that's because god made us like that.
no im kidding, but it is true, but anyway, we have a nerve pathway because we do!:p
nerve my a$$ nerve
The nerve pathway travels down from the s1 spine. If the nerve root at the s1 is impinged or herniated, symptoms of sciatica can appear.
starting in the spinal cord, trace a motor pathway to the adductor muscles of the thigh. Include the spinal cord root, spinal nerve, nerve plexus, and specific peripheral nerve involved in the pathway
peripheral nerve system
The optic nerve (cranial nerve II) carries sensory information about light intensity to the brain as part of the afferent pathway in the pupillary reflex.
A contralateral motor pathway is a neutral pathway located at the opposite side of the brain. It is on the eighth nerve of the cochlear nucleus.
The internodal pathway is the specialized pathway for conducting electrical impulses between the nodes of Ranvier in myelinated nerve fibers. It allows for fast and efficient transmission of signals along the nerve fiber.

Nerve impulses are carried from the central nervous system to the effector organs (muscles or glands) by motor neurons. These motor neurons form a pathway known as the efferent pathway.
The pathway that the nerve impulse takes from your foot to your leg is called the sensory pathway. This pathway includes sensory neurons that carry signals from the foot to the spinal cord and then to the brain, where the sensation of pain is perceived and a motor response is initiated to move away from the tack.
Motor neurons
An impulse can continue to travel along a nerve pathway when there's a gap between two neurons through a process called synaptic transmission. At the gap, known as a synapse, neurotransmitters are released by the sending neuron, which then bind to receptors on the receiving neuron, triggering a new electrical signal to continue the impulse along the nerve pathway.
