NEURAL FUNCTION
FUNCTIONS OF SYMPATHETIC NERVOUS SYSTEM
DECREASES SALIVATION
INCREASES HEART RATE
OPENS ( DILATES ) THE PUPILS TO ALLOW LIGHT IN
INCREASES FLOW OF AIR IN THE LUNGS AND INHIBITS DIGESTIVE
TRACT ( URINARY BLADDER, PANCREAS, STOMACH AND INTESTINE )
INCREASE BLOOD FLOW
FUNCTIUON OF PARASYMPATHETIC NERVOUS SYSTEM
CLOSEST/CONSTRICT THE PUPIL OF THE EYES
INCREASES SALIVATION
DECREASES HEART RATE
DECREASES FLOW OF AIR IN THE LUNGS AND ACTIVATES THE DIGESTIVE
TRACT
DECREASE BLOOD FLOW
NEURAL FUNCTIONING
The basic pattern of neural activity is the stimulus- response (S-R) sequence.
The S-R sequence is a follows :
A stimulus strikes a receptor
The receptor stimulates the dendrites of sensory neuron, making a nerve
impulse travel to the afferent or incoming fiber to the endbrush.
The impulse crosses the synaphic connection or junction and stimulates the
dendrites of a connector neuron in the spinal cord.
The impulse passes another synapse from theconnector neuron to
dendrites of an efferent or outgoing neutron.
The impulse passes along the efferent fiber is endbrush.
