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

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
