Nervous or the nerve tissue is the major tissue of our nervous system. It monitors and regulates the functions of the body. Nervous tissue consists of two cells: nerve cells or neurons and glial cells, which helps transfer nerve impulses and also gives nutrition to neurons.

The spinal cord is a component of the Central Nervous System. Its main function is to communicate nerve signals and impulses from the different organs of the body to the brain. It is connected to the brain via the Brain Stem and is protected by thirty-three irregularly shaped bones that comprises the spinal column, otherwise known as the vertebrae.
The spinal cord is a vital part of the central nervous system (CNS). It acts as a communication highway, transmitting signals between the brain and the rest of the body. It also controls reflexes, which are automatic responses to stimuli. The spinal cord is protected by the vertebrae, cerebrospinal fluid, and meninges. Damage to the spinal cord can result in loss of sensation, motor function, or paralysis, depending on the severity and location of the injury.
This is a picture of the spinal cord of a frog seen under the microscope and from the looks of the angle i believe that it is cut in a cross sectional way. In the middle, there's a butterfly-shaped part called the gray area where the nerve cells are found. Around it is the white area that has the nerve fibers. You can also see the alar plate and basal plate, which help with sending and receiving signals. The spinal cord is covered by thin layers called pia mater and dura mater that protect it. This part of the body helps pass messages between the brain and the rest of the body.
In this microscopic photo of the spinal cord of a frog, you can see the three meninges—dura mater (outer tough layer), arachnoid (middle web-like layer), and pia mater (thin inner layer hugging the cord). The image also shows the alar plate (which handles sensory info coming in) and the basal plate (which controls motor signals going out). Together, they help the spinal cord process and send messages between the frog’s brain and body.
The spinal cord is found in the CNS. It is composed of nervous tissue, specifically gray and white matter, which work together to transmit signals between the brain and the rest of the body.
