Optic Nerve Anatomy. Neurons are the basic unit of nervous tissue. It is a mixed nerve that contains parasympathetic fibers and has the most extensive distribution of the cranial nerves. The optic nerve size changes in early life and is likely stable after age 10. The symptoms of a pinched nerve in the back sometimes also affect surrounding areas. Nerve: Nerves are found only in the peripheral nervous system. Definition. It is made up of multiple pieces of tough cartilage, surrounded and held together by fibrous tissues, membranes, and ligaments [3].The largest cartilaginous segment is called the thyroid cartilage, with a prominent bulging known as Adam’s apple. The femur is the only bone located within the human thigh. A pinched nerve occurs when a nerve root has become compressed by a bone, disc, tendon, or ligament. human anatomy Denoting the front surface of the body; often used to indicate the position of one structure relative to another, i.e., situated nearer the front part of the body.
