Thick filaments occur only in the A band of a myofibril. The power stroke occurs when ADP and phosphate dissociate from the actin active site. The refractory period allows the voltage-sensitive ion channels to return to their resting configurations. Actin attachments to the Z line. Chapter 5 lab investigation muscles answer key 1. TendonWhat is a sarcolemma? 1 Lymphatic Ducts and Vessels. Aerobic respiration, so they do not fatigue are fast-twitched fibers specially adapted for? The sarcolemma is the site of action potential conduction, which triggers muscle contraction. 1 Anatomy of the Lungs.

SpeechMuscles provide what? Chapter 5 lab investigation muscles answer key gizmo. In relaxed muscle, the myosin-binding site on actin is blocked by ________. Because the inside of a cell is negative compared with the outside, a minus sign signifies the excess of negative charges inside the cell, −70 mV. Acts to block myosin binding sites on actin molecules, preventing cross-bridge formation and preventing contraction until a muscle receives a neuron signal. The deadly nerve gas Sarin irreversibly inhibits acetycholinesterase.

Protein do each myofibril consists of? The area of the sarcolemma on the muscle fiber that interacts with the neuron is called the motor end plate. 2, and does not require more oxygenWhat is creatine phosphate? Myofibrils ( but there is no connective tissue surrounding each of them)Each myofibril is composed of what? One sarcomere is the space between two consecutive Z discs and contains one entire A band and two halves of an I band, one on either side of the A band. 1 Labeling the Lymphatic System. That will change the voltage. The number of cross-bridges formed between actin and myosin determine the amount of tension that a muscle fiber can produce. RecruitmentMore and more motor units can achieve what? Which of the following statements about muscle contraction is true? Movement of the jaw back to the midlineWhat is flexion? It is a contraction of a muscle cell in response to a single nerve many phases does a twitch have?
Chapter 5 Lab Investigation Muscles Answer Key Chapter 1
Is a pivot point on the lever that does not move; in muscles lever systems, the fulcrum is a are classified as what? To enable a muscle contraction, tropomyosin must change conformation, uncovering the myosin-binding site on an actin molecule and allowing cross-bridge formation. However, Na+ channels are rarely open, so Na+ remains outside the cell. 2 Vertebrae Identification. In the presence of Sarin, acetycholine is not removed from the synapse, resulting in continuous stimulation of the muscle plasma membrane. The power stroke occurs when ATP is hydrolyzed to ADP and phosphate. The primary component of thin filaments is the actin protein. However, the transmembrane potential is considerably smaller (0. First, second, or third on the basis of the location of the fulcrum, effort and levers in the body are what? 4 Diagramming an Allergic Response. Electrical signals travel along the neuron's axon, which branches through the muscle and connects to individual muscle fibers at a neuromuscular junction. The ability of a muscle to generate tension immediately after stimulation is dependent on: - myosin interaction with the M line. A weight to be liftedWhat is Effort? By the end of this section, you will be able to: - Classify the different types of muscle tissue.

Proper muscle functionA gradual recruitment of additional motor units makes what? The cell membrane of a muscle fiber is called a ________. Smooth muscle has no striations, is not under voluntary control, has only one nucleus per cell, is tapered at both ends, and is called involuntary muscle. 2 The Stages of Mitosis. A small space called the synaptic cleft separates the synaptic terminal from the motor end plate. Sliding Filament Model of Contraction. 4 Cardiovascular System Statistics. For a muscle cell to contract, the sarcomere must shorten. A sarcomere is defined as the distance between two consecutive Z discs or Z lines; when a muscle contracts, the distance between the Z discs is reduced. These cells are incredibly large, with diameters of up to 100 µm and lengths of up to 30 cm.
Chapter 5 Lab Investigation Muscles Answer Key Lime
If the sarcomere is shortened even more, thin filaments begin to overlap with each other—reducing cross-bridge formation even further, and producing even less tension. A plasma membrane (cell membrane)The sarcoplasmic reticulum is the name given to what? Position of standing on the tiptoes with heels off the floorWhat is inversion? The period immediately following the transmission of an impulse in a nerve or muscle, in which a neuron or muscle cell regains its ability to transmit another impulse, is called the refractory period. The H zone—the central region of the A zone—contains only thick filaments and is shortened during contraction. How would muscle contractions be affected if ATP was completely depleted in a muscle fiber? Fatigue can result from what? 1 Anatomical Structure of a Long Bone.
2 µm in diameter, hundreds to thousands can be found inside one muscle fiber. Larger motionWhat is an isotonic movement? Myosin has another binding site for ATP at which enzymatic activity hydrolyzes ATP to ADP, releasing an inorganic phosphate molecule and energy. AcetylcholineAcetylcholine fits into receptors on the muscle cell to do what?
Each skeletal muscle fiber is a skeletal muscle cell. 3 Researching Respiratory Disorders. The enzyme at the binding site on myosin is called ATPase. From the Z line to Z are filaments attached to? This action requires energy, which is provided by ATP.
