Are dermatomes skin segments that relate to sensory innervation regions of the spinal nerves?
Yes. A dermatome is a segment, or area, of the skin that has on innervation into a spinal nerve root. What is fascinating about this is that the nerve root does not only serve the skin in that area, but also the muscle, bone, and organs associated with that specific dermatome nerve root.
What is a dermatome?
dermatome is a surgical instrument used to produce thin slices of skin from a donor area, in order to use them for making skin grafts A dermatome is also the area of distribution of a nerve's cutaneous sensation.
What is sensory cutaneous innervation?
Sensory cutaneous innervation refers to the nerve receptors in the skin. There are many nerve receptors that measure things like touch, pressure, vibration, and temperature in the skin. The most notable of these are the Merkle disks, Meissner corpusles, Pacianian corpusles, and the Ruffi end organs. Then there are also hair follicle receptors and Krause end bulbs. They all form a network that is sometimes referred to as a dermatome, which is an area of the skin that is innervated by a single nerve root on the spinal cord.

What is Dermatotome?
The area of skin supplied by a single nerve is called a dermatome.
Why would there be no deficit in sensory function after a left frontal bleed?
You have motor area in front of the central sulcus. You have sensory area behind the central sulcus. So in this type of bleeding the sensory area is not affected.
What is false about sensory memory?
Sensory memory consolidates all sensory inputs into one holding area withing the brain
