Concept explainers
Given these characteristics:
(I) capable of contraction
(2) covers free body surfaces
(3) lacks blood vessels
(4) composes various glands
(5) anchored to connective tissue by a basement membrane
Which of these are characteristics of epithelial tissue?
a. 1.2,3 c. 3.4.5 e. 2,3.4,5
b. 2,3,5 d. 1,2,3,4
Introduction:
The four basic tissue types are epithelial, muscular, connective, and nervous tissue. The skin is composed of epithelial tissue. The principal shapes of the epithelial cells are cuboidal, squamous, and columnar.
Answer to Problem 1RAC
The correct answer is option (e) 2,3,4,5.
Explanation of Solution
Explanation for the correct answer:
Option (e) 2,3,4,5. The epithelial tissue plays an important role in covering the body tissues. It is not vascularized and does not contract. The epithelial tissue is also responsible for the formation of some glands. The basal part of epithelium adheres to a basement membrane, which anchors the connective tissue to epithelial tissue. So, the correct answer is option (e).
Explanation for incorrect answer:
Option (a) 1,2,3. The epithelial tissue is not capable of contraction but covers the body surfaces. So, this is an incorrect option.
Option (b) 2,3,5. The epithelial tissue can cover the body surface and also responsible for the production of some glands. So, this is an incorrect option.
Option (c) 3,4,5. The epithelium lacks the blood vessels but can cover the free body surfaces. So, this is an incorrect option.
Option (d) 1,2,3,4. The epithelium cannot contract and also lacks blood vessels. So, this is an incorrect option.
The epithelial tissue covers the body tissues and is not vascularized. It does not contract and forms some glands. Hence, the correct answer is option (e) 2,3,4,5.
