10 Questions
What is the function of neuroglia in the nervous system?
Supporting the neurones
Which part of a nerve cell transmits nerve impulses away from the cell body?
Axon
Why are nerve cells (neurones) easily damaged by toxins or lack of oxygen?
Because they are not insulated by myelin
Which part of a nerve cell is responsible for transmitting nerve impulses to the cell body?
Dendrites
In the nervous system, what does the neurilemma do?
Helps in regenerating nerve cells
What is the function of myelin sheath in a nerve cell?
Insulates and protects the axon
Why are nerve cells (neurones) not replaced when they die?
Due to their unique shape and structure
Which part of a neuron is described as an irregular-shaped, nucleated cell?
Cell body
What type of tissue supports neurons but does not transmit nerve impulses?
Neuroglia
Which part of a neuron helps to speed up nerve conduction by insulating the axon?
Myelin sheath
Test your knowledge on the components of the nervous system, including the Central Nervous System and Peripheral Nervous System, as well as the structure and function of nerve cells (neurones) and neuroglia. Learn about how nerve impulses are transmitted and the role of connective tissue in supporting neurones.
