Untitled Flashcards Set

Rostal: Towards the snout

Caudal: Towards the back

Cerebrum: movement and sensory 

Diencephalon: thalamus, the hypothalamus, and the epithalamus.

Brain stem: midbrain, pons, and medulla

Cerebellum: smooths and coordinates body movements 

Anterior Horn: frontal 

Posterior horn: occipital 

Body: parietal lobe 

Inferior horn: temporal 

Third Ventricle: diencephalon 

Fourth Ventricle: Brain Stem 

Flow of CSF: Exits Lateral ventricle through interventricular foramen →  third ventricle exits through cerebral aqueducts →  fourth ventricle→ central canal or subarachnoid space through apertures

Deep Gray matter: Basal nuclei, initiates and terminates body movement and suppresses unwanted movement

Precentral motor cortex- frontal lobe 

Postcentral somatosensory cortex- parietal 

Primary auditory cortex- temporal 

Primary visual- occipital

Somatotherapy: Body mapping, grooves are responsible for that body part. Hands and face are over-represented

Commissural fibers: travel between hemispheres through corpus callosum  

Associational fibers: interhemispheric, gyrus to gyrus 

Projection: north to south, somewhere high to low

Thalamus: connected by interthalamic adhesion or indeterminate mass, sub nuclei serve as a relay station as the first stop 

Hypothalamus: contains pituitary gland, infundibulum and mammillary body: paired nucleus 

Epithalamus: pineal gland, melatonin and 

Midbrain: Cerebral peduncles, cerebral aqueduct and corpora quadrigemina

Cerebral Peduncles: motor axons connecting cortex to cerebellum and spinal cord 

Cerebral aqueduct: passes through center of midbrain

Corpora quadrigemina: four bumps on dorsal midbrain, superior colliculi: visual reflexes, inferior colliculi: auditory reflexes 

Pons: bridge between brainstem and cerebellum 

Middle cerebellar peduncle: motor axons from pons to cerebellum

Medulla Oblongata: homeostasis

Pyramids: motor tracts, same axons as the cerebral peduncles

Olives: nucleus that is involved in sensory replay

Motor decussation: area where motor info crosses
