Functions
The nervous system is responsible for everything we do. Without it we would not be able to sleep, eat, feel, smell, see, taste, move, or remember anything The nervous system controls everything that we do and it is crucial to the human body. These are the main functions of the nervous system :
Sense stimuli: the nervous system keeps track of the changes inside and outside of your body using receptors in your skin, eyes, mouth esc. In example if you touch a hot plate the receptors in your skin will send a message to your brain
Interpret the stimuli: The nervous system takes the information from the receptors and then decides on a response that would best fit the situation. For example your brain will interpret the signal of touching the hot plate and decide what needs to be done
React to things: Once your nervous system has decided on an appropriate response it will activate your muscles and glands to carry out the response. For example your brain will then activate muscles that will pull your hand away from the plate.

Parts of the brain
Cerebral Cortex: The sheet of tissue that makes of the outer layer of the brain. In controls your thought, voluntary movement, language, reasoning, and perception. It is divided into four lobes.
Frontal lobe: Associated with reasoning planning, speech, movement, emotions, and problem solving
Parietal lobe: Associated with movement, orientation, recognition, and perception of certain stimuli
Occipital lobe: In charge of visual processing
Temporal lobe: The part of the brain involved in perception and recognition of auditory stimuli, memory, and speech.
Cerebellum: Located behind the brain stem it means little brain in latin. In controls our movement, balance, and posture.
Brainstem: This is the area of the brain between the thalamus and spinal cord. It includes the pons, medulla, and reticular formation. Together they control the basic functions of life such as breathing, heart rate, and blood pressure.
Limbic system: This is found buried within the cerebrum. It contains the thalamus, hypothalamus, amygdala, and hippocampus. Together these structures are in charge of memory, emotions, and sensory processing. The hypothalumus however is incharge of your body temperature, emotions, hunger, thirst, and circadian rhythms.

Types of neurons

Sensory neurons: send impulses from the sensory receptors toward the brain and spinal cord
Motor neurons: Send impulses away from the brain and spinal cord toward muscles or glands
Interneuron: These are found inside the brain and spinal cord and they relay messages between the sensory and motor neurons. They are involved in decision-making.
Pyramidal cell: Neurons with a pyramid shaped body that are found in forebrain structures.
