When a subordinate clause is used as an adjective or an adverb, it will usually be part of a complex sentence (i.e., a sentence with an independent clause and at least one subordinate clause). The link between a subordinate clause and an independent clause will often be a subordinating conjunction or a relative pronoun.
Dermatoscopy (also known as dermoscopy or epiluminescence microscopy) is the examination of skin lesions with a dermatoscope.
Endoscopy is an examination using a tube-like device with a light on the end. A camera at the end of the tube transmits the lighted image before the tube to a TV screen so the the examiner can see the inside of the upper gastrointestinal tract as the tube advances.
