Question: 168: Which of the following is not a connective tissue?
(1) Cartilage
(2) Neuroglia
(3) Blood
(4) Adipose tissue
Answer: Option (2)
Explanation:
Connective tissues include cartilage, blood, and adipose tissue,
all of which have cells embedded in an extracellular matrix and perform supportive,
transport, or storage functions.
Cartilage provides structural support and flexibility to various body parts.
Blood is a fluid connective tissue involved in transport of gases, nutrients, and wastes.
Adipose tissue stores fat and provides insulation and protection.
Neuroglia are supporting cells of nervous tissue and are not classified as connective tissue.
Therefore, neuroglia is not a connective tissue.
