Term
\f0\fs24 \cf0 Sympathetic system effect on heart
Definition
rate and force of cardiac muscle increase resulting in increase cardiac output of blood\
Term
\cf0 Sympathetic system effect lungs
Definition
smooth muscle in wall of bronchioles becomes relaxed tube dilated allow more air to enter lungs\
Term
Sympathetic system effect on gut
Definition
rate of contraction of smooth muscle wall of digestive tract decrease rate of peristalsis (digestion)\
Term
Sympathetic system effect sweat glands
Definition
sweat gland stimulated increased rate of nervous perspiration\
Term
Sympathetic system effect adrenal glands
Definition
adrenal glands stimulated increase rate of secretion of hormone adrenaline\
Term
parasympathetic system effect heart
Definition
rate of contraction decrease, decrease in blood output\
Term
parasympathetic system lung
Definition
smooth muscle wall contract and decrease air into lungs\
Term
parasympathetic system digestive tract
Definition
Rate of contraction of smooth muscle in wall of digestive track increase, increase in rate of peristalsis.\
Term
Central Nerves system
Definition
Is composed of brain and spinal cord motor neurones carry impulses from CNS to muscles and glands\
Term
Peripheral nervous system
Definition
Is made up of sensory neurones carrying impulses from receptor in CNS and consist of somatic and automatic nervous system.\
Term
Somatic nervous system (PNS)
Definition
Deals with functions under conscious control walking speaking\
Term
Automatic nerve system (PNS)
Definition
Deals with automatic functions e.g. heart rate. Is divided into sympathetic and parasympathetic\
Term
peripheral nervous system sensory neurone
Definition
carries impulses from receptor to Central nervous system
Term
perpheral nervous system motor neurone
Definition
carries impulses from central nervous system to muscle and glands \
Term
Antagonistic
Definition
Have opposite effects e.g. sympathetic and parasympathetic\
Term
Nervous system
Definition
made up of central nervous system and peripheral\
