Nervous tissue makes up most of which structures?Multiple select question.the spinal cordthe braincartilagenerves

Nervous tissue primarily makes up the following structures:

1. The Spinal Cord: The spinal cord is a long, thin, tubular structure made up of nervous tissue, which extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column.

2. The Brain: The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. It is made up of a complex network of neurons and is the control center for the body's functions and abilities.

3. Nerves: Nerves are bundles of long fibers called axons, which are made up of nerve cells. They transmit signals between the brain and the rest of the body, allowing for communication and coordination.

Cartilage, however, is not made up of nervous tissue. It is a flexible connective tissue found in many areas in the bodies of humans and other animals, including the joints between bones, the rib cage, the ear, the nose, the bronchial tubes, the intervertebral discs, and others.
