Document Summary
The neuron specialized cell a. receives, processes and/or transmits information to other cells in the body: 200 different types of neurons, 100 billion 1 trillion in the brain, parts of a neuron c. i. Dendrites branched fibers, receive incoming signals and stimulation from sense receptors/ neurons c. ii. Soma cell body, contains nucleus and cytoplasm essential for cell life. Integrates information received from dendrites, passes it to the axon c. iii. Axon a single, extended fiber that conducts information along its length to swollen, bulblike structures terminal buttons. c. iv. Sensory neurons carry messages from sense receptors towards central nervous system e. ii. Motor neurons carry messages away from central nervous system toward muscles and glands effectors. e. iii. Interneurons most of the neurons in the brain, relay messages from sensory neurons to other interneurons to motor neurons. e. iv. Glia not neurons 5-10 times as many of these cells than neurons in the brain. Hold neurons in place, and other important functions e. iv. 1.
