Function of Nervous System. Sensory afferent neurons convey information from tissues and organs into the CNS.

1、神经系统的功能 感觉传入神经元将来自组织和器官的信息传递给CNS。

The cortical radiate arteries continue to divide eventually forming afferent arterioles that split into a tiny bundle of capillaries called the glomerulus.

小叶间动脉继续分支，最后形成入球小动脉；后者再分成若干小支形成一团微小的毛细血管球，即肾小球。

Now, so far, your body's response to the stimulus has been handled by the sensory, or afferent, division of your peripheral nervous system.

到目前为止，你身体对刺激的反应是由感觉或传入处理的，这属于你周围神经系统的分支部门。

Afferent and efferent can also refer generally to neurons which, respectively, bring information to or send information from brain region.

传入和传出神经也可以泛指分别向大脑区域传递信息或从大脑区域发出信息的神经元。

Today you got your first look at the peripheral nervous system, by learning how the afferent and efferent divisions provide information about, and responses to, pain.

今天你第一次看到了外周神经系统，通过学习传入和传出部门如何提供关于疼痛的信息和反应。

The somatic nervous system consists of afferent fibers that receive information from external sources, and efferent fibers that are responsible for muscle contraction.

躯体神经系统由接收外界信息的传入纤维和负责肌肉收缩的传出纤维组成。

When you hold a hot cup of coffee, sensory neurons in your hand transmit signal to brain through sensory neurons, also called afferent neurons, that the cup is hot.

当你拿着一杯热咖啡时，你手中的感觉神经元通过感觉神经元（也称为传入神经元）向大脑传递信号，水杯是热的。

All of that excess fluid gets pulled into the afferent lymphatic capillaries, which are closed-ended vessels found throughout the body, even the brain, which is actually discovery made in 2015.

所有剩余的液体流进传入毛细淋巴管；淋巴管是遍布全身的闭锁管道；2015年，科学家发现大脑中也存在淋巴管。

In fact, the mesangium is continuous with the smooth muscles of the afferent and efferent arterioles, and fills in the space between the loops of blood vessels, hence the name.

事实上，系膜是由入球、出球小动脉的平滑肌细胞延续而来，填满了毛细血管袢的空隙，因此得名Mes-angium。

So, in the case of hypovolemia and hypotension, the macula densa cells sense the low sodium and chloride levels and send a signal over to the juxtaglomerular cells which are located in the wall of the afferent arteriole.

因此，当血容量减少、低血压时，致密斑感受到钠、氯含量降低，传递信号给位于入球小动脉血管壁上的球旁细胞。
