___ tissues are sheetlike with one free surface.
- a. Epithelial
- b. Muscle
- c. Nervous
- d. Connective
Introduction: The body tissues contain a group of specialized cells that can organize as organs. They have the same structure that can perform a particular function. In a human body, there involves 4 main types of tissues—muscle tissue, connective tissue, epithelial tissue, and nervous tissue.
Answer to Problem 1SQ
Correct answer: Epithelial tissues are sheetlike with one free surface.
Hence, the correct answer is option a.
Explanation of Solution
Reason for correct answer:
The epithelial tissue is a type of tissue that is made up of epithelial cells, and it is a sheet-like cell layer having no extracellular matrix between them. They help to cover the surface of the body and line its internal cavities and tubes. These tissues have one free apical surface. The apical surface refers to the epithelial tissue facing outside environment and the basal surface refers to the epithelial tissue facing the basement membrane. The epithelial cells can be classified into three types based upon their cell shape—cuboidal, squamous, and columnar epithelia. The major functions of the epithelial cells are for secretion, absorption, protection, and sensing.
Option a. is given as “epithelial”.
The epithelial tissue is a type of tissue that is made up of epithelial cells, and it is a sheet-like cell layer having no extracellular matrix between them. These tissues have one free apical surface.
Hence, the correct answer is option a.
Reasons for incorrect answer:
Option b. is given as “muscle”.
Muscle tissues are long and fibrous excitable cells that help for the muscle contraction of the body. These tissues are not sheetlike with one free surface.
Hence, option b. is incorrect.
Option c. is given as “nervous”.
Nervous tissues are present in the nervous system that helps to transmit the signals from the nerves to the brain and spinal cord. These tissues are not sheetlike with one free surface.
Hence, option c. is incorrect.
Option d. is given as “connective”.
Connective tissues help to connect the tissues among one another. These tissues are not sheetlike with one free surface.
Hence, option d. is incorrect.
Hence, the options b., c., and d. are incorrect.
