the brain, spinal cord and peripheral nerves
Nervous system
Nervous tissue is one of the four basic building block tissues in the human body (epithelial, connective and muscle tissue being the other three). Nervous tissue exists either as part of the central nervous system (CNS; brain and spinal cord) or the peripheral nervous system (PNS; cranial and peripheral nerves and ganglia). I assume this is what your question refers to.
peripheral nervous systemthe peripheral nervous systemperipheraThe peripheral nervous system branches from the central nervous systemIt is called the Peripheral Nervous System(PNS).
A single nerve cell is called a neuron. A neuron carries electric pulses through the nerves in the nervous system. The neuron is the basic unit in the nervous system.
The main difference is that the nervous system controls and coordinates different functions of body and is made up of nervous tissues while respiratory system includes lungs trachea nasal cavities and is concerned with breathing ,its main functional tissues are epithelial and muscular .
Connective tissue and nervous tissue.

The effector tissues of the endocrine system are the endocrine glands. Messages from the endocrine and nervous system cause these glands to alter production of hormones.
The brain belongs to the Central Nervous System(CNS) of the human Nervous System.

The nervous system is made of neurons (cells) and their supporting connective tissues.
