2 The Nervous SystemThe central nervous system (CNS): brain and the spinal cord.Peripheral nervous system (PNS): nerves.Motor neurons: deliver the instructions from the brain to the rest of your body.The spinal cord: carries messages to and from the brain.
3 The BrainThree main parts of brain: the forebrain, midbrain, and hindbrain.Forebrain: cerebrum, thalamus, and hypothalamus (part of the limbic system).Midbrain: tectum and tegmentum.Hindbrain: cerebellum, pons and medulla.
4 The CerebrumLargest part of the human brain, associated with higher brain function such as thought and action.Divided into four sections, called "lobes": the frontal lobe (reasoning, planning, parts of speech, movement, emotions, and problem solving); parietal lobe (movement, orientation, recognition, perception of stimuli); occipital lobe (visual processing); and temporal lobe (perception and recognition of auditory stimuli, memory, and speech).Divided into two halves: left hemisphere = logic and right hemisphere= creativity.
5 The CerebellumRegulates and coordinates movement, posture, and balance.“Little brain.”Two hemispheres.
6 Limbic System ”Emotional brain" is found buried within the cerebrum. Contains the thalamus (sensory and motor functions); hypothalamus (emotion, thirst, hunger, circadian rhythms); amygdala (memory and emotion); and hippocampus (learning and memory).
7 Brain StemResponsible for basic vital life functions such as breathing, heartbeat, and blood pressure.The brain stem is made of the midbrain (vision, hearing, eye movement and bodily movement); pons (motor control and sensory analysis); and medulla (maintaining vital bodily functions such as breathing).
