Explanation
The upper surface of the tongue is known as the dorsum. This term is commonly used in anatomy to refer to the top or superior surface of an organ or structure. In the case of the tongue, the dorsum is the part that is visible when the mouth is open. It is covered in papillae, taste buds, and lingual tonsils, and is responsible for various functions such as taste perception and speech articulation.
2.
The tongue is divided mainly into how many parts?
Correct Answer
B. 2
Explanation
The tongue is divided mainly into two parts. This is because the tongue is composed of two halves, known as the left and right sides. These sides are separated by a midline groove called the median sulcus. Each side of the tongue contains taste buds and is responsible for various functions such as taste perception, speech production, and swallowing.
3.
The oral part of the tongue is located at _______
Correct Answer
A. Front
Explanation
The oral part of the tongue is located at the front. This is because the front part of the tongue is responsible for taste sensation and manipulation of food during chewing and swallowing. The back part of the tongue, known as the base, is involved in speech production and helps in pushing food towards the throat. Therefore, the correct answer is front.
4.
The pharyngeal part of the tongue is located in ____________
Correct Answer
B. Back
Explanation
The pharyngeal part of the tongue is located in the back. This refers to the region of the tongue that is closest to the throat or pharynx. The tongue is divided into different parts, including the pharyngeal part, which is situated towards the posterior or back region of the oral cavity.
5.
What is the name of the tissue that separate the left and right side of the tongue?
Correct Answer
C. Lingual septum
Explanation
The correct answer is "Lingual septum." The lingual septum is the tissue that separates the left and right sides of the tongue.
6.
What is the name of the chemical that stimulate taste receptor cells?
Correct Answer
C. Tastants
Explanation
Tastants are the chemicals that stimulate taste receptor cells. These chemicals are responsible for activating the taste buds on our tongues and triggering the sensation of taste. When we consume food or drink, the tastants in them bind to specific receptors on the taste buds, sending signals to the brain that allow us to perceive different flavors. So, the correct answer is Tastants.
7.
Which of the following is a function of tongue?
Correct Answer
A. Mastication
Explanation
The tongue is responsible for the function of mastication, which is the process of chewing and breaking down food in the mouth. It helps in manipulating food within the oral cavity and mixing it with saliva, making it easier to swallow and digest. The tongue also plays a role in taste perception, speech production, and maintaining oral hygiene. Seige and coitus are not functions of the tongue.
8.
Which of the following is a tongue disease?
Correct Answer
C. Ankyloglossia
Explanation
Ankyloglossia is a tongue disease characterized by an abnormally short, thick, or tight frenulum, which is the tissue that connects the tongue to the floor of the mouth. This condition, also known as "tongue tie," can restrict the movement of the tongue and cause difficulties with speech, feeding, and oral hygiene. Treatment options for ankyloglossia may include speech therapy or surgical intervention to release the frenulum.
9.
Which of the following is not a tongue disease?
Correct Answer
B. Mouth nerosis
Explanation
Mouth nerosis is not a recognized tongue disease. While oral candidiasis, ankyloglossia, and burning mouth syndrome are all tongue-related conditions, mouth nerosis does not exist as a known medical term or condition.
10.
The tongue begins to develop in the ______________ week of embryogenesis from a median swelling
Correct Answer
C. Fourth
Explanation
The tongue begins to develop in the fourth week of embryogenesis from a median swelling. This is the stage when the structures of the tongue start to form, including the muscles and taste buds. The development of the tongue is a complex process that involves the migration and fusion of different tissue layers. By the fourth week, the tongue is starting to take shape and will continue to develop throughout the embryonic period.
