What tissue type has collagen fibers running in parallel lines?
Dense Connective Tissue: tendons, ligaments, aponeuroses, capsules of organs, and dermis. There are two divisions: 1) regular dense connective tissue is characterized by collagen fibers held together in parallel bundles with fibroblasts rows sandwiched in between.
Which tissue contains large amounts of densely packed collagen fibers that run parallel to each other quizlet?
Contains elastic fibers and is found in the lungs. This tissue allows the lungs to inflate during inhalation and return to their original shape after exhaling. Packed with parallel bundles of collagen fibers and found in tendons.
Which tissue contains large amounts of densely packed collagen fibers that run parallel to each other?
Dense regular connective tissue
Dense regular connective tissue is mainly made up of type I collagen fibers. It is found in areas of the body where large amounts of tensile strength are required, like in ligaments, tendons and aponeurosis. The collagen fibers are densely packed together and arranged in parallel to each other.
What fibers does adipose tissue have?
It consists of a fine network of reticular fibers (type III collagen), whose function is to hold the cells in place. Adipose tissue is richly supplied with blood vessels and unmyelinated nerve fibers.
Which tissue includes nonliving extracellular matrix?
The connective tissues are important in providing protection and support to the body. They are composed largely of the nonliving extracellular matrix.
Which type of connective tissue is composed of packed parallel bundles of collagen fibers and found in tendons?
Dense irregular tissue is packed with parallel bundles of collagen fibers and found in tendons. This tissue resists pulling forces applied by muscles. Fibrocartilage has a firm, gelatinous ground substance containing collagen fibers.
What connective tissue consists of large round densely packed cells?

What is the difference between dense regular and dense irregular?
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.
Do all tissues have an extracellular matrix?
The extracellular matrix (ECM) is the non-cellular component present within all tissues and organs, and provides not only essential physical scaffolding for the cellular constituents but also initiates crucial biochemical and biomechanical cues that are required for tissue morphogenesis, differentiation and homeostasis …
How does extracellular matrix relate to connective tissue?
The extracellular matrix (ECM) is responsible for the physical maintenance1 of all cells. The ECM can be defined as the non-cellular component of tissues, which has been likened to ‘glue’ that binds cells together in connective tissues, where it is a major constituent of the tissue.
How is adipose tissue different from other connective tissues?
Adipose tissue, or fat tissue, is considered a connective tissue even though it does not have fibroblasts or a real matrix, and has only a few fibers. Adipose tissue is composed of cells called adipocytes that collect and store fat in the form of triglycerides for energy metabolism.
What type of cells produce reticular fibers in connective tissue?
In specialized connective tissue, different fixed cells like osteocytes (bone) and chondrocytes (cartilage) are found in large quantities. Reticular cells produce reticular fibers but play the role of fibrocytes in areas of tissue that contain reticular fibers.
What are collagen fibers?
Collagen fibers are tough, thick fibrous proteins found in dense connective tissues. It has many types but in dense connective tissue mainly type I collagen is present. Three stranded collagen molecules are packed together to form collagen fibrils and their alignment yield characteristic ultrastructural striations.
Why do surface cells have the ability to slide over one another?
The surface cells have the ability to slide over one another, increasing the internal volume of the organ (e.g., bladder) as it fills and maintaining an intact lining whether stretched or contracted. 9. How do the endocrine and exocrine glands differ in structure and function?
