between spinous processes and transverse process
Between transverse process and vertebral body
continuous ligament that is located along the spinous processes
- Yellow ligament
- Discontinuous, runs ant to post between vertebrae
- Final barrier before epidural space
Runs transverse between vertebrae (the crunch)
C3 to C6
Gray matter of spinal cord
where synapses occurs
White matter of spinal cord
myelinated portion of spinal cord. Where the nerves are coursing to their destinations
Anterior median fissure
where the anterior spinal artery courses
Posterior medial sulcus
where the sensory information is carried in the cord
Artery of Adamkiewitz
Branch of the segmental spinal artery that typically comes off the left side and feeds the lumbar and sacral parts of the cord. Damage results in incontinence
Segmental Spinal Artery
Runs with the roots
Anterior spinal artery
runs in the anterior median fissure
# of Posterior Spinal veins
# of anterior spinal veins
Anchors occiput of head to the processes of the cervical vertebrae to C7
How many cervical nerves are there, and how many cervical vertebrae are there?
8 cervical nerves, 7 cervical vertebrae. The 1st cervical nerves comes out above C1, and nerves C2-C7 come out superiorly to the respective vertebrae. C8 comes out below C7
Internal vertebral plexus
- What you can hit doing an epidural.
- Is in the epidural fat
- Anchors cord where the spinal roots leave.
- 21 pairs
- L1 in adults and L3 in kiddos
- The end of the cord
anchors cord to the coccygeal bones. Is an outcropping of the pia and dura maters. Dura mater actually attaches to the bone
Superior sagittal sinus
- In the groove between the hemispheres.
- Where the arachnoid granules are.
- Formed between two dural layers
Drains the posterior part of the brain
collection of arachnoid villi: in the superior sagittal sinus. Reabsorbs CSF
Between the two lobs of the cerebral hemispheres in the deep longitudinal fissure
Thick, against the skull. 2 layers
Avascular layer between the pia and dura mater.
Thin delicate layer that lies directly on top of the brain
Horizontal divider between the cerebral and cerebellar parts of the brain
- infundibulum goes thru here
- Hypothalamus sits on this
- voluntary movement
- Broca's Area
- Wernecke's Area
comprehension of language
coordinates motor activities
- Temperature regulation
- emotional responses
- Salt regulation
- Food and water intake
- circadian rhythm
- works with the medulla for respiratory regulation
- Relay center for the cerebellum.
- Pneumotaxic center
Regulation of resp and HR
major fiber tract connecting the left and right cerebral hemispheres
separates the left and right lateral ventricles of the brain
major fiber tract that in in contact with the lateral ventricles
Aqueduct of sylvius
- Connects 3rd and 4th ventricles.
- The primary cause of hydrocephalus is stenosis of the cerebral aqueduct
- word formation
- In the frontal lobe
In the pariateal lobe
What three cranial nerves make the eye move?
- 3, 4, 6
- 3- occulomotor
- 4- superior oblique muscle
- 6- lateral rectus muscle
