[Anarchy]

یه چیزی الان راجع به این معجزه قرآن که در مورد پوست هست یادم افتاد! اینکه اعصاب فهم گرما و سوختگی فقط روی پوست باشد غلط است چرا که همه ما در سریالها و فیلمها دیده ایم که کسانی که زخم عمیق برمیدارن مثلا یک فلز داغ مثل چاقو را روی زخمشون میذارن و خیلی هم داد و هوار میکنن! پس اعصاب احساس گرما و سوختگی فقط روی پوست نیست.

گیرنده های حسی تقریبا تو کل بدن وجود دارن و به پوست محدود نیستن :

Nociceptor - WiKi

A nociceptor is a receptor of a sensory neuron (nerve cell) that responds to potentially damaging stimuli by sending signals to the spinal cord and brain. This process, called nociception, usually causes the perception of pain.

In mammals, nociceptors are sensory neurons that are found in any area of the body that can sense noxious stimuli either externally or internally. External examples are in tissues such as skin (cutaneous nociceptors), cornea and mucosa. Internal nociceptors are in a variety of organs, such as the muscle, joint, bladder, gut and continuing along the digestive tract. The cell bodies of these neurons are located in either the dorsal root ganglia or the trigeminal ganglia.[SUP][2][/SUP] The trigeminal ganglia are specialized nerves for the face, whereas the dorsal root ganglia associate with the rest of the body. The axons extend into the peripheral nervous system and terminate in branches to form receptive fields.
