Spinal Cord Basics
Cranial Meninges
Spinal Meninges
100
A center with a discrete anatomical boundary
What is the NUCLEUS?
100
Groupings of neuron cell bodies.
What is a ganglia?
100
What is the function of the spinal cord?
what is relaying information to and from the brain?
100
These membranes are between the cerebrum and the cranium
What are the cranial meninges?
100
Layers that surround and protect the spinal cord.
What are the spinal meninges?
200
Covering of brain portions; made up of neuron cell bodies
What is GRAY MATTER?
200
Nerves that go to and from the spinal cord.
What is a spinal nerve?
200
the four nerve sections of the spinal cord Hint: the names are similar to the sections of vertebrae
what are Cervical spinal nerves, Thoracic spinal nerves, Lumbar spinal nerves, and Sacral spinal nerves?
200
These spaces are in between the arachnoid.
What are subarachnoid spaces?
200
The space that contains adipose tissue in the spinal meninges
What is the epidural space?
300
Bundles of axons (tracts) that share origins, destinations, and functions
What is WHITE MATTER?
300
Nerves that travel to and from the brain.
What is a cranial nerve?
300
what gray matter appears as
what are horns?
300
This would be under the pia mater
What is the cerebral cortex?
300
This is underneath the epidural space.
What is the dura mater?
400
NEURAL CORTEX
What is grey matter on the surface of the brain?
400
The gray matter (neuron cell bodies) are located here in the PNS.
What are ganglia?
400
each section of the spinal cord has a pair of what three things? Its between slides 47-50 but don't cheat and look!!
what are Dorsal root ganglia, Dorsal roots, and Ventral roots?
400
This is where Cerebrospinal fluid is held
What is the dura sinus?
400
This meningeal layer is a layer of squamous cells that contains lymphatic fluid.
What is the arachnoid?
500
1. Bundles of CNS axons that share a common origin, destination, and function. 2. Several tracts that form an anatomically distinct mass
What are TRACTS and COLUMNS?
500
Nerves (bundles of axons) form this type of matter in the PNS.
What is white matter?
500
In the spinal cord a nerve impulse comes in through a _____ nerve travels in through a _______ root and leaves through a ________ root? Hint: slide 51
Blank 1:Spinal 2: Ventral 3:Dorsal
500
These extensions of the arachnoid in the form of clusters penetrate the inner layer of the dura mater
What are arachnoid granulations?
500
This layer is highly vascular, it supplies blood to the superficial areas of the neural cortex.
What is the Pia Mater?
