Question

Collagenous connective tissue layer holding the muscle bundles together is
A. Pleura
B. Pericardium
C. Sarcolemma
D. Fascia
E. Sarcoplasm

Answer 1

The most abundant and widely distributed primary tissues located as a matrix beneath the epidermal layer is called the connective tissue. It is mesodermal in origin and connects tissues and organs of the body.

Complete answer:
The tissue that protects and provides a structural framework for the tissues and organs in our body is called the connective tissue. It has three main components- cells, fibers, and a gel-like or ground like substance. The connective tissue fibers are of three types-
Collagen Fibre- Most abundant and made up of Collagen I. Provide tensile strength and rigidity to the tissues.

1)Elastic Fibre- Made up of elastin and fibrillin, and provides elasticity.
2)Reticular Fibre- Made up of collagen III, and provides support.

The cells in the connective tissue- are surrounded by an extracellular matrix. Based on the structure of the extracellular matrix and cells present, connective tissue can be classified as
Connective tissue proper- They are found throughout the body. They are further subdivided into two categories- Loose connective tissue and Dense connective tissue.
Special connective tissue- They have specific cells and are present in specific places- and have specific functions. They consist of reticular connective tissue, adipose tissue, cartilage, bone, blood, and embryonic connective tissue.

Let us analyze the options to find the correct answer.

Option A: Pleura are the two thin layer tissues that protect the lungs. Therefore, this is the incorrect option.
Option B: Pericardium is a thick connective tissue that surrounds the heart and holds its position in the chest cavity. Therefore, this is the incorrect option.
Option C: The cell membrane of the striated muscle fibers is called the Sarcolemma. Therefore, this is the incorrect option.
Option D: Fascia is a connective tissue layer made up of collagen. It is responsible for holding organs, blood vessels, muscles, bones, and nerve fibers in their places and provide support to them. It surrounds muscles, groups of muscles, blood vessels, and nerves. Therefore, this is the correct option.
Option E: The cytoplasm of the muscle fiber is called Sarcoplasm. Therefore, this is the incorrect option.
Hence, the correct answer is option (D)

Note: Fascia is a special type of connective tissue made up of bands and sheets and present almost everywhere in our body. It provides structural support to the skeleton and various tissues in our body. It has both loose and dense fibrous connective tissue.
