| 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. |

| 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. |
|

|
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. |

| WHERE ARE THE CELL BODIES OF THE PREGANGLIONIC FIBERS OF THE PNS FOUND AT? |

| 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
|
|
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
|
|
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. |
