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.
Everywhere. Every organ in our body is made by tissues.

Tissue is an ensemble of cells that make up the organs in the body. Stem cells are cells that can be transformed into any of the specialized cells that can be found in the tissues of the human body.
All living cells,tissues,organs including the functional system in a living body can be effected by the network of neural system co ordinated by the human brain.
Neurons originate from neural stem cells in the developing embryo, primarily in the neural tube.
The most common protein in the human body is collagen, which is found in connective tissues, skin, tendons, and bones. Collagen provides structure and support to various tissues and organs in the body.
In the brain where all the tissues for a collective job that helps make the nerves more attractive.
Cholesterol can be found in various places in the human body such as cell membranes, tissues, and blood. It is produced in the liver and can also be obtained through dietary sources like animal products.
Collagen is the protein that provides mechanical support and tensile strength for the body's tissues. It is the most abundant protein in the human body and is found in skin, tendons, ligaments, and bones.
Liver
Cells in the human body that have a large number of mitochondria are typically found in tissues that require a lot of energy, such as muscle cells and liver cells.
Lyase enzymes are found throughout the human body, with different specific lyase enzymes located in various organs and tissues. They play critical roles in various metabolic pathways by catalyzing the removal or addition of functional groups to substrates. Examples include carbon-carbon lyases found in the liver and kidney that are involved in amino acid metabolism.
