Soil pH affects nutrients available for plant growth. In highly acidic soil, aluminum and manganese can become more available and more toxic to plant while calcium, phosphorus, and magnesium are less available to the plant. In highly alkaline soil, phosphorus and most micronutrients become less available.
The answer your looking for is true I believe
The answer is ganglia. As indicated, they house many cell
bodies of afferent and efferent neurons.
Spinal ganglia are located in the dorsal (that contain cell bodies of afferent
neurons) and ventral roots (that house cell body
of efferent neurons) of a spinal nerve.
