Presentation transcript:

Functions of the Nervous System Sensory input — gathering information –Sight, Touch, Hearing, Tasting & smelling Tasting & smelling –To monitor changes occurring inside and outside the body –Stimuli causes a reaction by the body Sensory Integration – how we use Sensory Integration – how we use information provided by all the sensations coming from within the body and from the external environment

Functions of the Nervous System Motor output –A response to integrated stimuli –The response activates muscles or glands to perform a specific action Example: Timing and muscle coordination needed to slide into second base gracefully.

Functions of the Nervous System

Nervous System Organization Central nervous system –Brain –Spinal cord Peripheral nervous system –Nerves outside the brain and spinal cord and spinal cord

Functions of the Peripheral Nervous System Afferent  Sensory division – –Nerve fibers that carry information to the central nervous system – –Info sent to brain for processing Efferent  Motor division – –Nerve fibers that carry impulses away from the central nervous system – –Info sent away from brain to muscles and glands

Motor Division of Peripheral Nervous System Efferent  Motor division –Two subdivisions Somatic nervous system = voluntary - You actively control these reactions - Skeletal muscles Autonomic nervous system = involuntary - You do NOT control these reactions - You do NOT control these reactions - Example: sneezing to get rid of foreign substance in - Example: sneezing to get rid of foreign substance in nasal passage nasal passage

Autonomic Involuntary Nervous System Sympathetic Branch –fight-or-flight” –controls “fight-or-flight” response - brain gives off messages which triggers the release of adrenaline it uses energy, your blood pressure increases, your heart beats faster, and digestion slows down. The autonomic nervous system acts to maintain normal internal functions. It controls the involuntary functions of organs like, digestion, breathing, metabolism or blood pressure. Consists of two branches.

Autonomic Involuntary Nervous System Parasympathetic Branch – –lowers heart rate and blood pressure, diverts blood back to skin and the digestive tract, contracts pupils, constricts bronchiole tubes in lungs, resumes digestion. The autonomic nervous system acts to maintain normal internal functions. It controls the involuntary functions of organs like, digestion, breathing, metabolism or blood pressure. Consists of two branches.

The sympathetic system undoes the parasymphathetic effects on the body. After a stressful event, the parasymphathetic system returns the body’s levels back to a homeostatic balance. Homeostasis is the ability to maintain a constant internal environment in response to environmental changes.
