Organ | Function |
Cerebrum | It is a part of the brain, sub-divided into four lobes namely frontal, parietal, temporal and occipital. |
Cerebellum | This part of the brain is mainly involved in motor control. Language, concentration, pleasure responses, etc. are some of the other areas of functioning of the cerebellum. |
Limbic System | The limbic system controls our emotional responses and also helps in memorizing and learning. |
Brain Stem | The brain stem performs different functions like sensing the vibrations, recognizing fine touch, pain, crude touch, itching, etc. This part of the brain is also associated with proper functioning of the respiratory and cardiac systems. |
Hind Brain | Coordination of body movements and homeostasis are both carried out by the hind brain. The hind brain is formed of the medulla, cerebellum and pons. |
Basal Ganglia | Body balance and movements are controlled by the basal ganglia. |
Medulla Oblangata | This part of the brain controls breathing, blood pressure and heart rate. |
Spinal Cord | The spinal cord plays an important role in connecting the peripheral nervous system with the brain. Here are the different functions performed by the spinal cord. |
Somatic Nervous System | This nervous system controls all the voluntary movements of our body by means of skeletal muscles; reflex arc is an exception to it. There are 3 kinds of somatic nerves described below. |
Spinal Nerves | These nerves carry information obtained from the sensory organs to the spinal cord. |
Association Nerves | They bring about the integration of sensory input and motor output. |
Cranial Nerves | These are the nerves of the somatic system which transfer the information entering into and emerging from the brain stem. |
Autonomic Nervous System | This nervous system is also known as visceral or involuntary nervous system. Digestion, perspiration, respiration, urination, pupillary dilation, etc. are the processes controlled by this nervous system. |
Enteric Nervous System | It is a sub-division of the autonomic nervous system. The enteric nervous system (ENS) controls the gastro-intestinal system. Although the ENS is a part of the autonomic nervous system, it is also capable of functioning independently. |
