The medullary cavity (medulla, innermost part) ... Intramedullary is a medical term meaning the inside of a bone.
Lateral medullary syndrome can be caused by the blockage of either the posterior inferior cerebellar artery or of the vertebral arteries. Progressive bulbar palsy (PBP) is a disease that attacks the nerves supplying the bulbar muscles.
The medullary pyramids contain motor fibers that are known as the corticobulbar and corticospinal tracts. The corticospinal tracts are on the anterior surface of the pyramids. These tracts transport motor signals that originated in the precentral gyrus and travelled through the internal capsule to the medulla oblongata and pyramids.
Medulla (Latin for "marrow") or medullary may refer to: Science. Medulla oblongata, a part of the brain stem; Renal medulla, a part of the kidney;
The medullary interstitium is the tissue surrounding the loop of Henle in the medulla. It functions in renal water reabsorption by building up a high hypertonicity , which draws water out of the thin descending limb of the loop of Henle and the collecting duct system .
The medial lemniscus, also known as Reil's band or Reil's ribbon (for German anatomist Johann Christian Reil), is a large ascending bundle of heavily myelinated axons that decussate in the brainstem, specifically in the medulla oblongata.
The cisterna magna (posterior cerebellomedullary cistern, [1] or cerebellomedullary cistern [2] [3]) is the largest of the subarachnoid cisterns.It occupies the space created by the angle between the caudal/inferior surface of the cerebellum, and the dorsal/posterior surface of the medulla oblongata (it is created by the arachnoidea that bridges this angle [3]).
The conus medullaris (Latin for "medullary cone") or conus terminalis is the tapered, lower end of the spinal cord. It occurs near lumbar vertebral levels 1 (L1) and 2 (L2), occasionally lower. [1] [2] The upper end of the conus medullaris is usually not well defined, however, its corresponding spinal cord segments are usually S1–S5.
