Injury localised to the hypothalamus would most likely disrupt ______.

Detailed Solution: Question 1

The hypothalamus performs many functions which are important for the survival and enjoyment of life:

  • It serves as a link between 'mind' and body and between nervous and endocrine system.
  • The hypothalamus is responsible for hormone production. The hormone produced by this area govern body temperature thirst hunger, sleep, circulation rhythm, mood sex drive etc. This area of the brain also controls the functioning of the pituitary gland.
  • Thus, if any injury localised to the hypothalamus it will disrupt the complete regulation of body temperature and other activities.
Topic in NCERT: Hypothalamus and its Functions

Line in NCERT: "The hypothalamus contains a number of centres which control body temperature, urge for eating and drinking."

The myelinated nerve fibres are enveloped with Schwann cells, which form a myelin sheath around the axon. The gaps between the two adjacent myelin sheaths are called Nodes of Ranvier.

Topic in NCERT: NEURON AS STRUCTURAL AND FUNCTIONAL UNIT OF NEURAL SYSTEM

Line in NCERT: "The myelinated nerve fibres are enveloped with Schwann cells, which form a myelin sheath around the axon."

Detailed Solution: Question 5

The electrical potential difference across the resting plasma membrane is called as the resting potential.

Brain stem is the support system of brain and is the collective name for:

Detailed Solution: Question 6

  • Brain stem is the support system of brain and is the collective name for medulla, pons, midbrain. Brain stem also connect the brain with spinal cord.
  • The medulla oblongata controls vital functions such as breathing, heart rate, and blood pressure. 
    The pons is involved in the control of movement, sleep, and sensory analysis. 
    The midbrain plays a role in the regulation of motor movements, visual and auditory processing, and the sleep/wake cycle.
Topic in NCERT: BRAIN STEM

Line in NCERT: "Three major regions make up the brain stem; mid brain, pons and medulla oblongata."

Test: Neural Control & Coordination - 1 - Question 7
Save

The rise in stimulus-induced permeability to
a. Potassium ions
b. Sodium ions
c. Restoring RMP
d. Diffusion of potassium ions

Arrange them in order.

Detailed Solution: Question 7

The electrical potential difference across the resting plasma membrane is called as the resting potential.The rise in the stimulus-induced permeability to Na+ is extremely shortlived. It is quickly followed by a rise in permeability to K+. Within a fraction of a second, K+ diffuses outside the membrane and restores the resting potential of the membrane at the site of excitation and the fibre becomes once more responsive to further stimulation.

Topic in NCERT: Generation and Conduction of Nerve Impulse

Line in NCERT: "The rise in the stimulus-induced permeability to Na* is extremely short-lived. It is quickly followed by a rise in permeability to K*. Within a fraction of a second, K+ diffuses outside the membrane and restores the resting potential of the membrane at the site of excitation and the fibre becomes once more responsive to further stimulation."

Test: Neural Control & Coordination - 1 - Question 8

Where are the myelinated neurons found?

Detailed Solution: Question 8

Myelinated nerve fibres are found in spinal and cranial nerves. Unmyelinated nerve fibres are enclosed by a Schwann cell that does not form a myelin sheath around the axon and is commonly found in autonomous and the somatic neural system.

Topic in NCERT: NEURAL CONTROL AND COORDINATION

Line in NCERT: "Myelinated nerve fibres are found in spinal and cranial nerves."

Test: Neural Control & Coordination - 1 - Question 9

Assertion (A): The human brain functions as the primary control center for both voluntary and involuntary actions in the body.
Reason (R): The brain is protected by the skull and meninges, which provide physical barriers against external damage.

Detailed Solution: Question 9

Assertion (A): The human brain functions as the primary control center for both voluntary and involuntary actions in the body.

This statement is true. The brain is indeed responsible for controlling voluntary actions (like moving muscles consciously) and involuntary actions (like regulating heart rate and breathing).

Reason (R): The brain is protected by the skull and meninges, which provide physical barriers against external damage.

This statement is also true. The brain is encased in the skull, and it is further protected by the meninges, which are layers of protective tissue that cover the brain and spinal cord.

However, the Reason (R) does not directly explain the Assertion (A). While the protection of the brain by the skull and meninges is important for safeguarding the brain, it does not explain why the brain functions as the control center for voluntary and involuntary actions.

Thus, the correct answer is:

b) If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.

Which of the following statements is incorrect regarding electrical synapses?

Detailed Solution: Question 11

Electrical synapses are very rare in our system. At electrical synapses, the membranes of pre and post synaptic neurons are in very close proximity. Impulse transmission across an electrical synapse is always faster than chemical synapse.

Topic in NCERT: Transmission of Impulses

Line in NCERT: "Electrical synapses are rare in our system."

What are the short repeatedly branched fibres called?

Detailed Solution: Question 12

Dendrites  are short fibres which branch repeatedly and protrude out of the cell body. One of the fibres arising from the cell body is very long with a branched distal end and it is called Axon. 

Topic in NCERT: NEURON AS STRUCTURAL AND FUNCTIONAL UNIT OF NEURAL SYSTEM

Line in NCERT: "Short fibres which branch repeatedly and project out of the cell body are called dendrites."

Test: Neural Control & Coordination - 1 - Question 13
Save

What does each branch of axon terminate into?

Detailed Solution: Question 13

Each branch of an axon terminates into a synaptic knob. The axon is a long fibre which is branched at the end. Each branch terminates as a bulb-like structure called a synaptic knob. These knobs consist of some synaptic vesicles which contain some neurotransmitters like acetylcholine.

Topic in NCERT: Neuron as Structural and Functional Unit of Neural System

Line in NCERT: "Each branch terminates as a bulb-like structure called synaptic knob which possess synaptic vesicles containing chemicals called neurotransmitters."

Test: Neural Control & Coordination - 1 - Question 14
Save

Where are the specific receptors of neurotransmitters present?

Detailed Solution: Question 14

The released neurotransmitters bind to their specific receptors which are present on the post-synaptic membrane. The new potential developed may be either excitatory or inhibitory.

Topic in NCERT: Transmission of Impulses

Line in NCERT: "The released neurotransmitters bind to their specific receptors, present on the post-synaptic membrane."

Test: Neural Control & Coordination - 1 - Question 15
Save

Which of the following statements are correct?
(A). Depolarization of an axonal membrane is caused due to rise in stimulus-induced permeability to Na⁺ and its rapid influx into axoplasm.
(B). Diffusion of K⁺ outside the axonal membrane restores the resting potential of the membrane.
(C). Sodium-potassium pump maintains active transport of 2 Na⁺ outwards for 3 K⁺ into the axoplasm across the resting membrane.

Detailed Solution: Question 15

Depolarization of the axonal membrane happens due to an increase in Na⁺ permeability, which allows Na⁺ ions to rapidly enter the axoplasm, making Statement A correct. Statement B is also correct, as the diffusion of K⁺ out of the membrane restores the resting potential. Statement C is incorrect because the sodium-potassium pump moves 3 Na⁺ out for every 2 K⁺ in, not the other way around. Hence, the correct statements are A and B.
Topic in NCERT: Generation and Conduction of Nerve Impulse.
Line in NCERT: "The rise in the stimulus-induced permeability to Na* is extremely short-lived. It is quickly followed by a rise in permeability to K*. Within a fraction of a second, K+ diffuses outside the membrane and restores the resting potential of the membrane at the site of excitation and the fibre becomes once more responsive to further stimulation."
