Which one of the following statements about synaptic function is incorrect? 1. If an excitatory synapse generated a 2 mV EPSP in a neuron's dendrite and an inhibitory synapse generated a 2 mV IPSP in a neuron's cell body, the inhibitory synapse would have a stronger influence on action potential generation in the postsynaptic cell. 2. If one applied a toxin to the presynaptic membrane that blocked the opening of voltage-gated K^+ channels, transmitter release would decrease. 3. At an excitatory synapse, binding of the neurotransmitter to its postsynaptic receptor generates net inward current across the postsynaptic membrane. 4. If one applied a toxin to the presynaptic membrane that blocked the opening of voltage-gated Ca^2+ channels, the amplitude of the postsynaptic potential would increase.

The Skeletal System The is the bony framework of the human body and is the system in which every other system is built upon. • The skeletal system has main components: the vertebral column, shoulder blades, pelvic girdle, and the of the hands, arms, feet, and legs. Function: A for the body, gives the body shape, allows movement, makes blood cells, provides protection for organs and stores the minerals. Tho Shontal System

What supports a body and enables it to move? You probably have already learned that you need muscles in order to move. At the beginning of the lesson, you saw a girl support the weight of her body with just her arms by using her muscles. How do muscles work? A muscle is made of strong tissue that can contract in an orderly way. When a muscle contracts, the cells of the muscle become shorter. When the muscle relaxes, the cells return to their original length. Contracted Relaxed You might recall that mitochondria are the main energy producers in a cell. Because so much energy is required for muscle function, muscle cells are packed with mitochondria. Muscles allow for movement of the body, but they do not work alone. Brainstorm and write or illustrate what other systems help the body move. Muscles enable the body to move, but cannot function without the support of bones. Bones can move because they are attached to muscles. The skeletal system and the muscular system work together and move your body. Want more information?

What is the role of tropomyosis in vertebrate skeletal muscles? Tropomyosin serves as a contraction inhibitor by blocking the calcium binding sites on the myosin molecules Tropomyosin is the receptor for the motor neuron neurotransmiter Tropomyosin is the chemical that activate the myosin heads Tropomyosin serves as a contraction inhibitor by blocking the myosin binding sites on the actin molecules
