because they are rooted from spinal cord
.
Cranial nerves emanate from the brain stem. Spinal nerves are rooted in the spinal cord.
Has cervical plexus.
Bcoz I have learn it
ππ
BECAUSE CRANIAL NERVES ARE LOCATED IN THE BRAIN, NOT THE CERVIAL SPINE
because this have 31 sets of nerves
The spinal cord starts after the brainstem, so cranial nerves above the brainstem are above the neck.
Incidentally, the Brain-Stem is NOT in the neck, but lies at the bottom of the brain. And, come to think of it, I think the ONLY Cranial nerve which passes through the neck is the Vagus (CN X).

The eight C-Spine spinal nerves pass from the cord (and vertebral bodies), and extend to..e.g., the upper extremities, while the Cranial nn. pass from the Brain-Stem and down and out, through distinct foramina lying on the bottom (inferior aspect) of the skull (and do not pass down within the Spinal Cord). In clinical practice, we have found that the upper cervicals do affect the ANS fed organs (perhaps via cord-torsion), but the connections are not at all as clear as those between the spinal nerves and the arms and fingers, say.

because
the brainstem is in the neck
Because it **** says so 2 lines up- duh.
we have more spinal nerves than cranial nerves.
cranial nerves have their course mainly in the facial region while the spinal nerve (cervical branches) arise from the spinal cord and spread in the neck region
cervical plexus
because spinal nerves starts from the cervical spine
pusssy
spinal is connected all the way to the neck go to brain.
Because the cranial nerves has 2 extending to the neck and the spinal nerves has 8 cervical nerves
The neck is made up of the 8 cervical nerves.
because of the spinal cord, which is the way, where messages pass through going to the brain.
it was just a guess
because in the explanation of spinal nerves we saw that we have cervical 1-8 nerves but for the cranial nerves they are situated in the head(cranial).
because cranial nerves are in the brain stem
