Section 6.1: A skeletal muscle contains skeletal muscle tissue, connective tissues, blood vessels, and nerves
Section 6.2: Skeletal muscle fibers have contractile myofibrils containing hundreds to thousands of sarcomers
Section 6.3: A skeletal muscle fiber contracts when stimulated by a motor neuron
Section 6.4: The sliding filament theory explains the physical changes that occur during a contraction
Section 6.5: A muscle fiber contraction uses ATP in a cycle that repeats for the duration of the contraction
Section EOS1: End of Section 1
Section 6.6: Tension production rises to maximum levels as the rate of muscle stimulation increases
Section 6.7: A skeletal muscle controls muscle tension by the number of motor units stimulated
Section 6.8: Muscle contractions may be isotonic or isometric
Section 6.9: Muscle contraction requires a large amount of ATP that may be produced aerobically or anerobically
Section 6.10: Clinical Module: Many factors can result in muscle hypertrophy, atrophy, or paralysis
Section EOS2: End of Section 2
Section 6.11: The names of muscles provide clues to their appearance and or function
Section 6.12: Broad descriptive terms are used to describe movements with reference to the autonomical position
Section 6.13: Terms of more limited application describe rotational movements and special movements
Section 6.14: Skeletal muscles are grouped in the axial division or appendicular division based on origins and functions
Section 6.15: The muscles of the head and neck are important in eating and useful for communication
Section 6.16: The muscles of the vertebral column support and align the axial skeleton
Section 6.17: The oblique and rectus muscles form the muscular walls of the trunk
Section 6.18: Large axial and appendicular muscles originate on the trunk
Section 6.19: Proximal limb muscles are larger, stronger, fewer, and less precise in their actions than distal limb muscles
Section 6.20: The muscles that move the leg originate on the pelvis and femur
Section 6.21: The primary muscles that move the foot and toes originate on the tibia and fibula
Section EOS3: End of Section 3

Here is a tip:

Both tendons and aponeurosis are connective tissues.                                                                                                                                   

Explanation

Tendon attaches skeletal muscle to a point on the bone, whereas aponeurosis attaches the muscle to a broad area on the bone. The collagen fibers of tendons and aponeurosis extend into the bone matrix, providing a firm attachment and facilitating bone movement when the muscle contracts.

Verified Answer

  • Tendon is a bundle formed as the connective tissue fibers at the ends of the muscle merge.
  • Aponeurosis is a broad sheet of connective tissue at the end of skeletal muscles.
