Yes,I do think so that brain does contain nerves.
Just about all of them. Some have more, some less. But all have vessels and nerves to a degree.
Cranial nerves VII, IX and X are called mixed nerves because they contain both motor and sensory nerves.
Spinal nerves are said to be mixes because their posterior roots contain sensory axons and their anterior roots contain motor axons.
Nerves are like trees. The have branches call axons.
The reason why a peripheral nerve such as the sciatic nerve can contain nerve fiber from several spinal nerves is owing to nerve plexuses. These are networks of nerves all tangled together and found mostly in the limbs.
Yes, the connective tissues of the epimysium contain the blood vessels and nerves that supply the muscle fibers
Yes, we have nerve cells.
All the spinal nerves in their distribution are mixed nerves
Bones contain nerves and blood vessels. The nerves and blood vessels go though channels in the bone, so that bone cells (osteocytes) have nutrition and commands from the nervous system. Broken bones hurt a lot, which is one way you know there are nerves in them!
Hair, fingernails and toenails, which can be cut without feeling any pain (or sensation of any kind) do not contain nerves, although the roots do contain nerves, so you do feel pain if these are ripped out. Callouses also do not contain nerves.
