Free Coordination and Control MCQs with Answers
1,687 Coordination and Control MCQs from Biology, each with the correct answer and a written explanation of why it is correct. Free and unlimited, with no account needed.
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.

- A. Thalamus
- B. Amygdala
- C. Hypothalamus
- D. Cerebellum
Explanation: Hypothalamus is a small but important region that maintains the balance of internal conditions in the body by hormone secretion .
Correct answer: Hypothalamus- A. They not only conduct impulses but also generate them
- B. They are not the only cellular component of nervous system
- C. They may show limited regenerative capabilities
- D. Like all the living cell, when they mature and divide to form similar cells
Explanation: They may show limited regenerative capabilities.So, the correct answer is: d) Like all the living cells, when they mature, they divide to…
Correct answer: Like all the living cell, when they mature and divide to form similar cells- A. Cervical
- B. Thoracic
- C. Lumbar
- D. All of these
Explanation: Option D is correct since cervical, thoracic, and lumbar are all regions of the spinal cord.
Correct answer: All of these- A. Brainstem
- B. Cerebrum
- C. Cerebellum
- D. Diencephalon
Explanation: Option D is correct since the brain is divided into the regions as shown below:
Correct answer: Diencephalon- A. Cranium
- B. Meninges
- C. Skull
- D. Ventricles
Explanation: Option B is correct since meninges provide the brain with nourishment and protection.
Correct answer: Meninges1066. Chlorosis, which is represented by yellowish hue on the leaves results from which of the following?
- A. Accumulation of toxic waste products in leaves
- B. Deficiency of chlorophyll
- C. Short supplies of mineral nutrients in the soil
- D. All of these
Explanation: Chlorosis can result from any of the following: the accumulation of waste products in leaves, a deficiency of chlorophyll, or a short…
Correct answer: All of these- A. Corpus callosum
- B. Midbrain
- C. Forebrain
- D. Hindbrain
Explanation: Only the hindbrain comprises the medulla oblongata, pons and the cerebellum.
Correct answer: Hindbrain1068. The large number of bundle fibres that joins the left and right cerebral hemispheres is called:
- A. Broca's area
- B. Lateral sulcus
- C. Corpus callosum
- D. Thalamus
Explanation: Correct C since Corpus callosum is a large bundle of more than 20 million myelinated nerve fibres that connect the two brain hemispheres…
Correct answer: Corpus callosum- A. Brain
- B. Central nervous system
- C. Peripheral nervous system
- D. Somatic division
Explanation: It is a fact that Spinal cord is part of the Central Nervous System.
Correct answer: Central nervous system- A. Frontal
- B. Parietal
- C. Temporal
- D. Occipital
Explanation: This is correct because the occipital lobes sit at the back of the head and are responsible for visual perception, including color, form…
Correct answer: Occipital- A. Myelinated dendrite
- B. Non-myelinated dendrite
- C. Non-myelinated axon
- D. Myelinated axon
Explanation: White matter is a component of the central nervous system, in the brain and spinal cord, and consists mostly of glial cells and myelinated…
Correct answer: Myelinated axon- A. Sensory neuron
- B. Motor neuron
- C. Connector neuron
- D. All of these options are correct
Explanation: The spinal cord consists of all of these types of cell bodies: sensory neurons, motor neurons, and connector neurons.
Correct answer: All of these options are correct- A. Act on external environment
- B. Regulate the internal environment
- C. Transmit motor information to the brain
- D. None of these options are correct
Explanation: The autonomic nervous system is a control system that acts largely unconsciously and regulates bodily functions such as the heart rate…
Correct answer: Regulate the internal environment- A. Dopamine
- B. Androgen
- C. Polypeptide
- D. Acetylcholine
Explanation: Acetylcholine is a neurotransmitter that is secreted at synapses outside the central nervous system.
Correct answer: Acetylcholine- A. Dendron
- B. Dendrites
- C. Axon
- D. Peripheral Branch
Explanation: Simply, nerve impulses travel through the dendron towards the cell body and are carried away from the cell body by the axon.
Correct answer: Axon- A. Insulin
- B. Glucagon
- C. Antidiuretic hormone
- D. Gastrin
Explanation: Insulin is released by B-cells in the islet of Langerhans in the pancreas and helps maintain the blood sugar level in the body.
Correct answer: Insulin- A. Negative feedback
- B. Positive feedback
- C. Inter-coordination
- D. Feedback mechanism
Explanation: Feedback mechanism involves response to a stimulus by means of an effector, which impacts conditions to bring them back to normal range.
Correct answer: Feedback mechanism- A. Dopamine
- B. Acetylcholine
- C. ADH hormone
- D. Oxytocin
Explanation: Parkinson's disease is a neurodegenerative disorder that affects movement.
Correct answer: Dopamine- A. Disturbance of Vision
- B. Constipation
- C. Decrease in Blood Pressure
- D. Increase in Heart Rate
Explanation: The sympathetic nervous system responds to dangerous/stressful situations by pumping blood at a faster rate to the muscles.
Correct answer: Increase in Heart Rate- A. Receptors
- B. Responses
- C. Effectors
- D. Transduction
Explanation: After a stimulus is received, the central nervous responds by sending a response via a motor neuron which transports the signal to the…
Correct answer: Effectors
