as fibrin threads.
- The fibrin threads form a meshwork that traps platelets and red blood cells, leading to the formation of a stable blood clot.
In conclusion, the conversion of fibrogen into fibrin occurs in the presence of thrombin. Thromboplastin, fibrin thread, and none of the above options do not directly participate in this conversion process.

In skin upper layer called as epidermis formed of 

Detailed Solution for Animal Tissue & Integument - Question 23

The uppermost layer of the skin is called the epidermis, which is responsible for protecting the underlying layers and regulating the loss of water from the body. The epidermis is composed of different types of cells, including epithelial cells. The correct answer to the given question is B: Keratinized stratified squamous epithelium. Here is a detailed explanation:
Epidermis composition:
- The epidermis is composed of several layers or strata.
- The deepest layer is the stratum basale, followed by the stratum spinosum, stratum granulosum, and stratum corneum.
- The stratum corneum is the outermost layer of the epidermis and is responsible for the skin's barrier function.
Keratinized stratified squamous epithelium:
- The epidermis is primarily composed of keratinocytes, which are specialized epithelial cells.
- Keratinocytes in the stratum corneum are flat, scale-like cells that are constantly shed and replaced.
- These cells are tightly packed and contain a protein called keratin, which provides strength and waterproofing to the skin.
- The stratum corneum is composed of multiple layers of these keratinized, flattened cells, forming a barrier against environmental factors.
Other options:
Just to provide a comparison, here are the explanations for the other options:
A: Cuboidal epithelium
- Cuboidal epithelium is composed of cube-shaped cells.
- This type of epithelium is not found in the epidermis but is present in other tissues and organs, such as the lining of kidney tubules.
C: Columnar epithelium
- Columnar epithelium is composed of tall, elongated cells.
- This type of epithelium is also not found in the epidermis but is present in the lining of the digestive tract, respiratory tract, and other organs.
D: Keratinized columnar epithelium
- Keratinized columnar epithelium is not a recognized type of epithelium.
- Columnar epithelium can be keratinized in certain conditions, such as squamous metaplasia, but it is not a normal component of the epidermis.
In conclusion, the upper layer of the skin, called the epidermis, is composed of keratinized stratified squamous epithelium. This structure provides protection, waterproofing, and a barrier function to the skin.
