Type II skeletal muscle fiber twitch speed higher brain cent

Type II skeletal muscle fiber twitch speed higher brain center for muscle action, the basal _____ (old name) series _____ component muscle filament composition of the I band simple knee jerk reflex neuron pathway all-or- ________ motor neurons traveling to skeletal muscles neurotransmitter released from all motor axons \"piggyback\" of a twitch on top of another, stronger twitch contraction during which the muscle does shorten one single muscle cell nuclear ___________ fibers are loose in the muscle spindle apparatus color of slow-twitch fibers due to myoglobin pigmentation another name for a reflex pathway innervation to the antagonist muscles while agonists contract descending tracts controlling fine voluntary movements name for the muscle being moved the smallest unit of muscle contraction actin or myosin, for example sustained muscle contraction high-energy phosphate molecule required for contraction and relaxation of muscles tendon organs inhibiting the agonist muscle contractions the ion required for muscle excitation-contraction coupling includes the brain and spinal cord name of motoneurons to muscle spindles the appearance of actin molecules contractions during which the muscle does not shorten excitation of both alpha and gamma motoneurons simultaneously muscle whose contractions open the angle of joints one complete contraction-relaxation cycle of a muscle collective name for descending higher motor neurons involving many brain nuclei is ______ pyramidal the sensory apparatus within the muscle responding to the stretch of a muscle efferent motoneurons innervating the extrafusal muscle fibers actin and myosin form cross- ________ inability to maintain muscle tension any longer - perhaps due to a lack of ATP thick sarcomere filament Ca^2+ is stored in the terminal cisternae of the ___ plasmic reticulum

Solution

As the puzzle has not been given I am giving aswers in a general manner.

Across:

9. I band composed of thin filament which is also known as Actin protein. Nebulin also make a part of I band.

12. Patellar reflex which is also known as reflex arc is a stretch reflex.

18. All vertebrate motor neuron are known to secrete Acetylcholine that is why these neurons are known as Cholinergic.

22. This is known as concentric contraction. In this the muscle maximum always remains lesser than the force generated by the muscle itself.
