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. Nucleus
- B. Axon
- C. Sarcolemma
- D. Cytoplasm
Explanation: The term "sarcolemma" specifically refers to the cell membrane of muscle cells (muscle fibers).
Correct answer: Sarcolemma- A. Mast cell
- B. Chondrocytes
- C. Osteocyte
- D. Nerve cell
Explanation: Nissl granules are found in nerve cells, specifically in the cell bodies and dendrites of neurons.
Correct answer: Nerve cell1343. The parts of neurons that perform basic cellular functions, such as protein synthesis are the:
- A. Soma
- B. Dendrites
- C. Axons
- D. Synaptic knobs
Explanation: Yes, the soma (cell body) of a neuron is indeed involved in protein synthesis.
Correct answer: Soma1344. The dendrites of a typical vertebrate motor neuron, compared to the neuron's axon are generally?
- A. Longer
- B. More myelinated
- C. Larger in diameter
- D. More branched
Explanation: The dendrites of a typical vertebrate motor neuron, compared to the neuron's axon, are generally more branched.
Correct answer: More branched- A. Dura matter
- B. Pericardium
- C. Pia matter
- D. Gray matter
Explanation: The dura mater is the outermost layer of the three meninges, the protective membranes that cover the brain and spinal cord.
Correct answer: Dura matter- A. Transformation of energy
- B. Conduction of impulse
- C. Receiving the impulse
- D. Providing energy for impulse
Explanation: Yes, the primary characteristic of an axon is the conduction of electrical impulses, known as action potentials, away from the neuron's…
Correct answer: Conduction of impulse- A. Above pia mater
- B. Inside blastocoel
- C. Above dura mater
- D. None of the above
Explanation: The subarachnoid space is a fluid-filled space that occurs above the pia mater, which is the innermost layer of the meninges.
Correct answer: Above pia mater- A. Axon
- B. Schwann cell
- C. Dendrite
- D. Cell body
Explanation: The correct part of the neuron that contains a nucleus and other organelles typical of a cell is the "d) Cell body".
Correct answer: Cell body- A. Cerebrum
- B. Cerebellum
- C. Cerebrul cortex
- D. Cerebral hemispheres
Explanation: Cerebellum is a part of hind brain that's why this option is different from others.
Correct answer: Cerebellum- A. Cerebrum
- B. Optic lobe
- C. Cerebellum
- D. Medulla oblongata
Explanation: The cerebrum is indeed the most developed part of the brain in humans, especially when compared to other animals.
Correct answer: Cerebrum- A. Hypothalamus
- B. Cerebellum
- C. Cerebral hemispheres
- D. Medulla oblongata
Explanation: The appetite and satiety centers in the brain are primarily located in the hypothalamus, which is a small region at the base of the brain…
Correct answer: Hypothalamus- A. Unipolar neuron
- B. Multipolar neuron
- C. Bipolar neuron
- D. None of the above
Explanation: The most prevalent type of neuron in the human body is the "Multipolar neuron." Multipolar neurons are the most common type of neuron…
Correct answer: Multipolar neuron- A. Cerebrum
- B. Medulla oblongata
- C. Cerebellum
- D. Corpus callosum
Explanation: The cerebellum plays a crucial role in coordinating and fine-tuning voluntary movements, maintaining balance, and facilitating motor…
Correct answer: Cerebellum- A. Somatic nervous system
- B. Parasympathetic nervous system
- C. Sympathetic nervous system
- D. Peripheral nervous system
Explanation: The explanation for this question will be added soon!
Correct answer: Somatic nervous system- A. Brain
- B. Spinal cord
- C. Brain stem
- D. Spinal nerves
Explanation: In summary, the correct answer is "d) Spinal nerves." Spinal nerves are not part of the central nervous system; they are components of the…
Correct answer: Spinal nerves- A. Sycon
- B. Euplectella
- C. Jelly fish
- D. Both a and b
Explanation: In summary, the correct answer is "d) Both a and b" - Sycon and Euplectella.
Correct answer: Both a and b- A. Heart
- B. Upper limbs
- C. Lower limbs
- D. Abdomen
Explanation: In summary, the correct answer is "b) Upper limbs." The brachial plexus is responsible for supplying nerves to the muscles and skin of the…
Correct answer: Upper limbs- A. Autonomic response
- B. Flight response
- C. Somatic response
- D. Reflex response
Explanation: The response of the sympathetic nervous system is often referred to as the "fight or flight" response.
Correct answer: Flight response- A. Act on external environment
- B. Regulate the internal environment
- C. Transmit motor information to brain
- D. None of these
Explanation: The autonomic nervous system (ANS) functions to "Regulate the internal environment" of the body.

- B. It is an amino acid derivative
- C. It is made from cholesterol
- D. It is a lipoprotein
Explanation: Antidiuretic hormone (ADH), also known as vasopressin, is a peptide hormone.
