Multiple choice biology locomotion and movements introduction to locomotion skeleton and joints movement in animals

Select the correct statement.

  1. All locomotion are movement but all movements are not locomotion.

  2. All movements are locomotion but all locomotion are not movement.

  3. All locomotion are different from all movements.

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

  • Locomotion occurs when a body changes its position from one place to another. 
  • Walking, running, climbing are the forms of locomotion. 
  • But some movements of our body parts like tongue, jaws does not result in any locomotion. 
  • Thus it can be said that all locomotions are movements but all movements are not locomotion. Hence, the correct statement. All locomotion is movement but all movements are not locomotion. 
 So, the correct answer is 'All locomotion is movement but all movements are not locomotion'.

How do muscles attached to the bones move the body?

  1. Automatically

  2. Pull movement only

  3. Push movement only

  4. Push and pull movement
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • The Muscles work by contraction and relaxation this represents that muscles can pull bones, but they can't push them back to the original position.
  • For this reason, muscles are often arranged in pairs that pull bones in opposite directions.
  • Hence muscles attached to the bones move the body by pull movement only.
  • So, the correct answer is 'Pull movement only'.

All movement of human body is coordinated and controlled by

  1. Axial system

  2. Nervous system

  3. Vertebral system

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

  • Your brain sends messages through your spinal cord and the peripheral nervous system to: control the movement of your arms and legs. control the automatic functions of your body, such as the operations of your heart, your organs and your glands. Hence, All movement of the human body is coordinated and controlled by the Nervous system.
So, the correct answer is 'Nervous system'.

Muscular and nervous excitability is lowered by which of the following?

  1. Na

  2. Mg

  3. Ca

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

  • High extracellular K+  leads to depolarization and ensuing inactivation of voltage-gated Na+ channels and loss of excitability in isolated muscles, exercise-induced loss of K+ is likely to reduce muscle excitability and thereby contribute to muscle fatigue. Hence, Muscular and nervous excitability is lowered by K.
So, the correct answer is 'K'.

Movement of whole animal from one place to another place is called as

  1. Skeletal movement

  2. Non-skeletal movement

  3. Movement

  4. Locomotion
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • Locomotion is when the movement of a part of the body leads to change in the position and location of the organism. 
  •  In multicellular animals, these movements include walking, running, jumping, crawling, climbing, swimming, flying, galloping, slithering, and so on. Hence, the Movement of the whole animal from one place to another place is called Locomotion. 
    • So, the correct answer is 'Locomotion'.

Which of the following is true of muscle contraction?

  1. H-zone expands

  2. I-band expands

  3. A-Band remains constant

  4. The sarcomeres expands
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  •  Upon muscle contraction, the A-bands do not change their length, whereas the I-bands and the H-zone shorten.
  •  This causes the Z lines to come closer together. The protein [tropomyosin] covers the myosin binding sites of the actin molecules in the muscle cell. Hence, A-Band remains constant  is true of muscle contraction
    •  So, the correct answer is 'A-Band remains constant'.

Locomotion is the characteristic feature of

  1. Plants

  2. Animal

  3. Microorganisms

  4. Both B and C
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

  • The movement of an organism from one place to another, often by the action of appendages such as flagella, limbs, or wings. 
  • In some animals, such as fish, locomotion results from a wavelike series of muscle contractions. 
  • Types of animal locomotion include walking, running, crawling, rolling, flying, climbing, swimming, skipping and jumping.
  •  Bacterial locomotion is of three types: Flagellar, Spirochaetal and Gliding movement. Hence, Locomotion is the characteristic feature of Animal and Microorganism.
 So, the correct answer is 'Both B and C'.

Major functions served by human skeleton are

  1. Support and movement

  2. Storage of ions

  3. Production of blood cells

  4. All of above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • The human skeleton is the internal framework of the body. It is composed of around 270 bones at birth this total decreases to around 206 bones by adulthood after some bones get fused together. 
  • The skeletal system performs vital functions like support, movement, protection, blood cell production, calcium storage and endocrine regulation that enable us to survive. Hence, Major functions served by human skeleton are Support and movement, Storage of ions and Production of blood cells.
So, the correct answer is 'All of the above'.

Which of the following is not related to locomotion?

  1. Setae

  2. Tendons

  3. Pseudopods

  4. Hydrostatic skelton

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

Setae are the bristle-like structures that serve in annelid locomotion. Tendon is a connective tissue structure that connects a muscle to another muscle, or a muscle to a bone and serves to transmit the force generated by a muscle during movement. Pseudopods are the outgrowth of the membrane and serve in locomotion in protists. A hydrostatic skeleton is found in many soft-bodied animals and is surrounded by muscles to serve in locomotion. A typhlosole is an internal fold of the intestinal wall found in some mollusks, lampreys and some annelids and echinoderms to serve as absorption surface. 

Therefore, the correct answer is option E.

The major advantage of bipedal locomotion is that it

  1. Releases forelimbs for other purposes

  2. Increases speed

  3. Reduces body weight

  4. Provides better support to the body
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Bipedalism is a form of terrestrial locomotion where an organism moves by means of its two rear limbs or legs. The major advantage of bipedal locomotion is that it releases forelimbs for other purposes.

So, the correct answer is 'Releases forelimbs for other purposes.'
