Document Summary
Interactive site between the central nervous system and endocrine systems. Pair of oval grey masses interconnected with most regions of the brain and spinal cord via a vast number of fibre tracts. Makes up a portion of the walls of the lateral ventricle. Connects through the middle of the third ventricle. Relay station to and from the cerebral cortex for all sensory stimuli (except the olfactory nerves) Underneath the body of the lateral ventricle. Posterior to the optic chiasm, mamillary bodies and infundibulum. Forms the floor of the third ventricle. Connects to the pituitary via the infundibulum. Contains posterior commisure tracts + pineal gland. The pineal gland sits on the roof of the midbrain just posterior to the third ventricle. Located in the sella turcica at the base of the brain. 10 of the 12 cranial nerves originate from nuclei located in brain stem. Acts as a conduit among the cerebral cortex, cerebellum and spinal cord.
