module 4 muscular system

what is an sarcolemma

• The sarcolemma is a type of muscle fiber.
• The sarcolemma is the cell membrane of a muscle cell.
• The sarcolemma is a protein that helps muscles contract.
• The sarcolemma is a type of connective tissue in muscles.

what is an sarcolemma reticulum

• A type of connective tissue
• A component of the nervous system
• network of closed sac-like membranes

• A type of muscle fiber

what is an Nuclei

• The nucleus is the central part of an atom.
• The nucleus is a type of cell organelle.
• Nuclei are responsible for energy production in cells.
• Nuclei are found only in plant cells.

what is an mitochondria

• Mitochondria are organelles that produce energy for the cell.
• Mitochondria are a type of bacteria that invade cells.
• Mitochondria are responsible for protein synthesis.
• Mitochondria are the cell's nucleus.

what are T-Tubules

• T-tubules are responsible for oxygen transport in blood.
• T-tubules are found only in cardiac muscle cells.
• are extensions of the cell membrane that penetrate into the center of skeletal and cardiac muscle cells.

• T-tubules are a type of muscle fiber.

what are myofibrils

• Myofibrils are found in plant cells.
• Myofibrils are the contractile threads found in striated muscle cells.
• Myofibrils are a type of nerve cell.
• Myofibrils are responsible for oxygen transport in the blood.

Myofibrils contains specialized proteins referred to as?

Sacromeres

• Sarcomeres are the basic contractile units of muscle.
• Sarcomeres are responsible for oxygen transport in blood.
• Sarcomeres are found only in cardiac muscle.
• Sarcomeres are the units of nerve transmission.

what unique arrangement allow for muscle contraction to occur

what are the two type of myofilaments?

• Thick filaments and thin filaments
• Short filaments and long filaments
• Elastic filaments and rigid filaments
