| Because most medullary raphe neurons that project to motoneurons are inhibited by vagal afferents. |
| As it grew, this bone was replaced in the medullary cavity through processes of erosion and redeposition. |
| Each trochlear nerve makes its exit through the caudal tectum, immediately lateral to the frenulum of the superior medullary velum. |
| The glomerular tufts were shrunken or necrotic and renal medullary rays were congested. |
| The interfollicular area and medullary cords were heavily infiltrated by mature plasma cells with a sheetlike arrangement in some areas. |
| Microscopy revealed acellular laminated membranes with a germinal layer within the medullary cavity of the tibia and fibula. |
