这些神经细胞通过脊髓向肌肉发送信号，使我们具备运动的能力。

These send signals through the spinal cord to the muscles to give us the ability to move.

这种细胞被发现存在于初成形的胚胎中，但它很快发生变化，转变成各种类型的细胞，诸如肌肉细胞、神经细胞、皮肤细胞或血细胞。

These cells are found in days-old embryos, but quickly differentiate -- becoming the various cell types from muscle to nerve to skin or blood.

钙也是必不可少的细胞结构，肌肉收缩，神经传递，酶激活和激素功能。

Calcium is also essential from cellular structure, muscle contraction, nerve transmission, enzyme activation and hormone function.

The cells that take an electrical signal, which is coming down your nerve and convert it into a muscle contraction work this way, so 'neuro' nerve, muscle junctions act based on ligand-gated ion channels.

依靠相同的工作原理,细胞将来自于神经的,电信号传递到细胞收缩肌中,所以神经和肌肉关节运动,都基于配体门控离子通道

So organs are made up of combinations of tissues where all the tissues are collections of cells that are doing some function, nervous tissue, muscular tissue, epithelial tissue, those are examples of tissues that form organs.

所以器官是由各种组织组合而成,所有的组织都是,具有某些功能的细胞集合,神经组织,肌肉组织,上皮组织,这些都是由组织构成器官的例子
