Term
WHAT TYPE OF RECEPTOR IS M1, M2, M3?
Definition
M1 IS A Gq, M2 IS A Gi, M3 IS A Gq.
Term
WHAT IS GOING TO HAPPEN TO A M2 RECEPTOR WHEN STIMULATED?
Definition
IT IS LINKED TO A Gi PROTEIN WHICH IS GOING TO INCRASE K CONDUCTANCE NOT THROUGH ACH RECEPTOR BUT THROUGH A LEAK CHANNEL OR A TYPE OF K CHANNEL HERE. THAT IS GOING TO INCREASE THE LIKELIHOOD OF HYPERPOLARIZING THE CELL AT THE SAME TIME I'M REDUCING THE AMOUNT OF Ca coming in from the ECF INSIDE THE CELL.
Term
WHAT HAPPENS WHEN M3 IS STIMULATED?
Definition
SMOOTH MUSCLE CONTRACTION
Term
THE PNS HAS TO DO WITH SLUDGE. WHAT DOES THAT MEAN?
Definition
SALIVATION, LACRIMATION, URINATION, DEFECATION, GASTRIC MOTILITY AND SECRETIONS, EMESIS/ERCETION. EMESIS AND ERECTION IS PARASYMPATHETICALLY MEDIATED. EJACULATION IS SYMPATHETICALLY MEDIATED.
Term
WHAT ARE MIXED NERVES?
Definition
CRANIAL NERVES THAT HAVE BOTH SENSORY AND MOTOR FUNCTION
Term
WHAT IS CN 3 GANGLIA CALLED?
Definition
THE OCULOMOTOR, THE PNS FIBERS THAT WE FIND IN THE OM NERVE WILL TERMINATE IN THE CILIARY GANGLIA. POSTSYNAPTIC FIBER FROM THERE WILL THEN PROCEED TO THE CILIARY MUSCLES OF THE EYE AND THE IRIS TO FOCUS.
Term
WHERE DOES CN 7 TERMINATE AT PRESYNAPTICALLY?
Definition
CN 7 TERMINATES AT THE PTERYGOPALATINE GANGLIA THAT GOES TO THE LACRIMAL GLAND. IT ALSO TERMINATES AT THE SUBMANDIBULAR GANGLIA WHICH GOES TO THE SUBLINGUAL AND THE SUBMANDIBULAR SALIVARY GLANDS.
Term
WHERE DOES CN 9 TERMINATE AT PRESYNAPTICALLY?
Definition
SYNAPSES AT THE OTIC GANGLIA AND THE OTIC GANGLIA INNERVATES THE PAROTID SALIVARY GLANDS.
Term
WHAT 2 THINGS DOESN'T THE VAGUS NERVE INNERVATE?
Definition
URINATION AND DEFECATION
Term
WHERE ARE THE GANGLIA FOR THE VAGUS?
Definition
IN THE WALL OF THE ORGAN ITSELF.
Term
WHERE ARE THE CELL BODIES FOR THE SACRAL PART OF THE PNS GOING TO BE AT?
Definition
CONUS MEDULARIS WHICH IS AROUND L1-L3
Term
FROM THE CONUS MEDULARIS WHERE WILL THE FIBERS OF THE PNS EXTEND TO?
Definition
THROUGH THE CAUDA EQUINA AND EXIT THROUGH THE SACRAL FORAMINA. THERE ARE NO CELL BODIES IN THE CAUDA EQUINA. THE CAUDA EQUINA IS THE AXON. THE OUTFLOW IS OUT OF THE VERTEBRAL CANAL AT THE SACRAL FORAMINA.
Term
WHERE ARE THE CELL BODIES OF THE PREGANGLIONIC FIBERS OF THE PNS THAT INNERVATE THE HEART FOUND AT?
Definition
IN THE BRAINSTEM.
Term
WHERE ARE THE CELL BODIES OF THE PREGANGLIONIC FIBERS OF THE PNS FOUND AT?
Definition
IN THE CONUS MEDULLARIS, BUT THEY EXIT AT THE SACRAL FORAMINA.
Term
NAME THE 4 PREVERTEBRA GANGLIA OF THE SNS
Definition
1) CELIAC GANGLIA, 2) AORTICORENAL GANGLIA, 3) SUPERIOR MESENTERIC, 4) INFERIOR MESENTERIC
Term
WHAT DOES THE AORTICORENAL GANGLIA INNERVATE?
Definition
THE KIDNEYS
Term
DURING SNS HOW DOES THE KIDNEYS RESPOND TO THE STIMULATION?
Definition
THE VESSELS OF THE KINDEYS CONTRICT. I DONT WANT TO BLOW MY GLOMERULI APART WITH SO MUCH PRESSURE AND SO MUCH FLUID COMING INTO IT SO I HAVE TO LIMIT MY AMOUNT OF FLUID THAT'S GOING TO ENTER THE GLOMERULUS.
Term
LIKE THE CELIAC AND MESENTERIC NERVES HOW DOES INNERVATION OF THE SNS GET TO THE KIDNEYS?
Definition
THE AORTICORENAL GANGLIA POSTSYNAPTCALLY FROM THE PREVERTEBRAL GANGLIA FOLLOWS THE BLOOD SUPPLY FROM WHERE THE AORTA BIFURCATES TO THE LEFT AND RIGHT RENAL ARTERIES.
Term
HOW DO WE GET SNS IN OUR EYE FOR EXAMPLE?
Definition
THROUGH THE PARAVERTEBRAL GANGLIA. WHAT HAPPENS IS FROM T1 IT ENTERS THE PARAVERTEBRAL GANGLIA AND THEN ASCENDS THROUGH THE INFERIOR, MIDDLE, AND SUPERIOR GANGLIA THEN SYNAPSES AND THEN EXITS.
Term
HOW DOES INNERVATION GET TO OUR EYE?
Definition
IT FOLLOWS THE BLOOD SYSTEM.
Term
BECAUSE THE WAY THE PREGANGLIONIC FIBERS ENTER THE PARAVERTEBRAL GANGLIA AND THE WAY THAT POSTGANGLIONIC FIBERS EXIT THE PARAVERTEBRAL GANGLIA ARE DIFFERENT, WE HAVE 2 ANATOMICAL STRUCTURES. WHAT ARE THESE CALLED?
Definition
GREY RAMIS COMMUNICANS AND WHITE RAMIS COMMUNICANS.
Term
ARE POSTGANGLIONIC FIBERS OF THE SNS MYELINATED OR NONMYELINATED?
Definition
NONMYELINATED
Term
DESCRIBE HOW A SNS STIMULATION IS PASSED THROUGH THE PARAVERTEBRAL COLUMN.
Definition
THE CELL BODY OF THE PREGANGLIONIC FIBER IS IN THE IML. IT PASSES THROUGH THE VENTRAL HORN THEN THE VENTRAL ROOT. IT THEN ENTERS INTO THE SPINAL NERVE. IT COMES TOWARDS THE ANTERIOR PRIMARY RAMIS (DOESN'T ENTER) AND THEN THE PREGANGLIONIC FIBER ENTERS INTO THE PARAVERTEBRAL GANGLIA VAI THE WHITE RAMIS COMMUNICANS BECAUE THE PREGANGLIONIC FIBERS ARE MYELNINATED. WE SYNAPSE RIGHT HERE AT THE PARAVERTEBRAL GANGLIA THEN EXIT VIA THE GREY RAMIS COMMUNICANS. THE GREY RAMIS COMMUNICANS IS GOING TO BRING IT BACK TOWARDS THE SPINAL NERVE AND THEN THOSE POSTGANGLIONIC FIBERS CAN THEN ENTER EITHER THE ANTERIOR OR POSTERIOR PRIMARY RAMIS.
Term
IF YOU HAVE TOUCH ON THE ANTERIOR PART OF BODY WHERE ARE THE SENSORY AFERENTS GOING TO TRAVEL?
Definition
THEY WILL TRAVEL BACK TOWARDS THE SPINAL CORD IN THE ANTERIOR PRIMARY RAMIS INTO THE SPINAL NERVE.
Term
IF YOU HAVE TOUCH ON THE POSTERIOR PART OF THE BODY WHERE ARE THE SENSORY AFFERNTS GOING TO TRAVEL?
Definition
THEY WILL TRAVEL BACK TOWARDS THE SPINAL CORD IN THE POSTERIOR PRIMARY RAMIS AND ENTER INTO THE SPINAL NERVE.
Term
HOW DOES SENSORY INFORMATION GET TO THE EYE?
Definition
IT BEGINS AT T1. THE IML, PREGANGLONIC EXITS THE VENTRAL ROOT, SPINAL NERVE AND GOES INTO THE PARAVERTEBRAL GANGLIA AND DOES NOT SYNAPSE BUT CONTINUES UP AND PASSES THROUGH THE INFERIOR AND THEN THE MIDDLE AND ENDS AT THE SUPERIOR CERVICAL GANGLIA AND SYNAPSES. FROM THE SUPERIOR CERVICAL GANGLIA, THE POSTSYNAPTIC FIBER EXITS AND HITCH A RIDE ON THE ARTERY TO THE MUSCLE OF THE EYE.
Term
IF YOU CUT BETWEEN THE SUPERIOR AND MIDDLE GANGLIA WHAT WILL HAPPEN?
Definition
YOU WILL HAVE UNILATERAL EFFECTION. YOU WILL HAVE LOSS OF SYMPATHETIC RESPINSE TO HALF OF THE FACE. EX. UNILATERAL PUPILLARY DILATION.
Term
CAN YOU ASCEND AND DECEND THROUGH THE PARAVERTEBRAL GANGLIA?
Definition
YES. THAT IS HOW SWEAT GLANDS CAN BE STIMULATED THROUGHOUT THE BODY.
Term
DESCRIBE THE INNERVATION OF THE ADRENAL MEDULLA.
Definition
IT STARTS IN THE IML TO VENTRAL HORN TO SPINAL NERVE TO WHITE RAMIS TO PARAVERTEBRAL GANGLIA WITH NO SYNAPSE TO ABDOMINAL SPLANCHNIC NERVE ALL THE WAY TO OUR ADRENAL MEDULLA. THE SYNAPSE OCCURS ON THE CROMAGGIN CELLS. Nn RECEPTORS.
