Association Fibers (Connect different parts of the same Hemisphere)

Projection Fibers (Ascend to the cortex from lower regions, projects sensory information from the cerebral cortex and sends out motor instructions.)

Term
Diencephalon Structures
Definition

Epithalamus - Pineal Gland

Thalamus - Paired, relay centers for non smell sensory stimuli, response to pain

Hypothalamus - Pituitary Gland, Infundibulum

CN IV (Trochlear Nerve)

Substatntia Nigra (Linked to basal ganglia)

Red Nucleus (Linked to cerebellum)

Term
Metencephalon Structures
Definition

Pons - Pontine Nuclei, fiber tracts to cerebellum and mesencephalon.

Internal Pons - Nuclei related to chewing and sensory sensation of head.  Respiratory control centers.

Cerebellar Peduncles (Superior, middle and inferior)

Cerebellum (Folia and Sulci (Rises and dips), Vermi.  Coordinates skeletal muscle contractions.
