Document Summary
Controls and integrates all body activities (along with the endocrine system) Three basic functions: sensory sensing changes with sensory receptors, integration interpreting and remembering those changes, motor reacting to those changes with effectors (muscular contractions; glandular secretions) The nervous system is one of the smallest and yet the most complex of the 11 body systems. It is a highly organized network of 2 cell types contains billions of neurons and more neuroglia. The structures that compose the nervous system include: the brain, cranial nerves and their branches, the spinal cord, spinal nerves and their branches, ganglia, enteric plexuses, and sensory receptors. Includes perception (conscious awareness of sensory stimuli occurs in brain). Interneurons (neurons that interconnect with other neurons) with axons that extend for a short distance will contact nearby neurons and in the brain/spinal cord to set up the circuit boards of the cns. Consists of sensory neurons (somatic sensory neurons) that convey information to the.
