Lab Exam 2 Flashcards
Which cranial nerve is responsible for sense of smell?
Olfactory nerve - CN I
Which cranial nerve is responsible for sight?
Optic nerve - CN II
Which cranial nerve is responsible for motor to 4 extra-ocular muscles; superior inferior and medial rectus and inferior oblique and parasympathetic to sphincter pupillae and ciliary muscles?
Oculomotor nerve - CN III
Which cranial nerve is motor to superior oblique muscle?
Trochlear nerve - CN IV
Which cranial nerve is responsible for sensory of the face and nasal/oral cavities; motor to the muscles of mastication?
Trigeminal nerve - CN V
Which cranial nerve provides motor innervation to the lateral rectus muscle?
Abducent nerve - CN VI
Which cranial nerve is responsible for sense of taste for the anterior 2/3rds of tongue, motor to the muscles of facial expression, parasympathetic to lacrimal, nasal, palatine, submandibular and sublingual glands?
Facial nerve - CN VII
Which cranial nerve is responsible for balance and hearing respectively?
Vestibulocochlear nerve - CN VIII
Which structure is a major lambic system output tract of the hippocampus? It also is necessary for memory consolidation because damage to this structure results in anterograde amnesia.
Fornix
The inability to form new memories
Anterograde amnesia
Which structure is part of the basal nuclei/basal ganglia, and is involved in learning and motor control, speech articulation, reward via goal-directed behaviors, and addiction.
Putamen
Which structure of the basal ganglia enlarges with addictive behaviors such as cocaine addiction?
Putamen
Fan like white fibers radiating above the internal capsule connecting to the cerebral cortex.
Corona radiata
Also known as the accessory oculomotor nucleus
Edinger-Westphal nucleus
This nucleus provides parasympathetic pre-ganglion is to the ciliary ganglion for the pupillary light reflex and accommodation responses of the lens
Edinger-Westphal Nucleus aka accessory occulomotor nucleus
Term for constriction of the ciliary body to make the lens rounder to see near objects
Accommodation
This nucleus senses proprioception from the muscles of mastication in the jaw. It also functions to prevent biting down hard enough to lose a tooth
Mesencephalic nucleus of the trigeminal nerve
This nucleus receives tactile discrimination and pressure sensations from the face
Chief sensory nucleus of the trigeminal nerve
Via CN VII this nucleus supplies the submandibular, sublingual, lacrimal, nasal and palatine glands
Superior salivatory nucleus
Via cranial nerve IX, supplies the parotid gland
Inferior salivatory nucleus
These structures are necessary for the recollective memory formation; and are connected to the thalamus and hippocampus.
Mammillary bodies
Significant B-1/Thiamine deficiency due to alcoholism results in Wernicke’s-Korsakoff syndrome which damages the ____ _____and the patient develops anterograde amnesia.
Mammillary bodies
This structure is involved in goal-directed behaviors as the cerebral cortex sends it sensory information as to body position.
Caudate nucleus
Which two structures make up the corpus striatum?
Caudate nucleus and lentiform nuclei
These structures contain ascending sensory tracts and descending motor tracts
Cerebral peduncles
Visual area of the thalamus
Lateral geniculate body
The optic radiations connect this structure with the primary visual cortex. This structure is part of the visual pathway leading to the occipital lobe
Lateral geniculate body
This structure is part of the auditory pathway, ultimately leading to the temporal lobe
Medial geniculate body
Passageway for axons between the cerebellum and midbrain
Superior cerebellar peduncle
Passageway for axons between the cerebellum and pons
Middle cerebellar peduncle
Passageway for axons between the cerebellum and medulla oblongata
inferior cerebellar peduncle
