There are <em><u>four types of neuroglia</u></em> found within the central nervous system:
<u>Astrocytes</u> :
It maintains the blood brain barrier and preserve the chemical environment by recycling ions and neurotransmitters.
<u>Oligodendrocytes</u> :
The myelinate axons in the central nervous system and provide an overall structural framework.
<u>Ependymal cells</u> :
The line ventricles (brain) and central canal (spine) and are involved in the production of cerebrospinal fluid.

Stability is defined as the ability of the body to maintain an equilibrium posture and the movements supporting and balancing the body.
The activities that improve the stability are:
1. The center of gravity is lowered and placed near the base of support to increase the stability.
2. The distance between the feet should be increased to improve stability. The narrow base results in the instability of the posture.
3. The balancing exercises like squats and lunges also lead to improvement in the stability of the body.
Thus, the narrow base decreases the stability. The correct answer is Option A.
