Nervous tissue is made up of neurons and neuroglial cells. Neuroglia protects and supports neurons. When a neuron is suitably stimulated, an electrical disturbance is generated which swiftly travels along its cytosol. The arrival of the disturbance at the neurons endings triggers stimulation or inhibition of adjacent neurons or other cells.

False Statements:
(i) Neuroglia makes up more than one-half of the volume of neural tissue in our body.
(iii) When a neuron is suitably stimulated, an electrical disturbance is generated which swiftly travels along its cytosol.

Neuroglia
Neuroglia, also known as glial cells, are non-neuronal cells that provide support and protection to neurons in the nervous system. There are various types of neuroglial cells, including astrocytes, microglia, oligodendrocytes, and Schwann cells. These cells make up about half of the volume of neural tissue in our body.

Functions of Neuroglia
- Provides structural support to neurons
- Maintain the chemical environment of the nervous system
- Insulate and protect neurons
- Phagocytosis of debris and pathogens

Neurons
Neurons are specialized cells that transmit information in the nervous system. They consist of a cell body, dendrites, and an axon. When a neuron is stimulated, an electrical impulse is generated that travels down the axon and triggers the release of neurotransmitters at the synapse.

Functions of Neurons
- Transmit information in the nervous system
- Integrate and process information
- Control bodily functions

False Statements
(i) Neuroglia makes up more than one-half of the volume of neural tissue in our body.
This statement is false. Neuroglia makes up about half of the volume of neural tissue in our body, not more than one-half.

(iii) When a neuron is suitably stimulated, an electrical disturbance is generated which swiftly travels along its cytosol.
This statement is false. When a neuron is suitably stimulated, an electrical impulse is generated that travels down the axon, not along its cytosol.

Conclusion
Therefore, option (c) is the correct answer as it states that only statement (iii) is false, while statements (i) and (iv) are true.
