GENERAL HISTOLOGY

Detailed explanation-1: -The spinal cord gives the response instead of taking it to the brain. This response reaches the effector through the motor/efferent neuron which stimulates the effector muscles or organs. Finally, the response is given by the effector organ.

Detailed explanation-2: -The reflex arc is a special type of neural circuit that begins with a sensory neuron at a receptor (e.g., a pain receptor in the fingertip) and ends with a motor neuron at an effector (e.g., a skeletal muscle).

Detailed explanation-3: -The primary components of the reflex arc are the sensory neurons (or receptors) that receive stimulation and in turn connect to other nerve cells that activate muscle cells (or effectors), which perform the reflex action.

Detailed explanation-4: -An effector is a muscle or gland that receives the impulse from the motor neuron. In somatic reflexes, the effector is skeletal muscle.

Detailed explanation-5: -So the reflex arc consists of these five steps in order-sensor, sensory neuron, control center, motor neuron, and muscle.
