What is the structure and function of connective tissue?

Tissue that supports, protects, and gives structure to other tissues and organs in the body. Connective tissue also stores fat, helps move nutrients and other substances between tissues and organs, and helps repair damaged tissue. Connective tissue is made up of cells, fibers, and a gel-like substance.

What is the structure of connective tissue cells?

Structural elements of connective tissue: Connective tissues consist of three parts: cells suspended in a ground substance or matrix; and most have fibers running through it. Ground substance is a clear, colorless, viscous fluid that fills the space between the cells and fibers.

What is the structure and function of loose connective tissue?

Loose connective tissue is found between many organs where it acts both to absorb shock and bind tissues together. It allows water, salts, and various nutrients to diffuse through to adjacent or imbedded cells and tissues. Adipose tissue consists mostly of fat storage cells, with little extracellular matrix ((Figure)).

What are the 4 types of connective tissue?

There are four classes of connective tissues: BLOOD, BONES, CARTILAGE and CONNECTIVE TISSUE PROPER.

What are the 7 types of connective tissue?

7 Types of Connective Tissue

• Cartilage. Cartilage is a type of supporting connective tissue.
• Bone. Bone is another type of supporting connective tissue.
• Adipose. Adipose is another type of supporting connective tissue that provides cushions and stores excess energy and fat.
• Blood.
• Hemapoetic/Lymphatic.
• Elastic.
• Fibrous.

What are 3 general characteristics of connective tissue?

Connective tissues come in a vast variety of forms, yet they typically have in common three characteristic components: cells, large amounts of amorphous ground substance, and protein fibers.

What are 3 types of connective tissue?

The three types of connective tissue fibers are:

• Collagen fibers – most are type I collagen (most abundant protein in the body)
• Elastic fibers – contain elastin and fibrillin.
• Reticular fibers – contain type III collagen.

What are examples of loose connective tissue?

Examples of loose connective tissue include areolar tissue and reticular connective tissue.

What are the 7 major types of connective tissue?

What are the 10 types of connective tissue?

The following points highlight the ten main varieties of connective tissues of human body. They are: 1. Areolar Tissue 2. Adipose Tissue 3….Reticulo-Endothelial Tissue.

• Areolar Tissue:
• Adipose Tissue (Fig.
• White Fibrous Tissue (Fig.
• Yellow Elastic Tissue (Fig.
• Reticular Tissue (Fig.
• Blood and Haemopoietic Tissue:

What parts of the body are classified as connective tissue?

The connective tissues include several types of fibrous tissue that vary only in their density and cellularity, as well as the more specialized and recognizable variants—bone, ligaments, tendons, cartilage, and adipose (fat) tissue.

What is the most common loose connective tissue?

areolar tissue
Loose CT (or areolar tissue) is the most widespread CT of the body. It is characterized by an abundance of ground substance, plus thin and relatively few fibres and cells (Fig. 1.7). The main cellular elements are fibroblasts and a smaller amount of adipocytes.

How is the structure of connective tissue related to its function?

The amount and structure of each component correlates with the function of the tissue, from the rigid ground substance in bones supporting the body to the inclusion of specialized cells; for example, a phagocytic cell that engulfs pathogens and also rids tissue of cellular debris.

How are specialized cells in connective tissue protect the body?

Specialized cells in connective tissue defend the body from microorganisms that enter the body. Transport of fluid, nutrients, waste, and chemical messengers is ensured by specialized fluid connective tissues, such as blood and lymph. Adipose cells store surplus energy in the form of fat and contribute to the thermal insulation of the body.

How are cells distributed in connective tissue cartilage?

Loose connective tissue has abundant cells among few or loosely arranged fibers and a sparse to abundant gelatinous ground substance. Dense connective tissue has few cells among a dense network of fibers with little ground substance. Cartilage has cells distributed among fibers in a firm gellike ground substance.

What kind of cells are found in loose connective tissue?

Cells that have matured, or differentiated (whose names often end in cyte), function mostly to maintain the matrix: Fibroblasts are common in both loose and dense connective tissues. Adipocytes, cells that contain molecules of fat, occur in loose connective tissue, as does adipose tissue.
