What Nerves Are Responsible for Controlling the Muscles at the Base of the Penis?
What Nerves Are Responsible for Controlling the Muscles at the Base of the Penis? What Nerves Are Responsible for Controlling the Muscles at the Base of the Penis? The nerves responsible for controlling the muscles at the base of the penis are branches of the Pudendal Nerve—specifically the Deep Branch of the Perineal Nerve—which provides […]
What Is the Difference Between Somatic and Autonomic Innervation of the Penis?
What Is the Difference Between Somatic and Autonomic Innervation of the Penis? What Is the Difference Between Somatic and Autonomic Innervation of the Penis? The difference between somatic and autonomic innervation of the penis is their fundamental role: the somatic system (Dorsal Nerve) handles conscious sensation and motor function (ejaculation), while the autonomic system (Cavernous […]
What Is the Pathway for the Dorsal Nerve of the Penis?
What Is the Pathway for the Dorsal Nerve of the Penis? | FactBasedUrology What Is the Pathway for the Dorsal Nerve of the Penis? The pathway for the Dorsal Nerve of the Penis is a complex neurological route that originates from the sacral plexus (S2-S4) in the lower spine, travels through the Pudendal Canal (Alcock’s […]
How Do Autonomic Nerves Control Blood Flow to the Penis?
How Do Autonomic Nerves Control Blood Flow to the Penis? | FactBasedUrology How Do Autonomic Nerves Control Blood Flow to the Penis? Autonomic nerves control blood flow to the penis through a delicate balance between the sympathetic nervous system, which maintains flaccidity by constricting arteries, and the parasympathetic nervous system, which triggers erection by dilating […]
What Is the Role of the Pudendal Nerve in the Male Reproductive System?
What Is the Role of the Pudendal Nerve in the Male Reproductive System? What Is the Role of the Pudendal Nerve in the Male Reproductive System? The role of the pudendal nerve in the male reproductive system is to function as the primary somatic command center, providing the sensory input from the penis that triggers […]
What Is the Main Nerve Responsible for Penile Sensation?
What Is the Main Nerve Responsible for Penile Sensation? What Is the Main Nerve Responsible for Penile Sensation? The main nerve responsible for penile sensation is the Dorsal Nerve of the Penis, a terminal branch of the Pudendal Nerve that provides somatic (conscious) sensory innervation to the skin and especially the glans penis. This nerve […]
How Does Blood Flow Differ Between the Flaccid and Erect States?
How Does Blood Flow Differ Between the Flaccid and Erect States? | FactBasedUrology How Does Blood Flow Differ Between the Flaccid and Erect States? Blood flow differs fundamentally between the flaccid and erect states based on vascular resistance: the flaccid state is a high-resistance, low-flow maintenance mode controlled by the sympathetic nervous system, while the […]
What Is the Vascular Pathway for Blood Flow into the Penis?
What Is the Vascular Pathway for Blood Flow into the Penis? What Is the Vascular Pathway for Blood Flow into the Penis? The vascular pathway for blood flow into the penis begins at the abdominal aorta, travels through the internal iliac and internal pudendal arteries, and terminates by branching into the cavernosal, dorsal, and bulbourethral […]
What Are the Primary Veins of the Penis?
What Are the Primary Veins of the Penis? | FactBasedUrology What Are the Primary Veins of the Penis? The primary veins of the penis are classified into two distinct systems based on their depth relative to Buck’s fascia: the superficial dorsal vein, which drains the skin, and the deep dorsal vein, which drains the erectile […]
How Is Blood Drained from the Corpora Cavernosa?
How Is Blood Drained from the Corpora Cavernosa? How Is Blood Drained from the Corpora Cavernosa? Blood is drained from the corpora cavernosa through a specialized system beginning at the sub-tunical venular plexus, exiting via emissary veins, and primarily converging into the deep dorsal vein of the penis. Unlike standard circulatory pathways where flow is […]
