adrenal medulla the inner portion of the adrenal gland, where epinephrine and norepinephrine are produced.
medulla of bone bone marrow.
medulla oblonga´ta that part of the hindbrain continuous with the pons above and the spinal cord below; it houses nerve centers for both motor and sensory nerves, where such functions as breathing and the beating of the heart are controlled. See also brain.
medulla os´sium bone marrow.
renal medulla the inner part of the substance of the kidney, composed chiefly of collecting tubules, and organized into a group of structures called the renal pyramids.
medulla spina´lis (medulla spina´lis) spinal cord.
medulla of thymus the central portion of each lobule of the thymus; it contains many more reticular cells and far fewer lymphocytes than does the surrounding cortex.

adrenal medulla
the inner portion of the adrenal gland, where epinephrine is produced.
medulla of bone
bone marrow, contained in the medullary canal of bone.
medulla oblongata
that part of the hindbrain continuous with the pons anteriorly and the spinal cord posteriorly; it houses nerve centers for both motor and sensory nerves, where such functions as breathing and the beating of the heart are controlled. Called also myelencephalon. In animals the principal clinical manifestations of local lesions in the medulla are those of head rotation and circling, and facial and tongue paralysis with resulting difficulty in prehension and swallowing. With diffuse lesions spastic paralysis or a stiff-legged incoordination occurs.
medulla ossium
bone marrow.
renal medulla
the inner part of the substance of the kidney, composed chiefly of collecting tubules, and in some species organized into a group of structures called the renal pyramids.
spinal medulla, medulla spinalis
spinal cord.
medulla of thymus
the central portion of each lobule of the thymus; it contains many more reticular cells and far fewer lymphocytes than does the surrounding cortex.
