The cranial nerve exam is a type of neurological examination.It is used to identify problems with the cranial nerves by physical examination.It has nine components. Each test is designed to assess the status of one or more of the twelve cranial nerves (I-XII).
Cranial nerves are the nerves that emerge directly from the brain (including the brainstem), of which there are conventionally considered twelve pairs. Cranial nerves relay information between the brain and parts of the body, primarily to and from regions of the head and neck , including the special senses of vision , taste , smell , and hearing .
Sometimes: cranial accessory, spinal accessory. Mainly motor Cranial and Spinal Roots Located in the jugular foramen. Controls the sternocleidomastoid and trapezius muscles, and overlaps with functions of the vagus nerve (CN X). Symptoms of damage: inability to shrug, weak head movement. XII Hypoglossal: Mainly motor Medulla
A neurological examination is the assessment of sensory neuron and motor responses, especially reflexes, to determine whether the nervous system is impaired. This typically includes a physical examination and a review of the patient's medical history, [1] but not deeper investigation such as neuroimaging.
In the head and neck, cranial nerves carry somatosensory data. There are twelve cranial nerves, ten of which originate from the brainstem, and mainly control the functions of the anatomic structures of the head with some exceptions. One unique cranial nerve is the vagus nerve, which receives sensory information from organs in the thorax and ...

The cerebellum provides the motor control that allows people to maintain balance by integrating three types of sensory input: vestibular (inner ear and eight cranial nerves), proprioceptive (peripheral nerves and dorsal columns of the spinal cord), and visual (eyes and second cranial nerves). Now, Romberg's test evaluates postural instability ...
