Cervical Spine Anatomy - Everything You Need To Know - Dr. Nabil Ebraheim

Dr. Ebraheim’s educational animated video describes the Anatomy of the Cervical Spine.
C1 is a ring. At the upper cervical region, the spinal canal is 2.5 times larger than the cord size. 50% flexion-extension is between occiput & C1. 50% of neck rotation is between C1 and C2. C5-C6 is more prone to disc degeneration due to anatomical and mechanical forces centered at this level. There are 8 cervical nerve roots. These nerves exit on or above each vertebra C8 exits above T1. Disc prolapse occurs due to rupture of the annulus fibrosus and protrusion of the nucleus pulposus which compresses the nerve root. The most common type of disc prolapse is posterolateral disc prolapse. C2 ganglion may be vulnerable to compression/entrapments due to:
•Cervical arthritis causing repeated mechanical damage or compression
•Post traumatic hyperextension injuries (whiplash injury)
•C2 Ganglion entrapment/ compression causes cervicogenic headache
The incidence of vertebral artery increases if the fracture extends into the foramen transversum. This may manifest as impaired consciousness, drowsiness, syncope, ataxia, brain-stem and cerebellar ischemia/infarction, dysarthia, headache, vertigo, visual impairment, and ptosis. Bilateral or dominant vertebral artery injury can cause fatal ischemic damage to the brain stem and cerebellum. Delayed cortical blindness and recurrent quadriparesis can also occur from occult vertebral artery injury after cervical trauma. The great majority of vertebral artery injuries are clinically silent. The majority of patients with vertebral artery injuries had flexion-distraction or flexion-compression types of spinal injuries.

you are getting me through my physiotherapy exams!thank you!!!

[@draznitelka]

yayy, your videos are great! just great, really gives me an idea how things are so now i can visualize them easier (its a really good idea how you show the same structures in different angles) Thanks a lot

[@ThomasAntonyENT]

THANKS A LOT! I AM INTERESTED IN CERVICOGENIC HEADACHE AND THIS VIDEO HAS HELPED ME A LOT IN UNDERSTANDING THE SAME !

Hey - Dr Ebraheim, I really enjoy your videos and find them very instructive. At 4:04 on this video, the word injury is missing in the caption on the left after the words vertebral artery. Sandy J. Murray MD

[@nabilebraheim]

thanks

[@noamanali9023]

can you till me dr:Nabil is there is a relationship between cervicogenic headache and C2 ganglion that is present beneath C1 and responsible for eye nerve supply and pineal gland. vestibular system

[@nabilebraheim]

you are correct thanks i have several ones that are very good

Why do ppl in my family have that hump where the back of the neck meets the spine? What is that? Can it be fixed?

[@dhafernoori1039]

Great help, Thanks a lot

[@user-vz5qh5xk1r]

Dr I am broken lateral orbit eyebsocket ( orbitofrontal) I cant hang with my neck down My atalntoaxial was changed Vagus nerve is become impaired due to The zygomatics flaoting The trapezius mascule is tilted one side 5he side of my body was tilted 😢 Dr How can l recover without any surgery

[@mrgeography82]

How do you reverse the annulus fibrosis naturally?

[@Whiteiris999]

Great work, just one doubt: I learned that c7 does not have transves foramenes and the video shows them.

[@hiraasif7816]

It does have a foramen transversarium but it is small in size because only vertebral vein passes through it.

[@rebekahmills1602]

good video - spelling correction? 2:30 should be foramen not foreamen? for foramen transversarium.

[@nellyhoffman6194]

I always read that 7 cervical vertebra but then i saw 8 cervical nerves :P That was confusing at first

[@nabilebraheim]

@Bone Man Thanks

1:58 The rotational motion is limited by the alar ligaments. Cutting one ligament increases maximum atlas axis rotation to 40 degrees on the opposite side, from a normal 30 degrees. It doesn't seem to me that this increase would lead to nerve pinches, but rather some instability of the neck as fewer tendons keeping it stable with relaxed neck muscles. The transverse ligament limits and stabilizes nodding rotation. The facet capsule does not seem to be a factor. Also instability seems to be associated more with broken dens. Occiput atlas normal rotation is minimal, around 4 degrees. Typical injury in automobile whiplash accidents are to the alar ligament. CT-functional diagnostics of the rotatory instability of upper cervical spine. 1. An experimental study on cadavers. 1987 Also has CT pictures of rotations.

[@saeedkamali2025]

Send this to upper cervical chiropractors who say nonsense about this

[@Sprinkled1]

:( This only covers half of what I have to know for my exam on C 1-7
