A Reflex arc structure refers to the neural pathway that a nerve impulse
The neural structure typically consists of five components:
- A receptor, and independent sensory cell, or an ending of a afferent neuron , reacts to a stimulus (e.g., a stretch receptor).
- The sensory, or afferent, neuron sends a impulse through an afferent pathway to the central nervous system
- An integration center consists of 1 or more synapses in the CNS (typically the spinal cord) where the incoming information and outgoing response are integrated
- A motor, or efferent, neuron sends a impulse along an efferent pathway from the integration center to an effector cell.
- The effector cell responds to efferent impulses (for example, by contracting, if the effector may be a muscle fiber).
Because integrating center processing may occur at the extent of the spinal cord rather than requiring impulses to travel to the brain, reflex responses have a comparatively short path length and, thus, a fast reaction time compared to voluntary or conscious body movements
Spinal cord :
The medulla spinalis extends downward from the base of your brain. It's made from nerve cells and groups of nerves that carry messages between your brain and the rest of your body. medulla spinalis injuries can result from damage to the vertebrae, ligaments or disks of the vertebral column or to the spinal cord itself
