Each consists of a thin connective tissue capsule enclosing a core of homogeneous or nucleated semifluid substance. As the nerve-fibre pierces the capsule, it loses its medullary sheath, and the axis cylinder is con- tinued into the core of the bulb where it may pursue a somewhat tortuous course, but more fre- quently divides into minute varicose fibrils which form an intricate plexus.

The end bulbs of the glans penis and glans clitoridis are named genital corpuscles and differ from those just described in Fig. 741.— Grandrt's Corpuscles from that they are larger and possess thicker capsules. the Duck's Tongue (Izquiardo) (From Quain's Anatomy.) A, composed of three cells with two inter-. posed discs, into which the axis those of the fingers. Similar endings, termed articular lulls, are found in the synovial membranes of certain joints, cylinder of the nerve-cell is observed to pass. In B there is but one tactile disc enclosed between two tactile cells. (2) Corpuscles of Grandry (Fig. 741).—These are seen in the skin covering the beaks of aquatic animals, and in the mucous membrane of the duck's palate. Each consists of two or more flattened epithelial cells enclosed within a capsule, and the axis cylinder ends in flattened " tactile discs " which lie between the cells. (3) Corpuscles of Pacini (Fig. 742).—These are widely distributed and consist of small oval bodies which measure from 2 to 3 mm. in length and about 1 mm. in width. They are found on the cutaneous nerves of the hand and foot, on the infra- orbital and intercostal nerves, on the cutaneous nerves of the neck, nipple, and mamma, and on the nerves of the solar plexus. They are present in the parietal peritoneum and on the nerves of the joints, and are very plentiful in the mesentery. Please note that these images are extracted from scanned page
