Autonomic Pharmacology 1 Flashcards
How can the nervous system be divided?
Central Nervous System
Peripheral Nervous System
How can the Peripheral System be divided?
Somatic Efferent
Enteric Nervous System
Autonomic Nervous System
Somatic/ Visceral Afferent
What does the Somatic Afferent Nervous System do?
Nerves in the:
Skin
Joints
Muscle
Send information to the Central Nervous System
What does the Somatic Efferent Nervous System do?
Includes nerves that lead the Central Nervous System and the Enervate Muscle
Produces Voluntary Contractions
What is the Enteric Nervous System?
Built into the GI tract
Includes the Myentric Plexus and the Submucosal Plexus
What are the two plexuses used in the Enteric Nervous System ?
Myentric Plexus
Submucosal Plexus
What are the two divisions of the Autonomic Nervous System?
Sympathetic Division
Parasympathetic Division
What is the autonomic nervous system generally responsible for?
Responsible for carrying the output from the CNS to the body
- WITH THE EXCEPTION OF SKELETAL MUSCLE
What are the main functions of the Autonomic Nervous System?
Contraction/Relaxation of Vascular Muscle Contraction/Relaxation of Smooth Muscle All Exocrine section (Duct glands) Some Endocrine glands (Ductless glands) The Heartbeat Aspects of Metabolism
(Generally unconscious, controls)
What is a Ganglion?
A Ganglion is a collection of Nerve Cells bodies that lies outsider of the CNS
What part of the Autonomic Nervous System symbolises “Fight, Flight and Fright” ?
Sympathetic System
What type of neurone is the Preganglionic Neurone in the Sympathetic Division?
Cholinergic
- Uses Acetylcholine (ACh)
What type of neurone is the Postganglionic Neurone in the Sympathetic Division?
Adrenergic
- Uses Noradrenaline (NA)
Between what parts of the spine supplies the Sympathetic Outflow?
T1 Spinal Nerve -> L2 Spinal Nerve
Thoraco-lumbar Outflow
How is the Adrenal Gland innervated?
By a Pre-ganglionic neurone
