An agonist for elbow flexion is _____, whereas the ______ is an antagonist to this movement.
biceps brachii, triceps brachii
Brachioradialis and sternocleidomastoid are named for:
the location of their origin and insertion.
commonly referred to as ____, this muscle group on the posterior thigh extends the hip.
extends and abducts the wrist
extensor carpi radialis longus and brevis
extends the thumb
extensor pollicus longus and brevis
flexes the wrist
flexor carpi ulnaris
Like the deltoid muscle that lies over and abducts the shoulder, these two muscles lie over the hip and are prime movers of hip abduction. neither muscle extends the hip.
Gluteus medius and gluteus minimus
Located over the mandibular ramus, this muscle closes the jaw
A muscle located on the anterior surface of the thigh will _____ the knee, whereas a muscle on the posterior surface will ______ the knee.
Muscles are named based on all the criteria below except
color of the muscle.
muscles that aids another by promoting the same movement
muscles that is primarily responsible for bringing about a particular movement
muscle that OPPOSES and reverses the action of another muscle
muscle that STABILIZES the origin of another muscle
The names of these muscles tell you their actions.
brachioradialis and sternocleidomastoid
Pectoralis major orginates on the _____________ and inserts in the intertubercular sulcus of the humerus.
clavicle and sternum
powerful wrist flexor that also stabilizes the wrist during finger extension
flexor carpi ulnaris
A prime mover (agonist)
is primarily responsible for movement.
Flexion of Biceps Bracci is what type of contraction?
Extension of Biceps Bracci is what type of contraction?
What is the type of chemical reaction used to rebuild ADP into ATP?
Hint: A water molecule must be removed in this process where molecules are combined.
Which of the following processes produces molecules of ATP and has two pyruvic acid molecules as end products?
Which of the following processes produces 36 ATP?
Krebs cycle and oxidative phosphorylation
The "rest and recovery" period, where the muscle restores depleted reserves, includes all of the following processes EXCEPT __________.
Hint 1. These processes are usually referred to as repaying the oxygen debt.
c. Pyruvic acid is converted back to lactic acid.
Which type of muscle fiber has a large quantity of glycogen and mainly uses glycolysis to synthesize ATP?
Hint: These fibers also have reduced myoglobin and very few capillaries surrounding them.
white fast twitch fibers
