Nervous tissue consists of brain tissue, cranial nerves, spinal nerves, and peripheral nerves contained in the different nervous systems. For example, the central nervous system or CNS is composed of the brain and spinal cord. The brain is housed in the cranium and the spinal cord is housed in the vertebral column. Motor and sensory nerves originate from different locations and have different functions. Cranial nerves originate from the base of the brain and travel to various locations in the body. Some cranial nerves have motor functions and some have sensory functions. Peripheral nerves travel to distant parts of the body, they too are also motor and sensory depending upon which nerve you are talking about.
Nervous tissue, like other types of tissues are highly specialized. They have unique structures and very unique functions.
