The Rinne test involves using a tuning fork to distinguish between conductive hearing and sensorineural hearing. Conductive hearing relies on vibrations being conducted through the ossicles of the middle ear. Sensorineural hearing is the transmission of sound stimuli through the neural components of the inner ear and cranial nerve.
Cranial nerves III, IV, and VI are usually tested together as part of the cranial nerve examination. The examiner typically instructs the patient to hold his head still and follow only with the eyes a finger or penlight that circumscribes a large "H" in front of the patient.
V 3 (mandibular nerve) is located in the foramen ovale. Receives sensation from the face, mouth and nasal cavity, and innervates the muscles of mastication. VI Abducens: Mainly motor Nuclei lying under the floor of the fourth ventricle Pons. Located in the superior orbital fissure. Innervates the lateral rectus, which abducts the eye. VII Facial
Mental status examination, often including the abbreviated mental test score (AMTS) or mini mental state examination (MMSE) Global assessment of higher functions; Intracranial pressure is estimated by fundoscopy; this also enables assessment for microvascular disease. "A&O x 3, short and long-term memory intact" Cranial nerve examination
Romberg's test, Romberg's sign, or the Romberg maneuver is a test used in an exam of neurological function for balance. The exam is based on the premise that a person requires at least two of the three following senses to maintain balance while standing: proprioception (the ability to know one's body position in space)
Light from a single point of a distant object and light from a single point of a near object being brought to a focus. The accommodation reflex (or accommodation-convergence reflex) is a reflex action of the eye, in response to focusing on a near object, then looking at a distant object (and vice versa), comprising coordinated changes in vergence, lens shape (accommodation) and pupil size.
The Parks–Bielschowsky three-step test, [1] also known as Park's three-step test or Bielschowsky head tilt test, [2] is a method used to isolate the paretic extraocular muscle, particularly superior oblique muscle and trochlear nerve (fourth cranial nerve), [3] in acquired vertical double vision. [4] It was originally described by Marshall M ...
The Cincinnati Prehospital Stroke Scale (abbreviated CPSS) is a system used to diagnose a potential stroke in a prehospital setting. [1] It tests three signs for abnormal findings which may indicate that the patient is having a stroke.
