用扫描电镜观察了七鳃鳗中肾的肾小体。鲍曼囊是沿内侧动脉紧密排列在一起的阻塞状囊。囊的侧壁相对于邻近囊的侧壁。内侧动脉的肾小球毛细血管在邻近的鲍曼囊相对壁之间呈放射状延伸。囊腔内毛细血管的膨出与囊上皮系膜褶皱有关。有足细胞的内脏层和鳞状上皮的顶层的过渡带被线性排列的杆状上皮细胞包围。尿小管的孔道上排列着带有纤毛束的细胞。
The renal corpuscle of the lamprey mesonephros was studied under the scanning electron microscope. Bowman's capsules with individual spaces are chockshaped sacs closely packed together along a medial artery. The lateral walls of the capsules are apposed to those of neighbouring capsules. Glomerular capillaries from the medial artery extend radially between the apposed walls of neighbouring Bowman's capsules. Bulgings of capillaries into the capsular space are associated with mesangial folds of the capsular epithelium. The transitional zone of the visceral layer with podocytes and the parietal layer of squamous epithelium is bounded by linearly arranged rod-shaped epithelial cells. Apertures of the urinary tubule are lined by cells equipped with a fascicle of cilia.
