The connective tissue that surrounds individual skeletal muscle fibers (myofibers) is called A. superficial fascia B. epimysium C. perimysium D. endomysium E. myomysium 3. What type of muscle tissue consists of cells with only one nucleus and junctions between cells? A. skeletal muscle B. smooth muscle C. cardiac muscle D. all of the above 4. The sodium potassium pump A. is present in neuronal and muscle tissues B. is responsible for maintaining the ion gradient across the cell membrane C. is responsible for maintaining the resting membrane potential D. requires ATP energy E. all of the above 5. The label for EL in the diagram below represents the A. H-zone. B. Z-line. C. M-line. D. T-tubule. 6. Saltatory propagation differs from continuous propagation, because salutatory propagation A. is slower B. using all segments along the axon C. is typical in small diameter neurons D. is unmyelinated E. None of the aboveExplanation / Answer
1. E) Insulin secretion: Insulin secreted by pancreas
Fuctions of muscles:
Stability: The skeletal muscle provide stability to body by supporting spine
Heat production: High metabolic rate of contracting muscle produce heat as byproduct. This helps body to maintain its temperature.
Control of openings: Sphincter muscle control opening. Example External anal sphincter
Movement: Skeletal muscle responsible for movement of organ
