<u>Explanation:</u>
A volunteer muscle works generally across a joint. It is attached by strong cords called as tendons to both bones. Usually just one bone moves when muscles contract. Flexion and extension are usually body forward and backward movements, such as head nodding. Flexion: decreasing angle (bending) between two bones. Extension: to increase the angle between two bones (to straighten a curve).
"Reverse motions" require antagonistic pairs located on opposite sides of a joint or bone that include pairs of flexor-extensors. Both consist of an extensor muscle, which will "open" the joint (increasing the angle between the two bones) and a flexor muscle, which will do the reverse by reducing the angle between two.
Answer:
Extinction
Explanation:
For example, your dog will naturally salivate at he sight of food, but if you train your dog to salivate when you ring a bell when presenting food to it, the dog overtime associates the bell with food, and would salivate anytime you ring a bell even without presenting its food.
The salivation that is stimulated by the ringing of the bell even in the absence of food is the conditioned response.
The ringing of the bell is the conditioned stimulus, while the food that naturally initiates salivation is the unconditioned stimulus.
Overtime, if you keep ringing the bell (conditioned stimulus) only without presenting food (unconditioned stimulus), your dog would gradually stop salivating without sighting food. This reduction or decrease in the conditioned response (salivating) is what is referred to as extinction.
Takeoff. Generally, a right-handed long jumper takes off with the left foot. New jumpers may wish to try both to which style works best. When you hit the takeoff board, your body will actually be leaning slightly backward, with your foot in front, your hips slightly behind and your shoulders a bit behind your hips.
