Oral Anatomy MCQs have been collected from the past papers which were taken from the different Army Selection & recruitment Centers regarding medical tests.

Those who are expert and have vast knowledge about Tumer, Nodes and Metastasized with their MBBS degrees recognized by PM&DC, they need no worry about job in Pakistan Army as an M-Cadet. Such multiple choice questions are very important for passing medical initial tests of Pak Army.

Such candidate who fulfil the basic criteria to Join Pak Army through Short Service Regular Commission and want to register themselves for Captain or Major then the given past experience of past questions are very helpful for them.

Visit this page in detail for tests pattern and syllabus regarding medical tests with all pre-requisites for becoming medical officers in Pak Defence Forces. 

Females can also apply those who have MBBS or BDS degree from any Army Medical Colleges with pre medical FSc or equivalent.

Following tests of Oral Anatomy MCQs are given to clear academic tests which have been taken in the initial tests of Army , Navy or Pakistan Air Force Medical Officer. These questions are very useful for all M-Cadet tests.

Pulp, dentin, enamel, and cementum are the four forms of tissue that make up a human tooth. The pulp, which makes up the tooth’s inside and nourishes it, is made up of connective tissue, nerves, and blood vessels.

The lips, vestibule, mouth cavity, gums, teeth, hard and soft palate, tongue, and salivary glands are all components of the mouth.

(OR-ul KA-vih-tee) The mouth is referred to. The lips, the lining of the cheeks and lips, the upper and lower gums, the floor of the mouth beneath the tongue, the bony roof of the mouth, and the little space behind the wisdom teeth are all included in this region.

The cheeks, lips, and oral mucosa all make up the mucous membrane “skin” that lines the inside of the mouth. Individuals who have illnesses of the oral mucosa may get sores or ulcers in their mouths that hurt.

The philtrum and its pillars are anatomically a part of the upper lip. There are four distinct areas on the lip’s surface: the hairy skin, the vermilion border, the vermilion, and the oral mucosa. The typical lip shape changes with age and is impacted by one’s ethnicity.

The first part of the digestive system is the oral cavity, also referred to as the mouth or buccal cavity.

Anatomical study of human tooth structures is the focus of the discipline of dental anatomy.

Vermilion: The lips’ red portion. It is coated with a specific stratified squamous epithelium that continues into the gingival groove’s oral mucosa. Contrarily, the lips are also frequently used to allude to the vermilion itself.
