cordlike and connects muscles to bones; a broad, fibrous sheet of connective tissue that connects muscles to muscles
A tendon is _________, whereas an aponeurosis is ___________.
The amount of oxygen liver cells require to react lactic acid to produce glucose or the glycogen glycogen is the ________.
decreased ATP and increased permeability to calcium
Rigor mortis affects skeletal muscles a few hours after death, due to _________.
4, 1, 3, 6, 2, 5
4. The impulse arrives at the synapse and travels through the transverse tubules.
1. The muscle impulse reaches the sarcoplasmic reticulum and calcium is released.
3. Calcium floods the sarcoplasm and binds to troponin molecules leaving active sites.
6. Tropomyosin molecules bind to exposed active sites, linking actin and myosin
2. Thin filaments are pulled over the thick filaments.
5. The muscle fiber shortens and contracts.
Arrange the following steps for contraction in the correct sequence.
creatine phosphate supplies energy to regenerate ATP from ADP and phosphate
The relationship between ATP and creatine phosphate is that
the more active they are, the more heat is released.
Skeletal muscles help maintain body temperature in that
A plank position is part of a yoga/Pilates workout. The person supports the body on the floor in a prone position with the arms and feet supporting the body. It is a little like the "up" position of a push-up, held for 30 to 60 seconds. Contraction of the abdominal muscles in a plank is most likely
The very brief moment following stimulation when a muscle remains unresponsive to additional stimulation is called the
trapezius and latissimus dorsi.
The triangle of auscultation, commonly used to hear sounds of respiratory organs, is located near the border of the
gluteus medius and gluteus minimus.
A gluteal gait, in which a person walks with a waddling limp, is usually caused by a disorder of the
muscle fibers developing new filaments of actin and myosin.
Weightlifting, in which a muscle exerts more than 75% of its maximum tension, stimulates
Layers of dense connective tissue that separate skeletal muscles from each other are called fascia.
A broad, fibrous sheet of connective tissue that attaches the coverings of adjacent muscles is called an
In order to stimulate skeletal muscle fibers, motor neurons release the neurotransmitter
The rhythmic, wavelike motion produced by smooth muscles in tubular visceral organs is called
