Animal Tissue and Anatomy Questions

Multiple choice

In the abdominal cavity, the ovaries are held in position by tissues known as:

  1. mesovarium

  2. mesorchidium

  3. mesenteries

  4. suspensory ligaments
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The mesovarium anchors the ovaries to the posterior leaf of the broad ligament. The mesorchidium suspends testes, mesenteries support intestines generally, and suspensory ligaments connect ovaries to the lateral abdominal wall but don't provide the primary attachment.

Multiple choice

Ascaris is found in:

  1. body cavity

  2. lymph nodes

  3. tissue

  4. alimentary canal

  5. blood vessels
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Ascaris is an intestinal nematode parasite found in the human alimentary canal (small intestine). It inhabits the lumen of the digestive system. Body cavity, lymph nodes, tissue, and blood vessels are not its habitat.

Multiple choice

Corti's organs is present in:

  1. Reisner's membrane

  2. scala vestibuli

  3. Basilar's membrane

  4. Middle lamella

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

The organ of Corti is the sensory organ for hearing located on the basilar membrane within the cochlea of the inner ear. It contains hair cells that convert sound vibrations into neural signals. It is not associated with Reissner's membrane, scala vestibuli (one of the cochlear chambers), or middle lamella (a plant cell structure).

Multiple choice

Which of the following statements is the incorrect description of the sturcture mentioned?

  1. Larynx: Area at the top of the throat that contains the vocal cords and produces vocal sounds.

  2. Pharynx: Region of the digestive tract between the mouth and the oesophagus that serves as a passageway for food and air.

  3. Trachea: Tube that extends from the larynx to the bronchi and carries air to the lungs.

  4. Epiglottis: Opening between the vocal cords in the larynx.

  5. Pleura: Serous membrane that encloses the external surface of the lungs.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Epiglottis is a thin piece of tissue at the back of the tongue that covers the opening of the larynx and the trachea while swallowing. Glottis is the opening between the vocal cords in the larynx.

Multiple choice

Hyoid apparatus in frog provides support to

  1. tongue

  2. lower jaw

  3. lungs

  4. upper jaw
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The hyoid apparatus in frogs is a specialized structure of modified branchial arch elements that provides attachment and support for the tongue muscles. This allows the frog to rapidly project its tongue outward to capture prey. The hyoid acts as a movable base for tongue protraction during feeding.

Multiple choice

The structure which prevents the entry of food into the wind pipe is:

  1. larynx

  2. glottis

  3. epiglottis

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

The epiglottis is a leaf-shaped cartilage flap that covers the trachea (windpipe) during swallowing, preventing food or liquids from entering the respiratory tract. The larynx contains the vocal cords, the glottis is the opening between them, and tonsils are lymphatic tissue - none of these prevent food entry.

Multiple choice

Which of the following structures is present in the right ventricle of mammals?

  1. Orifice of pulmonary trunk

  2. Orifice of the coronary sinus

  3. Orifice of the inferior vena cava

  4. Orifice of the superior vena cava

  5. Orifice of the tensor veli palatini
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Orifice of pulmonary trunk is also known as the opening of pulmonary trunk in mammals. It is the opening between the pulmonary trunk and the right ventricle of the mammalian heart.

Multiple choice

Meissner's corpuscles are the type of mechanoreceptors present in different parts of the body. Which of the following parts of penis contains these receptors?

  1. Cumulus

  2. Acrosome

  3. Corona

  4. Head

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

Meissner's corpuscles are the touch receptors located near the surface of the skin in human beings.The foreskin contains sensory receptors called Meissner corpuscles. These nerves provide pleasure as well as fine sensory perception.

Multiple choice

Gall bladder epithelium is

  1. simple squamous

  2. simple cuboidal with stereocilia

  3. simple columnar

  4. simple columnar with brush border
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The gall bladder lining consists of simple columnar epithelium with microvilli on the apical surface, which increases surface area for absorption. These microvilli are sometimes described as a brush border, though this term is more commonly used for intestinal epithelium.

Multiple choice

From which one of the following, the ureter develops?

  1. Metanephros

  2. Mesonephros

  3. Mesonephric duct

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

The ureter develops from the ureteric bud, which is an outgrowth of the mesonephric duct (Wolffian duct). This embryological origin is important for understanding congenital anomalies of the urinary system.
