AP PSYCHOLOGY

Detailed explanation-1: -This is due to responsiveness to stimuli. When we touch a hot object the sense organs feel the temperature and the hand is withdrawn. The stimulus is carried to the brain by the sensory neuron while it is carried back to effector organs by motor neurons.

Detailed explanation-2: -For example, if you touch a hot stove, the nerves in your skin shoot a message of pain to your brain. The brain then sends a message back telling the muscles in your hand to pull away. Luckily, this neurological relay race happens in an instant.

Detailed explanation-3: -Impulses from the sensory cortex are conducted over interneurons to the prefrontal cortex of the cerebrum to be “recorded” as memories that associate the sight of a hot stove with pain. These memories cause you to be more careful when you are near a hot stove.

Detailed explanation-4: -Sensory neurons are the nerve cells that are activated by sensory input from the environment-for example, when you touch a hot surface with your fingertips, the sensory neurons will be the ones firing and sending off signals to the rest of the nervous system about the information they have received.

Detailed explanation-5: -The sensory neurons have nerve endings in the skin which carry the impulse, created due to heat, to the spinal cord. The relay neuron transmits it to the effector/motor neuron which makes the muscles move and hand is taken back.
