Nervous system
the brain,spinal cord and the nerves
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).
neuron
Connective, epithelial, muscular and nervous.
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 .
The brain belongs to the Central Nervous System(CNS) of the human Nervous System.
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 basic functional unit of the nervous system is the neuron.
Nervous tissue is the main component of the two parts of the nervous system which are the brain and spinal cord of the central nervous system. It is also the main component of the branching peripheral nerves of the peripheral nervous system, which regulates and controls bodily functions and activity.
