external capsule the layer of white fibers between the putamen and claustrum.
fibrous renal capsule the connective tissue investment of the kidney, which continues through the hilus to line the renal sinus.
Glisson's capsule a sheath of connective tissue accompanying the hepatic ducts and vessels through the hepatic portal. In hepatitis it may become stretched, which is a common cause of pain.
glomerular capsule Bowman's capsule.
capsule of heart pericardium.
internal capsule the fanlike mass of white fibers separating the lentiform nucleus laterally from the head of the caudate nucleus, the dorsal thalamus, and the tail of the caudate nucleus medially. The internal capsule carries both afferent and efferent fibers of the cerebral cortex.
joint capsule articular capsule.
capsule of lens the elastic sac enclosing the lens of the eye.
malpighian capsule Bowman's capsule.
capsule of pancreas a thin sheath of areolar tissue that invests the pancreas (but does not form a definite capsule), the septa of which extend into the gland and divide it into lobules.

They can manifest as a cluster of accessory fascicles arising from coracoids process, pectoralis minor tendon, proximal head of humerus or articular capsule of humerus [2].
The articular capsule was already well defined in the fetuses with 16 weeks of intrauterine life.
In our work we could observe that the insertion of the lateral pterygoid muscle through its superior head occurs in the articular disc and in the articular capsule, in all studied ages.
We also agree with Wierusz &Wozniak (2004) when relate that in fetuses of 9 and 10 weeks, the articular disc is connected with the articular capsule and lateral pterygoid muscle.
Regarding the comments above, the following conclusions were obtained: the fibers and the thickness of the articular disc, as well as, the articular capsule and the condylar process, suffer modifications according to age; the superior head of the lateral pterygoid muscle is inserted in the disc and in the articular capsule, in all the studied ages; the maturation of the articular tissues, in special the articular disc, as well as, the associated muscles suggest that the TMJ was capable of doing mandibular movements from the 24th week of intrauterine life.
These muscle had its origin in the anterior surface of the distal third of femur, as it was demonstrated by some authors (Ahmad; Gray; Kendall; Kincaid et al.; Moore & Dalley) and its muscular bundles was inserted in the articular capsule over the surface of the suprapatellar bursa (Rouviere; Ahmad; Kendall; Salgado; Moore & Dalley; Didio, 2002).
The oblique ligament represents a reinforcement of the articular capsule and therefore has not been named by the International Committee of Nomenclatura Anatomica Veterinaria (NAV,1994).
Evans defined the oblique ligament as a small bundle of fibers in the articular capsule, which arises from the dorsal margin of the supratrochlear foramen and crosses the elbow joint distally and medially to the tendons of the biceps brachii muscle and brachial muscle, and at the level of these tendons the oblique ligament divides into two parts: cranial and caudal portions.
Maximum length between the points of origin and insertion of the caudal portion of the medial collateral ligament (measured from the medial epicondyle to the caudolateral surface of the proximal portion of the radius) and cranial portion of the oblique ligament (measured from the articular capsule in the region of the lateral condyle of the humerus to the proximal and medial margin of the radius).
The cranial portion is short and fuses with the articular capsule and with the caudal or short portion of the oblique ligament.
The oblique ligament is a thin whitish structure presenting as a cranial reinforcement of the articular capsule (Fig.
