Talk:Reflex

From Wikipedia, the free encyclopedia

In the remark about Pavlov, conditional reflex is correct - please do not change it to conditioned reflex. seglea 00:45, 1 Dec 2003 (UTC) (Professor of Psychology, PhD, umpteen other letters after name, etc, etc - look, I know what I'm talking about on this one).

[edit] Physiology

The physiology of reflexes is a key factor missing from this article. It would be greatly appreciated if an expert on the topic could put in necessary information. —Preceding unsigned comment added by 59.101.89.179 (talk) 15:22, 1 June 2008 (UTC)

[edit] Out of date definition

In medicine, a reflex a.k.a. a reflex action is an involuntary reaction of the body to a stimulus. It is performed in consequence of an impulse or impression transmitted along afferent nerves to a nerve center, from which it is reflected to an efferent nerve, and so calls into action certain muscles, organs, or cells.

[edit] grasping reflex?

It's mentioned on [1], but I don't know what is it. Samohyl Jan 16:36, 25 May 2005 (UTC)

[edit] What does it mean?

On my doctors progress notes, he states that my reflexes are +2(in regards to my "knee-jerk" reaction), and that my plantar reflexes are down. I am wondering both what the "+2" could mean, and what does it mean if my reflexes are down? How exactly does the rating scale work?

[edit] Reflex in linguistics?

I was looking for what reflex meant in linguistics, but I didn't find it here... can someone point me to the article? -Iopq 03:07, 13 November 2005 (UTC)

As cognate is to cousins or sisters, so reflex is to daughters or granddaughters. If a sound or form A in a daughter language is described as a reflex of sound or form B in a parent language, then A is the sound or form that B became. For example, English initial "h" is a reflex of PIE kʷ. Does that help? 207.245.124.66 15:39, 15 February 2006 (UTC)
It would be nice if you could elaborate it on reflex (linguistics). Samohyl Jan 18:39, 15 February 2006 (UTC)
Iopq, do you mean like in reflexive verb or reflexive pronoun, perhaps? 74.141.161.180 00:56, 10 October 2007 (UTC)

[edit] is it just me or is that picture way to small to be readable?

unless you have a mac and can zoom in thats like.... completely unreadable

[edit] Autonomic Nervous system

I recall there being exceptions to the rule that the autonomic nervous system is entirely involuntary.


You're right. The enteric nervous system is the big exception as I recall. Robotsintrouble 14:08, 4 November 2006 (UTC)
I thought it was involuntary although we can influence it through cognitive actions (e.g. you can control your respiratory rate) and through psychological conditioning (salivating/production of gastric juices when you see appetising food (enteric nervous system) etc). Our control over the autonomic nervous system should be included in the article i think.

[edit] Merger?

Should this article be merged into reflexology or is it different enough to warrant its own article? NorthernThunder 03:56, 16 December 2006 (UTC)

I'd oppose merge, reflexology is more of a massage technique. A reflex action is different. Robotsintrouble 08:41, 17 December 2006 (UTC)

[edit] Are learned reflexes mediated by a reflex arc?

According to the article

A reflex action or reflex is a biological control system linking stimulus to response and mediated by a reflex arc.

Is it true also for learned reflexes that they are mediated by a reflex arc, or rather only for built-in ones? If the latter is the case, then the sentence in the article should be fixed. --Dan —The preceding unsigned comment was added by 62.245.110.111 (talk) 11:42, 1 March 2007 (UTC).

[edit] Learned or learnt?

If the former, please, revert the well-meant but incorrect edit from 29 May 2007 by User:87.113.77.216 (contribs). (“Reflexes can be built-in or learnt.”) His only other contribution to Wikipedia happens to be wrong. Personally, I don’t know.

Both are technically correct, although 'learnt' is a bit idiosyncratic in American circles, much like spilled/spilt. Amazinrick 04:50, 30 October 2007 (UTC)

[edit] Hiccups?

Are Hiccups examples of human reflexes and should be included in the list on this page? I'm not an expert but thought there might be a case... --Les

[edit] Sex

Someone vandalised by writing Sex a bunch of times. I deleted it. I'm proud of myself. You can thank me if you like.

thasexnk you! —Preceding unsigned comment added by 59.101.89.179 (talk) 14:42, 1 June 2008 (UTC)

[edit] The dollar bill experiment

It might be nice to change it to a ruler, so afterwards you can determine your reaction time for this experiment. Plus the fact that a whole lot of people don't readily have acces to dollar bills :)
