10

The most common level system in the body are those that have the applied force between the fulcrum and the load. These are called ______ levers.

third-class.

11

A muscle that assists the muscle that is primarily responsible for a given action is a(n) ________.

synergist.

12

Muscles including the term capitis would be found within or attached to the ______.

head.

13

______ is NOT an extrinsic eye muscle.

rectus abdominos

14

The sternocliedomastiod inserts on the _______.

mastoid process.

15

________ does NOT originate on the humerus?

In assessing a stroke patient, you ask her to stick out her tongue. You note that it deviates to one side. You suspect that damage to the neural control of the ______ muscle has occured.

genioglossus.

17

The ______ nervous system is composed of the brain and spinal cord.

Central.

18

______ is the role of tropomyosin in skeletal muscle.

Tropomyosin serves as a contraction inhibitor by blocking the myosin binding sites on the actin molecules.

19

_______ = structure in skeletal muscle that functions in calcium storage.

sarcoplasmic reticulum.

20

What does excess post exercise oxygen consumption represent?

the difference between the amount of oxygen needed for totally aerobic muscle activity and the amount actually used.

21

Immediately following the arrival of the stimulus at a skeletal muscle cell there is a short period called the ______ period during which the neurotransmitter is released by exocytosis, diffuses across the synaptic cleft and binds to its receptors.

latent.
