Central Nervous System
The central nervous system develops from an embryonic neural tube (the tube eventually becomes the brain and spinal cord). The nerve tissues extending from the CNS controls the activities of the body. The CNS integrates sensory information and responds accordingly.
Peripheral Nervous System
The peripheral nervous system is the part of the nervous system that consists of nerves outside the brain and spinal cord. Two cells are present in the PNS: sensory nervous cells and motor nervous cells. Both cells carry information The peripheral nervous system is also divided into four parts: the Sensory Nervous System, Motor Nervous System, Somatic Nervous System, and Autonomic Nervous System,
SECTIONS OF THE BRAIN
The Lobes
The Frontal Lobe | The frontal lobe is the front portion of the brain and is responsible for planning, organizing, problem solving, selective attention, and personality. It is also responsible for behavior, emotions, and speech (Broca's Area). |
The Temporal Lobe | The temporal lobe is responsible for auditory association, language association (Wennicke's Area). It receives information from such as sounds and speech from the ears. |
The Occipital Lobe | The occipital lobe is responsible for vision and visual association. Information is received through our eyes. |
The Parietal Lobe | The parietal lobe aids in reading, taste (gustatory area). It is associated with the visual association area and the primary sensory area. |
Cerebellum
The cerebellum is located in the bottom portion of the brain.. Its main responsibility is balance and the coordination of the muscles and the body.
The Brain Stem
The brain stem provides basic survival functions. It is responsible for the regulation of heart rate, breathing, sleeping, and eating. There are three regions of the brain stem: the medulla oblongata, pons, and midbrain.
