Multiple choice evs the unique world of insects and animals sleeping time animal senses sense organs in animals

Identify the sense organs.

  1. Eyes

  2. Nose

  3. Tongue

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • Sense organs are organs of the body which responds to external stimuli by conveying impulses to the sensory nervous system. For example, eyes, nose, tongue, and ear.
  • We see with our eyes, we smell with our noses, we listen with our ears, we taste with our tongue, and we touch with our skin. Our brain receives signals from each of these organs and interprets them to give us a sense of what's happening around us.
  • So, the correct answer is 'All the above'.

Which of the following is a deep pressure receptor scattered in the dermis of our skin?

  1. Phonoreceptor

  2. Meissner's corpuscles

  3. Olfactory receptor

  4. Pacinian corpuscles
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

  • Photoreceptors - These are the structures responsible for light sensitivity.
  • Meissner's corpuscle - They are located in the upper surface of the skin and is sensitive to touch.
  • Olfactory organs - The organs that are responsible for the detection of smell.
  • Pacinian corpuscles - They are embedded deeply into the skin, below the layer of dermis or hypodermis. They act as the receptors for pressure on the skin.
So, the correct option is 'Pacinian corpuscles'.

Which of the following forms the inner lining of the mouth?

  1. Pleura

  2. Mucous membrane

  3. Pericardium

  4. Meninges
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The alimentary canal begins with an anterior opening the mouth, and it opens out posteriorly through the anus. The mouth leads to the buccal cavity or oral cavity. The oral cavity has 32 teeth and a muscular tongue. The buccal cavity is lined with mucous membrane, whose secretions keep mouth moist.

The structure, which prevents entry of food into wind pipe during swallowing in mammals is

  1. Larynx

  2. Glottis

  3. Epiglottis

  4. Pharynx
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The oral cavity leads into a short pharynx, which serves as a common passage for food and air. The oesophagus and the trachea (wind pipe) open into the pharynx. A cartilaginous flap, called as epiglottis, prevents the entry of food into the glottis opening of the wind pipe during swallowing.

Pharynx is the short tube leading to the stomach

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The pharynx is an organ found in vertebrates and invertebrates. In humans, the pharynx is a part of the digestive system and also of the conducting zone of the respiratory system. The conducting zone includes nose, larynx, trachea, bronchi and bronchioles and their function is to filter, warm and moisten air and conduct it into the lungs.
Therefore, the correct answer is option A.

The accessory organs in the digestive system are

  1. Tongue, Pancreas, Liver, Gallbladder and Salivary glands

  2. Tongue, Pancreas, Small intestine, Gallbladder and Salivary glands

  3. Tongue, Small intestine , Large intestine, Gallbladder and Salivary glands

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

An organ that helps with digestion but is not part of the digestive tract. The accessory digestive organs are the tongue, salivary glands, pancreas, liver, and gallbladder. Chemical digestion in the small intestine relies on the activities of three accessory digestive organs the liver, pancreas, and gallbladder. The digestive role of the liver is to produce bile and export it to the duodenum. The gallbladder primarily stores, concentrates, and releases bile. The pancreas produces pancreatic juice, which contains digestive enzymes and bicarbonate ions, and delivers it to the duodenum.

  1. Near surface of tongue

  2. At the back of throat

  3. Active throughout life

  4. Adenoids
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Adenoids, also called Pharyngeal tonsils, a mass of lymphatic tissue, similar to the tonsils, that is attached to the back wall of the nasal pharynx (i.e., the upper part of the throat opening into the nasal cavity proper). An individual fold of such nasopharyngeal lymphatic tissue is called an adenoid.

So, the correct option is 'Adenoids'.
