All of the following are part of a neuron, except:
Correct answer: A. Astroglia
- A. Astroglia
- B. Soma
- C. Dendrite
- D. End bulb
Explanation
Astroglia, also known as astrocytes, are a type of glial cell found in the central nervous system (CNS). They provide structural support to neurons, regulate the extracellular environment, and contribute to synaptic function and plasticity. While astroglia are not part of the neuron itself, they are closely associated with neurons and play essential roles in supporting their function.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
