PPT-Nervous Impulse

Action Potential The nature of Nerve Impulse Nerve impulses are caused by the movement of electrically charged ions sodium potassium These messages are caused by a potential or a difference between the inside and outside of the membrane of the neuron . Functions of the Nervous System. Sensory input – gathering information. To monitor changes occurring inside and outside the body. Changes = stimuli. Integration. To process and interpret sensory input and decide if action is needed. Mr. E Murphy. Strange fact. A newborn baby's brain grows almost 3 times during the course of its first year. . Objectives.

Neuron. is defined as the structural and functional unit of the nervous system. It is otherwise called nerve cell. Neuron is like any other cell in the body having nucleus and all the organelles in the cytoplasm. However, it is different from other cells by two ways: . Follow-Me – . iQuiz. Q. True or False.
