Chapter 4 Tissues & Epithelium Quiz

1. What is the description, function, and location of simple squamous epithelium?

DESCRIPTION: Cuboidal cells forming tubular structures. FUNCTION: Secretion and absorption. LOCATION: Sweat glands.

DESCRIPTION: Multiple layers of cylindrical cells. FUNCTION: Absorption and secretion. LOCATION: Skin.

DESCRIPTION: Stratified squamous epithelium. FUNCTION: Protection against abrasion. LOCATION: Digestive tract.

DESCRIPTION: Single layer of flattened cells, disc shaped nuclei.
FUNCTION: Allows passage by diffusion and filtration. LOCATION: Located in Kidney, glomeruli, air sacs of lungs, lining of heart, blood vessels, lymphatic vessels.

Simple squamous epithelium is characterized by a single layer of flattened cells with disc-shaped nuclei. Its main function is to allow passage by diffusion and filtration. This type of epithelium is commonly found in locations such as the kidney, glomeruli, air sacs of the lungs, lining of the heart, blood vessels, and lymphatic vessels.

Simple squamous epithelium is characterized by a single layer of flattened cells with disc-shaped nuclei. Its main function is to allow passage by diffusion and filtration. This type of epithelium is commonly found in locations such as the kidney, glomeruli, air sacs of the lungs, lining of the heart, blood vessels, and lymphatic vessels.

2. What is the characteristic of Simple Cuboidal Epithelium?

DESCRIPTION: Single layer of cube like cells, large spherical central nuclei.
FUNCTION: Secretion and absorbtion
LOCATION: Kidney tubules, ducts and secretory portions of small glands, ovary surface.

DESCRIPTION: Single layer of squamous cells, large circular central nuclei. FUNCTION: Sensory perception. LOCATION: Cornea of the eye.

DESCRIPTION: Multiple layers of cube like cells, small flattened central nuclei. FUNCTION: Protection. LOCATION: Skin epidermis.

DESCRIPTION: Single layer of column like cells, small spherical central nuclei. FUNCTION: Support. LOCATION: Small intestine lining.

Simple Cuboidal Epithelium is characterized by a single layer of cube-like cells, with large spherical central nuclei. Its main functions include secretion and absorption, and it is commonly found in kidney tubules, ducts and secretory portions of small glands, and on the surface of the ovary.

3. What is Simple Columnar Epithelium?

DESCRIPTION: Multiple layers of flat cells. FUNCTION: Protection. LOCATION: Skin.

DESCRIPTION: Single layer of tall cells with rounded nuclei.
FUNCTION: Absorption, secretion of mucus, ciliated type propels mucus.
LOCATION: non-ciliated types lines most of digestive tract; ciliated types lines small bronchi, uterine tubes.

DESCRIPTION: Pseudostratified columnar epithelium. FUNCTION: Absorption, secretion of mucus. LOCATION: Lines trachea and upper respiratory tract.

DESCRIPTION: Single layer of cube-shaped cells. FUNCTION: Secretion. LOCATION: Kidney tubules.

Simple columnar epithelium is a single layer of tall cells with rounded nuclei, found in locations that require absorption and secretion, such as the digestive tract. It can be ciliated or non-ciliated, with ciliated types propelling mucus.

Explanation

Simple columnar epithelium is a single layer of tall cells with rounded nuclei, found in locations that require absorption and secretion, such as the digestive tract. It can be ciliated or non-ciliated, with ciliated types propelling mucus.

4. What is the structure and function of Pseudostratified Columnar Epithelium and where can it be found in the body?

Simple Squamous Epithelium covering skin and providing protection.

DESCRIPTION: Single layer of cells of differing heights, some not reaching the free surface; nuclei seen at different levels. May contain goblet cells and cilia.
FUNCTION: Secretion of mucus, propulsion of mucus bu cilia.
LOCATION:Non-ciliated type in male's sperm carrying ducts. Ciliated types lines trachea and most of upper respiratory tract.

Transitional Epithelium found in the small intestine and responsible for immune defense.

Stratified Cuboidal Epithelium lining the bladder and aiding in absorption of nutrients.

Pseudostratified Columnar Epithelium is a specific type of epithelial tissue with unique characteristics and functions, different from the incorrect answers provided. It is important to understand its description, function, and location for a complete understanding of this type of tissue in the human body.

5. What type of epithelium resembles both stratified squamous and stratified cuboidal, with dome-shaped or squamous surface cells depending on degree of organ stretch?

Simple Squamous Epithelium

DESCRIPTION: Resembles both stratified squamous AND stratified cuboidal; basal cells cuboidal or columnar; surface cells DOME SHAPED or squamous (depending on degree of organ stretch, like full bladder).
FUNCTION: Stretches readily and permits distension of urinary organ by contained urine.
LOCATION: Lines ureters, bladder and part of urethra.

Pseudostratified Columnar Epithelium

Stratified Columnar Epithelium

Transitional epithelium is unique in that it can change shape to accommodate stretching in organs like the bladder, ureters, and part of the urethra. It is specifically designed to permit distension of urinary organs by allowing for easy stretching.
