Answer:
The process is called - Motor unit recruitment.
Explanation:
Motor unit recruitment
Motor unit recruitment helps to increase the contractile strength of the muscle by activation of the additional motor units.
A motor unit consists of motor neuron and all the skeletal muscle fibers that are innervated by axon terminal of the motor neuron. The collection of motor units work together to coordinate contractions of single muscle
Now, when a motor neuron gets activated , all the muscle fibers gets innervated by the motor neuron and stimulated and contracts , this activation of the motor neuron will cause the weak muscle contraction.
As a result , activation of more number of motor neurons will cause more activation of muscle fibers and hence, lead to stronger muscle contraction.
Some of your peripheral nervous system (PNS) is under your voluntary control - the nerves that carry instructions from your brain to your limbs, for example. As well as controlling your muscles and joints, it sends all the information from your senses back to your brain. Other parts of your PNS are controlled by the brain automatically. This is the autonomic nervous system. It manages some things your body does 'without thinking' like digestion and temperature control. Just word it a bit differently so it’s not direct plagiarism
Answer:The final step in both pathways would be the activation of factor X, leading to conversion of prothrombin II to thrombin IIa. Option C.
Explanation: blood coagulation is the processes that leads to blood clot formation. The blood clot formed is made up of fibrin and platelets, which forms hemostatic plug over a wound site. The blood coagulation is made up of two partways that led to the formation of clot. The intrinsic pathway also called contact activation pathway and the extrinsic pathway which is also known as the tissue factor pathway. The both pathways are connected by a common pathway whereby factor X is activated leading to leading to conversion of prothrombin II to thrombin IIa. Thrombin then converts fibrinogen to fibrin( blood clot). I hope this helps. Thanks.
