Autonomics I Flashcards
Neurotrans for Parasymp: cardiac and smooth muscle, gland cells, nerve terminals
Ach, M
Neurotrans for for symp sweat glands
ACh, M
Neurotrans for symp: cardiac and smooth muscle, gland cells, nerve terminals
NE, alpha, beta
Neurotrans for Symp: renal vascular smooth muscle
D
Neurotrans for somatic skeletal muscle
ACh, N
Sympathetic Nervous System: Pre-ganglionic
Cell bodies are
thoracolumbar
Sympathetic Nervous System: Pre-ganglionic
axons extend to
para-and pre- vertebral ganglia
Sympathetic Nervous System: Pre-ganglionic
axon terminals synapse onto
sympathetic post-ganglionic neurons
Sympathetic Nervous System: Post-ganglionic
cell bodies are in the
para- and pre-vertebral ganglia
Sympathetic Nervous System: Post-ganglionic
axons/fibers extend to
effector tissues/organs
Sympathetic Nervous System: Post-ganglionic
also innervate
adrenal medulla
Parasympathetic Nervous System: Pre-ganglionic
cell bodies are in
craniosacral
Parasympathetic Nervous System: Pre-ganglionic
axons extend to ganglia located
near or in effector tissues/organs
Parasympathetic Nervous System: Post-ganglionic
cell bodies are located
near or on effecto tissues
ACh used by both the symp and parasymp pre ganglionic fibers
Pre-ganglionic
ACh acts through nicotinic receptors located on post-ganglioic fibers
Pre-ganglionic
Drugs that alter ACh levels affect BOTH the sym and para sym systems
Pre-ganglionic
Use DA, NE, EPI
Post-ganglionic sympathetic
Most use NE
Post-ganglionic sympathetic
The adrenal gland releases both NE and EPI
Post-ganglionic sympathetic
NE and EPI act on alpha and beta receptors
Post-ganglionic sympathetic
DA activates D1 (aswell as alpha and beta)
Post-ganglionic sympathetic
Uses ACh
Post-ganglionic parasympathetic
ACh acts on muscarinic receptors in most effector tissues, or nicotinic in somatic muscles
Post-ganglionic parasympathetic
