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

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.'

The functions of axial skeleton are

  1. To make locomotion possible

  2. Protect organs of excretion

  3. Protect organs of digestion

  4. All of above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • The axial skeleton supports and protects the brain, spinal cord and many of the internal organs. 
  • It also provides sites for the attachment of other bones and muscles in the body, protect organs to excrete and digestion and also protects the nerves and blood vessels from the brain and spinal cord. Hence, The functions of the axial skeleton are To make locomotion possible, Protect the organs of excretion and Protect organs of digestion. 
    • So, the correct answer is 'All of the above'.

The motion that gives tetrapod mammals the greatest speed is with

  1. Front feet first

  2. Back feet first

  3. An asymmetrical gait

  4. All four feet together
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

  • Gait is the pattern of movement of the limbs of animals, including humans, during locomotion over a solid substrate.
  •  Most animals use a variety of gaits, selecting gait based on speed and energetic efficiency. 
  • Different animal species may use different gaits due to differences in anatomy that prevent the use of certain gaits. 
  • In a symmetrical gait, the left and right limbs of a pair alternate, while in an asymmetrical gait, the limbs move together. Asymmetrical gaits are sometimes termed "leaping gaits", due to the presence of a suspended phase. Hence, The motion that gives tetrapod mammals the greatest speed is with An asymmetrical gait.
So, the correct answer is 'An asymmetrical gait'.
