Muscle Structure
Connective tissue that keeps fasciculi together and eventually transitions into a tendon.
Epimysium
A muscle contraction where the muscle does not change length.
Isometric contraction
Muscle tissue only found in the heart.
Cardiac muscle
This muscle is considered as the prime mover in a muscle pair.
Agonist muscle
The ____________ receives the initial stimulus.
Receptor
Surrounds the cell membrane of a muscle cell/fibre.
Endomysium
An isometric contraction has two sub categories of contraction which are...
concentric, eccentric.
Muscle tissue that surrounds the small intestines.
Smooth muscle
Opposes the movement of the prime mover.
The ___________ interprets a signal and initiates an appropriate response.
Interneuron(s)
Contractile units that contain myosin and actin.
Sarcomeres
The A band in a muscle fibre changes length during a concentric contraction (True/False).
False
Muscle tissue that is striated and voluntary.
Skeletal muscle
In a muscle pair, this muscle may assist the prime mover in its action and help stabilize the joint.
Synergist muscle
A proprioceptor that helps maintain muscle tension and is sensitive to changes in muscle length.
Muscle spindles
Has receptors on its surface for neurotransmitters that are sent from the motor neuron.
Sarcolemma
Calcium ions bind to _____________ in order to move tropomyosin out of the way of myosin binding sites.
Troponin
The attachment point of the muscle that is further away from the midline of the body, or that moves the most, is called...
Insertion
An overuse injury where the tendon becomes more irritated.
Tendonitis
Detects changes in muscle tension.
Golgi tendon organ
Calcium from the sarcoplasmic reticulum gets released into this space.
Sarcoplasm
______________ is responsible for detaching myosin heads from actin in order to provide it with energy to bind again. It is also responsible for helping to pump calcium ions back into the sarcoplasmic reticulum
Adenosine Triphosphate (ATP)
The latisimus dori muscles (lats), are indirectly attached to bone by a sheet of connective tissue called ______________.
Aponeurosis
__________________ can be prevented with a proper warm-up and cool-down or gradually increasing the intensity of exercise. To recover, it may be helpful to apply ice, stretch, and rest.
Delayed Onset Muscle Soreness (DOMS)
