Spinal Marrow description:
Spinal cord is a thin nerve is an extension of the central nervous system of the brain and the vault and protected by the spine. The main function of bone marrow is the transmission of income between the periphery and brain stimulation.
In cross section the spinal cord seems white exterior, while the portion in the shape of butterflies and the color gray.
In cross sections are part of the spinal cord such as wings, consisting of upper wings is called the dorsal horn and the bottom wing is called the ventral horn. Dihantar sensory impulses from receptors into the spinal cord through the dorsal horn and motor impulses from the spinal cord via the ventral horn toward the effector. In the dorsal horn of nerve cell bodies have a liaison (association connector) that receives impulses from sensory nerve cells and will delivered into the motor nerve.
In the whites there are association of nerve fibers. A collection of nerve fibers formed nerve (nerve). Nerves that carry impulses to the brain is an ascending channel, and which carry impulses from the brain in the form of the command is a descending channel.
