Abstract:
The arteries of 5 human brainstems were injected by using a mixture of preparedchinese ink and gelatin.The capillary densities of 20 various nuclei and tracts inthe medulla oblongata were observed and measured in 300?m and 150?m serial trans-verse sections.The tracts are less vascularized than nuclei.The nuclei have been divided intohigh,medium and low three groups according to their capillary densities.The highdensity nuclei consist of accessory cuneate nucleus,inferior olivary nuclear complex,medial vestibular nucleus,nucleus cuneatus.The medium density nuclei are lateralreticular nucleus,nucleus supraspinalis,hypoglossal nucleus and nucleus gracilis.Thelow density nuclei are dorsal vagal nucleus,spinal trigeminal nucleus,nucleus ofsolitary tract.The pyramidal tract has the lowest density among the tracts observed.
