Study Set Content:
Adipose tissue function
- protects parts of the body and acts as a thermal insulator.
forms the framework of lymphatic tissue, such as in the spleen and lymph nodes, as well as in bone marrow and the liver
Reticular tissue
- has a relatively large number of protein fibers that form thick bundles and fill nearly all of the extracellular space.
Dense connective tissue
There are two major subcategories of dense connective tissue:
- collageneous and elastic.
- has an extracellular matrix consisting mostly of collagen fibers.
Dense collagenous connective tissue
Dense collagenous connective tissue having the collagen fibers oriented in the same direction is termed
dense regular
Examples of dense regular are
tendons and ligaments
Dense collagenous connective tissue having the collagen fibers oriented in the multiple directions is termed
dense irregular
Examples of dense irregular are in the
- dermis of the skin and in organ capsules.
- has abundant elastic fibers among its collagen fibers.
Dense elastic connective tissue
Examples include the dense elastic connective tissue in the
vocal chords
- A genetic condition results from, in part the inability to properly maintain and form elastic fibers.
Marfan syndrome
is composed of chondrocytes, located in spaced called lacunae within an extensive matrix.
Cartilage
- gives cartilage flexibility and strength.
Collagen
- is the most abundant type of cartilage and has many functions, such as covering the ends of bones, where they form joints.
Hyaline cartilage
- has more collagen than does hyaline cartilage and is able to withstand compression and resist tearing or pulling.
Fibrocartilage
- s found in the disks between the vertebrae (bones of the back) and in some joints, such as the knee and temporomandibular (jaw) joints.
Fibrocartilage
- contains elastic fibers in addition to collagen and proteoglycans.
Elastic cartilage
The elastic fibers appear as coiled fibers among bundles of
collagen fibers
The external ear, epiglottis, and auditory tube contain
elastic cartilage
