- Nervous System consists of:
A. Brain
B. Spinal Cord
C. Nerves
D. All the above
Ans. D
Explanation:┬аThe brain and the spinal cord along with nerves constitute the nervous system. - Which of the following statement is correct about Cerebellum?
A. It regulates the muscular movement for locomotion.
B. It is a part of brain.
C. Both A and B
D. Neither A nor B
Ans. C
Explanation:┬аCerebellum consists of large mass having ridges and furrows, situated above and behind the medulla and attached to cerebrum. It regulates muscular movement for locomotion. It is a part of brain. - Which nerves are attached to the brain and emerge from the skull?
A. Cranial Nerves
B. Spinal Nerves
C. Thoracic Nerves
D. Sacral Nerves
Ans. A
Explanation:┬аCranial Nerves are attached to the brain and emerge from the skull. - ┬аName the system that controls every activity that you do?
A. Nervous System
B. Exocrine System
C. Endocrine System
D. Respiratory System
Ans A
Explanation:┬аIn vertebrates, Nervous System consists of two main parts Central Nervous System (CNS) and Peripheral Nervous System (PNS). CNS consists of brain and spinal cord whereas PNS consists of nerves. We can say that brain is the boss of our body; it controls everything that you do. - What is the unit of Nervous system?
A. Brain
B. Spinal Cord
C. Neuron
D. Nerves
Ans. C
Explanation:┬аThe units which make up the nervous system are called nerve cells or neurons. Therefore, neuron is the functional and structural unit of nervous system. Neuron is the largest cell in the body. - A microscopic gap between a pair of adjacent neurons over which nerve impulses pass when going from one neuron to the next is called:
A. Neurotransmitter
B. Synapse
C. Axon
D. None of the above
Ans. B
Explanation:┬аA microscopic gap between a pair of adjacent neurons over which nerve impulses pass when going from one neuron to the next is called synapse. - In our body involuntary actions are controlled by:
A. Medulla in Hindbrain
B. Medulla in Forebrain
C. Medulla in Spinal Cord
D. Medulla in Midbrain
Ans. A
Explanation:┬аMedulla in Hindbrain controls the involuntary actions of our body. - Those reflex actions which involve brain are called:
A. Stimulus
B. Cerebral reflexes
C. Spinal reflexes
D. Reflex arc
Ans. B
Explanation:┬аThose reflex actions which involve brain are called cerebral reflexes. They occur in the organs present in the head because these organs are directly connected to the brain. - Pons, cerebellum and medulla are part of which brain?
A. Forebrain
B. Midbrain
C. Hindbrain
D. None of the above
Ans. C
Explanation:┬аThe brain is broadly divided into three regions: forebrain, midbrain and hindbrain. The forebrain mainly consists of cerebrum. The midbrain does not have any further divisions. The hindbrain consists of three centres called pons, cerebellum and medulla. - Spinal Cord originates from which part of the brain?
A. Cerebellum
B. Medulla
C. Pons
D. Cerebrum
Ans. B
Explanation:┬аFrom Medulla Spinal cord originates. Medulla controls various involuntary actions such as heart beat, breathing, blood pressure and peristaltic movements of alimentary canal. Medulla is also the controlling centre for reflexes such as swallowing, coughing, sneezing, secretion of saliva and vomiting.
