Etymology: Quadricipital is a formal anatomical adjective meaning relating to the quadriceps, the large four-headed muscle group at the front of the thigh. It is built from Latin "quadriceps", a compound of "quattuor" ("four") and "caput" ("head"), with the English suffix "-al" added to make it an adjective. The Latin term itself was used to describe the muscle, whose four parts meet in a single tendon over the kneecap. The word belongs to the vocabulary of anatomy, which drew heavily on Latin descriptive names for body parts. English adopted the noun "quadriceps" first, and the adjective formed from it follows the same pattern as many other medical adjectives. Its meaning stays close to its literal parts: a muscle with four heads, and anything that relates to it.
