Head neck and spine anatomy

Question 1

What bones can you see from the anterior of the skull?

Answer 1

Mandible at the bottm (jaw)
Cheek bone just above
Nasal bone where the nose should be
Frontal bone - forehead
Zygoma - lateral side of face

Question 2

What bones can you see from the lateral view of the skull?

Answer 2

Frontal bone - just above the eye
Parietal bone at the top of the head
Occipital bone at the back of the head
Bottom side of the head is the temporal bone
Part of the sphenoid bone can be seen just past the eye and the weak spot called the pterion.

Question 3

What bones can you see from the inferior view of the skull?

Answer 3

Occipital bone around the frame and magnum at the base of the skull
Inferior part of the temporal bones
Mandible

Question 4

What bones can you see from the posterior view?

Answer 4

Parietal and occipital bone separated by lambda suture.

Question 5

What can you see from the superior view?

Answer 5

Sagittal and coronal sutures meeting at the bregma.

Question 6

What can you see on a neonatal skull?

Answer 6

Anterior fontanelle instead of bregma (soft spot) where there is unfused bone.

Question 7

What can you see on the cranial base?

Answer 7

Anterior fossa where the frontal lobe sits.

Middle cranial fossa where the temporal lobe sits.

Posterior cranial fossa where the cerebellum and brain stem sits covered in a layer of meninges.

Question 8

What can you see in each fossa?

Answer 8

Anteriorly is the cribriform plate which is part of the ethmoid bone.

Moving back a bit is the optic canal, one on either side.

Just near the optic canal is the superior orbital fissure.

Immediately behind the optic canal is the foramen rotundum.

Further behind the larger hole is the foramen ovale.

Slightly lateral to that is a very small foramen spinosum .

Looking at the posterior cranial fossa you can see the temporal bone with an internal acoustic meatus.

Larger foramen just behind that is the jugular foramen.

Finally at the back is the hypoglossal canal and the foramen magnum.

Question 9

What nerves pass through the cribriform plate?

Answer 9

Olfactory nerves

Question 10

What nerves pass through the optic canal?

Answer 10

Optic nerves

Question 11

What nerves pass through the superior orbital fissure?

Answer 11

All the nerves involved in the control of the extrinsic muscles of the eye.

Question 12

What nerves pass through the foramen rotundum?

Answer 12

The maxillary division of the trigeminal nerve passing out of the skull

Question 13

What nerves pass through the foramen ovale?

Answer 13

The mandibular division of the trigeminal nerve

Question 14

What passes through the foramen spinosum?

Answer 14

The middle meningeal artery

Question 15

What passes through the internal acoustic meatus?

Answer 15

Cranial nerves 7 and 8

Question 16

What nerves pass through the jugular foramen?

Answer 16

Cranial nerves 9,10 and 11

Question 17

What nerves pass through the hypglossal canal?

Answer 17

Cranial nerve 12

Question 18

What passes through the foramen magnum?

Answer 18

This is where the spinal cord and brain stem come together.

Question 19

What are the two layers of the dura mater called?

Answer 19

Periosteal closer to skull and meningeal closer to arachnoid.

Question 20

What is the biggest venous sinus called?

Answer 20

Superior sagittal sinus

Question 21

What is in the subarachnoid space?

Answer 21

Spider like projections and cerebral spinal fluid

Question 22

What is the role of cerebral spinal fluid?

Answer 22

Protect against movement and supply nutrients

Question 23

Where is the extra dural space?

Answer 23

Just below the foramen magnum where extradural or epidural anesthetic is applied.

Question 24

Only once one takes the anatomy final, very good vacations are heavenly

Answer 24

Olfactory, optic, oculi motor, trochlear, trigeminal, abducens, facial, vestibulocochlear, glossopharaengeal, vagus, accessory, hypoglossal
