[1] [2] [3] The calcium ion concentration in sarcoplasm is also a special element of the muscle fiber; it is the means by which muscle contractions take place and are regulated. [ 4 ] [ 5 ] The sarcoplasm plays a critical role in muscle contraction as an increase in Ca 2+ concentration in the sarcoplasm begins the process of filament sliding.
Three distinct types of muscle (L to R): Smooth (non-striated) muscle in internal organs, cardiac or heart muscle, and skeletal muscle. There are three distinct types of muscle: skeletal muscle, cardiac or heart muscle, and smooth (non-striated) muscle. Muscles provide strength, balance, posture, movement, and heat for the body to keep warm. [3]
In 1967, the Institute was upgraded to polytechnic and renamed Government Institute of Textile Chemistry and Knitting Technology, Ludhiana. The present Institute is an amalgamation of two old Institutes viz. Government Hosiery Institute, Ludhiana (established 1926) and Government Institute of Dyeing and Calico Printing Ludhiana (established 1923) located in the same premises.
Muscle tissue contains special contractile proteins called actin and myosin which interact to cause movement. Among many other muscle proteins, present are two regulatory proteins, troponin and tropomyosin. [1] Muscle tissue varies with function and location in the body. In vertebrates, the three types are: skeletal, cardiac (both striated), and
The main function of striated muscle tissue is to create force and contract. These contractions in cardiac muscle will pump blood throughout the body. In skeletal muscle the contractions enable breathing, movement, and posture maintenance. [1] Contractions in cardiac muscle tissue are due to a myogenic response of the heart's pacemaker cells ...
Alpha-actin is also expressed as distinct genetic isoforms such as smooth muscle, cardiac muscle and skeletal muscle specific isoforms of alpha-actin. [10] The ratio of actin to myosin is between 2:1 [8] and 10:1 [8] in smooth muscle. Conversely, from a mass ratio standpoint (as opposed to a molar ratio), myosin is the dominant protein in ...
The Board is headed by a full-time Chairman whose term lasts three years and who technically reports to the Secretary of School Education in the Government of Punjab.The current Education Secretary of the board is IAS Sh Harsant Singh sekhon who is sincerely committed to shape the education system of Punjab by his pioneering Initiatives like ...
A wide variety of body composition measurement methods exist. The gold standard measurement technique for the 4-compartment model consists of a weight measurement, body density measurement using hydrostatic weighing or air displacement plethysmography, total body water calculation using isotope dilution analysis, and mineral content measurement by dual-energy X-ray absorptiometry (DEXA).
