The duodenal submucosa is especially prosperous and mainly composed of dense connective tissue
containing few Brunner's glands.
The tendon is surrounded by a paratenon which is a dense connective tissue
structure that appears as echogenic borders surrounding the tendon.13,14 AT is a relatively large superficial structure, easily imaged by ultrasound which can be helpful in distinguishing between Achilles tendinitis, paratenonitis, and retrocalcaneal bursitis.
IO = intromittent organ; DCT = dense connective tissue
; LCT = loose connective tissue; FR = fin ray.
As reported for the pirarucu oesophagus, the occurrence of dense connective tissue
in the rectal submucosa is most likely involved in protection against distension (Reifel & Travill, 1979).
There are multiple abnormal secondary follicles that radiate from the primary cystic structure, and the entire apparatus is surrounded by a well-circumscribed dense connective tissue
. Immuno-histochemical studies have revealed that trichofolliculoma is characterized by activated, aberrant cytokeratin-15 (CK15)-positive follicle stem cells that show outer root sheath differentiation while attempting to make hair.
The membranous part of the interventricular septum is devoid of cardiac muscle; it consists of dense connective tissue
that contains a short length of the unbranched A-V bundle of the conducting system of the heart.
Twelve terms encompassing structures often called fascia have been proposed : dense connective tissue
, areolar connective tissue, deep fascia, superficial fascia, interosseous membranes, intermuscular septae, epimysium, perimysium, endomysium, periosteum, neurovascular tract, and intra- and extramuscular aponeuroses.
(18,27,57) Based on certain common characteristics, including the fiber arrangement, connective tissue proper is classified by the Terminologia Histologica as loose connective tissue and dense connective tissue
. (24) The dense connective tissue
is sub-categorized as: i) unidirectional parallel ordered dense connective tissue
, ii) multidirectional parallel ordered dense connective tissue
, iii) woven connective tissue, iv) irregular fusocellular connective tissue.
Fascia is dense connective tissue
that is high in ECM and is richly innervated.
The muscle origins on the interosseous ligament were verified histologically, where striated muscle originated directly from the dense connective tissue
of the interosseous ligament.
The ACL consists of two bundles of dense connective tissue
, the anteromedial and the posterolateral bundles.
