Multiple choice biology nervous system of man reflex action innate and learned behaviour coordination in human beings- chemical control

A sudden and spontaneous reflex which leads to the quick pulling of hand on touching a hot object is generated by
I. Brain
II. Spinal cord
III. Sensory neurons
IV. Motor neurons

  1. I and IV

  2. III and IV

  3. I, III and IV

  5. I, II, III and IV
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A reflex action is defined as a spontaneous, involuntary, automated, nerve-mediated activity produced at the unconscious level  by stimulating specific receptors. In other words, a reflex action is a sensory impulse, automatically converted into a motor effect with the involvement of the central nervous system. These actions are sudden and automatic and take place even before one can feel the stimulus through the brain. The quick pulling of the hand on touching a hot object is an automated response to stimuli and is controlled and regulated by the spinal cord along with the sensory and motor neurons which connect the receptor and effector organs. Thus, the correct answer is option C.

Multiple choice biology nervous system of man reflex action innate and learned behaviour coordination in human beings- chemical control

The direction of response is opposite in which of the following reflex action?

  1. Biceps tendon relfex

  2. Knee jerk reflex

  3. Tricep tendon reflex

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

There are 4 types of spinal reflex action, namely the stretch reflex, the Golgi tendon reflex, the crossed extensor reflex and the withdrawal reflex. The direction of response is opposite in withdrawal reflex action. The withdrawal reflex is also called as flexor withdrawal reflex. It protects the body from damaging stimuli. It is polysynaptic. Hence, it causes the stimulation of sensory, association and motor neurons.  For example, when a person touches a hot iron, he withdraws his hand from it within fraction of seconds. In this, the heat stimulates temperature and danger receptors in the skin, triggering a sensory impulse that travels to the central nervous system. The sensory neuron synapses with interneurons and connects to motor neurons. These motor neurons send motor impulses to the flexors and allows withdrawal.

Thus, the correct answer is 'Withdrawal reflex.'

Multiple choice zoology the endocrine system introduction to human endocrine system endocrine system and hormone coordination in human beings- chemical control

Which one of the following is a voluntary action?

  1. Heart beat

  2. Salivation

  3. Chewing

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

The voluntary nervous system helps us take voluntary actions which are under the conscious control of the brain. Chewing is an action performed by us knowingly and is, therefore, a voluntary action.

Which one of the following is the example of the action of the autonomous nervous system ?

  1. Swallowing of food

  2. Pupillary reflex

  3. Peristalsis of the intestine

  4. Knee jerk response
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Peristalsis is an involuntary, rhythmic contraction of smooth muscles in the digestive tract, which is regulated by the autonomic nervous system. Swallowing involves both voluntary and involuntary phases, while pupillary reflex and knee jerk are somatic or autonomic reflexes, but peristalsis is the classic example of autonomic control of visceral organs.

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

Human body exhibits type of movement is

  1. Amoeboid

  2. Ciliary

  3. Muscular

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Movement is a characteristic feature of living organisms. The different types of movement exhibited by cells of the human body are: 
  • Amoeboid movement: Leucocytes present in the blood show amoeboid movement. 
  • Ciliary movement: Reproductive cells such as sperms and ova show ciliary movement.
  •  Muscular movements:  Muscle tissue found inside of the heart, digestive organs, and blood vessels serve to move substances throughout the body. Hence, The cells of the human body exhibits type of movement are Amoeboid, Ciliary and Muscular.
So, the correct answer is 'All of the above'.
Multiple choice biology locomotion and movements introduction to locomotion skeleton and joints movement in animals

The ability to move from one place to another is called as

  1. Locomotion

  2. Tropic movement

  3. Nastic movement

  4. None of the above
Reveal answer Fill a bubble to check yourself
A 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 ability to move from one place to another is called Locomotion.
So, the correct answer is 'Locomotion'.


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

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'.

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

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'.

Multiple choice nervous system of man major divisions of nervous system introduction to control and coordination neurons and synapses

Body coordination is maintained by

  1. Circulatory system

  2. Nervous system

  3. Endocrine system

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

Body coordination in complex organisms is managed by the nervous system (fast, electrical signals) and the endocrine system (slower, chemical signals via hormones). Both systems work together to maintain homeostasis.

When the person is alert, with open eyes and actively trying to solve some complex problem, the EEG shows ............ waves.

  1. Alpha

  2. Beta

  3. Delta

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

An electroencephalogram (EEG) is a test, that measures and records the electrical activity of the brain. Beta waves have a frequency of 13 to 30 cycles per second. These waves are normally found, when person is alert or have taken high doses of certain medicines, such as benzodiazepines.

Multiple choice evs seed becomes plant germination of seed seed germination journey of seed

Movement stimulated by external factor is

  1. Spontaneous movement

  2. Autonomic movement

  3. Physical movement

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

Autonomic movement is the spontaneous movement of the protoplasm seen in aquatic plants due to internal stimulus. It is not related to the external stimulus. Movement of cilia and flagella is an example of autonomic movement. A movement shown by a plant part in response to an external factor is called as paratonic movement. In this, the direction of movement is controlled by the direction of the stimulus. 

Thus, the correct answer is option D.
