Answer 1

Creatine phosphate in the muscle is used to Regenerate ATP from ADP.

In addition to glucose, muscle can also use creatine phosphate as secondary source of energy for sustained exercise.

A threshold is strong enough to give one action potential is NOT true of action potential frequency.

True statement about smooth muscle is non-straited, and cells are spindle-shaped.

Sacrolemma of a muscle fiber sends extension into the interior of the muscle fiber called T-tubules.

Functional units of individual myofibrils are called Sacromeres.

A sacromere extends from one z disk to another z disk which is True.

The oligodendrocytes form The myelin sheath around CNS axons.

ATP is needed during muscle contraction at three places. One of them is to get calcium to the actin filament.

Microglia cells respond to inflammation and are phagocytosis.

Function of smooth muscle is Respiration.

The Continued movement of potassium ions out of the cell during lateral part of action potential generates Depolarization.

The action potential usually enters to neuron B through Axon.

Tiny ares of naked axion between schwann cells or oligodendrocytes wraps are called nodes of ranvier which is True.

A threshold stimuls is the minimum stimuls that will produce action potential which is True.

The all-or-none principle for action potential states that muscle fiber will either produced a full strength action potential or none at all. And the action potentials are all of same amplitude whic is True statement.

Schwann cells form The myelin sheath around PNS axons.

An action potential generates a local current that causes depolarization at the adjacent area is true about action potential propagation.
