Human Senses

Postby ShalashakaOcelot » Mon May 22, 2006 11:21 pm

My idiotic teacher assigned us pages that she hasn't gone over in class, so I'm at a bit of a loss.

The first thing I need to know is "Your finger brushes against a hot stove and you quickly pull away. Identify which two human body systems work together to respond to this painful stimulus and explain the specific interaction between them."

I can't really find it in the textbook (it has about 1 page on senses), so yeah... help a idiotic 13 year old here.

Isn't one of those systems is the nervous system?

Ok, i'm going to answer your question for you, just to show how simple it woul have been if your teacher would have gone at least over the basics.
Actually, there are 3 systems working together here:
1. The tegumentary sistem: the pain receptors feel the pain and transmit the signal forward to the nervous system.
2. The nervous system: the meesage is tramitted from the receptor(pain receptor in our case) to the efector(muscle cell)
3. Locomotory system: the muscle contracts, and your hand quickly pules from the hot stove.

See, it is easy. Just think about it logically. Logics is very important in understanding biology

Well that sounds like a little "DISCOVERY LEARNING". Working through a new problem or challenge tends to increase understanding and long term retention better than just memorizing some facts. But you have to know a little bit about it when you start...that's called prerequisit knowledge. It takes longer but it last longer and that is a good thing if you do it right.

If you really want to blow your teachers mind, look up some stuff on "monosynaptic reflex arc". If that stove is really hot, you actually pull you hand away before you brain tell you it is hot...it is a REFLEX. Look up reflex too.

smarty pants Doc44, the nociceptive reflex of retracting a limb when feeling pain is not monosynaptic, it is the classic example of a polisynaptic medular reflex.

yes. and also a good concentration on it and knowledge to produce idea.
oh, and a clearly-thinking. :)
if you had have them all except logic, it will not give a good result.
:D
