⚡Neurons are also called nerve cells. ⚡
߷There are three types of neurons.
• Sensory Neurons.
• Motor Neurons.
• Interneurons.
⚝ Brain needs all these types of neurons to communicate effectively with the rest of the body.
⚡Sensory neurons respond to stimuli such as touch, sound or light that affect the cells of the sensory organs and they send signals to the spinal cord.⚡
⚡Motor neurons receive signals from the brain and spinal cord to control muscle contractions.⚡
