ap lab exam 3

List two of the seven criteria listed in your lab manual that are used to name muscles?

What are the individual contractile units of a muscle cell called?

If a muscle contracts against a load that is too heavy for the muscle to lift, what type of contraction is the muscle demonstrating?

By steadily increasing the number of motor units that are activated, we produce a steady increase in the force produced by a muscle. This process is called __________________?

A single contraction of a muscle is called a _____________?

If we stimulate a muscle, and then stimulate it again immediately after it has been allowed to relax, we observe that the second contraction of the muscle is slightly greater than the first. What do we call this phenomenon?

What do we call muscles that are primarily responsible for producing a specific movement?

Define "origin" as it applies to skeletal muscles.

Name one action of the zygomaticus minor muscle.

Name one action of the semimembanosus muscle.

Name one action of the pectoralis major muscle.

Name one action of the deltoid muscle.

Name one origin of the semitendinosus muscle.

Name one origin of the buccinator muscle.

Name one origin of the sternocleidomastoid muscle.

Name one origin of the tibialis anterior muscle.

What neurotransmitter do motor neurons use to stimulate muscle cells?

If we increase the frequence of stimulation of a muscle untill we acheive a steady sustained contraction, we will have caused what phenomenon?

A neuron and all of the muscle cells that it stimulates are together called a _________________?

What do we call muscles that aid the action of other muscles by reducing undesirable or unnecessary movement?

Define "insertion" as it applies to skeletal muscles.

Name one action of the sternocleidomastoid muscle.
