APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Cranial nerves transmit sensory information, including touch, vision, taste, smell, and hearing. Nerves that connect the spinal cord with other parts of the body are called spinal nerves. The brain communicates with most of the body through the spinal nerves.

Detailed explanation-2: -Cranial nerves, spinal nerves, and ganglia make up the peripheral nervous system. The afferent division of the peripheral nervous system carries impulses to the CNS; the efferent division carries impulses away from the CNS. There are three layers of meninges around the brain and spinal cord.

Detailed explanation-3: -In summary, the motor components of cranial nerves transmit nerve impulses from the brain to target tissue outside of the brain. Sensory components transmit nerve impulses from sensory organs to the brain.

Detailed explanation-4: -The olfactory nerve carries impulses for the sense of smell. The optic nerve carries impulses for the sense of sight. The occulomotor nerve is responsible for motor enervation of upper eyelid muscle, extraocular muscle and pupillary muscle.
