A
sides parallel; hence, trapezius muscle, the diamond-shape of
B
both trapezii muscles together.

C parallel sides, resembling a trapezium.
tri- three (try)
D
Triad when pertaining to the liver, a triad is a combination of 3
E

They include branches of the hepatic portal vein, hepatic artery, and
F
bile duct. When pertaining to skeletal muscle, a triad refers to a T
G
tubule and two cisternae of the sarcoplasmic reticulum.
triad: from Lt. tres = 3.
H
triceps: Lt. tres = 3, and caput = head; hence a 3-headed
I
muscle.
trigeminal: Lt. trigeminus = triplets; hence, cranial nerve V, with 3
J large divisions.
trigone: Lt. trigonum = a triangle.
K
triquetral: Lt. triquetrus = 3-cornered.
L
triticea: Lt. triticum = a grain of wheat; hence, the tiny cartilage in

P
trop- turn change
troph- nutrition
Q truncus: Lt. = trunk (of a tree).
tube: origin unknown
R
tubule: little tube
S
tuber: Lt. tuber = a swelling or lump. (see protuberance)
Tubercle (TEW-ber-cl) a small process or bump generally on a bone.
T
tubercle: Lt. diminutive of tuber, a small prominence, usually bony
U
(smaller than a tuberosity).
tuberculum: Lt. diminutive of tuber, a small prominence, usually
V
bony.
W
tuberosity: Lt. tuber = a swelling or lump, usually large and rough
(larger than a tubercle).
X tunica: Lt. = shirt; hence a covering.
Tunica externa (TEW-nih-kah eks-TEHRN-ah) the outermost layer of
Y
a tubular BV wall. (also = the tunica adventitia and the serosa, it is
Z
composed of CT and in larger vessels smaller BVs the vasa vasorium)
