The root of the penis is the most proximal part of the penis. It is located in the urogenital triangle of the perineum, where it is fixed to the pubic symphysis via the two suspensory ligaments of the penis.The root consists of the two muscles (ischiocavernosus and bulbospongiosus muscles) and proximal expansions of the erectile tissues; the two crura of penis and the bulb of penis.

6. Ganglion cell fiber layer. The ganglion cell axons run in the nerve fiber layer above the inner limiting membrane towards the optic nerve head in a arcuate form (Fig. 00, streaming pink fibers). The fovea is, of course, free of a nerve fiber layer as the inner retina and ganglion cells are pushed away to the foveal slope.

To continue with the analogy of the circuit diagram, there are three different types of "junctions" that operate within the sympathetic system ().The first type is most direct: the sympathetic nerve projects to the chain ganglion at the same level as the target effector (the organ, tissue, or gland to be innervated). An example of this type is spinal nerve T1 that synapses with the T1 ...

Unlike other nerves of the body that are myelinated by Schwann cells, the fibers of the optic nerve are myelinated by oligodendrocytes. Arising from the posterior pole of each eye, each optic nerve is about 35 mm and 55 mm in length and can be subdivided as follows: The optic nerve head. The intraorbital part. The intracanalicular part.
