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

  1. To make locomotion possible

  2. Protect organs of excretion

  3. Protect organs of digestion

  4. All of above

Show answer
Correct Option: D
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

Show answer
Correct Option: C
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'.
