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: They are the basic structure capable of transmission of impulse.

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

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

Sol: Centrosome

Hint: The centrosome is absent in nerve cells because they lose their ability to divide after differentiation.

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: There are 12 pairs of cranial nerves and 31 pairs of spinal nerves in the human body.

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 is primarily responsible for coordinating and controlling voluntary movements, as well as maintaining posture and balance.

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

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

Sol: Ventricle

Hint: The central cavities of the brain are called ventricles, and they 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: Nerve cells have many free ribosomes and ribosomes associated with the endoplasmic reticulum, giving the cell a granular appearance.

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 arachnoid is 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: A stimulus is any agent or environmental change that initiates a response in the body.

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: In the cerebral cortex, the folds of gray matter are called gyri, and the grooves are called sulci.

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

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

Sol: Axons

Hint: Axons are covered with a myelin sheath, which gives them a white color.
