Muscle contractions tend to be smooth and vary in strengths‚ depending on the demands placed on them. The variations of strength are called graded muscle responses. There are two ways a muscle contraction can be graded‚ either by changing the frequency of stimulation or by changing the strength of the stimulation. When a muscle is responding to a change in stimulus frequency‚ the nervous system will reach a greater muscular force when increasing the firing of motor neurons. This causes a wave or

the 4 periods that Piaget envisioned are summarized in the following table that I developed from Berger chapter 6 on page 49 for assignment 2. The term operational origins come from work and produce so the operational stages are related to productive thinking. In the sensorimotor stages the child is developing an understanding of their senses and their bodies and how the information coming from its sensors is processed. In preoperational children are developing higher level thinking and symbolically

During a Muscle Contraction The muscle fiber is in a resting state. The resting state is slightly negative inside and slightly positive outside. It has to be in this state in order to receive a message. First the brain sends a message to the muscle using a neuron then reaches the axon terminal of the neuron. Calcium gates then open on the axon terminal allowing calcium to rush in. Ach release from axon terminals‚ diffuses across the synaptic clef and binds to (receptors) on motor end plate. Then
Premium Acetylcholine Action potential Myosin
The series of events prompting muscle contraction is started some place in the central nervous system‚ either as willful action from the brain or as reflex action from the spinal cord. Beginning with depolarization at the neuromuscular junction‚ the depolarizing impulse discharges acetylcholine from the nerve ending. Which then diffuses over the neuromuscular junction (a chemical synapse formed by the contact between a motor neuron and a muscle fiber). At the motor end plate‚ the acetylcholine joins
