You accidentally step on a nail. Describe all neural processes you can think of involved leading up to your regaining your balance. You can underline/highlight each new item, eg. the "withdrawal reflex occurs;" not to lose points.

Reflex arc in case of step on nail

The sensory receptors in the region of foot will get activated and this will set signal to the afferent nerve that will cause the signal to reach the centre in this case it is spinal cord and this sent the response through the afferent Nerve and this will lead to the response in the area . This will be the contraction of the muscle if the legs and talking it away

Neural process in neuromuscular junction will release the Acetylcholine and will stimulate for the contraction if the muscle

The pain receptors in free nerve ending will take signal to the sensory cortex through the nerves and nerve ganglion . This will lead to pain perception in individual.

The vestibular system sents signal to the Brian and cause the maintain the balance of head and the fluid in the semicircular canals.

Visual stimuli to brain lead to help in maintaining balance which move through optic nerve to brain
