CMQ9 Question 1 Match the word roots to the definition or meaning. Something written Of one’s free will Together Flesh Bundle Muscle Equal Work A net Hidden Over, more Stretched Well fed Stiff Between Something inserted Marks for this submission: 16/16. Question 2 Layers of dense connective tissue that separate an individual muscle from adjacent muscles, hold it in position, and extend into the muscle to form partitions between muscle bundles and are continuous with attachments of muscle to the periosteum are called are called Choose one answer. a. Ligaments b. Fascia c. Tendons d. Elastin Marks for this submission: 1/1. Question 3 Match the these terms about muscle anatomy and processes to its description or function. The response of muscle tissue to stimulation is to Bundles of muscle fibers are called Smooth body movements depend on antagonists giving way to The partial contraction of skeletal muscles after death is called The thin deep fascial connective tissue that covers individual muscle fibers within a fascicle is the The functional unit or segment of the myofibril between two successive Z lines is called a Each bundle of muscle fibers is covered by layers of connective tissue called fascia or The primary source of energy to reconstruct ATP from ADP and phosphate is the process of cellular respiration or The attachment of a muscle to a relatively movable part is called the The minimal strength stimulus needed to elicit contraction of a single muscle fiber is called a Marks for this submission: 10/10. Question 4 Striated muscle tissue is also known as ________. a. Voluntary b. Skeletal c. Involuntary d. Visceral Marks for this submission: 0/1. Question 5 Membrane Charge Differences Normal activity of the sodium-potassium pumps in the NOT Schwann Cells and not Axon functions to pump sodium and calcium and potassium the neuron, creating a charged condition called the . A stimulus to a neuron causes changes in the cell membrane which spread over the surface of the neuron. In the membrane are many electrically-stimulated channel proteins which form which open briefly when stimulated. The momentary- opening allows movement of sodium ions and potassium ions the cells down their electrochemical gradients.

The momentary opening of the channels thus causes a depolarization of the membrane, which further stimulates neighboring membrane channels to open. The effect eventually spreads over the entire surface of the neuron. This ripple-effect is called the . After the channels close, the sodium-potassium pump works to restore the normal higher concentration of potassium within the cell and sodium outside. Partially correct Marks for this submission: 7/8. Question 6 Muscle Fiber Structure The action potential spreads over the [10] of the muscle fiber. Within the membrane are deep invaginations [6, 4] called . These structures serve as extensions of the cell membrane down into the [9] and wrap around the [2] . These are the contractile structures of the muscle fiber, consisting of thin filaments of
