Lesson 1: Functions of the Nervous System Flashcards
The nervous system, through the sensory receptors detect internal and external stimuli. It allows you to perceive changes, inside and outside of the body,
and feel sensations.
Sensory Function
refers to receiving information about the environment, either what is happening outside (ie: heat from the sun) or
inside the body (ie: heat from muscle activity)
Sensation or Stimuli
arises from sensory receptors in the skin, skeletal muscles or joints.
Somatic Sensory Information
arises from sensory receptors in the blood
vessel or internal organs.
Visceral Sensory Information
It integrates or processes sensory information by
analyzing and storing some of it and by making decisions for appropriate responses to changes.
Integrative Function
It puts perceived information together and process it. This
is activity is also known as…
Integration
The nervous system, through the motor neurons, carry information from the brain toward the spinal cord and to the different parts of the body to carry out the command. It carries out the response/s, processed by the Central Nervous System, to effector organs via the MOTOR (efferent) branch of the Peripheral Nervous System.
Motor Function
a tissue structure that responds to an efferent impulse
Effector
an impulse that travels away from the central
nervous system
Efferent impulse
