Chapter 5 Flashcards
Cheeks form the walls of the oral cavity
bucc/o
Lips surround the opening of the cavity
(cheil/o or labi/o)
The hard palate forms the anterior portion of the roof of the mouth
(plata/o)
The soft palate is posterior to the hard palate.
(plata/o)
Ridges in the mucous membrane covering the anterior portion of the hard palate (the front part)
Rugae
Hangs from the soft palate (aids the production of sounds and speech)
Uvula
(uvul/o)
Uvula
It moves food around during mastication (chewing)
and deglutition (swallowing)
tongue
gloss/o
tongue
Taste buds; are sensitive to chemical nature of foods and allow discrimination of different tastes as food moves across the tongue.
Papillae
Lie on both sides of the oropharynx;
They protect the body from invasion of microorganisms and produce lymphocytes, disease-fighting WBC’s
Tonsils
tonsill/o)
Tonsils
Fleshy tissue surrounding the sockets of the teeth
Gums
gingiv/o
Gums
dent/i
teeth
(odont/o)
teeth
Part above the gum line
crown
within the bony tooth socket
root
Protects the tooth (hardest tissue in the human body)
-translucent
Enamel
the main substance of the tooth, lies beneath the enamel and
extends throughout the crown
Dentin
covers, protects, and supports the dentin in the root
Cementum
surrounds the cementum and holds the tooth in place in the tooth socket
Periodontal membrane
Lies underneath the dentin
Pulp (root canal)
salivary gland near the ear
parotid
smallest salivary gland (under mouth)
sublingual gland
salivary gland under the lower jaw
submandibular gland
Passageway for air traveling in the nose to the windpipe (trachea) and for food traveling from the oral cavity to the esophagus
throat (pharynx)
When swallowing (deglutition), a flap of tissue covers the food so that it cannot fall into the trachea (windpipe)
Epiglottis
the involuntary, progressive, rhythmic contraction of muscles in the wall of the esophagus (and other gastrointestinal organs
Peristalsis
control what comes in and out of the stomach (controls the opening and exit)–> It helps food from not flowing in the opposite direction (regurgitating)
Sphincters
relaxes and contracts to let food enter from the esophagus (ENTER) (LES)
Lower esophageal sphincter
increase surface area for digestion and contain glands that produce pepsin enzyme
Rugae
allows food to exit the stomach and enter the small intestine
Pyloric sphincter
receives food from the stomach and bile from the liver and gallbladder and pancreatic juices from the pancreas (bile and juices help further digest food
Duodenum
Middle part of small intestines
Jejunum
attaches to the first part of the large intestine
ileum
What lines the walls of the small intestine?
Villi
ring of muscle at the end of the stomach
pyloric sphincter
chemical that speeds up reactions and helps digest
foods
enzyme
First part of the large intestine connecting to the ileum
Cecum
What hangs from the cecum
appendix
extends from the cecum (when it turns left to go to the transverse colon –> underlines the liver)
Ascending colon
Horizontal colon
transverse colon
attached to the transverse colon–>going all the way down to the sigmoid colon
descending colon
Shaped like an S; begins at the distal end of the descending colon and leads into the rectum
sigmoid colon
the process of the passage of feces from the body through the anus
defecation
