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.

Explanation: Motor neurons (MNs) are neuronal cells located in the central nervous system (CNS) controlling a variety of downstream targets.
Correct answer: Motor- A. Unipolar
- B. Associaton
- C. Motor
- D. Sensory
Explanation: Sensory neurons, also known as afferent neurons, transmit signals from sensory receptors (such as those for touch, temperature, pain…
Correct answer: Sensory- A. Afferent
- B. Multipolar
- C. Facilitated

Explanation: Association neurons, or interneurons, are exclusively found within the CNS, where they play crucial roles in integrating and processing…
Correct answer: Association- A. Unipolar
- B. Bipolar
- C. In the Peripheral Nervous System only
- D. Multipolar
Explanation: Bipolar neurons have two processes extending from the cell body: one axon and one dendrite.
Correct answer: Bipolar- A. Unipolar
- B. Bipolar
- C. In the Central Nervous System only
- D. Multipolar
Explanation: Multipolar neurons are characterized by having multiple processes extending from the cell body, including one axon and multiple dendrites.
Correct answer: Multipolar586. Microglia:
- A. From cerebrospinal fluid
- B. Only attach to capillaries to support neurons
- C. Are phagocytic
- D. Form the myelin of Central Nervous System neurons
Explanation: Microglia are the resident immune cells of the central nervous system (CNS).
Correct answer: Are phagocytic- A. Form cerebrospinal fluid
- B. Support neurons, by attaching to them and to capillaries.
- C. Are phagocytic
- D. Form the myelin of Central Nervous System axons.
Explanation: Astrocytes provide crucial support to neurons in various ways. They have numerous processes that extend to neurons, where they provide…
Correct answer: Support neurons, by attaching to them and to capillaries.- A. Reception
- B. Secretion
- C. Stimulation
- D. All of the above
Explanation: The correct option is all of these. The nervous system is involved in stimulation, reception, and secretion.
Correct answer: All of the above- A. Sensory
- B. Motor
- C. Afferent
- D. Sympathetic
Explanation: Motor neurons are responsible for transmitting signals from the central nervous system (CNS) to muscles or glands, causing them to…
Correct answer: Motor- A. Bipolar
- B. Multipolar
- C. Unipolar
- D. Apolar
Explanation: Unipolar neurons have a single process extending from their cell bodies, which later branches into two processes: one acts as an axon, and…
Correct answer: Unipolar- A. Nucleus
- B. Ganglion
- C. Tract
- D. Nerve
Explanation: In the central nervous system (CNS), a nucleus refers to a distinct group of neuronal cell bodies (gray matter) that are located deep…
Correct answer: Nucleus- A. Somatic
- B. Irritability
- C. Secretion
- D. Conductivity
Explanation: Irritability refers to the increased sensitivity of an organism or cell to stimuli.
Correct answer: Irritability- A. Nucleus
- B. Ganglion
- C. Tract
- D. Nerve
Explanation: Tracts are bundles of axons (nerve fibers) in the central nervous system (CNS) that are organized into distinct pathways and connect…
Correct answer: Tract- A. Phagocytosis
- B. Secretion of cerebrospinal fluid
- C. To form a connective tissue-like outer covering around ganglia
- D. Identical with that of Schwann cells of the Peripheral Nervous System
Explanation: Oligodendrocytes in the central nervous system (CNS) and Schwann cells in the peripheral nervous system (PNS) both provide support to…
Correct answer: Identical with that of Schwann cells of the Peripheral Nervous System- A. Sensory
- B. Motor
- C. Association
- D. Sympathetic
Explanation: An association neuron, also known as an interneuron, connects different regions within the same central nervous system (CNS).
Correct answer: Association- A. Integration of all systems
- B. Coordination of all systems
