What occur during muscle relaxations?
Muscle tension declines, myosin releases thin filaments, and calcium levels in the sarcoplasm fall.
What events occurred during muscle relaxation?
Muscle tension declines, myosin releases thin filaments, and calcium levels in the sarcoplasm fall.
Are there more thick filaments than thin filaments in smooth muscle?
There more thin filaments than thick filaments in smooth muscle. The ratio is of the thin to thick filaments in the smooth muscle is approximately 15:1.
What protein filament is usually always ready for muscle contraction?
The structure of muscle filaments - View diagram of the structure of muscle ... These two types of filament have different structures that enable then to work together. ... Thick filaments are formed from a protein called myosin which has important ...muscle filaments cause muscles to contract,

What levels of organization is gound-up muscle?
Levels of organization of muscle ( in decreasing order)1. Muscle: Group of muscle fascicles, which work together to cause one specific movement.2. Fascicle: Bundle of muscle fibers3. Muscle fiber: Muscle cell: cylindrical cell of skeletal muscle. It has many nuclei, therefore it is called multinucleate.4. Myfibril: Contractile fibers found within a muscle cell. It has 100 - 1000's of muscle cells in each muscle fiber.5. Sarcomere: Structural and Functional unit of the muscle. It is the smallest unit of a muscle that is able to contract.6. Actin and myosin filaments: Filamentous proteins which can interact together to cause contraction.
What are the muscle structures from largest to smallest?
The organization of a skeletal muscle from smallest to largest is as follows: myofilaments > myofibrils > muscle fiber > fascicle > muscle
Do smooth muscle have thick and thin filament?
Both do have actin and myosin.Within each skeletal muscle fiber are hundreds of lengthwise subdivisions called myofibrils.Myofibrils are made up of bundles of the protein filaments (myofilaments) that are responsible for muscle contraction: thin filaments: made of the protein actin, andthick filaments: made of the protein myosin.These are visible using a microscope.The internal organization of actin and myosin in smooth muscle is different from that in the striated muscles.Smooth muscle cells: are long and slender, are spindle shaped, with a single, central nucleus, have scattered myosin fibers, with more heads per thick filament and have actin filaments attached to dense bodies.These can not be seen using a microscope and that is why they are also called smooth muscle fibers.
What muscle cell filaments come closer together when the sarcomere shortens?
thin filaments
The filaments are arranged along the muscle fiber in units called?
Actin filaments
What muscle shapes the muscle?
thick and thin bands (lines) of filaments.
