Reflex arcs have evolved as efficient ways of functioning in several emergency situations. reflex [re´fleks] a reflected action or movement; the sum total of any particular automatic response mediated by the nervous system. A reflex is built into the nervous system and does not need the intervention of conscious thought to take effect. The knee jerk is an example of the simplest type of reflex. When the knee is tapped, the nerve that 2021-04-11 Reflex Arcs •In a knee-jerk reflex arc the sensory neuron directly connects to the motor neuron in the spinal cord.

2020-12-07 Many situations require quick reactions. There is no time to think and act. In such cases, reflex actions are important. The reflex arcs are formed in the spinal cord itself, hence there is no need for actual thought process to take place. Reflex arcs have evolved as efficient ways of functioning in several emergency situations. reflex [re´fleks] a reflected action or movement; the sum total of any particular automatic response mediated by the nervous system.

A reflex arc is the neural pathway that mediates a reflex action. In higher animals, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This characteristic allows reflex actions to occur relatively quickly by activating spinal motor neurons without the delay of routing signals through the brain, although the brain will receive sensory input while the
