Multiple choice zoology life processes in living organism control of blood glucose parts of the brain kidney

Septum lucidum is a part of the

  1. Pseudocoel

  2. Metacoel

  3. Diocoel

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

Septum lucidum is a thin membrane of nervous tissue, that forms the medial wall of the lateral ventricles in the brain. The septum lucidum is located in the midline of the brain, between the two cerebral hemispheres. It is attached superiorly to the corpus callosum. It is attached to the anterior part of the fornix, and on either side of the structure are the two lateral ventricles. During foetal development, there is a space between the two laminae, called as the cavum septi pellucidi, which disappears during infancy. The cavum is occasionally referred to as the fifth ventricle (pseudocoel).

The cavity of diocoel is known as 

  1. I-ventricle

  2. II-ventricle

  3. III-ventricle

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

Ventricles are the open space or cavity in the brain which helps in relay of information. Diocoel is the cavity of the developing diencephalon, that later gives rise to the third ventricle of the brain. So, the correct answer is option C.

Multiple choice botany cell structure and organization membrane bound organelles cell: size and differentiation microscopy

When a fresh water protozan is placed in marine water

  1. The contractile vacuole disappears

  2. The contractile vacuole increases in size

  3. A number of contractile vacuoles appear

  4. The contractile vacuole remains unchanged
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Contractile vacuoles are membrane-bound organelles that pump excess water out of the protozoan. When the freshwater protozoan is placed in a marine environment it loses water due to exosmosis as salt concentration is high outside. The contractile vacuole disappears to prevent the loss of water from the organism because in the presence of contractile vacuoles the cell will be dehydrated. 

Thus the correct answer is option A.

Multiple choice bio-chemistry digestion liver functions of the liver secretory organs

The structural and functional units of liver are called

  1. Glisson's capsule

  2. Hepatic cells

  3. Hepatic cords

  4. Hepatic lobules
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
A. Glisson's capsule: It is a layer of dense connective tissue that surrounds the liver. 
B. Hepatic cells are the cells of liver and building blocks of liver.
C. Hepatic cords are the mass of cells (hepatocytes) which are arranged in irregular rows and columns.
D. Hepatic lobules are the minute, thin, profusely branched septa like trabeculae which extend inwards from the Glisson's capsule and divide each liver lobe into polyhedral units. These are the structural and functional units of liver.
So, the correct answer is 'Hepatic lobules'.
Multiple choice bio-chemistry digestion liver functions of the liver secretory organs

Glisson's capsule is associated with

  1. Liver

  2. Pancreas

  3. Lungs

  4. Kidney

  5. Adernal glands
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

  • Each lobule in the liver is made up of millions of hepatic cells, which are the basic metabolic cells. 
  • These lobules are held together by a fine, dense, irregular, fibroelastic connective tissue layer which extends from the fibrous capsule covering the entire liver known as Glisson's capsule.
  •  Glisson's capsule forms a layer of connective tissue surrounding the liver and ensheathing the hepatic artery, portal vein, and bile ducts within the liver. Hence, Glisson's capsule is associated with the liver.
So, the correct answer is 'liver'.

Multiple choice bio-chemistry digestion liver functions of the liver secretory organs

Gallbladder is found in

  1. Right lobe of liver

  2. Left lobe of liver

  3. In between the two lobes of liver

  4. Third lobe of liver
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

  • In vertebrates, the gallbladder is a small hollow organ where bile is stored and concentrated before it is released into the small intestine. 
  • In humans, the pear-shaped gallbladder present on the right lobe of the liver that lies beneath the liver, although the structure and position of the gallbladder can vary significantly among animal species. Hence, Gallbladder is found in
The right lobe of the liver.
So, the correct answer is 'right lobe of the liver'.

Multiple choice bio-chemistry digestion liver functions of the liver secretory organs

The liver is situated in upper part of the abdomen on the 

  1. Left side.

  2. Right side.

  3. Centre.

  4. It is not situated in the upper part of the abdomen.

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

The liver is the largest gland of the body weighing about 1.2 to 1.5 kg in an adult human. It is situated in the right upper corner of the abdominal cavity, just below the diaphragm and has two lobes. The hepatic lobules are the structural and functional units of liver containing hepatic cells arranged in the form of cords. Hence, the liver is situated in the upper part of the abdomen on the right side.
So, the correct option is 'right side'.

Liver of rabbit is made up of

  1. 4 lobes

  2. 6 lobes

  3. 5 lobes

  4. 7 lobes
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The rabbit's liver is divided in left and right regions by a deep cleft with the right and left lobes further divided into anterior and posterior lobules. The left lobes are left lateral, left central and a spigelian lobe. The right lobes are right central and caudate lobe.

Multiple choice bio-chemistry digestion liver functions of the liver secretory organs

Which of the following organs in mammals do not consist of a central 'medullary' region surrounded by a cortical region?

  1. Ovary

  2. Adrenal

  3. Liver

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

A. The ovaries are solid organs and are composed of connective tissue, the stroma. The stroma consists of an outer ovarian cortex and central ovarian medulla.

B. Adrenal: The adrenals are conical, yellowish bodies. Each has two distinct regions are called adrenal cortex and adrenal medulla.
D. Kidney:  The two regions of the kidney are outer region is called renal cortex and inner region is termed renal medulla.

So, the correct answer is 'Liver'.

How many lobes of liver are present in rabbit?

  1. 2

  2. 4

  3. 5

  4. 6
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The rabbit liver is situated in the epigastric region, between both costal arches, reaching the level of the right 7th and left 9th ribs. Rabit liver is divided into two right and left the region by deep cleft with right and left lobes. These lobes are further divided into the posterior and anterior region. It contains five lobes, as the right hepatic lobe, caudate and quadrate lobes are single, and the left hepatic one is separated in lateral and medial parts. Thus the correct answer is option C.

Peyer's patches are found in 

  1. Liver

  2. small intestine

  3. Large intestine

  4. Spleen

The liver of carnivore is larger than the herbivore because in carnivores

  1. Their body is also big

  2. The diet contains much more proteins so liver has to do more work

  3. The problem of phagocytosis by Kupffer cells are more

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

Animal flesh is composed of the most highly complex type of protein and requires vast amounts of uric acid to process. Uric acid is released into the system in amounts necessary to break proteins down into amino acids. Uric acid is a toxic substance and must be flushed out by the liver. Hence the carnivore's liver is designed with the capacity to eliminate ten times as much uric acid as the liver of man or other plant eaters.
