What Are Lateral Ventricles?
It is located in the deep part of the cerebral hemisphere, one on the left and one on the right. It has a "C" -shaped ventricular cavity lined with the ventricular membrane, and the cavity is filled with cerebrospinal fluid. The two ventricles are separated by the median sagittal boundary plate, which is called the transparent septum. Each ventricle passes through the interventricular foramen and leads to the third ventricle, so it is also indirectly communicated. Each ventricle includes a central portion located in the parietal lobe and anterior, posterior, and inferior horns extending to the frontal, occipital, and temporal lobes. The lateral ventricle choroid plexus is attached to the back of the dorsal thalamus, connected forward through the interventricular foramen and the third ventricle choroid plexus, backwards around the dorsal thalamus through the lateral accessory triangle, and then turns forward and downward, and the coastal horse umbrella extends to the front of the lower corner .

Lateral ventricle anatomy
- It is the cavity in the cerebral hemisphere, containing the cerebrospinal fluid. It is divided into the following four parts, and communicates with the third ventricle by interventricular foramen.
Lateral ventricle anatomy
- Central part: located in the parietal lobe above the thalamus, below the corpus callosum, is the part of the ventricle extending to the pressure part, containing a part of the choroid plexus. The apex of the central part is composed of the corpus callosum, and the bottom of the chamber is in turn the caudate nucleus, the terminal striae, the attachment plate on the back of the dorsal thalamus, the choroid plexus, and the fornix. The part where the central part of the lateral ventricle merges with the posterior and inferior horns is called the lateral collateral triangle. The morphological changes of this triangle are of great significance in the diagnosis of lateral ventricle angiography.
- Anterior angle: the forward part of the interventricular foramen, the inside of which is a transparent septum, the outside is the caudate nucleus, the upper part is the trunk of the corpus callosum, and the front reaches the corpus callosum. The anterior angle extends forward from the plane of the interventricular hole, and the corpus callosum forms its top and anterior wall; the caudate nucleus forms its bottom and outer walls; a transparent spacer is between the corpus callosum and the fornix, separating the anterior angles on both sides. The length of the posterior horn varies, and the fibers of the carcass blanket form its dorsal and outer sidewalls, and the bottom surface is the occipital medulla; there is a longitudinal bulge on the inner sidewall, that is, the pitch of the bird, which is deeply subsided by the sulcus groove.
- Posterior angle: from the center to the back, reaching into the occipital lobe. Slightly narrow into the occipital lobe. The carcass blanket constitutes its top and outer walls; the inner wall is composed of two longitudinal bulges: the dorsal bulge is called the posterior corner kick, which is composed of fibers from the corpus callosum to the occipital lobe; Made. The bottom is composed of the occipital medulla.
- Bottom corner: located on the dorsal outer side of the hippocampus, containing the choroid plexus. The inferior angle starts from the lateral para-triangle, loops down the dorsal thalamus, and extends forward into the medial part of the temporal lobe. Its bottom surface is directly connected to the bottom of the rear corner, and there is a significant side auxiliary bulge on the bottom, which is caused by the sunken side auxiliary groove. The top and outer walls are mostly formed from a blanket, and the inner part of the top is formed from a small part of the caudate nucleus and the accompanying terminal lines. The most prominent structures on the lower wall are the hippocampus and the hippocampus. The lateral ventricle choroid plexus is attached to the back of the dorsal thalamus, and the anterior interventricular foramen is continuous with the choroid plexus of the third ventricle. It passes back through the lateral accessory triangle around the dorsal thalamus and then turns forward and downward. Lower corner front.
