Question

In man the nasal cavity is separated from the buccal cavity by a bone which is known as:
A. Palate complex
B. Lingual bone
C. Soft palate
D. Hyoid apparatus

Answer 1

The oral cavity, often known as the mouth, is the first portion of the digestive tract. It has evolved to receive food through swallowing, break it down into little particles through mastication, and mix it with saliva. The boundaries are formed by the lips, cheeks, and palate. The teeth and tongue are housed in the oral cavity, which also receives salivary gland secretions.

Complete answer:
The nasal cavity is a wide, air-filled region in the centre of the face above and behind the nose. The nasal septum splits the cavity into two fossae, or cavities. Each cavity is made up of the continuations of one of the two nostrils. The paranasal sinuses surround the nasal cavity and drain into it.
In human anatomy, the mouth, also known as the oral cavity or buccal cavity, is the aperture through which food and air enter the body. The lips open to the outside and empties into the neck at the back; the lips, cheeks, hard and soft palates, and glottis define the mouth's borders.
The palate forms the roof of the mouth and separates the oral cavity from the nasal cavity
The palate is the oral cavity's roof. It's what separates the oral and nasal cavities. The hard palate's anterior section is supported by bone. The soft palate is made up of skeletal muscle and connective tissue at the back. The soft palate ends in a protrusion called the uvula on the backside.The soft palate and uvula migrate upward during swallowing to route food away from the nasal cavity and into the oropharynx.

So, the correct answer is option A.

Note: The initial segment of the digestive tube is the mouth cavity. Its principal role is to act as the entry to the alimentary canal, allowing salivation and the propulsion of the alimentary bolus into the pharynx to begin the digestion process.
