[ap′ərat′əs]
Etymology: L, ad, toward, parare, to make ready
a device or a system composed of different parts that act together to perform some special function.

apparatus

Anatomy
An integrated group of structurally and functionally linked parts (including muscles, nerves, blood and lymphatic vessels, glands, stroma and so on) which act in concert to perform a particular function, as in digestion, which is performed by the alimentary apparatus (now preferentially known as the GI tract).

The use and translation of the anatomic term apparatus has proven problematic, as each information consumer views the scope (structure and function) of an apparatus in a distinct manner, and there are number of translations thereof (i.e., organs, system and tract).
 
The traditional and formally sanctioned uses of the term apparatus notwithstanding, ultimately the term system (as applied to the digestive, respiratory and urogenital apparatuses) is increasingly preferred.

Technology
A structurally and functionally integrated device used to perform a particular task.

forelimb stay apparatus
an apparatus of ligaments and tendons which prevents the forelimb from buckling while the horse is standing for long periods of time; includes mechanisms to prevent flexion of the shoulder and elbow joints, and to prevent overextension or flexion of the carpal joint.
hindlimb stay apparatus
an apparatus of ligaments and tendons which prevents the hindlimb from buckling while the horse is standing for long periods of time; includes mechanisms to lock the stifle and hock joints including the presence of a 'reciprocal apparatus', which ensures that the two joints perform in unison.
lacrimal apparatus
the structures associated with the production, flow and drainage of tears; it includes the lacrimal and accessory glands and their excretory ducts, the lacrimal canals, the lacrimal sac and the nasolacrimal duct.
reciprocal apparatus
consists of two tendinous cords in the hindlimb of the horse, the peroneus tertius and the superficial flexor, which connect the distal end of the femur to the hock, one on the cranial face of the tibia, the other on the caudal face; they ensure that the two joints always move in unison.
