TRANSVERSE PROCESS
The lateral process of the vertebrae, which stems from the junction between the lamina and the pedicle.

TRANSVERSUS ABDOMINUS MUSCLE
Muscle responsible for the compression of the abdominal viscera. It originates at the cartilages of the six lower ribs, thoracolumbar fascia, iliac crest, and inguinal ligament, and inserts into the linea alba and conjoined tendon to pubis.

TRIGONE
(Lateral ventricle)The triangular area between the temporal and occipital horns at the junction with the body of the lateral ventricle.

TRUE VOCAL CORD
The mucous membrane surrounding the vocalis muscle in the larynx, forming the inferior ventricular boundary. Air moving over this fold produces the vibrations of speech.

TUBERCLE OF RIB
A small eminence on the posterior side, where the head and body of a rib join.

UNICATE PROCESS
Literally a "hook". For the ethmoid bone, a plate of bone down and to the back from the anterior portion of the ethmoid labyrinth.

UNICATE PROCESS OF PANCREAS
The left and caudal portion of the head of the pancreas that "hooks" around.

URETER
A fibromuscular tube that transport urine from the collecting pelvis of the kidney to the base of the bladder, via a "stripping-wave" type of peristalsis.

URETHRA
A membraneous canal used in the transportion of urine from the bladder to the outside.

UTERINE CAVITY
The lumen within the uterus that is connected laterally to the uterine (fallopian) tubes and posteriorly/inferiorly with the cervix and vagina.

UTERUS
A hollow muscular organ in which the fertilized ovum is embedded.

UVULA
A small fleshy mass located on the soft palate above the root of the tongue. (The dangly thing hanging in the back of your throat.) "It'll behoove ya' to take care of your uvula".

VAGINA
Part of the female genitalia, the canal extending from the vulva to the cervix uteri.

VALLECULA
A furrow located on the lateral and median glossoepiglottic folds.

VALVE
A membraneous structure within a tube that prevents the return flow of the contents passing through it. The veins of the extremities have valves.

VENOGRAM
A radiograph or other image of veins.

VENTRICLE
A fluid-filled cavity. The heart has a right and left ventricle filled with blood. The brain has four ventricles: the two lateral, and the midline third and fourth - filled with cerebrospinal fluid.

VERTEBRAL ARTERY
Originating at the subclavian artery, passing vertically through the transverse foramina of the vertebrae, and branching into the spinal and muscular rami, anterior spinal artery, and posterior inferior cerebellar artery, before joining with the opposite side to form the basilar artery.

VERTEBRAL BODY
Actually, only the main round, anterior portion of the vertebrae. The part from which the other processes extend. However, often used as a nickname for the entire vertebra.

VESTIBULE
(of Ear)The oval cavity within the bony laryrinth that is a confluence for the endolymph.

VITREOUS BODY
The inner part of the eyeball located between the lens and retina that is made up of a transparent gel (actually a living tissue).

XIPHOID PROCESS
The cartilagenous process, with a bony core, connected to the inferior end of the of the sternum. The inferior tip of the sternum. (from the Greek "xiphias" - literally "sword")

ZYGOMATIC ARCH
The horizontal arch of the cheek bone, formed by the temporal process of the zygomatic bone and the zygomatic process of the temporal bone that attaches the masseter muscle.
