Multiple choice biology neural control and coordination structure of muscle skeletal muscles locomotion and movements

Which of the following is called as the response?

  1. Drawing out the hand

  2. Pricking with the pin

  3. Pin in the box

  4. Hand in the pocket
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A stimulus is something that causes a physiological response. The ability of an organism or organ to respond to external stimuli is called sensitivity. So, in the above example, the response to stimulus is drawing out hand and not pricking with pin, only pin or hand.

Therefore, the correct answer is option A.

When you are pricked with a pin, you will draw out your hand very fast. The stimulus is 

  1. Drawing out hand

  2. Pricking with a pin

  3. Pin

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

A stimulus is something that causes a physiological response. The ability of an organism or organ to respond to external stimuli is called sensitivity. So, in the above example, the stimulus is pricking with pin and not drawing out hand, only pin or hand. 

Therefore, the correct answer is option B.

The ability of an organism to respond to external stimuli is called as

  1. Sensitivity

  2. Homeostasis

  3. Metabolism

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • The stimulus(singular) is any change in the organism's internal or external environment that causes the organism to react.
  • The ability of an organism to respond to external stimuli is called sensitivity. For example, Plants grow towards light(external stimuli) sources, and if the direction of light is changed, the plant will also change its direction of growth to accommodate for survival.
  • So, the correct answer is 'Sensitivity'.
Multiple choice biology movement and locomotion in man types of muscles muscles muscles and their structure

Standing on tip toe is an example of

  1. Elevation

  2. Flexion

  3. Extension

  4. Retraction
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • Joints are points of contact between bones, or between bones and cartilages.
  • Synovial joints are characterized by the presence of a fluid-filled synovial cavity between the articulating surfaces of the two bones. These joints help in locomotion and many other movements. The hinge joint is a type of synovial joint.
  • extension refers to movement in the posterior direction. For example, when standing up, the knees are extended.
  • Hence standing on tiptoe(HINGE JOINT AT ANKLE) is an example of an extension.
  • So, the correct answer is 'Elevation'.

Which pair among the following is correct?

  1. Sweat- temperature regulation

  2. Saliva- sense of food taste

  3. Sebum- sexual attraction

  4. Humerus- hind leg
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The sweat on the surface of the skin is evaporated by the body heat. As the water is evaporated by heat released from the body, the body cools off. Each gram of water on the body surface absorbs about 0.58 calories of energy before evaporating, which is a significant source of heat loss.

Which of the following is not a reflex action?

  1. Salivation

  2. Sweating

  3. Withdrawal of hand when pinched by needle

  4. None of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

An automatic (involuntary) neuromuscular action excited by a defined stimulus is called reflex action. Sweating is not a reflex action. It is primarily a means of temperature regulation. But, Salivation and hand withdrawal because of the needle both are reflex actions.

D Correct answer
Explanation

Option 'D' is correct


Withdrawal reflex is the reflex that involves the withdrawal is response to stimulus. It is also known as pair withdrawal reflex. When pair receptors are stimulated, reciprocal innervation stimulate the flexons to withdrawal and inhibit the extensors.

Which one is correct about voluntary and involuntary movements?

  1. Voluntary movements- caused by skeletal muscle, Involuntary movements- caused by smooth muscle

  2. Voluntary movements- caused by smooth muscle, Involuntary movements- caused by skeletal muscle

  3. Voluntary movements- controlled by brain, Involuntary movements- controlled by organs

  4. Voluntary movements- controlled by organs, Involuntary movements- controlled by brain
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Voluntary movements are movements that are in direct control of the will of a person. These are controlled by skeletal muscles. For example walking, talking, dancing, etc. Involuntary movements are movements that are not in control of a person. They are generated by smooth striated muscle. For example, heart pumping, digestion, etc.

All movements in response to the environment can be carefully controlled.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Each kind of a change in the environment evokes an appropriate movement in response. When we want to talk to our friends in class, we whisper, rather than shouting loudly. So, the movement to be made depends on the event triggering it. Hence, such controlled movement must be connected to the recognition of various events in the environment, followed by only the correct movement in response. Therefore, the correct answer is option A.

Which of the following statements are true about reflex action?
i. It is a response activated after the activity or incident completes.
ii. It is an involuntary action.
iii. It is the sudden action in response to something in the environment.
iv. Impulse is carried to the brain directly for the response.

  1. (ii) and (iii)

  2. (ii) and (iv)

  3. Both A and B

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

Reflex action is an action which is given in response to something in the environment. It is an immediate action taken without much thinking and it does not have our control. The spinal cord is responsible for the response of the body because the impulse has not reached the brain till then. Therefore, the correct answer is option A.

Closing both the eyes when a torch light is flashed on one eye is a part of 

  1. Reflex action

  2. Chemotropism

  3. Hormonal control

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

  • The best-known reflex is the pupillary light reflex. If a light is flashed near one eye, the pupils of both eyes contract.
  •  Light is the stimulus, impulses reach the brain via the optic nerve, and the response is conveyed to the pupillary musculature by autonomic nerves. 

Therefore, the correct answer is option A.

Which is not a reflex action?

  1. Swallowing of food

  2. Shivering in cold

  3. Salivation at choicest food

  4. Closure of eyes lids by flashing light
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Swallowing food is a complex process involving both voluntary and involuntary muscle coordination, but it is not classified as a simple reflex action in the same way as blinking or shivering.
