Tissues Anatomy and Physiology Questions and Answers
- 1.
How are epithelial tissues classified?
- A.
Epithelium is classified as either voluntary or involuntary
- B.
Epithelium is classified as either loose or dense
- C.
Epithelium is classified by the number of cell layers and the shape of the cells
- D.
Epithelium is classified by the presence or absence of ECM
Correct Answer
C. Epithelium is classified by the number of cell layers and the shape of the cellsExplanation
Epithelial tissues are classified based on the number of cell layers and the shape of the cells. This classification helps in identifying and categorizing different types of epithelial tissues. The number of cell layers can be simple (single layer) or stratified (multiple layers), while the shape of the cells can be squamous (flat and thin), cuboidal (cube-shaped), or columnar (tall and elongated). This classification system is important for understanding the structure and function of epithelial tissues in various organs and systems of the body.Rate this question:

You examine a tissue slide through the microscope and recognize one layer of cells that are mostly tall and elongated. You determine this tissue to be:
- A.
Simple cuboidal epithelium
- B.
Simple columnar epithelium
- C.
Simple squamous epithelium
- D.
Stratified columnar epithelium
Correct Answer
B. Simple columnar epitheliumExplanation
Based on the description provided, the tissue slide shows a single layer of tall and elongated cells. This characteristic is typical of simple columnar epithelium, which consists of a single layer of column-shaped cells. Simple cuboidal epithelium consists of cube-shaped cells, simple squamous epithelium consists of flat and thin cells, and stratified columnar epithelium consists of multiple layers of column-shaped cells. Therefore, the correct answer is simple columnar epithelium.Rate this question:

Which of the following epithelia can be keratinized?
- A.
Stratified columnar epithelium
- B.
Transitional epithelium
- C.
Stratified squamous epithelium
- D.
Simple columnar epithelium
Correct Answer
C. Stratified squamous epitheliumExplanation
The correct answer is stratified squamous epithelium. This type of epithelium is found in areas of the body that experience high levels of mechanical stress, such as the skin and the lining of the oral cavity. Keratinization is the process by which cells in the outer layers of the epithelium become filled with a protein called keratin, making them tough and resistant to abrasion. Stratified squamous epithelium can undergo keratinization, forming a protective layer on the surface of the skin or other organs.Rate this question:

Where is simple columnar epithelium located
- A.
Lining of the small intestine
- B.
Lining of the esophagus
- C.
Lining of the nasal cavity
- D.
Forming the air sacs of the lungs
Correct Answer
A. Lining of the small intestineExplanation
Simple columnar epithelium is a type of tissue that consists of a single layer of tall, column-shaped cells. It is typically found in areas of the body that require absorption and secretion, such as the lining of the small intestine. The tall and tightly packed cells of the simple columnar epithelium allow for efficient absorption of nutrients from the digested food in the small intestine. This type of epithelium also provides protection and helps in the secretion of mucus and enzymes that aid in digestion. Therefore, the correct answer is lining of the small intestine.Rate this question:

What general tissue type binds, supports and protects the body?
- A.
Connective
- B.
Epithelial
- C.
Muscle
- D.
Nervous
Correct Answer
A. ConnectiveExplanation
Connective tissue is the correct answer because it is the general tissue type that binds, supports, and protects the body. Connective tissue is found throughout the body and provides structural support to organs and tissues. It also helps in connecting different body parts, protecting delicate organs, and providing cushioning. Examples of connective tissues include bone, cartilage, adipose tissue, and blood. Epithelial tissue covers the body surfaces and lines the cavities, muscle tissue is responsible for movement, and nervous tissue is involved in transmitting signals.Rate this question:

What statement best describes dense regular collagenous connective tissue?
- A.
Dense regular collagenous connective tissue contains bundles of collagen fibers arranged haphazardly
- B.
Dense regular collagenous connective tissue contains parallel bundles of elastic fibers
- C.
Dense regular collagenous connective tissue is found in the dermis of the skin
- D.
Dense regular collagenous connective tissue forms tendons and ligaments
Correct Answer
D. Dense regular collagenous connective tissue forms tendons and ligamentsExplanation
Dense regular collagenous connective tissue forms tendons and ligaments. This tissue type is characterized by its dense arrangement of collagen fibers that are aligned in parallel bundles. Tendons connect muscles to bones, while ligaments connect bones to other bones, providing stability and support to joints. This description accurately describes the function and location of dense regular collagenous connective tissue.Rate this question:

Which division of the cranial skeleton is considered the "braincase?"
- A.
Chondrocranium
- B.
Splanchnocranium
- C.
Dermatocranium
- D.
None of the above
Correct Answer
A. ChondrocraniumExplanation
The division of the cranial skeleton that is considered the "braincase" is the chondrocranium. The chondrocranium is the part of the skull that surrounds and protects the brain, and is made up of cartilage. It forms the base and sides of the skull, providing support and protection to the brain and other cranial structures. The splanchnocranium is responsible for forming the facial bones, while the dermatocranium forms the outer layer of the skull. None of these divisions specifically refer to the braincase.Rate this question:

Which is associated with the development of the jaws
- A.
First branchial arch
- B.
Hyoid arch
- C.
Mandibular arch
- D.
Second pharyngeal arch
Correct Answer
C. Mandibular archExplanation
The mandibular arch is associated with the development of the jaws. During embryonic development, the mandibular arch gives rise to the lower jaw, or mandible, as well as other structures such as the muscles of mastication. This arch plays a crucial role in the formation and growth of the jaw, allowing for proper function and movement of the mouth.Rate this question:

Which cranial division is absent in chondrichthyans?
- A.
Chondrocranium
- B.
Splanchnocranium
- C.
Dermatocranium
- D.
Olfactory
Correct Answer
C. DermatocraniumExplanation
Chondrichthyans, which include sharks and rays, lack the dermatocranium division in their cranium. The dermatocranium is the part of the skull that forms the outer layer and provides protection to the brain. In chondrichthyans, the skull is primarily made up of cartilage rather than bone, and therefore, the dermatocranium is absent.Rate this question:

Which centrum type is characterized by a concavity on only the anterior surface?
- A.
Amphicoelous
- B.
Procoelous
- C.
Opisthocoelous
- D.
Acoelous
Correct Answer
B. ProcoelousExplanation
Procoelous is the correct answer because it is the centrum type characterized by a concavity on only the anterior surface. This means that the front part of the centrum is concave, while the back part is flat or slightly convex. This type of centrum is commonly found in certain vertebrates, such as reptiles and dinosaurs, and allows for increased flexibility and movement in the spine.Rate this question:

Which caudal fin type appears externally symmetrical, but includes longer hypurals?
- A.
Hypocercal
- B.
Heterocercal
- C.
Homocercal
- D.
Diphycercal
Correct Answer
C. HomocercalExplanation
The homocercal caudal fin type appears externally symmetrical, meaning that the upper and lower lobes of the fin are of equal size and shape. However, it includes longer hypurals, which are bony structures that support the fin. This distinguishes it from other caudal fin types such as the heterocercal, hypocercal, and diphycercal fins, which do not have longer hypurals.Rate this question:
