Question: Cardiac muscle cells are like skeletal muscle cells in that they bothSelect one:a. lack sarcomeres.b. have striations.c. depolarize as a result of image and image influxes.d. possess intercalated disks.e. are multinucleated.Striated cardiac and skeletal muscles play very different roles in the body, but they are similar at the molecular level. In particular, contraction, regardless of the type of muscle, is a precise and complex process involving the integral protein myofilaments and their associated regulatory components.NUR 154 Final exam > MuscularSkeletal system Week 9 > Flashcards. 1. Q. 1) Muscles exhibit the property of excitability. This means that the muscle. A) shortens its length. B) recoils to its original resting length. C) stretches beyond its normal length. D) responds to stimulation by the nervous system. Alternate route of blood to a body part through anastomosis. Collateral circulation in heart. may allow bypass of a blocked coronary artery. 33. Intercalated discs in cardiac myocytes: 1. have desmosomes- help hold muscle fibers together. 2. have gap junctions- allow AP to conduct from one muscle fiber to the next. The actin and myosin proteins are arranged very regularly in the cytoplasm of individual muscle cells (referred to as fibers) in both skeletal muscle and cardiac muscle, which creates a pattern, or stripes, called striations. The striations are visible with a light microscope under high magnification (see Figure 10.2).Muscles attach to bones directly or through tendons or aponeuroses. Skeletal muscles maintain posture, stabilize joints, support organs, control internal movement, and generate heat. Skeletal muscle fibers are long, multinucleated cells. The membrane of the cell is the sarcolemma; the cytoplasm of the cell is the sarcoplasm.Coming to the question, 1. Striated muscles are called voluntary muscles because they work on our own will . They get tired easily. 2. Striated muscles are attached to bones and help in the movement of body parts.

However, cardiac muscle fibers are shorter than skeletal muscle fibers and usually contain only one nucleus, which is located in the central region of the cell. Cardiac muscle fibers also ...Striated muscle tissue is a muscle tissue that features repeating functional units called sarcomeres. The presence of sarcomeres manifests as a series of bands visible along the muscle fibers, which is responsible for the striated appearance observed in microscopic images of this tissue.

Similar to cardiac muscle, however, skeletal muscle is striated; its long, thin, multinucleated ...Muscle tissue is composed of cells specialized for contraction. Muscle is classified into three types according to their structure and function: Skeletal and cardiac muscle cells are called striated because they show an alternating series of bands. The repeating arrangement of their basic contractile unit, the sarcomere, produces these striations.Striated muscle structure and function. Striated muscles are highly organized tissues ( Fig. 1) that convert chemical energy to physical work. The primary function of striated muscles is to generate force and contract in order to support respiration, locomotion, and posture (skeletal muscle) and to pump blood throughout the body (cardiac muscle).Troponin C (TnC) is a key regulatory protein in striated muscle contraction where its function is to bind Ca 2+, which subsequently triggers actomyosin interactions and initiates muscle contraction (Farah and Reinach, 1995). The TNNC1 gene expresses TnC in both cardiac and slow skeletal muscle (Song et al., 1996).The muscles all begin the actual process of contracting (shortening) when a protein called actin is pulled by a protein called myosin. This occurs in striated muscle (skeletal and cardiac) after specific binding sites on the actin have been exposed in response to the interaction between calcium ions (Ca ++) and proteins (troponin and tropomyosin) that "shield" the actin-binding sites.View Module 3 quiz.docx from BIO -210-Q3697 at Southern New Hampshire University.
