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. Hypothalamus
- B. Bones
- C. Skin
- D. Muscles
Explanation: Sensory neurons have pain-sensitive endings in the skin, as the skin is a sensory organ.
Correct answer: Skin- A. 2
- B. 3
- C. 4
- D. 5
Explanation: The forebrain can be divided into three functional parts, namely the thalamus, the limbic system, and the cerebrum.1.
Correct answer: 3- A. Corpus callosum
- B. Hippocampus
- C. Medulla
- D. Thalamus
Explanation: The medulla oblongata is responsible for controlling breathing, heart rate, and blood pressure. It is present in the hindbrain.
Correct answer: Medulla- A. Central nervous system
- B. Parasympathetic nervous system
- C. Sympathetic nervous system
- D. Autonomic system
Explanation: Smooth muscles, cardiac muscles, and organs are controlled by the autonomic nervous system, as they do not require conscience control and…
Correct answer: Autonomic system- A. Amygdala
- B. Broca's area
- C. Hypothalamus
- D. Occipital lobe
Explanation: Option A: The amygdala is commonly thought to form the core of a neural system for processing fearful and threatening stimuli (4)…
Correct answer: Broca's area- A. Cerebellum
- B. Pons
- C. Medulla oblongata
- D. Brain stem
Explanation: The medulla oblongata is the lowermost part of the brainstem, and it is responsible for regulating vital functions such as breathing…
Correct answer: Medulla oblongata- A. Adrenaline
- B. Serotonin
- C. Dopamine
- D. Acetylcholine
Explanation: The main neurotransmitter for synapses that lie outside the central nervous system is Acetylcholine.
Correct answer: Acetylcholine- A. Myelinated impulse
- B. Jumping impulse
- C. Saltatory impulse
- D. All of these
Explanation: In myelinated neurons, the impulse jumps from node to node. This is called a saltatory impulse.
Correct answer: Saltatory impulse- A. Pons of medulla
- B. Thalamus and limbic system
- C. Pons and medulla
- D. Hypothalamus and limbic system
Explanation: The diencephalon is a part of the brain that is located between the cerebrum and the midbrain. It is made up of four main parts, i.e.
Correct answer: Thalamus and limbic system- A. It is voluntary
- B. It is involuntary
- C. It is found in higher animals
- D. All of these
Explanation: Reflex action is a sudden and involuntary response to stimuli. It helps organisms to quickly adapt to an adverse circumstance that could…
Correct answer: It is voluntary- A. 8
- B. 10
- C. 12
- D. 15
Explanation: Spinal nerves branch off from the spinal cord to innervate the rest of the body.
Correct answer: 8- A. Medulla
- B. Thalamus
- C. Hypothalamus
- D. Hippocampus
Explanation: The hippocampus is required for learning. The hippocampus is a part of the brain located in the medial temporal lobe.
Correct answer: Hippocampus- A. Axons
- B. Synapse
- C. Neuron somas
- D. None of these
Explanation: The explanation for this question is as follows: The Outer zone is white matter and contains axons of sensory neurons in the dorsal column…
Correct answer: Axons- A. Stretch reflex
- B. Spinal reflex
- C. Golgi tendon reflex
- D. Myotatic reflex
Explanation: The stretch reflex is also called the myotatic reflex. The stretch reflex or myotatic reflex refers to the contraction of a muscle in…
Correct answer: Myotatic reflex- A. Gibberellins
- B. Cytokinins
- C. Auxins
- D. Ethene
Explanation: The correct answer is gibberellins. Gibberellins are plant hormones that promote flowering in both short-day and long-day plants.
Correct answer: Gibberellins- A. Inhibits peristalsis
- B. Sweat secretion
- C. Constriction of Pupils
- D. Dilates Bronchioles
Explanation: In summary, the correct answer is "c) Constriction of Pupils." The parasympathetic nervous system is responsible for causing pupil…
Correct answer: Constriction of Pupils- A. Nephrons
- B. Myoid cells
- C. Neurons
- D. None of these options are correct
Explanation: OPTION C: Neurons are the basic structural and functional unit of the nervous system.
Correct answer: Neurons- A. Swallowing
- B. Vision
- C. Memory
- D. Water balance
Explanation: The hypothalamus maintains homeostasis and contains centers for regulating hunger, sleep, thirst, body temperature, water balance, blood…
Correct answer: Water balance- A. 10-20 cm
