stratum spinosum

Which ligament connects the clavicle and the acromion?


__________ best describes the term Z line.

thin filaments are anchored here.

_______ is a recognized function of skeletal muscle.

produce movement, guard body entrances and exits, maintain body temp,
maintain posture.

The most important factor in decreasing the intracellular
concentration of calcium ion after contraction is _______.

active transport of calcium into the SR.

The skeletal muscle complex known as the triad consists of _______.

a transverse tubule and two terminal cisternae.

Cross-bridges are portions of _______.

myosin molecules.

In rigor mortis _______.

myosin heads are attached to actin, cross-bridge cycling is absent,
ATP is depleted, muscles are inextensible.

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.


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


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


______ is NOT an extrinsic eye muscle.

rectus abdominos

The sternocliedomastiod inserts on the _______.

mastoid process.

________ does NOT originate on the humerus?

biceps brachii.

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.


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


______ is the role of tropomyosin in skeletal muscle.

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

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

sarcoplasmic reticulum.

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.

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.


The contractile units of skeletal muscle are ______.

a sarcomere.

Muscle tissue has all of the following properties except _______.


Hypothetically, if a muscle tissue were stretched to the point where
thick and thin filaments no longer overlapped, __________.

no muscle tension could be generated.

What part of the sarcolemma contains acetylcholine receptors?

motor end plate.

What muscle is primarily responsible for preventing foot drop?

extensor digitorum longus

Which of the following is NOT a muscle primarily involved in the
breathing process?

latissimus dorsi

What is the muscle that provides the major force for producing a
specific movement called?

an agonist (prime mover).

________ muscle inserts to the posterior calcaneus via the calcaneal tendon?

the gastrosnemius

What type of muscle assists an agonist by causing a like movement or
by stabilizing a joint over which an agonist acts?

a synergist.

In general, a muscle that crosses on the anterior side of a joint
produces ________.


________ is a powerful forearm extensor.

triceps brachii

Nerve impulses are sent to slow the hearts rate of contraction. The
nerve fibers sending these signals will most likely belong to which
division of the nervous system?

parasympathetic division

When nuerotransmitter like acetylcholine is acting in an excitatory
manner which of the following is likely a result of the acetylcholine
acting on the post synaptic cell?

chemically gated sodium channels will open.
