Concept explainers
To sketch: A longitudinal section of a sarcomere in a relaxed state and label the Z lines, thin filaments, and thick filaments.
Introduction: Sarcomere is the smallest unit of a muscle fiber. The filaments of actin and myosin are constitutively known as a sarcomere. Multiple numbers of sarcomere are joined together to form the structure of a muscle. They join together with each other in the end-to-end direction, resulting in the formation of “myofibril”.
To determine: The actin filaments in the given figure.
Introduction: Muscles consists of various units which constitutively results in the locomotion
of the organism. The functioning of muscles is carried out by the process of muscle contraction, which is a vast process and guided by a number of steps.
To determine: The myosin filaments in the given figure.
Introduction: Muscles consists of various units which constitutively results in the locomotion of the organism. The functioning of muscles is carried out by the process of muscle contraction, which is a vast process and guided by a number of steps. The skeletal system and muscle tissues act together to produce locomotion in an individual.

She recently returned from a trip to sub-Saharan Africa, where she did not take malaria prophylaxis. On examination, she is febrile (39.8°C/103.6°F) and hypotensive. Laboratory studies reveal hemoglobin of 8.0 g/dL, platelet count of 50,000/μL, and evidence of hemoglobinuria. A peripheral blood smear shows ring forms and banana-shaped gametocytes.
