in the nervous system. A second factor is infection we are familiar with the idea of bacteria or viruses causing physical illness such as flu. It seems though that infection can also give a rise to mental illness. Flu has been linked to schizophrenia. Recent research shows that schizophrenia cases have been linked with exposure to the flu virus in the womb during the first trimester. The third factor is biochemistry. Neurotransmitters are thought to be out of balance in the nervous system of individuals

with a sensory experience. This begins when the sensory receptors receive energy from a particular stimulus‚ which trigger receptor cells. The physical energy is converted into electrochemicals‚ then passes along sensory nerves‚ to the central nervous system where the brain receives the energy as a detailed message. However‚ not all physical energy produces a sensation. A minimum intensity‚ termed absolute threshold‚ must be achieved in order to produce a sensation. Perception takes place when the

considered a transmitter. These four steps include the synthesis of a transmitter substance‚ the storage and release of the substance‚ its interaction with a receptor in the membrane‚ and the removal of the transmitter form the synaptic cleft. The nervous system makes use of two types of neurotransmitters: small-molecule transmitters (acetylcholine‚ amines and A.A) and neuroactive transmitters(peptides) 2. Neurons have developed a sophisticated ability to regulate the synthesis‚ storage‚ release‚ and

Sensory neurons send information from the body’s tissues and sensory organs inward to the brain and spinal cord‚ which process the information. Motor neurons carry outgoing information from the central nervous system to the body’s tissues.Interneurons in the central nervous system communicate internally and intervene between the sensory inputs and the motor outputs. The axons of some neurons are encased by a myelin sheath‚ which helps speed their impulses. A neural impulse‚ or action
