Document Summary
Is specialized at one end to be highly sensitive to a particular type of stimulation (touch, light, sound, etc. ) Body/soma: contains the nucleus, mitochondria, and ribosomes, responsible for the metabolic work of the neuron, covered with synapses on its surface in many neurons, the locations of nearly all cell communication. Afferent, efferent, and intrinsic: afferent axon: transmits information inward, toward the central nervous system, efferent axon: transmits information outward, away from the central nervous system. Interneurons or intrinsic neurons are those whose dendrites and axons are completely contained within the central nervous system. Active transport: the protein-mediated process that expends energy to pump chemicals from the blood into the brain, glucose, certain hormones, amino acids, and a few vitamins are brought into the brain via active transport. 2: the blood-brain barrier is essential to health, but can pose a difficulty in allowing chemicals such as chemotherapy for brain cancer to pass the barrier.
