Untitled Flashcards Set

Rostal

Towards the snout.

Caudal

Towards the back.

Cerebrum

Involved in movement and sensory processing.

Diencephalon

Contains thalamus, hypothalamus, and epithalamus.

Brain stem

Composed of midbrain, pons, and medulla.

Cerebellum

Functions to smooth and coordinate body movements.

Anterior Horn

Refers to the frontal region.

Posterior horn

Refers to the occipital region.

Body

Represents the parietal lobe.

Inferior horn

Corresponds to the temporal lobe.

Third Ventricle

Located in the diencephalon.

Fourth Ventricle

Found in the brain stem.

Flow of CSF

Exits lateral ventricle through interventricular foramen to third ventricle, then exits through cerebral aqueduct, fourth ventricle, and into central canal or subarachnoid space via apertures.

Deep Gray matter

Includes basal nuclei, which initiate and terminate body movement while suppressing unwanted movement.

Precentral motor cortex

Located in the frontal lobe.

Postcentral somatosensory cortex

Located in the parietal lobe.

Primary auditory cortex

Located in the temporal lobe.

Primary visual cortex

Located in the occipital lobe.

Somatotherapy

Body mapping where grooves are responsible for specific body parts; hands and face are over-represented.

Commissural fibers

Fibers that travel between hemispheres through the corpus callosum.

Associational fibers

Interhemispheric fibers connecting gyrus to gyrus.

Projection fibers

Fibers that project from high to low regions, north to south.

Thalamus

Connected by interthalamic adhesion, serves as a relay station for sensory information.

Hypothalamus

Contains nuclei such as pituitary gland, infundibulum, and mammillary body.

Epithalamus

Includes the pineal gland, which produces melatonin.

Midbrain

Contains the cerebral peduncles, cerebral aqueduct, and corpora quadrigemina.

Cerebral Peduncles

motor tracts in the midbrain that connect the cerebrum to the spinal cord and cerebellum

Cerebral aqueduct

A passage that runs through the center of the midbrain.

Corpora quadrigemina

dorsal midbrain; superior colliculi for visual reflexes and inferior colliculi for auditory reflexes.

Pons

Acts as a bridge between the brainstem and cerebellum.

Middle cerebellar peduncle

Contains motor axons from the pons to the cerebellum.

Medulla Oblongata

Regulates homeostasis.

Pyramids

Motor tracts containing the same axons as the cerebral peduncles.

Olives

Nucleus involved in sensory replay.

Motor decussation

Area where motor information crosses over.
