  • 18:0518:05, 30 March 2024 diff hist +1,322 N The Song of the Cell Created page with "Every cell in a multicellular organism is surrounded by an oily membrane that separates it from other cells and from the extracellular fluid that bathes all cells. The cell surface membrane is permeable to certain substances, thereby allowing an exchange of nutrients and gases to take place between the interior of the cell and the fluid surrounding it. Inside the cell is the nucleus, which has a membrane of its own and is surrounded by an intracellular fluid called the c..."

Receives sensory information from the skin through bundles of long nerve fibers, called axons, and transforms it into coordinated motor commands that are relayed to the muscles for action through other bundles of nerves ** Spinal cord - contains the machinery needed for simple reflex behaviors. ** Brain stem - conveys sensory information to higher..."
