The four types of muscles identified by different patterns of organization are:
Parallel, convergent, pennate, circular
In a convergent muscle the muscle fibers are:
based over a broad area, but all the fibers come together at a common attachment site
What kind of lever is one in which the fulcrum lies between the applied force and the resistance?
A first-class lever
The effect of an arrangement where a force is applied between the resistance and the fulcrum illustrates the principles operating:
A muscle whose contraction is chiefly responsible for producing a particular movement is called
a prime mover
the type of lever in which a small force can move a larger weight is classified as a
second class lever
the increase in muscular tension produced by increasing the number of active motor units called
when the calcium ion concentration in the cytoplasm prolongs the contraction state, making it continuous, the contraction is called
a muscle producing peak tension during rapid cycles of contraction and relaxation is said to be in
an indication of how fine the control of movement can be is determined by the size of the
by controlling the number of activated muscle fibers, you can control the amount of tension produced by the
when muscles are actively contracting, the process requires large amounts of energy in the form of
at peak activity levels, most of the ATP is provided by glycolysis, leading to the production of
a skeletal muscle continues to contract even when mitochondrial activity is limited by the availability of oxygen due to the process of
the amount of oxygen used in the recovery period to restore normal pre-exertion conditions is referred to as
the amount of time of contractions in cardiac muscle tissues is determined by specialized muscle fibers called
in the digestive and urinary systems, the rings of smooth muscle that regulate the movement of materials along internal passageways are called
during development, groups of embryonic cells that fuse together to create individual muscle fibers are called
the ability of a stretched smooth muscle to function over a wide range of lengths is called
the time when a muscle cell cannot be stimulated because depolarization is occurring is the
absolute refactory period
the condition that results when a muscle is stimulated but cannot contract is referred to as
at sufficiently high stimulation frequencies, the overlapping twitches result in one strong, steady contraction referred to as
