阴茎的正确标签 阴茎是男性生殖系统的外部器官，具有两个主要功能：性交和排尿。本文将探讨阴茎的结构和功能，以及这些结构如何导致某些临床条件。 阴茎可以分为三个部分： 根 – 最近的部分，固定阴茎的阴茎头体。它位于骨盆底面的浅表皮下袋中，外部不可见。根包括三个勃起组织（左右两条背静脉和阴茎球）。还有两个肌肉（坐骨海绵状肌和球海绵状肌）。 躯干 – 在根和阴茎头之间的自由阴茎部分。它悬挂在耻骨联合上。由三柱勃起组织组成 – 左右两个圆柱。 阴茎头 – 阴茎的最远端部分。它是从阴茎球部远端扩张形成的圆锥形。它包含尿道开口，称为阴茎头孔。 阴茎的血管化 阴茎由三个主要的血管源供血： 阴茎背动脉 阴茎深动脉 阴茎球部动脉 这些动脉都是内骨盆动脉的分支。这些动脉起源于骨盆内动脉的前支。 静脉血液从阴茎排出是通过成对的静脉。阴茎的勃起空间由阴茎深静脉引流 – 这个静脉流入前列腺静脉丛。浅表静脉则引流阴茎的浅表结构，如皮肤和组织。 阴茎的感觉神经支配 阴茎由S2-S4脊髓段和脊神经节提供感觉和交感神经支配。阴茎和阴茎头的皮肤和阴茎头由阴茎背神经支配，这是骨盆神经的分支。 阴茎的相关临床意义 包茎和阴茎弯曲 包茎 包茎是一种情况，包皮紧贴阴茎头部，无法回缩。这种情况可能是先天性的，但也可以由于阴茎皮肤发炎和收缩而在成年后发生。它可能导致局部刺激，因为积累的精液（阴茎皮肤产生的油性分泌物）或甚至为感染敞开大门。 主要缺点是无法进行局部卫生——未经治疗的包茎甚至与阴茎癌相关联。 阴茎下弯畸形 阴茎下弯是一种急性情况，当一个紧绷的包皮被拉到阴茎头上时会发生——这可能导致软包皮水肿，并进一步绞痛。 阴茎的功能障碍 勃起功能障碍 勃起功能障碍是指无法维持勃起的能力。这是一个常见的情况，可能有多种原因，最常见的是血管原因（如高血压、高胆固醇、吸烟或糖尿病）。心理原因包括焦虑和抑郁。 治疗基于原因。最常见的药物是PDE5抑制剂，在阴茎海绵状体的水平上失活酶磷酸二酯酶5，放松阴茎海绵状体和血管的平滑肌纤维。这样，就可以实现更好的动脉血流。 阴茎持续勃起 阴茎持续勃起是一种严重情况，即使没有性刺激也会持续存在。这通常疼痛，并且是由于血液被困在阴茎的勃起组织中，没有动脉血流。 如果持续超过四个小时的阴茎持续勃起，则是一个医疗紧急情况：如果不治疗，可能会导致阴茎组织瘢痕化并永久性勃起功能障碍。 阴茎的解剖学和生理学 阴茎是一个具有生殖和排尿功能的男性动物的外生殖器官。与许多其他物种不同，人类的阴茎没有骨盆骨，而是完全依赖于血管充血来实现勃起。人类阴茎不能退缩到腹股沟中，而且比任何其他灵长类动物的阴茎都大，特别是在与其身体质量的比例方面。 人类阴茎是什么样？ 这是一个人类阴茎的示意图，标有各部分位置。
