Skeletal muscle contraction is voluntary and under the regulation of the somatic nervous system. Each skeletal muscle cell is innervated by a motoneuron, and each muscle fiber behaves as a single unit. Smooth muscle, on the other hand, is involuntary and under the regulation of the autonomic nervous system.

To relax skeletal muscles, it is necessary to abolish voluntary muscle contractions and modify the slight tension, which is the normal state (the ‘tone’ or ‘tonus’ of the muscle). Tone is maintained by many complex mechanisms but, briefly, it can be said that all result in the slow asynchronous discharge of impulses from cells in the ventral horn region of the spinal cord. You can thus understand how that enormity of muscle can develop considerable tension in you and that numerous volleys of nerve impulses can be generated in the tiny receptors embedded in the muscle. These neural impulses generated by muscle tension are then transmitted to the brain along sensory control fibers.
The Correct Answer is. breathing. Reason Explained. breathing is correct for Botulism toxin interferes with the transmission of nerve impulses (action potentials) to skeletal muscles. Cellular Physiology of Skeletal, Cardiac, and Smooth Muscle / 9 231 ses to modulate, rather than to initiate, cardiac muscle function. In contrast to skeletal muscle, cardiac muscle contraction is triggered by electrical signals from neigh-boring cardiac muscle cells. These electrical impulses orig- Contracting muscles pressing on veins force blood towards heart causing greater filling of the ventricles which makes the heart beat faster and stronger; If blood pressure rises too far above normal, pressure receptors in the aorta and carotid (artery) sinus send nerve impulses to the CIC; CIC send inhibitory nerve impulses to the CAC and the SAN A skeletal muscle is composed of skeletal myofibers and connective tissue.
In summary, synaptic transmissions carry excitatory impulses from motor neurons to skeletal muscle cells. Calcium triggers the release of acetylcholine from the neuron. Acetylcholine then crosses
The signal, an impulse called an action potential, travels through a type of nerve cell called a motor neuron. The neuromuscular junction is the name of the place where the motor neuron reaches a muscle cell.

Muscles will contract or relax when they receive signals from the nervous system. The neuromuscular junction is the site of the signal exchange. Muscle contraction begins when the nervous system generates a signal. The signal, an impulse called an action potential, travels through a type of nerve cell called a motor neuron. The neuromuscular junction is the name of the place where the motor neuron reaches a muscle cell. Skeletal muscle tissue is composed of cells called muscle fibers.
