Central nervous system
The CNS also includes the retina and the optic nerve (cranial nerve II), as well as the olfactory nerves (cranial nerve I) and olfactory epithelium as parts of the CNS, synapsing directly on brain tissue without intermediate ganglia. As such, the olfactory epithelium is the only central nervous tissue in direct contact with the environment, which opens up for therapeutic treatments.
where are cranial nerves 1 and 2 located In the cerebrum what is its anatomy? The cerebrum is the largest part of the brain; The cerebrum consists of two C-shaped cerebral hemispheres, separated  by a longitudinal fissure. what are its main function? It functions as the center of sensory perception, memory, thoughts and judgement; the cerebrum also functions as the center of voluntary motor activities. how are there named? The cerebral cortex, Cerebral hemispheres are they named based on their functions? Yes -  the right celebral hemisphere controls and processes signals from the left side of the body, while the left celebral hemisphere controls and processes signals from the right side of the body. what are the functions nerves 1 and 2 (mentioned in the beginning)? The olfactory nerves (I) transmit nerve impulses about odors to the central nervous system.  The optic nerves (II) transmits visual information from the retina to the brain. what are the other nerves that perform other functions? The oculomotor nerve (III), trochlear nerve (IV) and abducens nerve (VI) coordinate eye movement. The trigeminal nerve (V) provide sensation to the skin of the face and also controls the muscles of chewing. The facial nerve (VII) controls most muscles of facial expression etc what are the neuroanatomy involved in eye movement? The oculomotor nerve, which controls the majority of the muscles, the trochlear nerve, which controls the superior oblique muscle, and the abducens nerve, which controls the lateral rectus muscle. what are saccades? Saccades are the rapid movement of eyes that is used while scanning a visual scene.

Central nervous system [SEP] Introduction
The central nervous system (CNS) is the part of the nervous system consisting primarily of the brain and spinal cord. The CNS is so named because it integrates the received information and coordinates and influences the activity of all parts of the bodies of bilaterally symmetric animals—i.e., all multicellular animals except sponges and radially symmetric animals such as jellyfish—and it contains the majority of the nervous system. The CNS also includes the retina and the optic nerve (cranial nerve II), as well as the olfactory nerves (cranial nerve I) and olfactory epithelium as parts of the CNS, synapsing directly on brain tissue without intermediate ganglia.
