- Transmit sensory information from periphery to brain
23
Q
Medulla Oblongata
A
- Continuous with spinal cord
- Pyramid (center)
- Olive (lateral)
24
Q
Cerebellum
A
- Coordination of voluntary movement
- Balance & equilibrium
- Integrates proposed movement with current body position
- Corrects ongoing movements
25
White Matter Spinal Cord
- Periphery
- Longitudinal tracts of axon (sensory & motor)
26
Grey Matter Spinal Cord
- Central H
- Neuron cell bodies
- Glial cell bodies
- Dorsal horn
- Ventral horn
27
Dorsal Horn
- Sensory
28
Ventral Horn
- Motor
29
Ventricles Function
- Large fluid filled cavities in brain
- Produce CSF
30
Cerebral Spinal Fluid (CSF)
- Surrounds brain & spinal cord
- Within subarachnoid space
31
Ventricle Order
- Lateral ventricle x2
- Interventricular foramen
- Third Ventricle
- Cerebral aquaduct
- Forth Ventricle
- Central canal
32
Meninge Types
- Dura mater
- Arachnoid mater
- Pia mater
33
Dura Mater
- Thickest meninge type
- Protect brain
- Wrap around nerves exiting spinal cord
- Exterior layer
34
Pia Mater
- Thinnest meninge type
- Into sulci of brain
- Surface of spinal cord
- Can't be pealed off, painted into brain grooves
35
Arachnoid Mater
- Thin
- White & wispy
36
Meninges Function
- Supportive framework for vasculature
- Protect CNS from mechanical damage
- Provide tether points for brain
37
Arachnoid (Subarachnoid) Space
- Filled with cerebrospinal fluid
- Provide cushioning
38
Subdural Space
- Venous blood
- Between dura & arachnoid
39
Extracerebral Hemorrhage
- Between skull & brain
- Increased intracranial pressure
40
Epidural Hematoma
- Bleed above dura
- Arterial blood
41
Subdural Hematoma
- Bleed below dura
- Above arachnoid mater
- Venous blood
42
Subarachnoid Hemorrhage
- Arterial blood
- Subarachnoid space
43
Epidural Space
- Fat filled area
- Above dura
- Contains blood vessels
- No puncture to dura
44
Lumbar Puncture Function
- Sample cerebrospinal fluid
- Spinal anesthesia
45
Epidural Function
- Provide anesthetic
46
Lumbar Puncture & Epidurals
- Inserting needle into lumbar region
- Access spinal cord
- Below level of conus medullaris (L1-L2)
- Epidural fat last layer punctured
47
Lumbar Cistern
- Sample, inject
- Outpouching area in subarachnoid space
- Filled with cerebrospinal fluid
