FAQs on Incisors, Canines, Premolars & Molar Teeth Video Lecture - Biology for JAMB

1. What are the different types of teeth in humans?
Ans. In humans, there are four types of teeth: incisors, canines, premolars, and molars. Incisors are used for cutting and biting food, canines are sharp and used for tearing food, premolars help in grinding and chewing, and molars are the largest and help in crushing and grinding food.
2. How many incisors do humans have?
Ans. Humans have a total of eight incisors, four in the upper jaw and four in the lower jaw. These teeth are located in the front of the mouth and are used for biting and cutting food.
3. What is the function of canines in humans?
Ans. Canines, also known as cuspids, are the pointed teeth located on either side of the incisors. Their main function is to tear and grip food, helping in the initial breakdown of food during chewing. Canines also play a vital role in speech production.
4. How many premolars and molars do adults have?
Ans. Adults have a total of eight premolars, four in each jaw. These teeth are located between the canines and molars and are used for grinding and chewing food. Additionally, adults have twelve molars, six in each jaw. The molars are the largest teeth and are responsible for crushing and grinding food.
5. Why are molars important for proper digestion?
Ans. Molars play a crucial role in proper digestion. Their large surface area and sturdy structure allow them to grind and crush food into smaller pieces, making it easier for the digestive enzymes in the stomach to break down the food further. Efficiently broken down food promotes better nutrient absorption and digestion.
