Get yours at www.boundless.com www.boundless.com/psychology The Brain and Behavior > The Nervous System Introducing the Nervous System • The nervous system is the body's main communication system that gathers, synthesizes, and uses data from the environment. • The nervous system's most basic unit is the neuron, which serves as both a sensor and communicator of internal and external stimuli. • The nervous system can be broken down into two major parts—the central nervous system and the peripheral nervous system. • The central nervous system includes the brain and spinal cord—the main data center of the body. • The peripheral nervous system includes all of the neurons that sense and communicate data to the central nervous system. The Human Nervous System View on Boundless.com • The peripheral nervous system can be further divided into the autonomic system that regulates involuntary actions, and the somatic system that controls voluntary actions.

View on Boundless.com • The brain stem includes the midbrain, pons, and medulla, and controls lower level functioning such as respiration and digestion. • The spinal cord connects the brain and the body's main receptors, and serves as a conduit for sensory input and motor output.

The Nervous System View on Boundless.com • The autonomic nervous system has two complementary parts: the sympathetic nervous system, which activates the "fight-or-flight" stress response, and the parasympathetic nervous system, which reacts with the "rest-and-digest" response after stress. • The somatic nervous system coordinates voluntary physical action.It is also responsible for our reflexes, which do not require brain input.

Get yours at www.boundless.com The Brain and Behavior Key terms • autonomic nervous system The part of the nervous system that regulates the involuntary activity of the heart, intestines, and glands, including digestion, respiration, perspiration, metabolism, and blood-pressure modulation. • brain stem The part of the brain that connects the spinal cord to the forebrain and cerebrum. • central nervous system In vertebrates, the part of the nervous system comprising the brain, brainstem and spinal cord. • cerebellum Part of the hindbrain in vertebrates.In humans it lies between the brainstem and the cerebrum, and plays an important role in sensory perception, motor output, balance and posture. • cerebrum In humans it is the largest part of the brain and is the seat of motor and sensory functions, and the higher mental functions such as consciousness, thought, reason, emotion, and memory • monosynaptic reflex Involves a single synapse, between the sensory neuron that receives the information and the motor neuron that responds. • neuron A cell of the nervous system, which conducts nerve impulses; consisting of an axon and several dendrites.Neurons are connected by synapses. • parasympathetic nervous system One of the divisions of the autonomic nervous system; located between the brain and the spinal cord; slows the heart and relaxes the muscles. • peripheral nervous system The part of the nervous system comprising a large system of nerves that are linked to the brain and spinal cord; this system is divided into the autonomic and somatic nervous systems. • polysynaptic reflex Involves at least one interneuron between the sensory and motor neurons. • somatic nervous system The part of the peripheral nervous system that transmits signals from the central nervous system to skeletal muscle and from receptors of external stimuli, thereby mediating sight, hearing, and touch. • spinal cord A thick, whitish cord of nerve tissue which is a major part of the central nervous system.It extends from the brain stem through the spine, with nerves branching off to various parts of the body.
