Location of infarct Presentation Pure motor stroke/hemiparesis (most common lacunar syndrome: 33–50%) posterior limb of the internal capsule, basilar part of pons, corona radiata It is marked by hemiparesis or hemiplegia that typically affects the face, arm, or leg of the side of the body opposite the location of the infarct.
Section parallel to the surface from the body of the femur. X 100. a, Haversian canals ; b, lacunae seen from the side; c, others seen from the surface in lamella , which are cut horizontally. Nucleated bone cells and their processes, contained in the bone lacunae and their canaliculi respectively.
There are usually three lacunae on either side of the sinus: a small frontal, a large parietal, and an occipital, intermediate in size between the other two. [ citation needed ] Most of the cerebral veins from the outer surface of the hemisphere open into these lacunæ, and numerous arachnoid granulations (Pacchionian bodies) project into them ...
The caudate nuclei are near the center of the brain, sitting astride the thalamus. There is a caudate nucleus in each hemisphere of the brain. Each nucleus is C-shaped, with a wider "head" (caput in Latin) at the front, tapering to a "body" (corpus) and a "tail" (cauda). Sometimes a part of the caudate nucleus is called the "knee" (genu).

In neuroanatomy, the lateral geniculate nucleus (LGN; also called the lateral geniculate body or lateral geniculate complex) is a structure in the thalamus and a key component of the mammalian visual pathway. It is a small, ovoid, ventral projection of the thalamus where the thalamus connects with the optic nerve. There are two LGNs, one on the ...
Receptors are located throughout the body including the skin, epithelia, internal organs, skeletal muscles, bones, and joints. The cutaneous receptors of the skin project in an orderly fashion to the spinal cord , and from there, via different afferent pathways ( dorsal column-medial lemniscus tract and spinothalamic tract ), to the ventral ...
The granulations are often situated near where cerebral veins drain into the dural sinuses. They are most prominent along the superior sagittal sinus, particularly those lodged within the lateral lacunae.
