Smooth Muscle Cells of Penis in the Rat: Noninvasive Quantification with Shear Wave Elastography

Figure 2

Sections of rat’s penile tissue (HE 100x). The outer layer is the corpus cavernosum; the inner layer is the corpus spongiosum. At the center of the corpus spongiosum is the urethra (cavity) which is covered with urethral epitheliums (blue staining). The penile tissue is mainly composed of SMCs and fibroblasts and the arrangement.
