  2. Cuboidal

  3. Glandula

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

Bronchioles and fallopian tubes require ciliated epithelium to move particles or ova. Cilia beat rhythmically to transport mucus in respiratory tract and egg cells in the female reproductive tract.

(i) Each fasciculus (or bundle of muscle fibres) is surrounded by an epithelial tissue covering called perimysium
(ii) Multi unit smooth muscles are present in ciliary and iris muscles in the eyes and muscles of the walls of large blood vessels.
(iii) Columnar epithelium present in gastric glands, intestinal glands and pancreatic lobules, has a secretory role and is called as glandular epithelium.

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

Each fasciculus (bundle of muscle fibres) is surrounded by a connective tissue sheath called perimysium. Epithelial tissues arise from all the three primary germ layers of the embryo i.e., ectoderm, mesoderm and endoderm.

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

A) Testosterone is the male hormone which helps in the formation of sperms and male secondary sexual characters. 

B) The gestation period of a rabbit is about 27 to 30 days.
C) Bulbourethral gland helps in lubrication of the penis.
 D) Placenta secretes many hormones like human placental lactogen, human chorionic gonadotropin,  estrogens, progesterone, etc.
So the correct option is 'a,d'.

Multiple choice zoology adaptation terrestrial adaptation in animals terrestrial adaptations animal adaptations terrestrial adaptations in plants adaptation in terrestrial plants

To stay away from the intense heat during the day, they stay in _____ deep in the sand.

  1. Burrows

  2. Water

  3. Grass

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

To stay away from the intense heat during the day, they stay in burrows deep in the sand. These burrows stay cool in the day and hence protect these animals from hot weather.

Multiple choice biology windows of knowledge human nose nose nose : the olfactory organ

The forward section of the nasal cavity within and above each nostril, is called as

  1. Conchae

  2. Vestibule

  3. Turbinates

  4. All of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The forward section of the nasal cavity within and above each nostril is called as a vestibule. This region of the nose is lined by stratified squamous epithelium on which stiff hairs are present which prohibit entry of dust particles coming along with the inspired air. 

So, the correct answer is option B.

Multiple choice biology windows of knowledge human nose nose nose : the olfactory organ

Which of the following is responsible of olfactory reception?

  1. Eyes

  2. Nose

  3. Tongue

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

Nose is a most important sense organ of smell. The human nose can detect approximately 10,000 different odours. Nose also helps in the process of respiration.

Multiple choice biology windows of knowledge human nose nose nose : the olfactory organ

Above the uppermost concha, is the 

  1. Vestibule

  2. Olfactory bulb

  3. Conchae

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

Above the uppermost concha, is the olfactory bulb. It processes information about odours.
The entire nasal cavity is lined by a moist mucous membrane supplied with a large number of blood vessels.
The mucous membrane also has fine hair-like projections called the cilia which collect any debris entering the nasal cavity.
Apart from the cilia, the mucous membrane also has several cells. Some of these cells are called as secretory cells. Secretory cells secrete a thick, viscous fluid called as the mucous.

Multiple choice biology windows of knowledge human nose nose nose : the olfactory organ

The receptors present in the mucus membrane of nasal cavity are :

  1. Optic receptors

  2. Auditory receptors

  3. Olfactory receptors

  4. All the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The mucous membrane of the nasal cavity contains specialized receptors responsible for the sense of smell. These are known as olfactory receptors. Optic and auditory receptors are for vision and hearing respectively.

Multiple choice biology windows of knowledge human nose nose nose : the olfactory organ

Where are the receptors for smell located in the nose?

  1. Olfactory foramina

  2. Olfactory bulb

  3. Olfactory epithelium

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

The receptors for smell are located in the olfactory epithelium in the nose or nasal chamber thus, whatever comes near to our nose we can immediately sense its smell.

Multiple choice biology windows of knowledge human nose nose nose : the olfactory organ

Jacobson's organs are connected with

  1. Touch

  2. Smell

  3. Sight

  4. Hearing
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Jacobson's organ, also known as vomeronasal organ is an organ of chemoreception and part of olfactory system. These are present in many animals and help them to smell things. These are present in the form of patches of sensory cells in the nasal chamber. They lie close to the nasal bone. These organs are named after their discoverer,  Ludvig Levin Jacobson.
So, the correct answer is 'Smell'.

Nasal epithelium is formed of

  1. Columnar epithelium

  2. Keratinised epithelium

  3. Pseudostratified epithelium

  4. Glandular epithelium
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Nasal epithelium lies in the roof of nostril. It is pseudostratified epithelium which is composed of olfactory sensory neurons. The neurons are bipolar neurons having dendritic knobs that bear olfactory receptors. Pseudostratified epithelium means a single layer of cells. More appropriately, the nasal epithelium is pseudostratified columnar ciliated epithelium as the cells are columnar and have cilia projecting from the surface of cells.
 So, the correct answer is 'Pseudostratified epithelium'.
Multiple choice biology windows of knowledge human nose nose nose : the olfactory organ

Bowman's glands occur in

  1. Seminiferous tubules

  2. Pleural membrane

  3. Olfactory membrane

  4. Cardiac muscles
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Bowman's glands are also known as olfactory glands. They are present in olfactory mucosa of nasal cavity beneath the olfactory epithelium. The olfactory glands contain a secretory duct. The olfactory membrane is located over thick connective tissue called lamina propria. The olfactory glands secrete a mucous substance that protects the nasal epithelium from getting dry out.
So, the correct answer is 'Olfactory membrane'.
