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.

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.

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.

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'.

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'.
Multiple choice biology excretory system of human artificial kidney kidney transplant disorders of kidney

In which of the following area is the incision made to transplant a kidney?

  1. Lower abdomen

  2. Upper abdomen

  3. Aortic vein

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

In a standard kidney transplant, the donor kidney is placed in the iliac fossa, which is located in the lower abdomen, rather than in the original anatomical position of the kidneys.

Multiple choice bio-chemistry nervous system of man introduction to brain body fluid central nervous system

The space between the layers of the brain is filled with fluid is called ...........

  1. Cerebrospinal fluid

  2. Pleural fluid

  3. Synovial fluid

  4. Aqueous humour
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
A. Cerebrospinal fluid is a clear liquid produced within spaces in the brain called ventricles. Like saliva, it is filtrate of blood. It is also found inside the subarachnoid space of the meninges which surrounds both the brain and spinal cord.
B. Pleural fluid is a thin translucent fluid that fills the cavity between the parietal(outer) and visceral(inner) pleural layers surrounding the lungs.
C. Synovial fluid also called synovia is a vicious, non- Newtonian fluid found in the cavities of synovial joints.
D. Aqueous is a thin, watery fluid located in the anterior and posterior chambers of the eye.
So, the correct answer is "Cerebrospinal fluid".

Stratum germinativum is an example of which kind of epithelium?

  1. Columnar

  2. Squamous

  3. Cuboidal

  4. Ciliated
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
The stratum germinativum is the deepest layer of the five layers of the epidermis. The stratum basale is a single layer of columnar or cuboidal cells.
So, the correct option is 'cuboidal'.
