Dense connective tissue, also called dense fibrous tissue, is a type of connective tissue with fibers as its main matrix element. The fibers are mainly composed of type I collagen. Crowded between the collagen fibers are rows of fibroblasts, fiber-forming cells, that generate the fibers.
What are the characteristics of dense regular connective tissue?
Functions. Dense regular connective tissue has great tensile strength that resists pulling forces especially well in one direction. DRCT has a very poor blood supply, which is why damaged tendons and ligaments are slow to heal.
Does dense regular connective tissue have nuclei?
in regular dense connective tissue (tendons) the collagen bundles are more-or-less parallel and so are the rows of fibrocyte nuclei. Remember : In fibrous connective tissue, especially dense, nuclei of fibrocytes are thin and flat! … The collagen bundles are thick and parallel.
What is dense regular connective tissue class 11?
Hint: Dense regular connective tissue provides connection between different tissues in the human body. They have great tensile strength. Complete Answer: – Dense regular connective tissues are found between different tissues in the human body. They act as a connecting link between the tissues.
What are the 4 main types of connective tissues?
Connective Tissue
- Loose Connective Tissue.
- Dense Connective Tissue.
- Cartilage.
- Bone.
- Blood.
What are examples of dense connective tissue?
In particular, tendons and ligaments are examples of dense regular connective tissue. Tendons connect muscles to bones whereas ligaments connect a bone to another bone. Other examples include the perichondrium around the tracheal cartilage and the tunica albuginea around the testis.
What are the 3 main types of connective tissue?
There are three main groups of connective tissues: loose connective tissue, dense connective tissue, and specialized connective tissue.
Where is irregular dense connective tissue found?
The dense irregular connective tissues are found in the lower layers of the skin (dermis) and in the protective white layer of the eyeball. See also: connective tissue.
Where can we find dense connective tissue?
Dense connective tissue is often seen as the capsules enclosing organs and, in particular, tubular structures, but is most strikingly characterized in its appearance as tendons and ligaments.
What is the difference between regular and irregular dense connective tissue?
In dense regular connective tissue, collagen fibers are arranged parallel to each other in the form of a bundle that is arranged in a specific orientation. In dense irregular connective tissue, fibers are not arranged parallel, and the bundles are not arranged in a specific orientation.
What’s the difference between loose and dense connective tissue?
The main difference between loose connective tissue and dense connective tissue is that loose connective tissue consists of protein fibers packed with spaces whereas dense connective tissue consists of tightly packed protein fibers. The three types of loose connective tissue are areolar, adipose, and reticular tissues.
What is dense connective tissue made of?
The dense connective tissue is a type of connective tissue proper that consists predominantly of fibers, especially type I collagen. It also has fibroblasts that generate the fibers. Compared with the loose connective tissue, the dense connective tissue has less cellular variation and ground substance.
Which of the following is NOT example of dense connective tissue?
Which of the following is not an example of connective tissue? Explanation: Skin is composed of epithelial cells, and is therefore not an example of connective tissue. The major types of connective tissue include bone, adipose, blood, and cartilage.
Which of the following is made up of dense irregular connective tissue?
The reticular layer of the dermis is made up of dense irregular connective tissue.
What are the 5 main types of connective tissue?
Connective tissue proper includes: loose connective tissue (also called areolar) and dense (irregular) connective tissue. Specialized connective tissue types include: dense regular connective tissue, cartilage, bone, adipose tissue, blood, and hematopoietic tissue.
What is the most common connective tissue disorder?
Rheumatoid Arthritis (RA): Rheumatoid arthritis is one of the most common connective tissue diseases and can be inherited. RA is an autoimmune disease, meaning the immune system attacks its own body. In this systemic disorder, immune cells attack and inflame the membrane around joints.

What are connective tissues two examples?
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 are the two main categories of connective tissues?
Connective tissue has three main components: cells, fibers, and ground substance. Together the ground substance and fibers make up the extracellular matrix. Connective tissue is classified into two subtypes: soft and specialized connective tissue.
Which is not a type of connective tissue proper?
Explanation: Skin is composed of epithelial cells, and is therefore not an example of connective tissue. The major types of connective tissue include bone, adipose, blood, and cartilage.
Why is blood called a connective tissue?
Blood is considered a connective tissue because it has a matrix. The living cell types are red blood cells, also called erythrocytes, and white blood cells, also called leukocytes. … Blood Tissue: Blood is a connective tissue that has a fluid matrix, called plasma, and no fibers.
Is blood dense connective tissue?
Dense regular connective tissue, found in structures such as tendons and ligaments, is characterized by collagen fibers arranged in an orderly parallel fashion, giving it tensile strength in one direction. … Blood and lymph are fluid connective tissues.
