Motor neuron

Motoneurons are the nerve cells responsible for the formation and coordination of movements. According to the location of the motoneurons, a distinction is made between the “upper motoneurons”, which are located in the cerebral cortex, and the “lower motoneurons”, which are located in the spinal cord. The lower motor neuron The lower motoneuron is located … Motor neuron

Troponin

Definition The protein troponin is an important component of the contractile apparatus of the heart and skeletal muscles. Together with tropomyosin, its main task is the regulation of muscle contraction at the microscopic level. Troponin is a complex of the building blocks troponin T, I and C, each of which has its own partial function … Troponin

Function | Troponin

Function The entire troponin complex consists of troponin C, I and T. In the skeletal and cardiac muscle, troponin I and T together with the muscle protein tropomyosin act like an applied brake on muscle contraction. This is presumably done by simply covering and thus blocking the interaction sites of the contractile muscle proteins at … Function | Troponin
