Like other smooth muscles, smooth muscle cells of the prostate lack the striations characteristic of skeletal and cardiac muscle cell. Functionally, they play a crucial role in reproductive and urinary functions. Smooth muscle cells of the prostate contribute to the transport and expulsion of prostatic secretions into the urethra and respond dynamically to signaling molecules such as hormones and neurotransmitters. For instance, under sympathetic nervous stimulation, they contract and apply pressure on the gland's ducts, facilitating the secretion process.
