The minimal number of neurons involved starting with the receptor of a sensory pathway to reach the effector of a motor pathway is 3.

1. Sensory neuron: This is the first neuron in the pathway. It carries signals from receptors in the skin, muscles, bones, and joints to the spinal cord.

2. Interneuron: This is the second neuron in the pathway. It is located within the spinal cord and it processes the information received from the sensory neuron and then activates a motor neuron.

3. Motor neuron: This is the third and final neuron in the pathway. It carries signals from the spinal cord to the muscles (effectors).

So, none of the options provided (5, 6, 7, 8) are correct. The correct answer is 3.
