where does the spinal cord begins and where does it end? | Begins as a continuation of the medulla oblongata and extends to the level of L1-L2 or C1-L1 |
What bundle of nerves continue into the tunnel after spinal cord ends? | Cauda Equina |
What's the order of the meninges? | Spinal cord then ->1)Pia (is on the inside) 2) Arachnoid 3) Dura mater |
where is the cerebral spinal fluid found? | Found in the Arachnoid- within the subarachnoid space and cavities and canals of the brain and spinal cord. Several ways to think of this is in the subarachnoid space and it’s also in between the arachnoid and the pia. |
What's the difference between white matter and grey matter? | Gray matter: Cell bodies and synapses (the connections) White matter: Myelinated axons. The wires. |
the number of spinal nerves | 31 pairs and how many of each one 8 12 5 5 1 (8 cervical, 12 Thoracic, 5 lumbar, 5 sacral, 1 Coccyxgeal) |
What is the rule about the correspondence between the nerves and the vertebra? | The first 7 exit above ? The rest below so if you’re in the next you look down if you’re in the body you look up |
Know the names of the connective tissue layers around the spinal nerves around and the inside one: | Epineurium, Perineurium, endoneurium. |
The difference between the dorsal and central root | one a sensory and one is motor |
What’s in the dorsal root ganglia | The dorsal root ganglion contains the cell bodies of sensory neurons that bring information from the periphery to the spinal cord. These neurons are pseudounipolar and contain an axon-like |
Sensory nerve cell body | |
What is the sensory nerve cell body? | |
No cell bodies on feet. | |
What are the nerve plexuses ? | |
what you have to know about them is that they come from the ventral ramuses not the dorsal | |
What plexus goes to the front of the lower limb ? Lumbar and the back of the lower limb is sacrum ? | |
Distribution of rami | Some places you need to label which nerve |
