Animal Tissue and Anatomy Questions

Multiple choice

The plexus conjoined by the smallest splanchnic nerve is

  1. hepatic plexus

  2. lineal plexus

  3. suprarenal plexus

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

The renal plexus is made up of filaments from the celiac plexus, the aorticorenal ganglion, and the aortic plexus. It is also conjoined by the smallest splanchnic nerve.

Multiple choice

Which is the colourless transparent fluid present in ventricles of brain, central canal of spinal cord and in subarachnoid space?

  1. Blood

  2. CSF

  3. Lymph

  4. Leucocytes

  5. Plasma
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Cerebrospinal fluid (CSF) is a clear colourless body fluid produced in the choroid plexus of the brain. It acts as a cushion or buffer for the cortex providing a basic mechanical and immunological protection to the brain inside the skull and serves a vital function in cerebral autoregulation of cerebral blood flow.

Multiple choice

Which of the following prevents entry of food in the wind pipe?

  1. Glottis

  2. Epiglottis

  3. Larynx

  4. Pharynx

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The epiglottis is a flap-like structure located at the entrance of the larynx (wind pipe). When you swallow, it closes over the larynx to prevent food or liquid from entering the respiratory tract. The glottis is the vocal cord opening, larynx is the voice box, and pharynx is the shared passage for both air and food - none of these prevent entry.

Multiple choice

Which among these do/does not utilise the trapped air present in the gaps of soil?

  1. Nematode

  2. Bacteria

  3. Termite

  4. Earthworm

  5. Starfish
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

Starfish breathe by absorbing oxygen from special finger-like structures that are found on their body surface. They contain fuzzy patches which perform the same function of gills. Each one of those patches can contain dozens of papulae which are extended when the animal is comfortable and feels secure. Each of these permits the animal to collect oxygen for the starfish to breathe. They are generally found only on the top and side surfaces, generally not on the underside.

Multiple choice

Which of the following groups of organs belongs to external organs?

  1. Eyes, Nerves, Stomach, Intestine

  2. Heart, Lungs, Stomach, Brain

  3. Nose, Mouth, Ears, Eyes

  4. Nose, Lungs, Brain, Nerves

  5. Nerves, Lungs, Heart, Brain
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

External organs are responsible for protecting the body from most physical and environmental changes, and help us in sensing these changes. Nose, mouth, ears and eyes all are external organs and are present outside the body.

Multiple choice

Which of the following organs is/are known as 'Gateways of knowledge'?

  1. Body system

  2. Sense organs

  3. Legs

  4. Hands

  5. Fingers
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Sense organs help us to see, hear, smell, taste and feel things. These five senses are the gateways through which we experience everything that happens around. The things that the sense organs respond to are called stimuli.

Multiple choice

Epithelial tissues are the tissues that cover the whole surface of a body. Which of the following statements is/are not true?

a. Epithelial tissue has a free surface that faces either a body fluid or the outside environment. b. In them, the cells are compactly packed with little intercellular matrix. c. They perform the function of linking and supporting other tissues and organs of the body.

  1. Only a

  2. Only a and b

  3. Only b

  4. Only b and c

  5. Only c
Reveal answer Fill a bubble to check yourself
