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

Which of the following assist locomotion in snake

  1. Scutes

  2. Parapodia

  3. Flagella

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • Generally snakes have two kind of scales. Its top and sides are generally covered by smaller scales and The bottom of the snake is covered by short but very wide scales that look like rungs on a ladder.
  • These special scales at the bottom surface are called scutes.They form the belly of the snake and are integral in the snake’s ability to move.
  • Hence scutes assist in locomotion in snake.
  • So,the correct answer is 'Scutes'.

Locomotion is

  1. Voluntary movement

  2. Involuntary movement

  3. Nastic movement

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

  • Locomotion in biology pertains to the various movements of organisms (single-celled or multicellular organisms) to propel themselves from one place to another.

  • In multicellular animals, these movements include walking, running, jumping, crawling, climbing, swimming, flying, galloping, slithering, and so on. Voluntary muscles are the ones that you can control. 

  • Most of them move your bones around. If you want to run, walk, ride a bike, wave your arms around, or eat your favorite sandwich, it is your voluntary muscles by which u move your arms, legs, and body around. Hence, Locomotion is Voluntary movement.
     
So, the correct answer is 'Voluntary movement'.

The smallest muscle in the human body is

  1. Sartorius

  2. Stapedius

  3. Stapes

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

Stapedius is a muscle on the wall of the tympanic cavity of the middle ear. It is the smallest skeletal muscle in the human body. It acts reflexively in response to loud sounds by reducing excessive vibrations that may injure the internal ear. Thus the correct answer is option B.

Epicuticle in exoskeleton is made up of

  1. Lipoprotein

  2. Chitin

  3. Polysaccharide

  4. Fructolipase
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • The exoskeleton of animals within the phylum Arthropoda mainly consists of a coating called the cuticle.
  •  On the exterior surface of the cuticle is a thin, waxy layer called the epicuticle. 
  • The epicuticle is formed of three layers; the inner layer is the cuticulin, which is made from lipoproteins. Hence, Epicuticle in exoskeleton is made up of Lipoprotein
    • So, the correct answer is 'Lipoprotein'.

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

  1. Support

  2. Storage

  3. Excretion

  4. Movement
Reveal answer Fill a bubble to check yourself
C 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 skeleton serves six major functions: support, movement, protection, production of blood cells, storage of minerals and endocrine regulation. Hence, Excretion is not a biological function of the skeleton.
So, the correct answer is 'Excretion'.

Shedding of exoskeleton to replace it due to growth in body is called as

  1. Moulting

  2. Ecdysis

  3. Both A and B

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

  • Ecdysis is the moulting of the cuticle in many invertebrates of the clade Ecdysozoa.
  •  Since the cuticle of these animals typically forms a largely inelastic exoskeleton, it is shed during growth and a new, larger covering is formed.
  • The remnants of the old, empty exoskeleton are called exuviae. 
  • In arthropods, such as insects, arachnids and crustaceans, Moulting is the shedding of the exoskeleton (which is often called its shell), typically to let the organism grow. Hence, Shedding of the exoskeleton to replace it due to growth in the body is called ecdysis and moulting. 
So, the correct answer is 'Both A and B'.

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'.
