Oblique fibers | Main support of the tooth as they are most numerous and resist forces |
What fiber prevents tipping and resists twisting? | Apical fibers |
Interdental fibers are found where and secures what? | In between teeth and secure position of adjacent tooth |
What are the three types of mucosa in the gingival unit? | Lining mucosa, masticatory mucosa and specialized mucosa |
What mucosa lines the inside of the cheeks, lips, split palate and ventral surface of the tongue? | Lining mucosa |
The masticatory mucosa covers what and is designed to do what? | Attached gingiva, hard pallets and dorsum of the tongue | -designed to withstand forces of chewing |
The specialized mucosa is responsible for what? | Sensations of taste and covering the dorsal of the tongue |
Gingiva is also known as the what? | Gums |
A healthy gingiva looks how? | Stippled and similar to the surface of an orange |
The unattached gingiva is also known as the what? | Marginal or free gingiva |
Space between tooth and gum | Sulcus |
Epithelial attachment | Tissue at the base of sulcus where the gingiva attaches to the tooth |
The extension of the free gingiva that fills the interproximal embrasure between the two teeth is known as | Interdental gingiva |
A shallow groove that runs parallel to the margin of the unattached gingiva and marks the beginning of attached gingiva | Gingival groove |
The oral cavity consists of two areas which are | Vestibule and the oral cavity proper |
Vestibule is the space between what? | Teeth and inner mucosal lining of the lips and cheeks |
The space on the tongue side within the upper and lower dental arches is the what? | Oral cavity proper |
Mucobuccal fold | The base of each vestibule where the bucks mucosa meets the alveolar mucosa |
Fordyce’s spots are what? | Misplaced sebaceous glands |
The white ridge of raised tissue extending horizontally at the level where the max and mand teeth come together is known as | Linea alba |
A slightly raised line extending from the back of the incisive papilla and down the middle of the hard palate | Palatine raphe |
The palatine Rugae is what? | The ridges that run horizontally across the hard palate behind the incisive papilla |
The opening between the two pillars and contains the palatine tonsils is known as what? | Isthmus or fauces |
What is the ala? | Winglike tip on the outer side of each nostril |
Philtrum | Vertical groove on the midline of the upper lip |
Tragus | Cartilage projection anterior to the external opening of the ear |
Canthus | Fold tissue at the corner of the eyelid |
The line that marks a colour change from your face to your lips is known as | Vermillion border |
