The muscle plays a crucial role in walking by contracting and relaxing to move the bones and joints, providing the necessary force and movement for walking.
When the shank is flexed as in walking, the gastrocnemius muscle is contracted. This allows for plantar flexion of the foot, pushing the body forward during the walking motion. The gastrocnemius muscle plays a critical role in the propulsion phase of walking.
Yes, T-tubules play a role in storing calcium within muscle cells by helping to facilitate the release of calcium from the sarcoplasmic reticulum during muscle contraction.
The hip muscles play a crucial role in walking by providing stability, support, and power to the movement of the legs and pelvis. They help to control the movement of the hip joint and facilitate the swinging motion of the legs during each step.
Myofibrils play a fundamental role in muscle contraction and generating force in skeletal muscle. They are composed of thick and thin filaments that slide past each other during contraction, causing muscle fibers to shorten and produce movement.
Your brain is fat.
the role of the heart is to supply the working muscle with oxygen and energy
One direction is awesome
The i band in muscle physiology is important because it contains the thin filaments made of actin. These filaments play a crucial role in muscle contraction by interacting with the thick filaments made of myosin. The i band shortens during muscle contraction, allowing the muscle to generate force and movement.
The nuclei in skeletal muscle cells are located on the periphery, near the cell membrane. These nuclei are important for controlling protein synthesis and cell repair in muscle cells. They play a crucial role in regulating muscle growth, repair, and adaptation to exercise.
The muscle responsible for dorsiflexion and eversion of the foot is the tibialis anterior. This muscle is located in the front of the lower leg and plays a key role in lifting the foot upward and turning the sole outward. Its contraction allows for better clearance of the foot during walking and helps maintain balance.
Screw this. IM Dropping OUT
the diaphragm play an important role in breathing. hope it helped....
