Basic organization of the nervous system: The major components and functions of the nervous system Central Nervous System The central nervous system (CNS) consists of the brain and spinal cord and is responsible for integrating, processing, and coordinating sensory data and motor commands Information processing includes the integration and distribution of information in the CNS Peripheral Nervous System The peripheral nervous system (PNS) includes all the neural tissue outside the CNS The motor division of the PNS carries motor commands from the CNS to peripheral tissues and systems. Includes The sensory division of the PNS brings information to the CNS from receptors in peripheral tissues and organs. Somatic sensory receptors provide position, touch, pressure, pain, and temperature sensations. The somatic nervous system (SNS) controls skeletal muscle contractions. The autonomic nervous system (ANS) provides automatic regulation of smooth muscle, cardiac muscle. glands, and adipose tissue. Special sensory receptors provide sensations of smell, taste, vision, balance, and hearing. Skeletal muscle Smooth muscle Cardiac muscle Glands Adipose tissue Start Visceral sensory receptors monitor internal organs. 1 Receptors are sensory structures that detect changes in the internal or external environment. Effectors are target organs whose activities change in response to neural commands. 2011 Peanon
