Fourth ventricle
|
Part of the ventricular system of the brain, forming a single large irregularly shaped cavity located on the midline of the rhombencephalon, between the medulla, pons and the isthmus ventrally and the cerebellum dorsally. It is continuous with the cerebral aqueduct anteriorally and the central canal of the spinal cord posteriorly. It communicates with the subarachnoid space through its lateral and median apertures.

|
lateral recess of fourth ventricle
|
The lateral recess is a projection of the fourth ventricle which extends into the inferior cerebellar peduncle of the brainstem. The lateral aperture, an opening in each extremity of the lateral recess, provides a conduit for cerebrospinal fluid to flow from the brain's ventricular system into the subarachnoid space.

tela choroidea of fourth ventricle
|
Tela chorioidea that lines the fourth ventricle[ZFA]. The tela chorioidea of the fourth ventricle is the name applied to the triangular fold of pia mater which is carried upward between the cerebellum and the medulla oblongata. It consists of two layers, which are continuous with each other in front, and are more or less adherent throughout: The posterior layer covers the antero-inferior surface of the cerebellum. The anterior layer is applied to the structures which form the lower part of the roof of the ventricle, and is continuous inferiorly with the pia mater on the inferior peduncles and closed part of the medulla[WP].

|
sulcus limitans of fourth ventricle
|
In the floor of the fourth ventricle, the sulcus limitans separates the cranial nerve motor nuclei (medial) from the sensory nuclei (lateral). In the superior part of the rhomboid fossa, it corresponds with the lateral limit of the fossa and presents a bluish-gray area, the locus ceruleus (which owes its color to an underlying patch of deeply pigmented nerve cells, termed the substantia ferruginea).
