FINAL TEST WITH ACTUAL EXAM TIPS




Nervous System The master controlling and communicating system of
the body
1. sensory input

Nervous System 2. integration

Functions: 3. motor output

Sensory Input Monitoring stimuli that gathers information
Integration Interpretation of the sensory Input
Motor Output Response to stimuli of sensory information
Organization of the CNS and PNS
Nervous System
Central Nervous brain and spinal cord
System consists of - Integration and Command Center
Peripheral Nervous Paired spinal and cranial nerves
System consists of - Carries messages to & from spinal cord & brain
Two Functional 1. Sensory (afferent) division
Divisions of the PNS 2. Motor (efferent) division



Sensory (Afferent) Carries impulses from receptors to the CNS
- Keeps brain informed about conditions
Division of PNS
inside & outside of the body
Motor (Efferent) Transmits impulses from the CNS to effector organs
Division
Motor (Efferent) 1. Somatic (Voluntary) Nervous System
Division of PNS: Two 2. Autonomic (Involuntary) Nervous System


Main Parts

Somatic (Voluntary) Conscious control of skeletal muscles
Nervous System
Autonomic Regulates smooth muscle, cardiac muscle, & glands
(Involuntary) - Made up of sympathetic and parasympathetic
systems
Nervous
System

Sympathetic Nervous Stress caused
System - "Fight or Flight"
Parasympathetic Calming portion of Autonomic Nervous System
Nervous System - "Rest and Digest"
