What is an alternative for Borax Powder? I am making slime for a demonstration speech in my speech class. I need to find an alternative for Borax Powder. You&#39;re supposed to combine it with water and glue to make the slime but I am unable to get Borax Powder.
The nervous system derives its name from nerves, which are cylindrical bundles of fibers (the axons of neurons), that emanate from the brain and spinal cord, and branch repeatedly to innervate every part of the body.he size of the nervous system ranges from a few hundred cells in the simplest worms, to around 100 billion cells in humans. The central nervous system functions to send signals from one cell to others, or from one part of the body to others and to receive feedback.
The Stretch Reflex : (See Figure 13.15). The stretch reflex in its simplest form involves only 2 neurons, and is therefore sometimes called a 2-neuron reflex. The two neurons are a sensory and a motor neuron. The sensory neuron is stimulated by stretch (extension) of a muscle.Stretch of a muscle normally happens when its antagonist contracts, or artificially when its tendon is stretched, as in the knee jerk reflex.Muscles contain receptors called muscle spindles. (See Figure 13.13) These receptors respond to the muscles's stretch.he two neurons are a sensory and a motor neuron. The sensory neuron is stimulated by stretch (extension) of a muscle.
