MCQs on Nervous System

( Class 10 Concise ICSE Selina Solutions Ch-10 )

Que-1: The basic structural and functional unit of brain is:

1. Cyton
2. Nephron
3. Axon
4. Neuron

Sol: Neuron

Hint: The basic structure of nervous system is Neuron.

Que-2: Which of the following structures is absent in nerve cells ?

1. Nucleus
2. Cytoplasm
3. Centrosome
4. Neurilemma

Sol: Centrosome

Hint: Centrosome is absent in nerve cells due to lose their ability of division.

Que-3: The number of cranial and spinal nerves in a human being are respectively :

1. 31, 12 pairs
2. 32, 21 pairs
3. 12, 31 pairs
4. 31, 21 pairs

Sol: 12, 31 pairs

Hint: The human body has 12 pairs of cranial nerves and 31 pairs of spinal nerves.

Que-4: Which part of the brain controls the posture of our body?

1. Cerebrum
2. Medulla oblongata
3. Cerebellum
4. Pons

Sol: Cerebellum

Hint: The cerebellum, located at the back of the brain, controls posture, balance, and equilibrium:

Que-5: The central cavity of the brain is termed as :

1. Thalamus
2. Ventricle
3. Hypothalamus
4. Auricle

Sol: Ventricle

Hint: The cavity in the skull that houses the brain is called the cranial cavity, or intracranial space. These ventricles are filled with cerebrospinal fluid (CSF), which helps protect and cushion the brain.

Que-6: Nissl’s granules are found in the cytoplasm of :

1. Nerve cell
2. Dendrons
3. Axon
4. Dendrites

Sol: Nerve cell

Hint: Nissl’s granules are found in the cytoplasm of the cell body of neurons.

Que-7: The thin delicate middle layer of meninges is termed as :

1. Choroid
2. Dura mater
3. Arachnoid
4. Pia mater

Sol: Arachnoid

Hint: The thin, delicate middle layer of the meninges is called the Arachnoid. It is also the middle layer of the meninges.

Que-8 Any factor that can bring a change in the body of an organism is called:

1. Response
2. Stimulus
3. Reflex
4. Impulse

Sol: Stimulus

Hint: The body of an organism response to stimulus which is any agent or an environmental change.

Que-9: Gyri and sulci are richly found in :

1. Renal cortex
2. Cerebral cortex
3. Spinal cortex
4. Adrenal cortex

Sol: Cerebral cortex

Hint: Gyri and sulci are found in the cerebral cortex of the brain:

Gyri: Ridges on the cerebral cortex

Sulci: Folds on the cerebral cortex

Que-10: The white matter of cerebrum mainly consists of :

1. Cytons
2. Dendrons
3. Axons
4. Dendrites

Sol: Axons

Hint: The white matter of the cerebrum is mainly made up of myelinated axons, which are extensions of nerve cells, or neurons.
