Where is the nerve cord located?

A nerve cord is a single hollow tract of nervous tissue that forms the central nervous system of chordates and develops into the spinal cord and brain in vertebrates.

The nerve cord occurs below the notochord. The notochord provides sites for the attachment of the skeletal muscles. The nerve cord coordinates the functions of the body.

Humans are not chordates because humans do not have a tail. Vertebrates do not have a notochord at any point in their development; instead, they have a vertebral column.

In contrast to the chordates, other animal phyla are characterized by solid nerve cords that are located either ventrally or laterally. The nerve cord found in most chordate embryos develops into the brain and spinal cord, which comprise the central nervous system.

[Extra information:

The nerve impulse is an electrical phenomenon through which nerve cells (neurons) communicate with each other. It is generated due to the difference in electric potential between two ends of the nerve region.

The nerve impulse in our body travels in the form of electrical impulses.

  • The information acquired at the dendrites of the neuron sets off a chemical reaction that helps to create an electric impulse.
  • This impulse collected through dendrites travels from the cyton along the axon and reaches the nerve endings.]
