  Fibrous connective tissue - Wikipedia, the free encyclopedia
In zootomy, fibrous connective tissue (FCT) is a type of connective tissue which has relatively high tensile strength, due to a relatively high concentration of collagenous fibers.
Such tissues form ligaments and tendons; the majority of the tissue does not contain living cells, the tissue is primary composed of polysaccharides, proteins, and water.
The cells of fibrous connective tissue are mostly fibroblasts, irregular, branching cells that secrete strong fibrous proteins as an extracellular matrix.

 Dense connective tissue - Wikipedia, the free encyclopedia
Dense connective tissue, also called dense fibrous tissue, has collagen fibers as its main matrix element.
Dense connective tissue forms strong, rope-like structures such as tendons and ligaments.
Dense connective tissue also make up the lower layers of the skin (dermis), where it is arranged in sheets.

 Connective Tissue
Connective tissue (C.T.) is the second of the four primary types of tissue in the body.
These tissues are characterized by an overwhelming preponderance of the fibrous component of the tissue, with a correspondingly smaller volume of ground substance, tissue fluid and cells.
The layer underlying the epithelium is dense irregular C.T. This pink-staining tissue is composed mainly of thick interlacing collagenous fibers.

Dense connective tissue is characterised by thick bundles of connective tissue fibres, particularly collagen.
Dense connective tissue is found in two forms -regular and irregular - which are defined by the orientation of the bundles of collagen fibres.
In dense regular connective tissue, the collagen fibres are orientated in one direction with that direction being determined by the lines of tension that may be applied.

Dense irregular CT is found on the outside of many organs, in the dermis of the skin and as a distinct layer, called the submucosa, within various organs.
Dense regular CT is found in tendons (which connect muscles to bones), ligaments (which connect bones to bones, some also contain large amounts of elastic fibres and are called elastic ligaments), and aponeuroses (broad flattened tendons whose fibres are arranged in multiple layers, within each layer the fibres are regularly arranged).

But you may already be able to imagine that "fibrous" joints are held together by fibrous connective tissue, "cartilaginous" joints have cartilage within them, and "synovial" joints are something altogether different.
You learned back in the connective tissue chapter that when dense connective tissue is used to hold bones together, we call that tissue a ligament.
Because this capsule is composed of dense connective tissue, and dense connective tissue (regular) can form ligaments and tendons, you'll see that this capsule typically serves as both protection for what's inside and as ligaments or tendons for the joint.
