Octopus Chokes Dolphin to Death in First-Ever Discovery
The young male, Gilligan, was in otherwise perfect condition, a new study
says.
Nobody ever told Gilligan the dolphin not to bite off more than he could
chew.
The male Indo-Pacific bottlenose dolphin is the first known cetacean to die
from asphyxiation by octopus, a new study says.

Technically I think this time you are in lower larynx position and
better vocal chord support and more relaxed facial muscle. Those
are good. Maybe a little bit tense and a little bit overdo on
lower larynx position, but I am not sure.
I am switching Sony MDR-V700 to Sennhensier HD280Pro. MDR-V700
has somewhat too much lower end while HD280Pro has somewhat too
less high end. I need re-adjust my ear ... No perfect Monitor

Hoarseness is generally caused by irritation of, or injury to, the vocal
cords. T
Hoarseness can be caused by a number of conditions. The most common cause of
hoarseness is acute laryngitis (inflammation of the vocal cords) caused by
an upper respiratory tract infection (usually viral), and less commonly from
overuse or misuse of the voice (such as from yelling or singing).
Other causes of hoarseness include:
benign vocal cord nodules or polyps,

allergies,

也说汉语的“词汇量”
长期以来,汉语不但以难学著称,而且还常常被指责为词汇欠缺、表达贫乏。生为汉人
,真可谓双倍之不幸——语言学习所需的时间本来就已经比别人多了好几倍,不料最终
学到的东西还不及人家几分之一。
毛喻原先生便为这种论点提供了具体数据:“我们知道,汉语一部普通的《新华字典》
所收单字(含繁体、异体)是一万一千一百个左右,清初所编的《康熙字典》所收汉字
是四万七千多个,最近出的《汉语大字典》所收汉字也才五万六千个。与英语相比,汉
语的词汇量是非常小的。即使一部欧美普通学生所用的字典所收单词也至少在十六至十
七万个以上。如著名的《牛津字典》所收单词是六十多万个。篇幅最大的《韦伯斯特大
词典》所收单词几乎达到一百万之多。仅从词汇量来比较,汉语和英语在这方面的差别
是非常巨大的。”
显然,毛先生“汉语词汇量非常小”这一结论,是用“科学方法”计算出来的,即:拿
英语单词总量减去汉字字数总量。显然,这么简单的题目,连小学生都难不倒,根本用
不着毛先生亲自动手。不过,小学生同时还知道,加减法的运算有一个先决条件,即“
单位”必须相等。例如,五匹马与四头牛就不好相加;七颗白菜减三根萝卜也不... 阅读全帖

有可能是irritable larynx symdrome.就是喉咙收了刺激以后,对外界的反应会特别敏
感,导致irritation,从而导致想咳嗽。是一个恶性循环。
要多喝水,吞咽有异物感可能是因为喉咙干燥引起的。要是咳嗽咳不出东西出来的话,
就尽量不要咳嗽。喉咙痒的时候吞口水代替咳嗽。这样坚持一个星期,应该可以停止咳
嗽。
喉咙不痛得厉害的话就不需要吃消炎药。要是过一段时间还不好的话,建议你找个ENT
看看喉咙有没有问题。

要证明进化论,最为形象的例子不是你同桌长得像大猩猩,而是我们脖子里那条迂回曲
折的“喉返神经(recurrent laryngeal nerve, RLN)”。喉返神经是大脑控制咽喉运
动的神经,我们说话和吞咽都离不开它。这喉返神经行走不易:它从脑干伸出来,放着
直达咽喉的近路不走,偏要往下延至心脏,绕过主动脉再折返回来。这一招曲线救国不
可不谓“扣人心弦”:

绕过心脏后才能到达喉部,控制喉部肌肉完成吞咽动作。
喉返神经:进化出的弯路
如若人真是造物主所造,喉返神经当属其最糟糕的手笔。当然啦,人并不是凭空设计出
来,而是从远古的祖先进化而来。不仅如此,我们身上各个... 阅读全帖

看到后面的那个链接,终于明白你在说什么了。
我还以为你很专业呢,你怎么也不研究一下就人云亦云呀。
-    声明一下,不是我译的。不过,就算“心脏”错用在“aortic arch”,对全
文无伤大雅。
vagus nerve 到 aortic arch 那里分叉,分出一条recurrent laryngeal nerve,正好
在主气管的下端,由下往上,控制颈部肌肉。有什么问题吗?
你贴的那个文章一开头就错了,什么绕过心脏,明明是在主动脉那里分出的支神经,你
最好量量看有多长,再决定是不是绕了弯路,可别把vagas nerve也一块儿量进去了。
我估计你贴的文章里就把vagas nerve也当recurrent laryngeal nerve算了。
-   有问题,recurrent laryngeal nerve 的 nucleus (nuclei) 在哪里?
superior laryngeal nerve 在哪里从 vagus nerve 分叉处来的?同是通向 larynx,
为什么一条直接连接,另外一条拐了一个弯?recurrent laryngeal nerve 是控制“颈
