摘要: 1. Each paired ganglion of Helix pomatia is supplied by symmetrically arranged branches from the anterior aorta. Capillaries these open into a blood space which adjacent to, and continuous over surface nervous tissue. Blood passes this through epineural sheath body cavity sinuses. 2. With electron microscope three tissue layers are seen separating spaces neurons each ganglion. These (i) luminal endothelium, (ii) fibrous connective layer mainly collagen (iii) glial cells. 3. Both endothelium freely permeable to uncharged particles 100 A or less.
