1.
The parietal and visceral pleura
Correct Answer
B. Secrete small amounts of serous fluid
Explanation
The parietal and visceral pleura are not mucous membranes, as they are actually thin membranes that line the lungs and chest cavity. They do secrete small amounts of serous fluid, which helps to lubricate the lungs and reduce friction during breathing. They are not located in the abdominal cavity, but rather in the thoracic cavity. They also do not surround the heart, but rather surround the lungs.
2.
Epithelial tissue
Correct Answer
B. Forms large continuous sheets of tissue
Explanation
Epithelial tissue is a type of tissue that forms large continuous sheets in the body. It covers the surfaces of organs, lines body cavities, and forms the outer layer of the skin. This tissue is made up of closely packed cells with very little intercellular material between them. The cells are tightly connected to each other, forming a barrier that protects underlying tissues and organs. This arrangement allows epithelial tissue to efficiently carry out functions such as absorption, secretion, and protection. Therefore, the statement "forms large continuous sheets of tissue" accurately describes epithelial tissue.
3.
Glandular tissue
Correct Answer
B. Arises from epithelial tissue
Explanation
Glandular tissue is a type of tissue that arises from epithelial tissue. Epithelial tissue is the lining of organs and body cavities, and it is responsible for the secretion and absorption of substances. Glandular tissue is specialized to produce and secrete substances such as hormones, enzymes, and sweat. It is found in various organs throughout the body, not just within the abdominal organs. Therefore, the correct answer is that glandular tissue arises from epithelial tissue.
4.
Mucous membrane
Correct Answer
C. Lines the respiratory tract
Explanation
The correct answer is "lines the respiratory tract." Mucous membrane is a type of tissue that lines various body cavities and structures, including the respiratory tract. It helps to protect and lubricate the respiratory system by producing mucus, which traps foreign particles and helps to humidify the air we breathe.
5.
Squamous, cuboidal, and columnar
Correct Answer
C. Are shapes of epithelial tissue.
Explanation
The answer "are shapes of epithelial tissue" is correct because squamous, cuboidal, and columnar are terms used to describe the different shapes of epithelial cells. Squamous cells are flat and thin, cuboidal cells are cube-shaped, and columnar cells are tall and rectangular. These shapes reflect the different functions and locations of epithelial tissue in the body.
6.
Simple and stratified
Correct Answer
A. Refer to the layers of epithelial tissue
Explanation
The terms "simple" and "stratified" are used to describe the layers of epithelial tissue. Epithelial tissue is a type of tissue that covers the surfaces of organs, lines body cavities, and forms glands. Simple epithelial tissue consists of a single layer of cells, while stratified epithelial tissue consists of multiple layers of cells. These terms help to classify and describe the structure and function of different types of epithelial tissue in the body.
7.
Which of the following membranes is confined to the thoracic cavity?
Correct Answer
D. Pleurae
Explanation
The correct answer is pleurae. The pleurae are a pair of serous membranes that line the thoracic cavity and cover the lungs. They help to protect and lubricate the lungs during respiration. The meninges are membranes that surround and protect the brain and spinal cord. The peritoneum is a membrane that lines the abdominal cavity. Synovial membranes are found in joints and produce synovial fluid to lubricate and cushion the joint surfaces.
8.
Because this type of tissue is so thin, it is concerned primarily with the movement of various substances across the membranes from one body compartment to another.
Correct Answer
C. Simple squamous epithelium
Explanation
Simple squamous epithelium is the correct answer because it is a thin tissue that is specialized for the movement of substances across membranes. This type of epithelium is found in areas where diffusion and filtration occur, such as the lining of blood vessels and air sacs in the lungs. Its thinness allows for efficient and rapid exchange of gases, nutrients, and waste products between different body compartments.
9.
Which of the following is most related to glandular epithelium?
Correct Answer
A. Simple cuboidal epithelium
Explanation
Glandular epithelium is a type of epithelial tissue that is specialized in producing and secreting substances. It is composed of cells that are cuboidal or columnar in shape and form the lining of glands. Simple cuboidal epithelium is the most related option because it shares the same shape and function as glandular epithelium. It is found in glands such as the thyroid, pancreas, and salivary glands, where it facilitates the secretion of hormones, enzymes, and other substances. The other options, skeletal, cardiac, and smooth muscles, tendons, ligaments, and adipose tissue, are not directly related to glandular epithelium.
10.
Which of the following is related to endocrine glands?
Correct Answer
C. Ductless glands
Explanation
Ductless glands are related to endocrine glands because endocrine glands are a type of ductless gland. Endocrine glands secrete hormones directly into the bloodstream, rather than through ducts, and these hormones regulate various bodily functions. Therefore, the correct answer is "ductless glands."
11.
In which type of tissue is the intercellular matrix hardest?
Correct Answer
B. Bone
Explanation
The intercellular matrix in bone tissue is the hardest compared to the other options. Bone tissue is composed of cells called osteocytes embedded in a matrix of collagen fibers and mineral salts, primarily calcium and phosphate. This combination of organic and inorganic components gives bone tissue its strength and hardness, making it the correct answer.
12.
Which of the following is most descriptive of cartilage?
Correct Answer
C. Hyaline and elastic
Explanation
Cartilage is a type of connective tissue that is characterized by its firm and flexible matrix. It is composed of cells called chondrocytes embedded in a matrix that contains collagen fibers. Hyaline and elastic are types of cartilage that describe the specific composition and arrangement of the matrix. Hyaline cartilage has a smooth and glassy appearance and is found in areas such as the nose, trachea, and joints. Elastic cartilage contains elastic fibers in addition to collagen fibers, providing it with even more flexibility. Therefore, the answer "hyaline and elastic" is the most descriptive of cartilage.
13.
Which of the following does not appear in the thoracic cavity?
Correct Answer
D. Peritoneal membrane
Explanation
The peritoneal membrane does not appear in the thoracic cavity. The thoracic cavity is located in the chest region and contains organs such as the heart, lungs, and esophagus. The peritoneal membrane, on the other hand, is found in the abdominal cavity and lines the abdominal organs. Therefore, it does not appear in the thoracic cavity.
14.
Which of the following best describes scar tissue?
Correct Answer
D. Fibrosis
Explanation
Scar tissue is best described as fibrosis. Fibrosis refers to the formation of excessive fibrous connective tissue in response to injury or inflammation. This tissue is different from the normal tissue and lacks the functionality of the original tissue. Scar tissue is formed during the healing process of a wound or injury and helps to repair and strengthen the damaged area. It is characterized by its dense, tough, and less flexible nature compared to normal tissue.
15.
Which of the following are described as parietal and visceral?
Correct Answer
B. Serous membrane
Explanation
The serous membrane is described as both parietal and visceral. The parietal layer lines the walls of body cavities, while the visceral layer covers the organs within those cavities. This arrangement allows the serous membrane to provide protection and reduce friction between the organs and the cavity walls.
16.
This condition is due to prolonged pressure that causes a decrease in the blood supply to the tissues.
Correct Answer
C. Decubitus ulcer
Explanation
Decubitus ulcers, also known as pressure ulcers or bedsores, occur when there is prolonged pressure on a particular area of the body, leading to a decrease in blood supply to the tissues. This lack of blood flow causes tissue damage and can result in the formation of an ulcer. Therefore, the given explanation aligns with the correct answer, decubitus ulcer.
17.
Which word is most descriptive of gangrenous tissue?
Correct Answer
A. Necrotic
Explanation
Necrotic is the most descriptive word for gangrenous tissue because gangrene is a condition where the tissue dies and becomes necrotic due to lack of blood supply. Scar, fibrotic, and malignant do not specifically describe the characteristic of tissue death that is associated with gangrene.
18.
Why do tissues become stiffer and less efficient with aging?
Correct Answer
C. There is a decrease in collagen and elastin in connective tissue.
Explanation
As we age, the connective tissue in our body, which includes collagen and elastin, starts to decrease. Collagen provides strength and support to tissues, while elastin allows them to stretch and recoil. The decrease in these proteins leads to a loss of elasticity and flexibility in the tissues, causing them to become stiffer. This can affect various organs and systems in the body, leading to decreased efficiency in their functioning.
19.
This person "has heart".
Correct Answer
C. Perry Cardium
Explanation
This person "has heart" refers to someone who is passionate, determined, and possesses a strong sense of commitment. The name "Perry Cardium" is a play on words, as "cardium" is a term related to the heart. Therefore, the correct answer implies that Perry Cardium embodies the qualities of having heart.
