The only sensation that does not pass through the thalamus.

Insufficiency of accommodation leads to difficulty focusing on close objects.

Inability to recognize odors, can be unilateral or bilateral.

Abnormal smell sensations, can be unpleasant or distorted.

Inability to perform purposeful actions despite having intact muscles.

The auditory reflex center in the brain.

The visual reflex center in the brain.

Part of the brain that controls behavior and personality.

The ear drum that transmits sound vibrations.

The upper, weaker part of the tympanic membrane.

A skull opening for the mandibular nerve.

Nerve I for sense of smell, passing through the cribriform plate.

Normal vision where light focuses directly on the retina.

Short-sightedness; light rays focus in front of the retina.

An opening for the optic nerve to enter the skull.

Cranial Nerve VII that controls facial expressions.

Most tongue muscles are supplied by the hypoglossal nerve, except the genioglossus muscle which is innervated by the mandibular nerve.

The middle part of the nucleus solitarius receives taste sensations from the posterior one-third of the tongue via the glossopharyngeal nerve.

The intracranial part of the facial nerve supplies the stapedius muscle, while the extracranial part supplies the anterior and posterior belly of the digastric muscle.

All palatine muscles are supplied by the cranial part of the accessory nerve through the vagus nerve, except the tensor palatini muscle, which is supplied by the mandibular nerve.

A bilateral lesion of the lateral part of the optic chiasm leads to bi-nasal hemianopia.

The corneal reflex assesses the afferent pathway of the trigeminal nerve and the efferent pathway of the facial nerve.

The foramen of Monro is bounded anteriorly by the fornix and posteriorly by the thalamus.

All parts of the corpus callosum are supplied by medial cerebral artery, except the splenium, which is supplied by the posterior cerebral artery.

A branch of the internal carotid artery supplying the retina.

Abbreviation for 'Oculus Dexter', meaning the right eye.

Abbreviation for 'Oculus Sinister', meaning the left eye.

Visual acuity measurement indicating reduced vision in the left eye.

Photoreceptor cells responsible for color vision.

Structure where optic nerves partially cross.
