              • Ban (Old English) - Bone, tusk
            • Triangular shaped bone that is the third most commonly fractured wrist bone
            • Derived from Latin triquetrus, meaning threecornered

            • Mnemonics
              So Long To Pinky, Here Comes The Thumb
              The bones of the wrist
              Scaphoid, Lunate, Triqutrim, Pisiform, Hamate, Capitate, Trapezoid, Trapezium
              Tunica vaginalis

              Involved in inflammatory response which causes "swelling."

            • The remnant of the processus vaginalis, an outpouching of the peritoneum. Provides a serous covering of the testicles. A hydrocele of the testicle can develop if the processus vaginalis remains patent.
            • Ulna

              This bone is the major contributor to the "elbow"

              • Ulna (Latin) - Elbow

              • Un (Old English) - Prefix of negation
              • Stabilis (Latin) - Firm, steadfast, fixed

            • Velocity

              Unit of measurement to determine "speed or swiftness."

            • Velocity is applicable to medicine by virtue of drug metabolism, transportation of molecules into cells, and by enzymatic reactions in the body
            • V= dx/dt where V is velocity, dx is change in distance, and dt is change in time.
            • Vestibular glands

              Glands found at "entrance" of vagi.

            • These glands secrete mucus to lubricate the vagi during sexual arousal. Infection and inflammation of these glands leads to pathognomonic enlargement just lateral to the vagi, known as a Bartholin cyst
            • Also known as the Bartholin's Glands, med after the Danish atomist Caspar Bartholin who discovered them
            • Sometimes mistakenly thought to have been described by his grandfather with the same me.
            • Vestibular nerve

              Transmit equilibrium information from the "entrance" of ear cal.

              • Vestibulum (Latin) - Forecourt, entrance
              • Nervus (Latin) - Sinew, tendon; cord, bowstring
            • Division of cranial nerve VIII that arises in the vestibular ganglion at the entrance of the ear canal and provides information about equilibrium
            • Dermatome

              Referring to two separate items, the first of which is a surgical "instrument used for cutting" thin slices of "skin". In general medicine it refers to the various "skin" areas and their innervations.

              • Derma (Greek) - Skin
              • Tome (Greek) - Instrument used for cutting
            • Dermatomes refer commonly to areas of the skin innervated by single spinal nerves.
            • The following dermatomes are high yield and commonly associated with their anatomic landmarks:
            • T4- The level of the nipple
            • T10- The level of the umbilicus
            • Dermatome also refers to a surgical instrument commonly used for the thin slicing of skin to be used for skin grafts.
            • These grafts are commonly used in Stage III burn victims
            • Coloboma

              A "defect" or hole, usually in one of the structures of the eye

            • - Coloboma of the eye most commonly affects the iris, creating an often larger area of black (the pupil) - Can also affect the retina, choroid, or optic disc - Coloboma of the eye is the "C" in CHARGE Syndrome
