Which of the following is not a function of skeletal system?

  1. Production of eythrocytes

  2. Storage of minerals

  3. Production of body heat

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

  • The adult human skeletal system consists of 206 bones, as well as a network of tendons, ligaments and cartilage that connects them.
  •  The skeleton serves six major functions: support, movement, protection, production of blood cells, storage of minerals and endocrine regulation. Hence, Production of body heat is not a function of the skeletal system.
 So, the correct answer is 'Production of body heat

B Correct answer
Explanation

Skeletal muscle represents the majority of muscle tissue. It is the type of muscle, that powers movement of the skeleton. Their composition is 75-80 percent water, 15-20 percent proteins, 1 percent glycogen, 1 percent lipids and 1 percent mineral salts.

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

The water and electrolyte content of skeletal muscle was an average of 78.8 gm. of water, 4.96 milliequivalent (meq.) of sodium, 8.32 meq. of potassium, 4.04 meq. of chloride, 0.445 meq. of magnesium, and 3.88 meq. of phosphorus per 100 gm. of wet tissue or muscle. Hence, the percentage of water content in skeletal muscle can vary from 75-78%.

Which one of the following is the correct description of a certain part of a normal human skeleton?

  1. Parietal bone and the temporal bone and the skull are joined by fibrous joint.

  2. First vertebrae is axis, which articulates with the occipital condyles.

  3. The 9th and 10th pairs of ribs are called the floating ribs.

  4. Glenoid cavity is a depression to which the thigh bone articulates.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A suture is a type of fibrous joint, which only occurs in the skull. These joints are synarthroses. One parietal bone is located on each side of the skull just behind the frontal bone. The temporal bones are situated at the sides and base of the skull, and lateral to the temporal lobes of the cerebrum.

Which of the following is not a function of the skeleton system?

  1. Production of erythrocytes

  2. Storage of minerals

  3. Production of body heat

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

Skeletal system is the articulation bones to give perfect shape to the body. They help in locomotion by attaching with muscles. 

Bones are made up of minerals like Ca++ and po4-. So they act as store house of minerals. 
Bones have bone marrow which contain stem cells. Stem cells are the precursors of blood form cells like RBC, WBC and platelets,
Skeletal system doesn't play any role in production of heat. Heat production is regulated by metabolic processes. 
So the correct option is C.

Multiple choice evs excretion in living organisms other systems in the body excretory system in human human excretory organs

Which of the following are excretory products in animals?

  1. Urea

  2. Uric acid

  3. Ammonia

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

In animals, the main excretory products are, Ammonia- protozoans, crustaceans, platyhelminths, cnidarians, poriferans, echinoderms, fishes, larvae/tadpoles of amphibians are ammonotelic. Urea -cartilaginous fish, few bony fishes, adult amphibians and mammals including humans are uricotelic, Uric acid-terrestrial arthropods (including insects), lizards, snakes, and birds are uricotelic.

So, the correct answer is 'All the above'

The process of filtering the blood by artificial kidney is known as

  1. Dialysis

  2. Excretion

  3. Secretion

  4. Assimilation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
The process of filtering the blood by the artificial kidney is known as dialysis. It is a method of removing excess water, nitrogenous wastes (urea), toxins from the blood in the patient who is rapidly developing loss of kidney function. It is also called renal replacement therapy.
So, the correct answer is 'Dialysis'.

The urinary opening is known as

  1. Urinary bladder

  2. Ureter

  3. Urethera

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
The urinary opening is known as Urethra. It is a long tube which connects urinary bladder to the urinary meatus for removal of urine from the body. In males, urethra travels through the penis and meet the urethral meatus located at the tip of the penis. In females, urethra connects to the urethral meatus above the vagina.
So, the correct answer is 'Urethra'.

The major excretory product in humans is 

  1. Urea

  2. Ammonia

  3. Uric acid

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
The major excretory product in humans is urea. The first step in the conversion of amino acids from protein into metabolic waste in the liver is the removal of the alpha-amino nitrogen, which results in ammonia. Because ammonia is toxic, it is converted into urea by humans. The urea is excreted in urine by the kidneys.
So, the correct answer is 'Urea'.

The excretory product in fishes are 

  1. Ammonia

  2. Uric acid

  3. Urea

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
The excretory product in fishes is ammonia. Usually, food for fish is rich in proteins. And the end product of protein catabolism is ammonia. So fishes excrete ammonia. As the fishes excrete ammonia as excretory waste they are called ammonotelic.
So, the correct answer is 'Ammonia'.
