sense organs

Detailed explanation-1: -Sensory neurons carry impulses from the receptors in the sense organs to the CNS, while the association or connection neurons carry impulses from the sensory to the motor neurons. The motor neurons carry impulses from the CNS to the effectors.
Detailed explanation-2: -Afferent, or sensory, neurons carry impulses from peripheral sense receptors to the CNS. They usually have long dendrites and relatively short axons. Efferent, or motor, neurons transmit impulses from the CNS to effector organs such as muscles and glands.
Detailed explanation-3: -A sensory neuron transmits impulses from a receptor, such as those in the eye or ear, to a more central location in the nervous system, such as the spinal cord or brain.
Detailed explanation-4: -Sensory neurons transmit nerve impulses from sense organs (eyes, ears, nose, tongue and touch) to the brain. They also carry nerve impulses to the brain and spinal cord. Motor neurons transmit nerve impulses from the brain and spinal cord to a specific area of the body.
Detailed explanation-5: -A sensory neuron picks up stimuli from the internal or external environment and converts each stimulus into a nerve impulse. An interneuron is a neuron that carries nerve impulses from one neuron to another. A motor neuron sends an impulse to a muscle or gland, and the muscle or gland then reacts in response.
