Detailed explanation-1: -Nervous tissue helps in the control and co-ordination of the body. It is made up of long nerve cells called neurons. These cells are bound together by connective tissue to form a nerve. Nerves are connected to the brain and the spinal cord.
Detailed explanation-2: -C fiber axons are grouped together into what is known as Remak bundles. These occur when an unmyelinated Schwann cell bundles the axons close together by surrounding them. The Schwann cell keeps them from touching each other by squeezing its cytoplasm between the axons.
Detailed explanation-3: -Nerves are a combination of many nerve fibers located in the brain and spinal cord. The cerebrum contains two structures, the thalamus and hypothalamus. The pons is reponsible for reflex actions including, chewing, tasting, and saliva production. The spinal cord ends at the fourth or fifth lumbar vertebra.
