神经系统和内分泌系统之间的差异

March 3, 2012Posted by纳文

这关键区别在神经系统和内分泌系统之间nervous system uses electrical action potentials along the neurons to transmit signals to the target body parts while the endocrine system uses chemicals called hormones along the bloodstream to send signals to the target cells and organs.

Nervous system and endocrine system are the two main organ systems of our body that are responsible for the regulation of all the activities within the body. These systems facilitate the communication between cells, tissues and organs. Also, they use different mechanisms for this purpose. That is, the nervous system uses electrical signals or nerve impulses to transmit signals while the endocrine system uses chemicals such as hormones to send signals to the target body parts. Furthermore, the nervous system consists of a network of nerve cells. Whereas, the endocrine system consists of a set of glands.

What is Nervous System?

Nervous system is one of the major organ systems of the organisms, which is responsible for the coordination of biological activities inside the body. It consists of a network of specialized cells called neurons. There are two major parts of the nervous system namely thecentral nervous system (CNS) and the peripheral nervous system (PNS)。In vertebrates, the CNS comprises brain, spinal cord, and retina while the PNS includes the sensory neurons, ganglia, and connecting neurons.

尽管神经元没有彼此的身体联系,但它们的相互作用以高度复杂的方式发生,以有效地传递到身体的所有部位。在神经系统作用过程中,电化学波或脉冲会通过神经途径产生并传播神经元,以触发必要的动作。神经系统使用称为神经递质的化学信使将信号从一个神经元传递到下一个神经元。有些人可以控制一些神经活动,而有些则是自主的。

神经系统是脊椎动物中最复杂的系统之一,但是一些较低的分类单元(例如Cnidaria)只有一个简单的神经系统。Placozoans和Mesozoans甚至没有神经系统,但存在其他信号传递手段。人类神经系统是世界上所有其他动物中最大的大脑最大的发达。神经系统是人类从大自然中收到的伟大礼物之一。

What is Endocrine System?

Endocrine system is a discrete set of glands that secrete different types of hormones to the circulatory system in order to regulate the functions of the body. Each gland of the endocrine system is responsible for the secretion of different hormones, and those hormones trigger different activities in different places in the body.Hypothalamus,,,,pineal body,,,,前后垂体,肾上腺和甲状腺是内分泌系统的主要腺体,而还有其他一些相关的腺体。

相关的内分泌腺位于肾脏,消化系统,性腺和其他一些地方。关于内分泌系统的有趣事实是它是一个化学信息系统。生长和发育,代谢和脾气是内分泌系统调节的主要功能。内分泌系统激素的作用缓慢但持久。这些激素的延长功能有时可能持续大约两个星期,但是从分泌之时起启动功能的时间可能会长达两个小时。

What are the Similarities Between Nervous System and Endocrine System?

  • 神经系统和内分泌系统都将信号传输到目标器官。
  • 这y are important organ systems.
  • 神经系统和内分泌系统促进细胞之间的通信。
  • 两者都使用化学信使。

神经系统和内分泌系统有什么区别?

我们体内有不同的器官系统。其中,神经系统和内分泌系统是两个重要的器官系统。两种系统都涉及整个身体部位的信号传输以调节不同的活动。但是,神经系统由神经元网络组成,而内分泌系统由几个腺体组成。这是神经系统和内分泌系统之间的一个区别。神经系统和内分泌系统之间的主要区别在于,通过电力电位的手段,神经系统通过称为激素的化学物质将信号发送到靶器官,内分泌系统将信号发送到靶细胞和组织。此外,神经元有助于传输信号,而血液有助于将激素运输到目标位置。神经系统和内分泌系统之间的另一个区别是,神经系统的作用是立即的,而内分泌系统的作用很慢。

以下信息图介绍了有关神经系统和内分泌系统之间差异的更多详细信息。

Summary – Nervous System vs Endocrine System

神经系统具有神经元,而内分泌系统具有几个不同的腺体。这两个系统对于调节身体活动都很重要。神经元和神经递质促进神经冲动在神经系统中的传播。另一方面,涉及内分泌系统信号传输的循环系统传播的激素。神经系统的作用很快,但在长时间内持续不止。相比之下,内分泌系统的作用很慢,但长时间仍然存在。这是神经系统和内分泌系统之间的区别。
