ANATOMY

Detailed explanation-1: -When neurons communicate, the neurotransmitters from one neuron are released, cross the synapse, and attach themselves to special molecules in the next neuron called receptors. Receptors receive and process the message, then send it on to the next neuron.

Detailed explanation-2: -The brainstem takes in, sends out, and coordinates the brain’s messages. It also controls many of the body’s automatic functions, like breathing, heart rate, blood pressure, swallowing, digestion, and blinking.

Detailed explanation-3: -The spinal cord conducts sensory information (information from the body) from the peripheral nervous system to the brain. After processing its many sensory inputs, the brain initiates motor outputs (coordinated mechanical responses) that are appropriate to the sensory input it receives.

Detailed explanation-4: -Your nervous system uses specialized cells called neurons to send signals, or messages, all over your body. These electrical signals travel between your brain, skin, organs, glands and muscles. The messages help you move your limbs and feel sensations, such as pain.
