temporary set of teeth in young animals
incisor
front tooth used for cutting. Abbreviated “I”
canine
long, pointed bonelike tooth (aka cuspid, fang). Abbreviated “C”
premolar
cheek tooth found between canine teeth and molars. AKA Bicuspid because they have 2 points. Abbreviated “P”
molar
most caudally located cheek tooth used for grinding. Abbreviated “M”
dental formula
shorthand method representing the type of tooth and number of each tooth.
cheek teeth
molars and premolars
needle teeth
deciduous canines and third incisors of pigs
wolf teeth
rudimentary premolar 1 in horses
milk teeth
first set of teeth
tusks
permanent canine teeth of pigs
carnassial tooth
large, shearing cheek tooth. Upper P4 and lower M1 in dogs/ Upper P3 and lower M1 in cats.
fighting teeth
set of six teeth in llamas that include upper vestigial incisors and upper and lower canines on each side
triadan system
numbering system for teeth based on 3 digit numbers: first digit represents quadrant starting with upper right to upper left to lower left to lower right; the second and third digits represent the individual teeth starting at 01 from the rostral midline numbering up from rostral to caudal.
selennodont
animls with teeth that have crescents on their grinding surfaces (ie ruminants)
lophodont
animals with teeth that have ridged occlusal surfaces (ie equine)
bunodont
animlas with teeth that have worn, rounded surfaces (ie swine)
hypsodont
animals with continuously erupting teeth (ie cheek teeth of ruminants)
pleurodont
animals with teeth attached by one side of the inner jqw surface (ie lizards)
brachydont
animals with permanently rooted teeth (ie carnivores)
cementum
bonelike connective tissue that covers the root of the tooth
dentin
connective tissue surrounding the tooth pulp
tooth pulp
contains nerves blood vessels and loose connective tissue
apical foramen
hole at the tip of the root where nerves and blood vessels enter the tooth
periodontia
structures that support the teeth
alveoli
sockets where teeth are situated
alveolar bone
surrounds the roots of the teeth
periodontal ligament
fibrous structure that holds the tooth in the alveolus. contains collagen fibers anchored to the cementum and the alveolar bone
gingiva
mucous membrane that surrounds the teeth and forms the mouth lining
gingival sulcus
space that surrounds the tooth, located between the tooth and gingival margin
zygomatic salivary glands
found medial to the zygomatic arch
parotid salivary glands
found near the ear
sialaden/o & sial/o
combining forms for salivary glands
endodontics
branch of dentistry that involves treatment of diseases that affect the tooth pulp
exodontics
branch of dentistry that involves extraction of teeth and related procedures
oral surgery
branch of dentistry that involves surgical correction of the jaw, gums, and inside of mouth
orthodontics
branch of dentistry that involves the guidance and correction of malocclusion
periodontics
branch of dentistry that studies and treats the diseases of tooth supporting structures
pharynx
cavity in the caudal oral cavity that joins the respiratory and gastrointestinal systems. AKA throat
Ingesta
material taken in orally
ptyalism/hypersialosis
hypersalivation
deglutition
process of swallowing
esophagus
collapsible muscular tube connecting oral cavity to stomach. Located dorsal to the trachea.
celi/o
a combining form for abdomen
lapar/o
combining form for abdomen and flank
lesser omentum
fold of peritoneum that connects stomach to other visceral organs
greater omentum
fold of peritoneum that connects the stomach to the dorsal abdominal wall
monogastric
animals with one true, or glandular, stomach.
glandular stomach
one that produces secretions for digestion
ruminant vs. monogastric
ruminant have three forestomachs - rumen, reticulum, and omasum; actually outpouchings of the esophagus.
cardia
stomach entrance area located near esophagus
fundus
base of an organ - the cranial, rounded part in stomach
stomach body
aka corpus. rounded base or bottom - main part of organ
antrum
caudal part of stomach, which is the constricted part that joins the pylorus.
pylorus
narrow passage between the stomach and duodenum
pyloric sphincter
muscle ring that controls flow of material from stomach to the duodenum of small intestine
pylor/o
“gatekeeper”
rugae
folds present in the mucosa of the stomach; contain glands that produce gastric juices and mucus
cud
in ruminants, regurgitated food particles, fiber, rumen fluid and rumen organisms.
rumen
largest compartment of the ruminant stomach - serves as a fermentation vat. Divided into ventral and dorsal sac. AKA paunch.
reticulum
most cranial compartment of the ruminant stomach - aka honeycomb because it is lined with a mucous membrane that contains numerous intersecting ridges
omasum
third compartment of ruminant stomach. Has short, blunt papillae that grind food and squeeze fluid out before it enters the abomasum
abomasum
fourth compartment of ruminant stomach - glandular portion that secretes digestive enzymes. AKA true stomach.
mucosa
innermost lining of the digestive system
submucosa
thick layer surrounding mucosa containing blood vessels, lymphatic vessels and nerves
muscularis
muscular layers containing smooth muscle responsible for movements of digestive tract. Arranged in two layers
serosa
connective tissue layer covering the digestive tract. Secretes serous fluid for lubrication so abdominal organs move smoothly against each other without friction.
mesentary
fold of peritoneum that attaches the small intestine to the dorsal abdominal wall
rumination
process of bringing up food material from the stomach to the mouth for further chewing. 4 steps: regurgitation, remastication and resalivation, redeglutition.
duodenum
proximal or first portion of the small intestine, nearest the mouth.
jejunum
middle portion of the small intestine
ileum
distal or last portion of the small intestine. AKA aboral portion.
chyle
milky fluid resulting from digestion in the small intestine. Absorbed through the intestinal wall and travels via the thoracic duct and into the veins.
