Autonomic nervous system WK6 L1 Flashcards
WHAT IS THE AUTONOMIC NERVOUS SYSTEM?
A SYSTEM THAT INNERVATES ORGANS WHOS FUNCTION IS NOT USUALLY UNDER VOLUNTARY CONTROL
WHATS INCLUDED IN THE AUTONOMIC NERVOUS SYSTE,?
MOST VISCERAL ORGANS - BLOOD VESSELS - SMOOTH MUSCLES - GLANDS
WHAT DOES THE AUTONOMIC NERVOUS SYSTEM DO?
REGULATES BODY SYSTEMS - REGULATES UNCOSIOUS PROCESSES THAT MAINTAINS HOMEOSTASIS

2
WHAT CHEMICAL DOES THE SOMATIC NERVOUS SYSTEM RELEASE?
ACETOLCOLENE
WHAT CHEMICAL DOES THE AUTONOMIC NERVOUS SYSTEM RELEASE AT THE PRE GANGLIONIC NEURONS?

WHICH AUTONOMIC NERVOUS SYSTEM RELEASES NOREPINEPHRINE AT THE POST GANGLIONIC NEURONS?
SYMPATHETIC NERVOUS SYSTEM
WHAT IS THE 1ST MOTOR NEURON OF AUTONOMIC NERVUS SYSTEM?
PRE GANGLIONIC
WHAT IS THE 2ND MOTOR NEURON OF AUTONOMIC NERVOUS SYSTEM
POST GANGLIONIC
WHICH MOTOR NEURONS FROM THE AUTONOMIC NERVOUS SYSTEM COME FROM THE BRAIN OR SPINAL CHORD?
PRE GANGLIONIC
WHICH MOTOR NEURONS FROM AUTONOMIC NERVOUS SYSTEM GO TO THE EFFECTOR?
POST GANGLIONIC
WHAT DOES THE SOMATIC NERVOUS SYSTEM INCLUDE?
SKELETAL MUSCLE
WHAT ARE THE DIVISIONS OF THE AUTONOMIC NERVOUS SYSTEM?
SYMPATHETIC - PARASYMPATHETIC
WHAT DOES THE SYMPATHETIC NERVOUS SYSTEM DO?
MOBILISES BODY DURING ACTIVITY - FIGHT OR FLIGHT
WHAT DOES THE PARASYMPATHETIC NERVOUS SYSTEM DO?
PERFORMS MAINTENANCE ATIVITIES - CONSERVES BODYS ENERGY - REST AND DIGEST
WHAT IS CRANIOSACRAL?
OUTFLOW OF PARASYMPATHETIC NERVOUS SYSTEM
WHAT IS THORASOLUMBAR?
OUTFLOW OF SYMPATHETIC NERVOUS SYSTEM
WHAT ARE VISCERAL REFLEXES?
UNCONCIOUS AUTOMATIC RESPONSES OF STIMULATION TO GLANDS, CARDIAC MUCLES, OR SOMOOTH MUSCLE
HOW DO VISECRAL REFLEXES TRAVEL?
RECEPTORS - SENSORY NERUONS - INTER NEURONS - MOTOR NEURONS - EFFECTOR
WHICH SYSTEM ARE THE ADRENAL GLANDS PART OF?
SYMPATHETIC NERVOUS SYSTEM
WHAT ARE THE PARTS OF ADRENAL GLANDS?
CORTEX - MEDULLA
WHAT IS THE MEDULLA OF ADRENAL GLANDS?
MODIFIED SYMPATHETIC GANGLION STIMULATED BY PRE GANGLIONIC SYMPATHETIC NEURONS
WHAT DO THE ADREANAL GLANDS DO?
SECRETES HORMONES INTO THE BLOOD
WHCH HORMONES DO THE ADRENAL GLANDS SECRETE?
CATECHOLAMINES - EPINEPHRINE - NOREPINEPHRINE
WHICH CRANAL NERVES ARE IN THE PARASYMPATHETIC NERVOUS SYSTEM?
CN III 3 - OCCULOMOTOR
CN VII 7 - FACIAL NERVER
CN IX 9 - GLOSSOPHARANGYEAL NERVE
CN X 10 - VAGUS NERVE
WHAT ARE THE FUNCTIONS OF THE SYMPATHETIC NERVOUS SYSTEM?
INCREASE HEART RATE - INCREASE AIRFLOW - REDIRECT BLOOD - INHIBIT DIGESTIVE SYSTEM - INCREASE BLOOD GLUCOSE CONCENTRATION - INCREASE MOTABILISIM
WHAT ARE THE FUNCTIONS OF THE PARASYMPATHETIC NERVOUS SYSTEM?
DECREASE HEART RATE - DECREASE AIRFLOW - INCREASED GLANDULAR SECRETION - INCREASED DIGESTIVE SYSTEM - PENILE ERECTION
WHAT ARE THE TWO MAJOR CATEGORIES OF RECEPTORS?
ADRENERGIC - CHOLINERGIC
WHAT ARE THE TWO TYPES OF ADRENERGIC RECEPTORS?
ALPHA - BETA
WHAT ARE THE TWO TYPES OF CHOLINERGIC RECEPTORS?
NICOTINIC - MUSCARINIC
WHAT RECEPTOR IS FOUND ON THE POST GANGLIONIC NEURONS IN THE AUTONOMIC NERVOUS SYSTEM?
NICOTENIC RECEPTORS
WHAT RECEPTOR IS FOUND ON THE EFFECTORS IN THE AUTONOMIC NERVOUS SYSTEM?
MUSCARINIC RECEPTORS
