10 Questions
Which structure in the neuron contains Nissl bodies?
Cytoplasm
Where are Nissl bodies typically distributed within the neuron?
Throughout the cell body except at the axon hillock
Which part of the neuron shows a large euchromatic nucleus with a prominent nucleolus?
Nucleus
What is a characteristic feature of the axoplasm within a neuron's axon?
Few organelles such as neurofilaments and microtubules
In which region of the neuron is lipofuscin pigment typically found?
Cytoplasm
What is the direction of nerve impulses conducted by dendrites?
Toward the cell body
Which type of neurons have a single process that divides into two branches, one extending to a peripheral ending and the other toward the CNS?
Pseudo unipolar neurons
What is the main histological difference between neurons classified as stellate, pyramidal, and pyriform?
Shape of perikaryon
Which type of neurons regulate electrical changes of adjacent neurons but do not produce action potentials?
Anaxonic neurons
In terms of nerve impulse direction, what is the distinction between sensory and motor neurons?
Sensory neurons conduct impulses toward the CNS, while motor neurons conduct impulses away from the CNS.
Test your knowledge on the histological structure of a neuron, including the cell body (perikaryon or soma), axon, and dendrites. Learn about the components found in the cell body such as the nucleus, organelles, cytoplasm, and Nissl bodies.
